1.4. Terminologies and acronyms

This section will define commonly used terms in this manual. These terms are related to Internetworking, and defined in regards to their use with Pro Series.

z MAC address

On a local area network or other network, the MAC (Media Access Control) address is the computer’s unique hardware number. (On an Ethernet LAN, it is the same as the Ethernet address.)

It is a unique 12-digit hardware number, which is composed of 6-digit OUI (Organization Unique Identifier) number and 6-digit hardware identifier number. The Pro Series has the following MAC address template: 00-01-95-xx-xx-xx. The MAC address can be found on the bottom of the original package.

z Host

A user’s computer connected to the network

Internet protocol specifications define “ other computers on the Internet. A host will have a specific “local” or “host number” that, together with the network number, forms its unique IP address.

z Session

A series of interactions between two communication end points that occur during the span of a single connection

Typically, one end point requests a connection with another specified end point. If the specified end point replies, and agrees to the connection, the end points then take turns exchanging commands and data (“

talking to each other”). The session begins when the connection is established at both ends

and terminates when the connection is ended.

z Client/Server

Client/server describes the relationship between two computer programs in which one program, the client, makes a service request from another program, the server, which fulfills the request.

A server is a computer program that provides services to other computer programs on one or many computers. The client is the requesting program or user in a client/server relationship. For example, the user of a Web browser is effectively making client requests for pages from servers all over the Web. The browser itself is a client in its relationship with the computer that is getting and returning the requested HTML file. The computer handling the request and sending back the HTML file is a server.

3. Network Configuration

3.1. IP Configuration

The Pro Series requires a valid IP address to operate within the user’s network environment. If the IP address is not readily available, contact the system administrator to obtain a valid IP address for the Pro Series. Please note that the Pro Series requires a unique IP address to connect to the user’s network. The users may choose one of two Internet protocols in setting up the Pro Series IP address: i.e.,

• Static IP

• DHCP (Dynamic Host Configuration Protocol)

The Pro Series is initially defaulted to STATIC mode, with a static IP address of 192.168.161.5. Table 3-1 shows all the configuration parameters for two protocols of IP configurations. Figure 3-1 shows the

actual web-based GUI to change the user’s IP configuration.

Figure 3-1 IP Configuration

3.1.1. Interfaces

The PSx10W has two network interfaces: one is Ethernet interface and the other is WiFi interface. The two network interfaces don’t work together. Please select a network interface to operate.

3.1.2. Using a Static IP Address

When using a Static IP address, the user must manually specify all the configuration parameters associated with the IP address of the Pro Series. These include the IP address, the network subnet mask, the gateway computer and the domain name server computers. This section will look at each of these in more detail.

Note: The Pro Series will attempt to locate all this information every time it is turned on.

z IP address

A Static IP address acts as a “static” or permanent identification number. This number is assigned to a computer to act as its location address on the network. Computers use these IP addresses to identify and talk to each other on a network. Therefore, it is imperative that the selected IP address be both unique and valid in a network environment.

Note: 192.168.1.x will never be assigned by and ISP (Internet Service Provider). IP addresses using this form are considered private. Actual applications of the Pro Series may require access to public network, such as the Internet. If so, a valid public IP address must be assigned to the user’s computer. A public IP address is usually purchased or leased from a local ISP.

z Subnet mask

A subnet represents all the network hosts in one geographic location, such as a building or local area network (LAN). The Pro Series will use the subnet mask setting to verify the origin of all packets. If the desired TCP/IP host specified in the packet is in the same geographic location (on the local network segment) as defined by the subnet mask, the Pro Series will establish a direct connection. If the desired TCP/IP host specified in the packet is not identified as belonging on the local network segment, a connection is established through the given default gateway.

z Default gateway

A gateway is a network point that acts as a portal to another network. This point is usually the computer or computers that control traffic within a network or a local ISP (Internet service provider). The Pro Series uses the IP address of the default gateway computer to communicate with hosts outside the local network environment. Refer to the network administrator for a valid gateway IP

address.

z Primary and Secondary DNS

The DNS (Domain Name System) server is used to locate and translate the correct IP address for a requested web site address. A domain name is the web address (i.e. www.yahoo.com

) and is usually easier to remember. The DNS server is the host that can translate such text-based domain names into the numeric IP addresses for a TCP/IP connection. The IP address of the DNS server must be able to access the host site with the provided domain name. The Pro Series provides the ability to configure the required IP addresses of both the Primary and Secondary DNS servers addresses. (The secondary DNS server is specified for use when the primary DNS server is unavailable.)

3.1.3. Using DHCP

Dynamic Host Configuration Protocol (DHCP) is a communications protocol that lets network administrators manage and automate the assignment of IP addresses centrally in an organization’ network. DHCP allows the network administrator the ability to supervise and distribute IP addresses from a central point and automatically send a new IP address when a computer is plugged into a different network location. When in static IP mode, the IP address must be entered manually at each computer. If a computer is moved to another network location, a new IP address must be assigned. DHCP allows all the parameters, including the IP address, subnet mask, gateway and DNS servers to be automatically configured when the IP address is assigned. DHCP uses a “lease” concept in assigning IP addresses to a computer. It limits the amount of time a given IP address will be valid for a computer. All the parameters required to assign an IP address are automatically configured on the DHCP server side, and each DHCP client computer receives this information when the IP address is provided at its boot-up. Each time the device is reset, the Pro Series broadcasts a DHCP request over the network. The reply generated by the DHCP server contains the IP address, as well as the subnet mask, gateway address, DNS servers and the “lease” time. The Pro Series immediately places this information in its memory. Once the “lease” expires, the Pro Series will request a renewal of the “lease” time from the DHCP server. If the DHCP server approves the request for renewal, the Pro Series can continue to work with the current IP address. If the DHCP server denies the request for renewal, the Pro Series will start the procedure to request a new IP address from the DHCP server.

Note: While in DHCP mode, all network-related parameters for the Pro Series are to be configured automatically, including the DNS servers

A DHCP sever assigns IP addresses dynamically from an IP address pool, which is managed by the network administrator. This means that the DHCP client, i.e. the Pro Series, receives a different IP address each time it boots up. The IP address should be reserved on the DHCP server side to assure that the user always knows the newly assigned Pro Series address. In order to reserve the IP address in the DHCP network, the administrator needs the MAC address of the Pro Series found on the label sticker at the bottom of the Pro Series.

3.2. WiFi Configuration

The PSx10W has a WiFi interface that supports both 802.1 1b and 802.11g.

3.2.1. Network type

An AP is most often used to connect the PSx10W to the Ethernet. However, it can also be used to connect to the Internet. This type of connection is referred as an “infra mode.”

networks, ”Adhoc mode”, also called “peer-to-peer mode”, is a method for PSx10W devices to directly communicate with each other without an AP. Adhoc mode can be very useful in replacing cables between existing devices with a wireless connection.

3.3. SNMP Configurations

The Pro Series has the SNMP (Simple Network Management Protocol) agent supporting SNMP v1 and v2 protocols. Network managers like NMS or SNMP Browser can exchange information with Pro Series, as well as access required functionality. SNMP protocols include GET, SET, GET–Next, and TRAPs. With these functions, a manager can be notified of significant events (TRAPs), query a device for more information (GET), and make changes to the device state (SET). SNMPv2 adds a GET–Bulk function for retrieving tables of information and security functions. With the SNMP configuration panel, the user can configure MIB-II System objects, access control settings and TRAP receiver settings. The manager configured in this menu can perform both information exchange and action control. Figure 3- shows a SNMP configuration screen via a web interface.

MIB–II System objects configuration sets the System Contact, Name, Location, and Authenticationfailure traps used by the SNMP agent of the Pro Series. These settings provide the values used for the MIB-II sysName, sysContact, sysLocation, sysService and enableAuthenTrap. Brief descriptions of each object are as follows,

z sysContact: Identification of the contact person for the managed system (Pro Series), and a

description of how to contact the person.

z sysName: Name used to identify the system. By convention, this is the fully qualified domain

name of the node.

z sysLocation: The physical location of the system (e.g., Room 384, Operations Lab, etc.). z sysService(Read Only) : A series of values, separated by commas, that indicate the set of

services that the system provides. By default, Pro Series only supports an Application(7) service level.

z EnablePoweronTraps: Indicates whether the SNMP agent process is permitted to generate

power-on traps.

z EnableAuthenTrap: Indicates whether the SNMP agent process is permitted to generate

authentication-failure traps. The value of this object overrides any configuration information; as such, it provides a means whereby all authentication-failure traps may be disabled..

If users need support for adding or modifying MIBs, please contact Sena technical support. For more information about the MIBs and SNMP, see the RFCs 1066, 1067, 1098, 1317, 1318 and

1213.

3.3.2. Access Control Configuration

Access Control defines accessibility of managers to the Pro Series SNMP agent. Only the manager set in this menu can access Pro Series SNMP agent to exchange information and control actions. If there is no specified IP address (all IP address are defaulted to 0.0.0.0), a manager from any host can access the Pro Series SNMP agent.

3.3.3. Trap Receiver Configuration

The Trap receiver defines managers, which can be notified of significant events (TRAP) from the Pro Series SNMP agent.

3.3.4. Management using SNMP

The Pro Series can be managed through the SNMP protocol using NMS (Network Management System) or SNMP Browser. Before using the NMS or SNMP Browser, the user must set the access control configuration properly so that the Pro Series permits host access where the NMS or SNMP Browser is executed. Figure 3- shows a screen shot of a typical SNMP browser with MIB-II OIDs of the Pro Series SNMP agent.

3.4. Dynamic DNS Configuration

When users connect the Pro Series to a DSL line or use a DHCP configuration, the IP address might be changed whenever it reconnects to the network. It can therefore be very difficult to post all related contacts for each new IP address. In addition, if the administrator only has access through the remote console, there is no way to know if an IP address has changed, or what the new IP address is.

A Dynamic DNS service is provided by various ISPs or organizations to deal with the above issue. By using the Dynamic DNS service, users can access the Pro Series through the hostname registered in the Dynamic DNS Server regardless of any IP address change.

By default, the Pro Series only supports Dynamic DNS service offered at Dynamic DNS Network Services, LLC (www.dyndns.org). Contact Sena technical support for issues regarding other Dynamic DNS service providers.

To use the Dynamic DNS service provided by Dynamic DNS Network Services, the user must set up an account in their Members’ user may then add a new Dynamic DNS Host link after logging in to their Dynamic DNS Network Services Members NIC.

After enabling the Dynamic DNS service in the Dynamic DNS Configuration menu, the user must enter the registered Domain Name, User Name, and Password. After applying the configuration change, users can access the Pro Series using only the Domain Name.

3.5. SMTP Configuration

The Pro Series can send an email notification when the number of system log messages reaches to certain value and/or when an alarm message is created due to an issue with serial port data. The user must configure a valid SMTP server send these automatically generated emails. The Pro Series supports three SMTP server types:

• SMTP without authentication

• SMTP with authentication

• POP-before-SMTP

These examples can be seen in Figure 3-3. Required parameters for each SMTP configuration include:

• SMTP server IP address

• SMTP user name

• SMTP user password

• Device mail address

The device mail address specifies the sender’s email address for all log and alarm delivery emails. SMTP servers often check only the sender’s host domain name of the email address for validity. Consequently, the email address set for the device can use an arbitrary username with a registered hostname (i.e. arbitrary_user@yahoo.com The SMTP user name and SMTP user password are required when either SMTP with authentication or POP-before-SMTP mode is selected.

or anybody@sena.com).

3.6. IP Filtering

The Pro Series prevents unauthorized access using an IP address based filtering method. The users can allow one of the following scenarios by changing the parameter settings:

- Any host cannot access a specific service of the Pro Series

- Only one host of a specific IP address can access a specific service of the Pro Series

- Hosts on a specific subnet can access a specific service of the Pro Series

- Any host can access a specific service of the Pro Series

The IP filtering feature is intended to control access to Telnet console, SSH console, NFS, Web server or each port, which may be enabled or disabled. The factory default of the filtering feature is “All services and ports are accessible from any host”.

The meanings of each parameter in IP filtering configuration are as follows,

z Interface

Apply IP filtering rule to the incoming packet of Pro Series. This is fixed parameter as eth0(Read-Only).

z Option and IP address/mask

Input field to describe a specific range of host on the network. The user may allow a host or a group of hosts to access the Pro Series. The user must then enter the IP address and subnet of access. Any user on a remote host must stay in the specified subnet boundary to access the Pro Series. To allow only a specific host to access the Pro Series, enter the IP address of the specific host and just give 255.255.255.255 for the subnet with Normal option. To allow any hosts to have access to the Pro Series, give 0.0.0.0 for both of the IP address and subnet with Normal option also. Refer to Table 3-2 for more details.

서식 있음: 글머리 기호 및 번호 매기기

z Service

Service to which will be applied to the IP filtering rule. User can select one of Telnet, SSH, NFS, HTTP, HTTPS or each serial port

z Chain rule

Set the basic rule for the host to access the Pro Series as one of Accept, Drop or Reject.

Figure 3-42 IP filtering Configuration

The Pro Series provides a policy option. The policy decides how to treat a packet which isn’t determined to be dropped or accepted by IP filtering list. For example, in case there is no IP filtering list and all the services are set to be “Accept all”, the Pro Series won’t respond to any packet whose destination port is not one of the services if the policy is “DROP” or “REJECT.

Figure 3-53 IP filtering policy

The Pro Series also provides users with simple configuration way to block a specific service(s) or serial ports from all hosts. If the user should set any service option as “Drop all” or “Reject all”, then all access to the service from the network will be blocked.

3.7. SYSLOG server configuration

The Pro Series supports the use of a remote message logging service, SYSLOG service for the system and port data logging. To use the remote SYSLOG service, the user must specify the SYSLOG server’s IP address and the facility to be used. Figure 3-7 shows the SYSLOG server configuration page which is located in the Web interface.

삭제됨:

서식 있음: 글머리 기호 및 번호 매기기

Figure 3-75 SYSLOG server configuration

To receive log messages from the Pro Series, the SYSLOG server must be configured as “remote reception allowed”. If there is a firewall between the Pro Series and the SYSLOG server, there must be a rule that allows all outgoing and incoming UDP packets to travel across the firewall. The Pro Series supports SYSLOG facilities from local0 to local7. The user can employ these facilities to save messages from the Pro Series separately in the SYSLOG server. If the SYSLOG service is enabled and the SYSLOG server configuration is properly set up, the user may configure the storage location for the system log or port data log of the Pro Series as SYSLOG server. For more information about the configuration of port/system log storage location, please refer to section, 4.2.8 Port Logging and 5.2 System Logging.

3.8. Locating server

3.8.1. Overview

If users want the Pro Series to work as a server (TCP or UDP), the host acting as a client has to know the IP address of the Pro Series. However, under the dynamic IP address environment such as DHCP, arbitrary IP address can be assigned to the Pro Series, which means special consideration is required to access the current IP address of it. To tackle this problem, the Pro Series can be configured to send its IP address information whenever it is assigned a new IP address or periodically to a specific server called locating server. You can operate a specific host as your locating server or you can use your client host as a locating server simultaneously. No special library or toolkit to implement locating server is provided. You have to implement your own application by using the protocol provided below or contact us.

3.8.2. Locating server configuration

Locating server configuration screen is shown in Figure 3-8. You have to configure locating server IP address, locating server UDP port number and connection time interval as well as to use locating server feature or not. Initially locating server feature is configured as “Disabled”.

When the Pro Series sends its IP address information to the locating server, data format will be as follows:

Description Magic Cookie Data(0) Data(1) … Data(n) Bytes 4 Variable Variable Variable

Value F1-AA-AA-BC

Data(n) format

Note:

Local ports: Each 2 byte data represent current local port setting of the corresponding serial port. Local ports data length of PSx10W should be 2 bytes. Configured local TCP (or UDP) port numbers for each serial port are filled in the serial port number order base, (i.e. TCP or UDP port number for serial port 1 first). If serial port is disabled, the local port number of that serial port is regarded as 0. Example of the P S110W:

If port number = 7001 (1B59h), Local ports data = 1Bh, 59h If serial port is disabled, Local port data = 00h, 00h

Example of the PS210W:

Port1 = 7001 (1B59h), Port2 = 7010 (1B62h), Port3 = Disable, Port4 = 7004(1B5Ch) Local ports data = 1Bh, 59h, 1Bh, 62h, 00h, 00h, 1Bh, 5Ch

3.9. NFS server configuration

The Pro Series supports NFS (Network File System) service for system or port data logging functions. To use this service, the user must specify the IP address of a NFS server and the mounting path on the NFS server. Figure 3-9 displays the NFS server configuration page located in the web configuration interface..

Figure 3-97 NFS server configuration

To store the Pro Series log data to the NFS server, the NFS server must be configured as “read and write allowed”. If there is a firewall between the Pro Series and the NFS server, there must be a rule that allows all outgoing and incoming packets to travel across the firewall. If the NFS service is enabled and the NFS server configuration is properly set up, the user may configure the storage location for the system log or port data log of the If there is a firewall between the Pro Series and the SYSLOG server, there must be a rule that allows all outgoing and incoming UDP packets to travel across the Pro Series as the NFS server. For more information about the configuration of the port/system log storage location, please refer to section, 4.2.8 Port Logging and

5.2 System Logging.

3.10. TCP service configuration

If a TCP session is established between two hosts, the connection should be closed (normally or abnormally) by either of the hosts to prevent the lock-up of the corresponding TCP port. To prevent this type of lock-up situation, the Pro Series provides a TCP “keep-alive” feature. The Pro Series will send packets back and forth through the network periodically to confirm that the network exists . The corresponding TCP session is closed automatically if there’s no response from the remote host. To use the TCP “keep-alive” feature with the Pro Series, the users should configure three parameters as follows:

z TCP keep-alive time:

This represents the time interval between the last data transmission and keep-alive packet

서식 있음: 글머리 기호 및 번호 매기기

삭제됨:

서식 있음: 글머리 기호 및 번호 매기기

삭제됨:

submissions by the Pro Series. These “keep-alive” messages are sent to the remote host to confirm that the session is still open. The default time value is 15 sec.

z TCP “keep-alive” probes:

This represents how many “keep-alive” probes will be sent to the remote host, until it decides that the connection is dead. Multiplied with the “TCP ‘keep-alive’ intervals”, this gives the time that a link is forced to close after a “keep-alive” packet has been sent for the first time. The default is 3 times

z TCP keep-alive intervals:

This represents the waiting period until a “keep-alive” packet is retransmitted. The default value is

5 seconds.

By default, the Pro Series will send the keep-alive packets 3 times with 5 seconds interval after 15 seconds have elapsed since the time when there’s no data transmitted back and forth.

4. Serial Port Configuration

4.1. Overview

The serial port configuration capability allows the user to configure the host mode of each port, serial communication parameters, cryptography, port logging parameters and other related parameters. The serial port’s host mode can be set as any of the following:

z TCP :

The Pro Series operates as a TCP server and client. If the connection is not established, it accepts all incoming connections from any registered remote hosts and connects to the registered remote hosts if there is any data from the serial devices. Otherwise, it will send data back and forth. In summary, the Pro Series will work as if it is virtually connected to the remote host.

z UDP :

The UDP mode operation is similar to that of TCP mode except that it is based on UDP protocol.

z Modem emulation :

Select this mode when the serial device becomes ready to support modem AT commands or users want to perform the session control by using AT commands. Only TCP session is supported.

With the port-logging feature while in console server mode, the data sent through the serial port is transferred to MEMORY or NFS server’s storage. The user can also define keywords for each serial port that will trigger an email or SNMP trap notification. This will enable the user to monitor the data from the attached device.

Using MEMORY to store data will result in loss of all information when the Pro Series is turned off. Use the NFS server to preserve the serial port log data. The serial ports can be configured individually or all at once. Table 4-1 summarizes the configuration parameters related to the serial port configuration.

4.2.3. Host Mode Configuration

The Pro Series operating mode is called the “host mode.” Three host modes are available: TCP mode, UDP mode, Modem emulation mode.

TCP mode

The Pro Series works as both TCP server and client. This mode works for most applications, since it will transfer the data either from serial port or from TCP port. If there is no connection established on a TCP port, the TCP port accepts a connection request from any registered remote hosts and relays the transmitted data to the coupled serial port. If there is any data from the serial port, it connects to the registered remote hosts and redirects the data.

UDP mode

The UDP mode operation is similar to that of TCP mode except that it utilizes UDP protocol.

Modem emulation mode

Select this mode when the serial device already supports modem AT commands or users want to perform the session control by using AT commands. Only TCP session is supported.

Figure 4-4 Host mode configuration (TCP mode)

4.2.3.1. TCP mode

For easier understanding of TCP modes, a simplified State Transition Diagram is often used. And to help users understand the diagram, the TCP state of the Pro Series is briefly described as follows.

[Listen]

It represents “a waiting for a connection request from any registered remote host”. It is a default start-up mode when it is set as TCP mode. [Closed] It means “no connection state”. If the data transfer between a remote host and the Pro Series is completed, the state is changed to this state as a result that either of the remote host or the Pro Series sent a disconnection request. After this, the state is automatically changed to [Listen] mode.

[Sync-Received]

The state is changed from [Listen] to [Sync-Received] if one of the remote hosts has sent a connection request. If the Pro Series accepts the request, the state is changed into [Established]. [Sync-Sent] If the Pro Series has sent a connection request to a remote host, the state is changed from [Closed] to [Sync-Sent]. This state is maintained until the remote host accepts the connection

삭제됨:

서식 있음: 글머리 기호 및 번호 매기기

삭제됨:

request.

[Established]

It represents “an open connection”. If one of the hosts, the remote host or the Pro Series, accepts a connection request from the other, the connection is opened and state is changed into [Established].

[Data]

When it is in [Established] state, data from a host will be transferred to the other one. For easier understanding of the TCP session operation, we called the state as [Data] state when actual data transfer is performed. Actually, the [Data] mode is a part of [Established] state as is described in the RFC 793 [Transmission Control Protocol]. This is a normal state for the data transfer phase of the connection.

The Pro Series works as either TCP server or client according to the situation. This will be the typical mode for most applications, since it will transfer the data either from serial port or from TCP port. The default TCP state is [Listen] which is the same as that of TCP server mode.

1) Typical State Transition

[Listen] --> [Sync-Received] --> [Established] --> [Data] --> [Closed] --> [Listen] Or [Listen] --> [Sync-Sent] --> [Established] --> [Data] --> [Closed] --> [Listen]

The initial state is [Listen]. If there are data coming from the serial port, it will connect to the remote host as a TCP client and then transfer data through the TCP port. If there is incoming connection request from the remote host, it will accept the connection as a TCP server, and then transfer data through the serial port. Thus, users can assume that the Pro Series is always connected to the specified remote host.

2) Operations

Serial data transfer

Whenever the serial device sends data through the serial port of the Pro Series, data will be accumulated on the serial port buffer of the Pro Series. If the buffer is full or the time gap reaches the inter-character timeout (See Options in section 4.4 for details on inter-character timeout), the Pro Series connect to the registered remote host(s). If a TCP session has not been established yet. If the Pro Series succeeds in connecting to the remote host, the data in the serial port buffer will be transferred to the host. Otherwise, all the data stored in the buffer will be cleared.

Session disconnection

The connected session will be disconnected when the remote host sends disconnection request

삭제됨:

or when no data transfer activity is found through the serial port for certain amount of time, which is “Inactivity timeout” (See Options in section 4.4 for details on Inactivity timeout). All the data remained in the serial port buffer will be cleared when it is disconnected.

Connection request from remote host

All the incoming TCP connection requests will be rejected in TCP client mode.

3) Parameters TCP listening port

This is the TCP port number through which a remote host can connect a TCP session, and, send and receive data. Incoming connection request(s) to the ports other than TCP Listening Port will be rejected. The Pro Series does restrict the port number from 1024 to 65535 and if it is set as 0 only outgoing connection is permitted. (TCP server mode)

User authentication

If the User authentication option is enabled, the user can access the port after entering the correct user ID and password. Please refer to the section 5.9 User administration for details of user management.

Telnet protocol

In TCP mode, Pro Series supports Telnet Com Port Control Option (RFC2217 compliant) so that user can control serial parameters like baud rate, data bits and flow control option using his local RFC2217-compliant Telnet client program. (Please refer to section 4.2.6 Serial port parameters for more detail information about serial parameters) Usually this option is used with the RFC2217-compliant COM port redirector so that user can control parameters of serial ports of Pro Series using his serial port application program. For this purpose, SENA OEM version of Serial/IP from Tactical Software, LLC is bundled with Pro Series. Please refer to documentations of Serial/IP for more detail information about using the COM port redirector. (Please refer to section Appendix 5 Using Pro Series with Serial/IP for more detail information)

Max. allowed connection

The Pro Series supports up to 8 multiple connections from external host(s) to the serial port. If there are remote host connections by the remote host list configuration already, possible number of connection will be reduced (Max. allowed connection - remote host(s) connected already). For example, if user set Max. allowed connection as 8 and if there are 3 connections from Pro Series to remote hosts, which are configured in the remote host list, then maximum number of connection from external hosts to a serial port will be reduced to 5. For more detailed information

삭제됨:

for remote host list configuration, please refer to 4.2.4 Remote host configuration section.

Cyclic Connection

If Cyclic Connection function is enabled, the Pro Series will make an attempt to connect to the user-defined remote host(s) at a given interval even if there’s no incoming serial data from the device connected to that serial port. If there is data on the remote host(s) to be sent to serial device, it can be transferred to the serial device via Pro Series’ serial port after the connection is established. Eventually, users can monitor the serial device periodically by making the remote host send the serial command to the Pro Series whenever it is connected to the remote host. This option is useful when users need to gather the device information periodically even if the serial device does not send its data periodically. Figure 4-5 shows the State Transition Diagram of the session operations in TCP mode.

Socket ID

When many Pro Series devices connects a same remote host(s), sometimes it is needed to identify the device. In this case, Socket ID is available for identification of each device. Pro Series send the Socket ID string before starting the data transmission. User can define Socket ID with a

specific string. In TCP mode, specified Socket ID strings are sent once at the time of establishing

TCP connection.

TCP Nagle algorithm

Modern TCP implementations include a mechanism, known as the Nagle algorithm, which prevents the unnecessary transmission of a large number of small packets. This algorithm has proved useful in protecting the Internet against excessive packet loads. However, some applications suffer performance problems as a result of the traditional implementation of the Nagle algorithm.(An interaction between the Nagle algorithm and TCP’s delayed acknowledgement policy can create especially severe problems, through a temporary “deadlock.”) TCP Nagle algorithm can be disabled or enabled through this option.

Inactivity Timeout

When Inactivity Timeout function is enabled, connection between remote host(s) and Pro Series will be closed automatically if there is no data transmission during the value which is set in Inactivity Timeout configuration.

4.2.3.2. UDP mode

The UDP mode operation is similar to that of TCP mode except that it is based on UDP protocol and only one pre-defined remote host is able to communicate with the Pro Series. Users do not have to configure cyclic connection, since UDP is a connectionless protocol.

삭제됨:

Figure 4-6 Host mode configuration (UDP mode)

1) Operations

If a remote host sends a UDP datagram to the one of UDP Local port of the Pro Series, Pro Series first checks whether it is from one of the hosts configured on remote host configuration. If the remote host is one of the hosts configured on remote host configuration, then Pro Series t r ansfers the data t h r o ug h the serial port. Otherwise, the Pro Series discards the incoming UDP datagram. But user can force Pro Series accept all incoming UDP datagram regardless remote host configuration by setting Accept UDP datagram from unlisted remote host parameter as ‘Yes’. If there is any incoming data from the serial port, the Pro Series transfers the data to the remote host defined on remote host configuration. If the remote port is not opened, the Pro Series will not transfer the data.

2) Parameters UDP receiving port

The concept is the same as TCP listening port. See TCP mode parameters in the section 4.2.3.1 for details.

Max. allowed connection

The concept is the same as that of TCP communication. See TCP mode parameters in the section 4.2.3.1 for details.

삭제됨:

Accept UDP datagram from unlisted remote host If Accept unlisted (Accept UDP datagram from unlisted remote host) function is set as ‘No’, Pro Series will accept only incoming UDP datagram from the remote host(s) configured on remote host configuration. On the contrary if Accept unlisted function is set as ‘Yes’, Pro Series will accept all incoming UDP datagram regardless remote host configuration.

Send to recent unlisted remote host

If Send unlisted (Send to recent unlisted remote host) function is set as ‘Yes’, Pro Series sends data to the remote host, which has connected Pro Series recently. Recent unlisted remote host is a remote host, which has accessed a corresponding serial port of Pro Series but is not configured on remote host configuration. Surely, Pro Series also send data to the hosts, which are configured on remote host configuration. If Send unlisted function is set as ‘No’, Pro Series sends data only to the host(s) which are configured on remote host configuration. Pro Series maintains a recent unlisted remote host during the Inactivity Timeout.

Inactivity Timeout

In UDP mode, Inactivity Timeout is used in maintaining recent unlisted remote host. If there is no data transmission between unlisted remote host and serial port of Pro Series during Inactivity Timeout, Pro Series will not send data from a serial port to the recent unlisted remote host again. Namely, Inactivity Timeout in UDP mode is the time maintained recent unlisted remote host list by Pro Series.

NOTE: If user set Inactivity Timeout as 0 in UDP mode, Pro Series does not allow any new connection from/to remote host if the number of current remote host exceeds Max. allowed connection.

Socket ID

4.2.3.3. Modem emulation mode

1) Operations

In modem emulation mode, the serial port process acts as if it is a modem attached to the serial device. It accepts AT modem commands and answers to them, as modems would do. It also handles the modem signals correctly. Modem emulation mode is useful in the following cases.

삭제됨:

When Pro Series connects remote host(s), sometimes it is needed to identify the device using the string. In this case, if user specifies specific strings in Socket ID, Pro Series send these strings first before start the data transmission. User can specifies specific strings as Socket ID.

There already exists a modem attached to the users’ serial device. If users’ serial device already has a modem for phone-line connection, it can be just replaced by the Pro Series for Ethernet connection. What users need to do is to use an IP address (or domain name) and port number instead of phone number as a parameter of ATA/ATDT commands.

It is required to send serial data to the multiple remote hosts.

If the serial device should send data to the multiple hosts, modem emulation mode is required. For example, the first data from the serial device can be sent to the first data acquisition server and the second to the second server. What user device has to do is to change the IP address (or domain name) and port number parameters whenever the device sends ATD(T) XXX command.

By using the modem emulation mode of the Pro Series, users can have their serial device connected to the Ethernet network easily, which is cheaper than using phone line modem. Table 4-2 is a summarized AT command table which is supported by the Pro Series. Figure 4-7 shows the typical case of the serial port command flow when ATDA command is used to connect to the Ethernet network.

Figure 4-7 Typical case of command/data flow of modem emulation mode

In modem emulation mode, user can also set specific phone number to host address/port mapping table. If user set the phone number to host address/port mapping table as shown on Figure 4-8, Pro Series will try to connect to port 7001 of 192.168.1.1 host by the ‘atdt5737772’ command in modem emulation mode.

2) Parameters

Phone number to host address mapping table

In modem emulation mode, user can set a specific phone number to host address/port mapping table. If user set the phone number to host address/port mapping table as shown on Figure 4-8, Pro Series will try to connect to port 6001 of 192.168.0.100 host by the ‘atdt25737772’ command in modem emulation mode.

CONNECT string in non-verbose mode (ATV0) and CONNECT string in verbose mode (ATV1)

In modem emulation mode, the Pro Series responds to the AT command according to result code in Table 4-3 by default. But there are some cases that device requires different form of response code for remote host connection. For example, when the Pro Series connects the remote host, it replies “1”(if ATV0 command is set) or “CONNECT” (if ATV1 command is set) result code by default. But if user needs “12” (if ATV0 command is set) or “CONNECT 9600” (if ATV1 command

삭제됨:

is set) response for this case, he can get the required result after setting CONNECT strings as shown on Figure 4-8.

Respond to AT&Cn, AT&Wn and AT&Zn with For the following three AT commands, AT&Cn, AT&Wn, AT&Zn User can select the response as one of OK or ERROR. Command echo delay(ms) AT commands that are entered by user can be echoed with a delay specified in this menu. This is useful if user uses modem emulation mode in RS485 mode. Default command echo User can disable or enable echo of AT command that is entered by user in this menu. (Same functionality to ATEn command)

Default data mode

User can select the TCP data mode between Raw TCP mode and Telnet binary mode. The Raw TCP means that there is no application protocol over the TCP protocol. The Telnet binary mode means that there is Telnet protocol over the TCP protocol. The Telnet binary mode supports the Telnet COM Port Control Option defined by RFC2217. When selecting this option with a COM Port Redirector compatible with RFC2217, user is able to control the serial port parameter of the Pro Series through a serial port application such as Hyperterminal.

4.2.4. Remote host configuration

Remote host configuration is the list of hosts that will receive data from serial port of Pro Series when there is data transmission from the serial port of the Pro Series. In TCP mode, user can also configure secondary remote host (Backup host) that will receive data from serial port if Pro Series fails to connect to primary remote host. If a connection to the primary remote host can be made, Pro Series dose not send data to secondary remote host until connection to primary remote host failed. And the maximum possible number of primary remote host is limited up to 4 remote connections. In UDP mode, user can only configure a primary remote host because there is no way for Pro Series to check status of primary remote host, so secondary remote host is meaningless. The maximum number of remote host is limited up to 4 in the Pro Series. Figure 4-9 shows Remote host configuration pages of the Web UI. (TCP mode) User can also set any effective domain name as Host IP address in the Remote host configuration.

4.2.5.1. Secure Sockets Layer(SSL) cryptography method

By setting the cryptography method as SSL, the Pro Series can communicate with another device supporting SSLv3 cryptography method during encrypted sessions. SSL was developed by Netscape for use between clients and servers. SSL layers on top of any transport protocol and can run under application protocols such as HTTP. SSL aims to be secure, fast, and adaptable to other Web protocols. SSL provides data security for applications that communicate across networks. SSL is a transport-layer security protocol layered between application protocols and TCP/IP. To initiate SSL sessions, exchange of messages called the SSL handshake is required between two devices (Server and Client). The SSL protocol uses a combination of public-key and symmetric key encryption. Symmetric key encryption is much faster than public-key encryption, but public-key

삭제됨:

서식 있음: 글머리 기호 및 번호 매기기

encryption provides better authentication techniques. The handshake allows the server to authenticate itself to the client using public-key techniques, and then allows the client and the server to cooperate in the creation of symmetric keys used for rapid encryption, decryption, and tamper detection during the session that follows. The details of handshake process step involved can be summarized as follows:

1. The client sends the server the client’

s SSL version number, cipher settings, randomly generated data, and other information the server needs to communicate with the client using SSL.

2. The server sends the client the server’

s SSL version number, cipher settings, randomly generated data, and other information the client needs to communicate with the server over SSL. The server also sends its own certificate and, if the client is requesting a server resource that requires client authentication, requests the client’

s certificate .

3. The client uses some of the information sent by the server to authenticate the server. If the server cannot be authenticated, the user is warned of the problem and informed that an encrypted and authenticated connection cannot be established. If the server can be successfully authenticated, the client goes on to next step.

4. Using all data generated in the handshake so far, the client (with the cooperation of the server, depending on the cipher being used) creates the premaster secret for the session, encrypts it with the server’

s public-key (obtained from the server’s certificate, sent in step 2), and sends the encrypted premaster secret to the server. SSL differ in the way this “shared” master secret is created

5. If the server has requested client authentication (an optional step in the handshake), the client also signs another piece of data that is unique to this handshake and known by both the client and server. In this case the client sends both the signed data and the client’

s own certificate to

the server along with the encrypted premaster secret.

6. If the server has requested client authentication, the server attempts to authenticate the client. If the client cannot be authenticated, the session is terminated. if the client can be successfully authenticated, the server uses its private key to decrypt the premaster secret, then performs a series of steps (which the client also performs, starting from the same premaster secret) to generate the master secret.

7. Both the client and the server use the master secret to generate the session keys, which are symmetric keys used to encrypt and decrypt information exchanged during the SSL/TLS session and to verify its integrity—

that is, to detect any changes in the data between the time

it was sent and the time it is received over the SSL connection.

8. The client sends a message to the server informing it that future messages from the client will be encrypted with the session key. It then sends a separate (encrypted) message indicating that the client portion of the handshake is finished.

9. The server sends a message to the client informing it that future messages from the server will

삭제됨: '

삭제됨: "

삭제됨: '

삭제됨: --

be encrypted with the session key. It then sends a separate (encrypted) message indicating that the server portion of the handshake is finished.

10. The SSL handshake is now complete, and the SSL session has begun. The client and the server use the session keys to encrypt and decrypt the data they send to each other and to validate its integrity.

Figure 4-11 Typical SSL Handshake Process

The Pro Series can act as a SSL server or as a SSL client depending on status of TCP mode. If TCP connection with SSL is initiated from remote host first, Pro Series acts as a SSL server during the SSL handshake process. On the contrary, if TCP connection with SSL is initiated from serial port of Pro Series first, Pro Series acts as a SSL client during the SSL handshake process.

z Client Authentication by certificate (server mode only)

If user selects Client Authentication by certificate option as “Enable”, Pro Series will request the client’s certificate while in SSL handshaking process (Step 2). On the contrary, if user selects Client Authentication by certificate option as “Disable”, Pro Series does not request the client’s certificate while in SSL handshaking process (Step 2).

4.2.6. Serial port parameters

To connect the serial device to the Pro Series serial port, the serial port parameters of the Pro Series should match exactly to that of the serial device attached. The serial port parameters are required to match this serial communication. The parameters required for the serial communication are: UART type, baud rate, data bits, parity, stop bits, flow control DTR/DSR behavior and inter-character timeout.

z Baud rate

The valid baud rate for the Pro Series is as follows:

75, 150, 200, 300, 600, 1200, 2400, 4800, 9600, 14400, 19200, 38400, 57600, 115200, and 230400

The factory default setting is 9600.

z Data bits

Data bits can be between 7 bits and 8 bits. The factory default setting is 8 bits.

삭제됨:

서식 있음: 글머리 기호 및 번호 매기기

삭제됨:

z Parity

Parity can be none, even or odd. The factory default setting is none.

z Stop bits

Stop bits can be between 1 bit and 2 bits. The factory default setting is 1 bit.

삭제됨:

Figure 4-14 Serial parameter configuration

z Flow control

The factory default setting of the flow control is None. Software Flow Control using XON/XOFF and hardware flow control using RTS/CTS are supported by the Pro Series. Software flow control method controls data communication flow by sending special characters XON/XOFF (0x11/0x13) between two connected devices. And hardware flow control method controls data communication flow by sending signals back and forth between two connected devices.

Note:

Flow control is supported only in RS232 and RS422 mode. RS485 mode does not support any kind of flow control method.

z DTR/DSR behavior

Purpose of the DTR/DSR pin is to emulate modem signal control or to control TCP connection state by using serial port signal. The DTR is a write-only output signal, whereas the DSR is a read-only input signal in the Pro Series.

삭제됨:

The DTR option can be set to one of three types: always high, always low or high when TCP/UDP is opened. If the DTR behavior is set to high when TCP/UDP is opened, the state of the DTR pin

will be maintained high if the TCP/UDP connection is established. The DSR input behavior can be set to one of two types: none or allow TCP/UDP connection only by high. If user sets the DSR input behavior as Allow TCP/UDP connection only by HIGH, TCP connection to remote host from Pro Series is made only when the DSR status is changed from low to high. And TCP connection to remote host is disconnected when the DSR status is changed from high to low. And also Pro Series accepts TCP connection from the remote host only when the DSR status is high. In case of UDP mode, Pro Series receives UDP data from the remote host only when the DSR status is high. But In modem emulation mode, the connection to the remote host will be disconnected when the DSR status is changed from high to low regardless of the value of DSR behavior.

Serial device connected to Pro Series can control TCP/UDP connection of Pro Series by

controlling DTR signal of it.

Note:

1. DTR/DSR behavior configuration will not be effective when the modem is enabled.

2. DTR/DSR behavior does not effective in RS422 and RS485 mode.

z Inter-character timeout

This parameter defines the interval the Pro Series fetches the overall serial data from its internal buffer. If there is an incoming data through the serial port, the Pro Series stores data into the internal buffer. The Pro Series transfers data stored in the buffer via TCP/IP, only if the internal buffer is full or if the inter-character time interval reaches the time specified in the inter-character timeout setting. If inter-character timeout is set as 0, then data stored in the internal buffer will be transferred immediately without any delay. Optimal inter-character timeout would be different according to your application but at least it must be larger than one character interval within specified baud rate. For example, assume that the serial port is set to 1200 bps, 8 Data bits, 1 stop bit, and no parity. In this case, the total number of bits to send a character is 10 bits and the time required to transfer one character is

10 (bits) / 1200 (bits/s) * 1000 (ms/s) = 8.3 ms. Therefore, you have to set inter-character timeout to be larger than 8.3 ms. The inter-character timeout is specified in milliseconds.

4.2.7. Modem configuration

The Pro Series supports direct modem connection to the serial port. When user wants to connect to a modem on its serial port, he must configure Modem init-string and DCD behavior on the modem

configuration page. The Pro Series supports modem connection only when host mode is set as TCP mode.

z Enable/Disable modem

By enabling this menu, user can attach a modem directly to the serial port of Pro Series. If this parameter is enabled, Pro Series considers this port will be used for modem use exclusively.

z Modem init-string

User can specify modem initialization string for his modem in Modem init-string parameter. When a serial port is set to modem mode by setting Enable/Disable modem parameter as Enabled, Pro Series sends modem initialization string to the serial port whenever rising edge of DTR pin is detected or parameter related with serial port configuration is changed.

z DCD behavior

If DCD behavior is s et as Allow TCP connection only by HIGH, Pro Series permits a connection from the remote host only when the DCD status of serial port is high. This feature is useful when user want to use a serial port only for dial-in modem mode. In this case, if there is no connection through modem already, Pro Series will not permit a TCP side connection.

z Automatic release modem connection

If Automatic release modem connection is set as Enable, modem connection will be closed by Pro Series if all TCP connections are closed. If this option is set as Disable, modem connection will not be closed by Pro Series even if all TCP connections are closed. Please note that actual phone line connection will be closed if one of modems closes connection. That is, this option can be used for Pro Series to allow disconnection of a modem connection by itself when all TCP connections are closed.

If user wants to use dial-out function, he should set DCD behavior as None because he must be able to access modem connected to a serial port to send dial out command to the modem first.

4.2.8. Port Logging

With the port logging feature, the data sent through the serial port is stored to MEMORY or a mounting point on an NFS server.

z Enable/disable port logging

This parameter defines whether to enable or disable the port-logging feature. The factory default setting is [disabled].

z Port log storage location

The port log data can be stored to the Pro Series’ internal memory or the mounting point on an NFS server. If the internal memory is used to store port log data, the port log data will be cleared when the Pro Series is turned off. To preserve the serial port log data, set the storage location to be the NFS server. To do this, the user must configure the NFS server in advance. Please refer to

the section 3.9 NFS server configuration for details of NFS server configuration.

z Port log buffer size

This parameter defines the maximum amount of port log data to be logged. When using internal memory to store the log data, the total size of the port buffer cannot exceed 10 Kbytes. When using an NFS server to store log data, the maximum port buffer size is unlimited. The user should configure the NFS server to ensure that the port logging system works properly.

Figure 4-16 Port logging configuration

4.2.9. Port event handling configurations

The Pro Series provides a user for a means of monitoring or reacting to data from serial device attached to a serial port of it through Port event handling configuration. Namely, user can define keywords for each serial port that will trigger the email/SNMP notification or command sent to the serial port directly on Port event handling configuration. This will enable the user to monitor the data from the attached device or to manage/control a device attached serial port directly when pre-defined keywords are detected. Also, the status of the connection between the Pro Series and the serial device and the status of the TCP connection between the Pro Series and remote hosts could be monitored and managed as well. Each reaction can be configured individually upon each event. Reaction can be an email delivery, SNMP trap sending, command sending or either combination of all reactions.

z Port event handling

If the user wants to enable port event handling feature, set Port event handling as enable. This is a global parameter so if this feature is disabled, the Pro Series does not take any actions on port events.

삭제됨:

삭제됨:

z Notification interval

To prevent Pro Series from being trapped in handling port event, there is a Notification interval parameter. Pro Series will send notification email or SNMP trap every Notification interval even it detects predefined keyword within Notification inte rval. The smaller value of this parameter will result in immediate response for predefined keyword and heavy usage of system resources. The largest value accepted by user is recommended to prevent system resource usage minimization. NOTE: The port command in keyword response is not affected by this parameter. Port command will be sent immediately when the corresponding keyword is detected.

z Email notification

This parameter enables or disables Email notification feature of the Pro Series. When Pro Series sends Email notification, it uses the SMTP server configured in SMTP server configuration. If the SMTP server is not configured correctly or disabled, Email feature will be disabled. For details of SMTP server configurations and descriptions, please refer to section 3.5 SMTP Configuration.

z Subject of Email

This parameter set the subject of Email that will be sent by Pro Series when pre-defined keyword is detected.

z Recipient’s Email address

This parameter set mail recipient who will receive notification mail when pre-defined keyword is detected.

z SNMP trap notification

This parameter enables or disables SNMP trap notification feature of Pro Series.

z Subject of SNMP trap

This parameter set the subject of SNMP trap that will be sent by Pro Series when pre-defined keyword is detected.

Event keywords

The user can assign event keywords so that the Pro Series takes actions such as sending e-mail notification, sending SNMP trap notification or sending pre-defined command to a serial port if the keyword is detected at the serial port.

z Event keyword

User can specify any words, which he/she wants to set as a keyword.

z Email notification

User can select enable or disable for the Email notification action on keyword selected.

z SNMP trap notification

User can select enable or disable for the SNMP trap notification action on keyword selected.

z Port command

Pro Series supports direct reaction to a device attached to serial port when pre-defined keyword is detected. User can specify command or string, which will be sent to a serial port on this menu.

4.2.10. Copy port configuration

User can copy port configuration of one port to another. There are two methods in copying port configuration. One is “Copy current port configuration to” specified ports and another is “Copy current port configuration from” specified port.

NOTE: Port title, TCP port number and UDP port number are not copied by this function.

7.1. Introduction

The root user ca n access the Linux console command line interface (CLI) of the Pro Series via the serial console or TELENT/SSH. In the CLI, the user can perform standard Linux commands to view the status of the Pro Series, edit the configuration, apply configuration changes.

7.2. Flash partition

The Pro Series internal flash is partitioned as shown in the table below. The user can access files at /var directory at his own risk. Simply accessing these files will not affect the Pro Series after rebooting. However, if the user invokes the command saveconf, the changes in the configuration file will be committed to the internal flash memory area of the Pro Series. This will result in the changes being kept after the reboot sequence. Invalid configuration changes can affect the Pro Series behavior. At worst, it may cause the Pro Series to become inoperable.

Appendix 3. Well-known port numbers

Port numbers are divided into three ranges: Well Known Ports, Registered Ports, and Dynamic and/or Private Ports. Well Known Ports are those from 0 through 1023. Registered Ports are those from 1024 through 49151. Dynamic and/or Private Ports are those from 49152 through 65535. Well Known Ports are assigned by IANA, and on most systems, can only be used by system processes or by programs executed by privileged users. Table A-3 shows some of the well-known port numbers. For more details, please visit the IANA website: http://www.iana.org/assignments/port-numbers

Appendix 4. Guide to the Bios menu program

A 4.1. Overview

The bios menu provides a way to recover the Pro Series unit, by using TFTP, as a disaster recovery option and to diagnose the system hardware. If the user presses the <ESC> key within 3 seconds after the Pro Series unit is powered up, the user will enter the bios menu program. From this menu program, the user can set various system parameters, test system hardware, and perform firmware upgrades.

A 4.2. Main menu

After entering the bios menu program, the user will see following main menu page:

-----------------------------------------------------------------------------

---------------------------------------------------------------------------- Welcome to Boot Loader Configuration page

---------------------------------------------------------------------------- Select menu

1. RTC Configuration

A 4.4. Hardware test menu

Using the Hardware test menu, the user can test hardware components. There are three hardware test modes:

- One time

- Looping (without External test in Auto test)

- Looping (with External test in Auto test)

If the user selects One time, an auto test or each component test is performed just once. In this mode, the ping test to the remote host (server IP address) and UART test are also performed once. If the user s elects Looping (without External test in Auto test), the auto test is performed repeatedly until the user presses the <ctrl-c> keys. In this mode, the ping test to the remote host (server IP address) and UART test are not performed. If the user selects Looping (with External test in Auto test)’, auto test is performed repeatedly until the user presses the <ctrl-c> keys. And, the ping test to the remote host (server IP address) and UART test are also performed repeatedly.

Note:

To perform the test on the Ethernet and UART properly, the user must connect an Ethernet cable to

the Ethernet port of the Pro Series and must plug the loopback connector to all the serial ports of the Pro Series. There must exist a remote host with a valid IP address. The default server IP address is

192.168.0.128 and it can be changed using the [Firmware Upgrade] menu. Otherwise, the test may not be performed properly.
