SLC™ Console Manager User Guide 17

2: Overview

SLC console managers are members of a secure IT management family of products. These products offer systems administrators and other IT professionals a variety of tools to securely access and manage their resources. Lantronix has been an innovator in this market with terminal servers and secure console servers, as well as other remote access devices. The SLC console managers build on that foundation and offer new features and capabilities.

IT equipment can be configured, administered, and managed in a variety of ways, but most devices have one method in common: an RS-232 serial port, sometimes called a console, auxiliary, or management port. These ports are often accessed directly by connecting a terminal or laptop to them, meaning that the administrator must be in the same physical location as the equipment. SLC console managers give the administrator a way to access them remotely from anywhere there is a network or modem connection.

Many types of equipment can be accessed and administered using Console Managers including:

 Servers: Unix, Linux, Windows 2003, and others.  Networking equipment: Routers, switches, storage networking.  Telecom: PBX, voice switches.  Other systems with serial interfaces: Heating/cooling systems, security/building access

systems, UPS, medial devices. The key benefits of using Console Managers:

 Saves money: Enables remote management and troubleshooting without sending a

technician onsite. Reduces travel costs and downtime costs.

 Saves time: Provides instant access and reduces response time, improving efficiency.  Simplifies access: Enables you to access equipment securely and remotely after hours and

on weekends and holidays—without having to schedule visits or arrange for off-hour access.

 Protects assets: Security features provide encryption, authentication, authorization, and

firewall features to protect your IT infrastructure while providing flexible remote access. SLC console servers provide features such as convenient text menu systems, break-safe

operation, port buffering (logging), remote authentication, and Secure Shell (SSH) access. Dial-up modem support ensures access when the network is not available.

SLC Models and Part Numbers

The SLC models offer a compact solution for remote and local management of up to 48 devices, for example, servers, routers, and switches with RS-232C (now EIA-232) compatible serial consoles in a 1U-tall rack space. All models have two Ethernet ports called Eth1 and Eth2 in this document. There are two groups of models with different part numbers - one group of models with a USB port (part number -03) and one group of models with PC Card slots (part number -02).

SLC™ Console Manager User Guide 18

2: Overview

Two Ethernet ports are useful when you want to use one port on a private, secure network and the other on a public, unsecured network.

6: Basic Parameters

This chapter describes how to set the following basic configuration settings for the SLC console manager using the SLC web interface or CLI:

 Network parameters that determine how the SLC console manager interacts with the attached

network

 Firewall and routing  Date and time

Note: If you entered some of these settings using a Quick Setup procedure, you may

update them here.

 Requirements for IP Address Assignment  Network Settings  IP Filters  Routing

Note: The features and functionality described in this chapter specific to PC Card use

are supported on SLC -02 part numbers. The features and functionality specific to USB port use are supported on SLC -03 part numbers.

Requirements for IP Address Assignment

If you assign a different IP address from the current one, it must be within a valid range, unique to your network, and with the same subnet mask as your workstation.

To configure the unit, you need the following information:

Eth1

IP address: ________. ________ . ________ .________ Subnet mask: ________. ________ . ________ .________

Eth2

IP address (optional): ________. ________ . ________ .________ Subnet mask (optional): ________. ________ . ________ .________

Gateway: ________. ________ . ________ .________ DNS: ________. ________ . ________ .________

SLC™ Console Manager User Guide 47

Network Settings

Network parameters determine how the SLC console manager interacts with the attached network. Use this page to set the basic configuration settings for the network ports (Eth1 and Eth2). If you entered some of these settings using a Quick Setup procedure, you may update them here.

Ethernet Bonding

The SLC console manager supports dual Ethernet interfaces. Typically both Ethernet interfaces are configured to work as independent network interfaces and given unique IP addresses and fixed MAC addresses. The Ethernet Bonding feature “bonds” the interfaces together to create a single virtual Network interface to SLC network applications.

All network parameters get configured on the primary Ethernet interface (1). The network application only registers with the Virtual interface (Bond0). In the case of a Ethernet link fault, the Virtual Interface (Bond 0) remains up, the application is completely unaware of the network fault and continues as if there was no fault. During Ethernet link faults an alert (interface trap) could be generated to the System Administrator if SNMP is configured and enabled.

Note: You must configure Static IP addresses.

The virtual interface can be configured to run in one of three modes, and they are:

6: Basic Parameters

 Active Backup—Uses Ethernet 2 as a backup to Ethernet 1. All network parameters get

configured on Ethernet 1. Both ports are connected to the network (preferably different switches for increased network connection reliability), but the Virtual Interface Manager only uses one interface. When the Virtual Interface Manager detects a link-down status on the active port, it switches over to the backup interface making it the primary. When the switch occurs to the backup interface, all Physical Layer communications with the SLC console manager continue using the MAC address of the active interface. The IP stack sees one interface (Virtual Interface bond0) only.

 802.3ad Dynamic Link Aggregation (load-balancing protocol)—Uses both Ethernet interfaces

for transmission. The Virtual Interface (Bond0) Manager uses the protocol to determine which Ethernet interface to use for transmission, based on the Source and Destination MAC address pair and Ethernet interface number. All data continues to get received on the primary Ethernet Interface (1). Both interfaces are connected to the switch. When the Virtual Interface Manager detectes a link-down status on any active interface, it disables the 802.3ad Dynamic Link Aggregation making the active interface the primary.

 Load Balancing (Transmit Load Balancing)—Uses both Ethernet interfaces for transmission

load balancing. The Virtual Interface Manager determines which Ethernet interface to use based on the transmit load of the Ethernet interfaces (typically alternating). All data continues to get received on primary Ethernet Interface (1). Both interfaces are connected to the switch. When the Virtual Interface Manager detects a link-down status on any active interface it disables Load Balancing making the active interface the primary.

To enter settings for one or both network ports:

1. Click the Network tab and the Network Settings option. Figure 6-1 shows the page that displays.

Eth1/Eth2 IPv6 Address

Disabled: If selected, disables the network port. Defaults are Eth1 and Eth2

enabled. Obtain from DHCP: Acquires IP address, subnet mask, hostname and gateway

from the DHCP server. (The DHCP server may not provide the hostname gateway, depending on its setup.) This is the default setting. If you select this option, skip to

Gateway. Obtain from BOOTP: Lets a network node request configuration information from

a BOOTP “server” node. If you select this option, skip to Gateway. Specify: Lets you manually assign a static IP address, generally provided by the

system administrator. Enter an IP address that will be unique and valid on your network. There is no

default. Enter all IP addresses in dot-quad notation. Do not use leading zeros in the fields

for dot-quad numbers less than 100. For example, if your IP address is

172.19.201.28, do not enter 028 for the last segment.

Note: Currently, the SLC console manager does not support configurations with

the same IP subnet on multiple interfaces (Ethernet or PPP).

If specifying an IP address, enter the network segment on which the SLC console manager resides. There is no default.

Address of the port in IPv6 format.

Note: The SLC console manager supports IPv6 connections for a limited set of

services: the web, ssh, and Telnet.

IPv6 addresses are written as 8 sets of 4-digit hexadecimal numbers separated by colons. There are several rules for modifying the address. For example, 1234:0BCD:1D67:0000:0000:8375:BADD:0057 may be shortened to 1234:BCD:1D67::8375:BADD:57.

Eth1/Eth2 Mode Select the direction (full duplex or half-duplex) and speed (10 or 100Mbit) of data

transmission. The default is Auto, which allows the Ethernet port to auto-negotiate the speed and duplex with the hardware endpoint to which it is connected.

Eth1/Eth2 MTU Specifies the Maximum Transmission Unit (MTU) or Maximum Packet Size of

packets at the IP layer (OSI layer 3) for the Ethernet port. When fragmenting a datagram, this is the largest number of bytes that can be used in a packet.

Note: Bonding requires a static IP address.

Gateway

Default IP address of the router for this network.

If this has not been set manually, any gateway acquired by DHCP for Eth1 or Eth2 displays.

All network traffic that matches the Eth1 IP address and subnet mask is sent out Eth1. All network traffic that matches the Eth2 IP address and subnet mask is sent out Eth 2.

If you set a default gateway, any network traffic that does not match Eth1 or Eth2 is sent to the default gateway for routing.

DHCP-Acquired

Gateway acquired by DHCP for Eth1 or Eth2.

IP forwarding enables network traffic received on one interface (Eth1, Eth2, or an external/PC Card/USB modem attached to the SLC console manager with an active PPP connection) to be transferred out another interface (any of the above). The default behavior (if IP forwarding is disabled) is for network traffic to be received but

not routed to another destination. Enabling IP forwarding is required if you enable Network Address Translation (NAT)

for any device port modem or PC Card/USB/ISDN modem. IP forwarding allows a user accessing the SLC console manager over a modem to access the network connected to Eth1 or Eth2.

IP Filters

IP filters (also called rulesets) act as a firewall to allow or deny individual or a range of IP addresses, ports, and protocols. When a network connection gets configured to use an IP filter, all network traffic through that connection gets compared to the rulesets of that filter by precedence. Network traffic may be allowed to pass, it may be dropped without notice, or it may be rejected (sends back an error packet) depending upon the rulesets of the filter.

NFS and SMB/CIFS

If you want to save configuration and logging data to a remote NFS server, access the NFS & Server Message Block/Common Internet File System (SMB/CIFS) page. You can also export configuration and logging data by means of an exported CIFS share.

Mounting an NFS shared directory on a remote network server onto a local SLC directory enables the SLC console manager to store device port logging data on that network server. This configuration avoids possible limitations in the amount of disk space on the SLC device available for logging files. You may also save SLC configurations on the network server.

Similarly use SMB/CIFS, Microsoft file-sharing protocol, to export a directory on the SLC console manager as an SMB/CIFS share. The SLC device exports a single read-write CIFS share called “public,” with two subdirectories:

SLC™ Console Manager User Guide 67

7: Services

 Logs directory, which contains the system logs and the device port local buffers (see System

Logs on page 183

 Config directory, which contains saved configurations and is read-write.

) and is read-only.

The share allows users to access the contents of the directory or map the directory onto a Windows computer. Users can also access the device port local buffers from the CIFS share (see

Device Ports – Logging on page 96).

8: Devices

This chapter describes how to view the device status, configure devices, and use an SLC device port connected to an external device, such as a server or a modem. Chapter 11: Connections describes how to use the Connections page to connect external devices and outbound network connections (such as Telnet or SSH) in various configurations. The Console Port page allows you to configure the console port, if required.

This chapter contains the following sections:

 Connection Methods  Permissions  Device Status  Device Ports  Device Ports – Logging  Console Port  Host Lists  Scripts

Note: The features and functionality described in this chapter specific to PC Card use

are supported on SLC -02 part numbers. The features and functionality specific to USB port use are supported on SLC -03 part numbers.

Connection Methods

A user can connect to a device port in one of the following ways:

1. Telnet or SSH to the Eth1 or Eth2 IP address, or connect to the console port and log into the command line interface. At the command line interface, type the connect direct or connect listen command.

2. If Telnet is enabled for a device port, Telnet to <Eth1 IP address>:< telnet port number> or <Eth2 IP address>:<telnet port number>. The Telnet port number is uniquely assigned for each device port.

3. If SSH is enabled for a device port, SSH to <Eth1 IP address>:<ssh port number> or <Eth2 IP address>:<ssh port number>. The SSH port number is uniquely assigned for each device port.

4. If TCP is enabled for a device port, establish a raw TCP connection to <Eth1 IP address>:<tcp port number> or <Eth2 IP address>:<tcp port number>, where tcp port number is uniquely assigned for each device port.

5. If a device port has an IP address assigned to it, you can Telnet, SSH, or establish a raw TCP connection to the IP address. For Telnet and SSH, use the default TCP port number (23 and 22, respectively) to connect to the device port. For raw TCP, use the TCP port number defined for TCP In to the device port. See Device Ports on page 81.

6. Connect a terminal or a terminal emulation program directly to the device port. If logins are enabled, the user gets prompted for a username and password and logs into the command line interface.

SLC™ Console Manager User Guide 79

For #2, #3, #4, #5, and #6, if logins or authentication are not enabled, the user is directly connected to the device port with no authentication.

For #1 and #6, if logins are enabled, the user is authenticated first, and then logged into the command line interface. The user login determines permissions for accessing device ports.

Permissions

There are three types of permissions:

 Direct (or data) mode: The user can interact with and monitor the device port (connect

direct command).

 Listen mode: The user can only monitor the device port (connect listen command).  Clear mode: The user can clear the contents of the device port buffer (set log <port>

clear buffer command).

The administrator and users with local user rights may assign individual port permissions to local users. The administrator and users with remote authentication rights assign port access to users authenticated by NIS, RADIUS, LDAP, Kerberos and TACACS+.

Note: Check the serial device equipment settings and documentation for the proper

settings. The device port and the attached serial device must have the same settings.

Baud Enables the speed (baud rate) with which the device port exchanges data with the

attached serial device. From the drop-down list, select the baud rate. Most devices use 9600 for the administration port, so the device port defaults to this value. Check the equipment settings and documentation for the proper baud rate.

Data Bits Enables the number of data bits used to transmit a character. From the drop-down

list, select the number of data bits. The default is 8 data bits.

Stop Bits Enables the number of stop bits used to indicate that a byte of data has been

transmitted. From the drop-down list, select the number of stop bits. The default is

Parity Select the parity for detecting simple, single-bit errors from the drop-down list. The

default is none.

Enable Logins Displays a login prompt and authenticates users for serial devices connected to the

device port. Successfully authenticated users are logged into the command line interface. The default is disabled and is the correct setting if the device port is the endpoint for a connection.

Flow Control Enables the method to prevent buffer overflow and loss of data. The available

methods include none, xon/xoff (software), and RTS/CTS (hardware). The default is none.

Max Direct Connects

Show Lines on Connecting

Enables the maximum number of simultaneous connections for a device port from 1 to 10. The default is 1.

Enables a number of lines of buffered data when the serial port connects to the SLC console manager. When enabled, the user can use the connect direct command using CLI or connect directly to the port using Telnet or SSH. The output is up to 24 lines.

For example, an SLC device issues a connect direct device 1 command to connect port 1 to a Linux server. Then the SLC console manager user gets a directory with the ls command exits the connection. When the SLC device user issues another direct connect device 1”, the output of the ls command (or some portion of it) is output again, so the user can know what state the server was left in.

Hardware Signal Triggers

Check DSR on Connect

Disconnect on DSR

If this setting is enabled, the device port only establishes a connection if DSR (Data Set Ready) is in an asserted state. DSR should already be in an asserted state, not in transition, when a connection attempt is made. Disabled by default unless dialin, dial-out, or dial-back is enabled for the device port.

If a connection to a device port is currently in session, and the DSR signal transitions to a de-asserted state, the connection disconnects immediately. Disabled is the default unless dial-in, dial-out, or dial-back is enabled for the device port.

Mode The format in which the data flows back and forth:

 Text: In this mode, the SLC console manager assumes that the modem will be

used for remotely logging into the command line. Text mode can only be used for dialing in or dialing back. Text is the default.

 PPP: This mode establishes an IP-based link over the modem. PPP

connections can be used for dial-out (e.g., the SLC device connects to an external network), dial-in (e.g., the external computer connects to the network that the SLC console manager is part of), dial-back (dial-in followed by dial-out), dial-on-demand, CBCP server or CBCP client.

Initialization Script Commands sent to configure the modem may have up to 100 characters. Consult

your modem’s documentation for recommended initialization options. If you do not specify an initialization script, the SLC uses a default initialization string of AT S7=45 SO=0 L1 V1 X4 &D2 &c1 E1 Q0.

Note: We recommend that the modem initialization script always be preceded

with AT and include E1 V1 x4 Q0 so that the SLC console manager may properly control the modem.

Modem Timeout Timeout for all modem connections. Select Yes (default) for the SLC device to

terminate the connection if no traffic is received during the configured idle time. Enter a value of from 1 to 9999 seconds. The default is 30 seconds.

Caller ID Logging Select to enable the SLC console manager to log caller IDs on incoming calls.

Disabled by default.

Note: For the Caller ID AT command, refer to the modem user guide.

Modem Command Modem AT command used to initiate caller ID logging by the modem.

Note: For the AT command, refer to the modem user guide.

Dial-back Number Users with dial-back access can dial into the SLC device and enter their login and

password (for text mode) or authenticate via PAP or CHAP (for PPP mode). Once the SLC console manager authenticates them, the modem hangs up and dials them back.

Select the phone number the modem dials back on -a fixed number or a number associated with their login. If you select Fixed Number, enter the number (in the format 2123456789).

The dial-back number is also used for CBCP client as the number for a userdefined number. For more information, see Modem State Parameters on page

Port Status and Counters

Port Status and Counters list the status of signals and interfaces. SLC console manager updates and increments the port counters as signals change and data flows in and out of the system. These counters help troubleshoot connections or diagnose problems because they give the user an overview of the state of various parameters. By setting them to zero and then re-checking them later, the user can view changes in status. See Figure 8-5 for an example.

The chart in the middle of the page displays the flow control lines and port statistics for the device port. The system automatically updates these values. To reset them to zeros, select the Zero port counters checkbox in the IP Settings section of the page.

Device Ports – Logging

The SLC products support port buffering of the data on the system's device ports as well as notification of receiving data on a device port. Port logging is disabled by default. You can enable more than one type of logging (local, NFS file, email/SNMP, USB port, or PC Card) at a time. The buffer containing device port data is cleared when any type of logging is enabled.

Local Logging

If local logging is enabled, each device port stores 256 Kbytes (approximately 400 screens) of I/O data in a true FIFO buffer. You may view this data (in ASCII format) at the CLI with the show locallog command or on the Device Ports – Logging web page. Buffered data is normally stored in RAM and is lost in the event of a power failure if it is not logged using an NFS mount solution. If the buffer data overflows the buffer capacity, only the oldest data is lost, and only in the amount of overrun (not in large blocks of memory).

NFS File Logging

Data can be logged to a file on a remote NFS server. Data logged locally to the SLC console manager is limited to 256 Kbytes and may be lost in the event of a power loss. Data logged to a file on an NFS server does not have these limitations. The system administrator can define the directory for saving logged data on a port-by-port basis and configure file size and number of files per port.

The directory path must be the local directory for one of the NFS mounts. For each logging file, once the file size reaches the maximum, a new file opens for logging. Once the number of files reaches the maximum, the oldest file is overwritten. The file naming convention is: <Device Port Number>_<Device Port Name>_<File number>.log.

Examples: 02_Port-2_1.log

02_Port-2_2.log

02_Port-2_3.log 02_Port-2_4.log 02_Port-2_5.log

PC Card Logging

Note: The PC Card logging feature is only supported on SLC -02 part numbers.

Data can be logged to a PC Card Compact Flash that is loaded into one of the PC Card slots on the front of the SLC device and properly mounted. Data logged locally to the SLC console manager is limited to 256 Kbytes and may be lost in the event of a power loss. Data logged to a PC Card Compact Flash does not have these limitations. The system administrator can define the file size and number of files per port. For each logging file, once the file size reaches the maximum, a new file opens for logging. Once the number of files reaches the maximum, the oldest file is overwritten. The file naming convention is: <Device Port Number>_<Device Port Name>_<File number>.log.

Examples: 02_Port-2_1.log

02_Port-2_2.log 02_Port-2_3.log 02_Port-2_4.log 02_Port-2_5.log

USB Port Logging

Note: The USB port logging feature is only supported on SLC -03 part numbers.

Data can also be logged to an thumb drive that is loaded in the USB port. Logged data to the USB port is limited to 2048 bytes and 10 files. The system administrator can define the file size and number of files per port. For each logging file, once the file size reaches the maximum, a new file opens for logging. Once the number of files reaches the maximum, the oldest file is overwritten. The file naming convention is: <Device Port Number>_<Device Port Name>_<File number>.log. See Chapter 10: USB Port for configuration tasks and Chapter 15: Command Reference for the commands, specifically the USB Commands section.

Email/SNMP Notification

The system administrator can configure the SLC console manager to send an email alert message indicating a particular condition detected in the device port log to the appropriate parties or an SNMP trap to the designated NMS (see Chapter 7: Services ). The email or trap is triggered when a user-defined number of characters in the log from your server or device is exceeded, or a specific sequence of characters is received.

Use the Device Ports – Logging page to set logging parameters on individual ports.

Syslog Logging

Data can be logged to the system log. If this feature is enabled, the data will appear in the Device Ports log, under the Info level. The log level for the Device Ports log must be set to Info for the data to be saved to the system log (see Chapter 7: Services ).

Email Traps

Email/Traps Select the checkbox to enable email and SNMP logging. Email logging sends an

email message to pre-defined email addresses or an SNMP trap to the designated NMS (see 7: Services) when alert criteria are met. Disabled by default.

Send Select notification type to send: Email, SNMP, or Both. Email is the default. Email

and SNMP logging must be enabled for this feature to work.

Trigger on Select the method of triggering a notification:

Byte Count: A specific number of bytes of data. This is the default. Text String Recognition: A specific pattern of characters, which you can define

by a regular expression.

Note: Text string recognition may negatively impact SLC performance,

particularly when regular expressions are used.

Byte Threshold Sets the threshold for the number of bytes of data the port receives before the SLC

console manager captures log data and sends a notification. The default is 100 bytes.

In most cases, the console port of your device does not send any data unless there is an alarm condition. After the SLC device receives a small number of bytes, it perceives that your device needs some attention. The SLC console manager notifies your technician when that point has been passed, and the notification includes the logged data.

For example, a threshold preset at 30 characters means that as soon as the SLC device receives 30 bytes of data, it captures log data and sends an email regarding this port.

Text String Sets the specific pattern of characters the SLC console manager must recognize

before sending a notification to the technician about this port. The maximum is 100 characters. You may use a regular expression to define the pattern. For example, the regular expression “abc[def]g” recognizes the strings abcdg, abceg, abcfg.

The SLC device supports GNU regular expressions; for more information, see:

 http://www.codeforge.com/help/GNURegularExpr.html  http://www.delorie.com/gnu/docs/regex/regex.html

Email Delay Sets a time limit of how long (in seconds), after the SLC console manager detects

the trigger, that the device port captures data before closing the log file (with a fixed internal buffer maximum capacity of 1500 bytes) and sending a notification. The default is 60 seconds.

Restart Delay Sets the number of seconds for the period after the notification has been sent

during which the device port ignores additional characters received. The data is simply ignored and does not trigger additional alarms until this time elapses. The default is 60 seconds.

Email to Sets the complete email address of the message recipients for each device port.

Each device port has its own recipient list. To enter more than one email address, separate the addresses with a single space. You can enter up to 128 characters.

SLC™ Console Manager User Guide 99

8: Devices

Email Subject Input a subject text appropriate for your site. May have up to 128 characters.

The email subject line is pre-defined for each port with its port number. You can use the email subject to inform the desired recipients of the problem on a certain server or location (e.g., server location or other classification of your equipment). This is helpful if the email message goes to the system administrator’s or service technician's mobile or wireless device (e.g., text messaging by means of email).

Note: The character sequence%d anywhere in the email subject is replaced with

the device port number automatically.
