1: Introduction

The Lantronix MSS family of Device Servers allows you to network-enable a variety of serial devices that were not originally designed to be networked: personal computers, terminals, modems, industrial machinery, and more. This capability brings the advantages of remote management and data accessibility to thousands of serial devices.

The MSS4 offers a solution for almost every networking need. All MSS4 models provide four serial ports, which are capable of RS-232, RS-422, and RS-485 communications, and a 10/100BASE-T Ethernet port. In addition, certain models of the MSS4 include a 100BASE-FX fiber link Ethernet port and two PC card slots. The slots can be used for

802.11 wireless Ethernet, flash storage, and modem cards.

Note:

Parts of this manual assume knowledge of the IEEE 802.11 Standard governing wireless networking. If you are not familiar with wireless networking concepts and implementation, please refer to the Standard or the documentation that came with your wireless PC card.

Throughout this manual, the MSS4 may be referred to as the

MSS Features Introduction

1.2 MSS Features

◆

TCP/IP and UNIX Compatibility The MSS supports a variety of TCP/IP features, including Telnet, Rlogin, UDP,

DNS, SNMP, WINS, FTP, DHCP, BOOTP, RARP, and HTTP. Connectivity

◆

The MSS can connect serial devices directly to a 10/100BASE-T or 100BASE-FX wired Ethernet network or an 802.11 wireless Ethernet network.

Ease of Use

◆

The MSS4 has a simple but powerful command interface for both users and system managers. The MSS Local mode supports command line editing and command line recall. An extensive

The EZWebCon utility (provided on the CD-ROM) allows you to configure the MSS from any host machine running the Java Virtual Machine (JVM). It also allows remote host logins into the MSS, which are similar to Telnet logins.

Help

facility is included.

The Lantronix ThinWeb Manager, a set of HTML pages stored on the MSS, allows you to configure server information via a JavaScript-enabled web browser. For more information, see

◆

Remote Configuration

command line followed by a question mark for help on what is appropriate at that particular point.

Note:

◆

Reloadable Operating Software

See the MSS Reference Manual for more information.

The MSS stores its operating code in Flash ROM, which means that it does not have to download code at boot time. If necessary, you can upgrade the MSS’s operating code to support additional features as newer code becomes available. Also, you can configure the MSS to request a downloaded configuration file at boot time.

Introduction TCP/IP Support

Security

◆

The MSS includes several configurable security features:

❍

Automatic session logouts when a port is disconnected or a device is turned off.

❍

Password protection for privileges, ports, services, maintenance commands, and the remote console.

❍

An IP security table, which allows the MSS manager to restrict incoming and outgoing TCP/IP connections to certain ports and hosts. This allows managers to restrict MSS access to a particular local network segment or host.

Diagnostics

◆

Power-up and interactive diagnostics help system managers troubleshoot network and serial line problems.

SDK Support

◆

The MSS supports the Lantronix Software Developer Kit (SDK), which allows users to customize the MSS and add functionality. For more information about the SDK, please contact Lantronix directly.

Note:

The SDK does not allow users to configure custom PC card support.

1.3 TCP/IP Support

The MSS supports the TCP/IP network protocol. A network protocol is a method of communicating over Ethernet. The protocol specifies a certain arrangement of data in the Ethernet packets, and provides different services for its users.

TCP/IP support includes Telnet, Rlogin, UDP, DNS, and WINS. The Telnet terminal protocol is an easy-to-use interface that creates terminal connections to any network host supporting Telnet. Rlogin is a protocol that allows users to initiate a TCP/IP login session. UDP (User Datagram Protocol) is a connectionless protocol that results in smaller packet headers, no session overhead, and the ability to send to multiple hosts. The MSS also supports the use of Domain Name Servers (DNS), allowing a network nameserver to translate text node names into numeric IP addresses. For WINS support, the MSS can be configured to announce itself as a WINS node.

The MSS also implements basic Simple Network Management Protocol (SNMP) functionality. SNMP commands enable users, usually system administrators, to get information from and control other nodes on a local area network (LAN), and respond to queries from other network hosts. The MSS allows configuration of one community name with read/write access. Instructions for SNMP configuration are available in the section of this guide, page 4-5.

2.2 Installing in a Wired Network

The MSS should be positioned close to the device it will be servicing. Since powering down the unit will terminate any active sessions, it may be desirable to place the server in a location secure from user access. Also be aware of the unit’s environmental operating limits and cabling requirements. See Appendix C and Appendix E for details.

The following diagram shows a properly-installed MSS in a wired Ethernet network. The numbers in the diagram refer to the installation steps in this section.

for RS-232 networking. A Connect one end of a serial cable to either one of the MSS DB9 connectors or

screw terminal blocks (depending on the model). See Appendix C for MSS connector pinout information.

Note: For the first connection, you may want to connect a serial terminal to

the console port, designated as the first serial port. This will allow you to verify that your server is working and to configure the necessary network settings. The console port is initially set for 9600 baud, 8 data bits, one stop bit, and no parity.

2-5

Installing in a Wired Network Installation

When using a screw terminal block, you may have to connect from 2 to 6 wires depending upon the desired MSS usage mode. Do not over-tighten the screws, but make sure the wire is secure in the block.

and chassis ground.

Supply power to the MSS by connecting the power cube end of the power cable to a standard wall outlet.

When the MSS receives power, it will begin a three-step boot process.

❍

The MSS runs through a set of power-up diagnostics for approximately five seconds. The OK and

Serial

LEDs should show varying patterns corresponding

to the test being run.

Note:

If there is a valid connection to a wired Ethernet network, the Link LED should remain solid green or yellow once the unit has completed booting.

Installation Installing PC Cards

❍ The MSS tries to obtain TCP/IP configuration information via DHCP, BOOTP,

and/or RARP. This procedure takes approximately 40 seconds if no hosts answer the request, and boot messages will be sent to the console port. The OK LED will blink green approximately three times per second, and occasionally yellow as packets are sent and received.

Note: For more information on BOOTP, RARP, or DHCP, refer to your

operating system’s documentation.

❍ The MSS determines if the code in the Flash ROMs is valid. If so, it loads the

code and begins normal execution. This step takes approximately five seconds.

Once the MSS is running normally, the Link LED should be solidly lit to indicate a functioning wired Ethernet connection and the OK LED should blink once every two seconds.

4 Supply power to the attached serial device(s), if necessary. 5 Ensure the MSS is working. There are a couple ways to check:

❍ Wait for approximately 30 seconds after powering the unit up. If the Link LED

is solidly lit and the OK LED blinks green once every two seconds, the MSS is operating normally.

❍ If you have connected a serial terminal to the console port, press the Return

key. You should see several lines of start-up messages followed by a Local> prompt.

2.3 Installing PC Cards

The following sections explain how to install different kinds of cards in the MSS PC card slots. Not all PC card types or brands are supported. Check the Lantronix web site for a complete list of currently supported technologies.

2.3.1 Installing an 802.11 Card

Although 802.11 networking is enabled by default, you may need to configure other 802.11 settings before the wireless card will work properly. To view your current 802.11 configuration, enter the Show 80211 command. This command may also be useful if you experience any problems with your wireless network. See 802.11 Configuration on page 416 for more details.

Note: You cannot have more than one 802.11 card installed in the MSS at

one time.

1 Power off the MSS by removing the plug from the outlet. 2 Insert a supported 802.11 card into one of the PC card slots. 3 Power up the MSS by plugging the power supply back in the outlet.

The MSS should begin its normal boot process. Once the process is complete, one of the PC Card LEDs should remain lit as long as there is an 802.11 card inserted in the corresponding PC card slot.

❍ When the PC card LED corresponding to the installed card is solid green, the

MSS is ready for use.

❍ If your PC card LED is any other color, refer to Table 2-1 on page 2-3 for

information on what that color means.

2.3.2 Installing an ATA Flash Card

Follow these steps to properly install supported ATA flash and disk storage cards.

1 Power off the MSS by removing the plug from the outlet. 2 Insert a supported ATA Flash card into one of the PC card slots. 3 If desired, insert another supported ATA Flash card into the other PC card slot. 4 Power up the MSS by plugging the power supply back in the outlet.

The MSS should boot up normally.

2-8

Installation Installing PC Cards

❍ If a PC card LED is a solid green, the ATA card in the corresponding slot is

ready for use.

❍ If a PC card LED blinks green, the ATA card in the corresponding slot must be

formatted before it can be used. Proceed to Formatting an ATA Flash Card on page 4-22 for details.

❍ If a PC card LED is any other color, refer to Table 2-1 on page 2-3 for

information on what that color means.

2.3.3 Installing a Modem Card

An installed modem card will appear as an additional serial port on the MSS. If only one card is installed, the card will appear as Port 5 regardless of which slot it is in. If two cards are installed, the card installed in the top slot (slot 1) will appear as Port 5 and the card in the bottom slot (slot 2) will appear as Port 6.

If you are an SDK user, you can access the port by using device “tt4” for port 5 or “tt5” for port 6.

Follow these steps to properly install supported modem cards.

1 Power off the MSS by removing the plug from the outlet.. 2 Insert a supported modem card into one of the PC card slots. 3 If desired, insert another supported modem card into the other PC card slot. 4 Power up the MSS by plugging the power supply back in the outlet.

The MSS should boot up normally.

For instructions on how to use the modem card, see Modem Cards on page 4-22.

3: Getting Started

This chapter covers all of the steps needed to get the MSS on-line and working. There are three basic methods you can use to log into the MSS and begin configuration:

◆ Incoming (Remote) Logins: EZWebCon is the preferred method for initial MSS

configuration. Users can also use the MSS’s internal HTTP server via a standard web browser. After the initial configuration, the MSS can be accessed remotely across TCP/IP networks through Telnet connections. Incoming connections also include network socket port connections (ports 2001-2004 and 3001-3004).

◆ Serial Port Logins: Users can connect a terminal directly to one of the serial ports,

◆ Remote Console Logins: TCP/IP users can make a Telnet connection to the remote

console port (port 7000).

Consider the following points before you log in and configure the MSS:

◆ Most configuration commands require privileged user status. Connecting a terminal

to a serial port or logging into the remote console port does not automatically create privileged user status—you must enter the Set Privileged command to become the privileged user (see Privileged Password on page 3-2).

◆ The MSS IP address must be configured before any TCP/IP functionality is

available (see IP Address Configuration on page 3-3).

◆ Only one person at a time may be logged into the remote console port (port 7000).

This eliminates the possibility of several people simultaneously attempting to configure the MSS.

◆ Although passwords can be required, remote console logins cannot be disabled. This

ensures that the system manager will always be able to access the unit.

3.1 System Passwords

The MSS has both a privileged password and a login password. These passwords have default settings and are discussed in the following sections.

Note: Default passwords pose a security risk and should be changed as soon

as possible. This is especially true of the privileged password.

3-1

System Passwords Getting Started

3.1.1 Privileged Password

Only the privileged user can change server or port settings. To become the privileged user, enter the Set Privileged command, followed by the privileged password. The default privileged password is system.

Figure 3-1: Set Privileged Command

Local> SET PRIVILEGED Password> system (not echoed)

If another user is currently the privileged user for the MSS, use the Set Privileged Override command to forcibly become the privileged user. To relinquish privileged status,

enter the Set Noprivileged command. The privileged password can be changed with the Change Privpass command. Specify a

new password of up to six alphanumeric characters. Note that only the privileged user can change the privileged password.

Figure 3-2: Changing Privileged Password

Local> SET PRIVILEGED Password> system (not echoed) Local>> CHANGE SERVER PRIVPASS “walrus”

3.1.2 Login Passwords

Login passwords for all connections except remote console logins (port 7000) are disabled by default. The login password is always required for remote console logins. The default login password for all connections is access.

To specify a new login password, use the Change Server Loginpass command. You will be prompted to enter a new password of up to six alphabetic characters. Note that you must be the privileged user (i.e. you must enter the Set Privileged command) to change the login password.

Getting Started IP Address Configuration

3.1.2.1 Serial Port Logins

To require a password for any connections to the MSS from its serial ports, enable password protection with the Change Password Protect Enabled command. The command allows you to specify the serial ports for which you want to provide password protection.

Figure 3-4: Enabling Password Protection for Serial Port Logins

Local>> CHANGE PORT 1-4 PASSWORD PROTECT ENABLED

3.1.2.2 Telnet and Rlogin Connections

To require a password for Telnet and Rlogin connections, enter the Change Server Incoming Password command.

Figure 3-5: Enabling Password Protection for Telnet/Rlogin Connections

Local>> CHANGE SERVER INCOMING PASSWORD

3.1.2.3 Network Socket Connections

To enable the login password for network socket connections, enter the Change Password Incoming Enabled command. The command allows you to specify the serial ports for

which you want to provide password proection.

Figure 3-6: Enabling Password Protection for Network Socket Connections

Local>> CHANGE PORT 2 PASSWORD INCOMING ENABLED

3.2 IP Address Configuration

Note: When you set an IP address, you may also need to change the subnet

mask from the default subnet configuration. See Subnet Mask on page 4-2 for more information.

3.2.1 Using EZWebCon

Note: If your version of EZWebCon is earlier than v.2.0, refer to the Readme

that was included with it.

Use the following steps to assign an IP address using EZWebCon.

1 Start EZWebCon. Instructions for installing, running, and using EZWebCon can be

found on the distribution CD-ROM.

2 From the Action menu, select Assign IP Address.

3-3

IP Address Configuration Getting Started

3 Enter or change the IP-related settings:

A For Ethernet Address, enter the number that appears on the bottom label of

your MSS.

B For IP Address, enter the desired IP address to use for this MSS. C For Subnet Mask, change the values provided only if you wish to use a mask

other than the default. The default value should be correct in most cases.

D For Loadhost, enter the IP address of the loadhost where you intend to store

your operating code and SDK files (if used).

4 Click OK. 5 Reboot the MSS. EZWebCon will let you know whether the configuration was

successful.

3.2.2 Using ARP and Ping

The ARP/ping method is available under UNIX and Windows. If the MSS has no IP address, it will set its address from the first directed IP packet it receives.

On a UNIX host, create an entry in the host’s ARP table and substitute the intended IP address and the hardware address of the server, then ping the server (see Figure 3-7). This process typically requires superuser privileges.

Figure 3-7: Entering ARP and Ping (UNIX)

# arp -s 192.0.1.228 00:80:a3:xx:xx:xx % ping 192.0.1.228

On a Windows host, type ARP -A at the DOS command prompt to verify that there is at least one entry in the ARP table. If there is no other entry beside the local machine, ping another IP machine on your network to build the ARP table. This has to be a host other than the machine on which you're working.

Use the following commands to ARP the IP address to the MSS and make the MSS acknowledge the IP assignment.

Figure 3-8: Entering ARP and Ping (Windows)

C:\ ARP -S 192.0.1.228 00-80-A3-XX-XX-XX C:\ PING 192.0.1.228

Note:

There should be replies from the IP address if the ARP command worked.

3-4

Getting Started IP Address Configuration

When the MSS receives the ping packet, it will notice that its IP address is not set and will send out broadcasts to see if another node is using the specified address. If no duplicate is found, the server will use the IP address and will respond to the ping packet.

The MSS will not save the learned IP address permanently. This procedure is intended as a temporary measure to enable EZWebCon to communicate with the server, allow configuration with a web browser, or allow an administrator to Telnet into the MSS. Once logged in, the administrator can enter the Change IPaddress command to make the address permanent.

3.2.3 Using a DHCP, BOOTP, or RARP Reply

A host-based DHCP, BOOTP, or RARP server can provide information for the MSS to use to configure an IP address when the unit boots. See the host-based documentation pages for configuration information. Keep in mind that many BOOTP daemons will not reply to a BOOTP request if the download file name in the configuration file does not exist. If this is the case, create a file in the download path to get the BOOTP daemon to respond.

BOOTP and RARP are enabled by default on the MSS. If you wish to disable them, use the Change BOOTP Disabled and Change RARP Disabled commands. To enable DHCP, use the Change DHCP Enabled command.

3.2.4 Using the Serial Console

Connect a terminal to the serial console port and press the Return key. If the MSS is functioning normally, you will see the Local> prompt. Become the privileged user and enter the Change IPaddress command.

Figure 3-10: Entering the IP Address at the Local Prompt

Local> SET PRIVILEGED Password> system (not echoed) Local>> CHANGE SERVER IPADDRESS 192.0.1.228

3-5

Incoming Logins Getting Started

If the MSS encounters an Ethernet network problem while booting it will send an alert message to the console and wait ten seconds to detect serial port activity before attempting to finish booting. If you press the Return key when the error message is displayed, you will access the Boot> prompt.

If the MSS fails to properly download code and displays a “will try again” message, you can access the Boot> prompt by pressing the Return key. You can then enter the Change Server IPaddress command at the Boot> prompt to set the unit’s IP address.

Note: For more information on Boot Configuration Program (BCP)

commands, see the Troubleshooting appendix.

3.3 Incoming Logins

Incoming Telnet logins, including connections to network socket ports and the remote console, are enabled by default. This behavior can be changed with the Change Incoming command and one of the following parameters:

Telnet Enables incoming Telnet logins None Disables all incoming logins

For security reasons, you may wish to disable incoming logins. Incoming logins for a port can be disabled with the Change Access command (see Access Mode on page 4-9 for more information).

Note: Access to the remote console port can never be disabled.

If you do not want to completely disable incoming logins, you can configure the MSS to require a login password for incoming connections with various commands, depending on the type of incoming connection. See Login Passwords on page 3-2 for more information.

3.3.1 TCP/IP Logins

3.3.1.1 Web Browser Login and Configuration

If your MSS has an IP address, you can log into it using a standard web browser with Java enabled. Simply type the MSS IP address or resolvable text name into the browser’s URL/ Location field.

Figure 3-11: Sample Web Browser Login

3-6

Getting Started Incoming Logins

Once you have connected to the MSS, you will see the Lantronix ThinWeb Manager interface. Use the left-hand menu to navigate to subpages where you can configure important settings and view statistics and other server information.

Figure 3-12: ThinWeb Manager Interface

3.3.1.2 EZWebCon Login and Configuration

If you are on a TCP/IP network, you can log into and configure the MSS with EZWebCon. The program offers a simple interface that prompts you for the information necessary to configure the server. Instructions for installing, running, and using EZWebCon are included on the CD-ROM.

3.3.1.3 Telnet

To log into the MSS, type telnet followed by the MSS IP address. The MSS must have an IP address assigned in order for this command to work.

Figure 3-13: A Telnet Connection

% telnet 192.0.1.88

3.3.1.4 Rlogin

Rlogin allows users to connect to a remote device as if they were on the local network. Rlogin is enabled by default.

To log into the MSS, type rlogin followed by the MSS IP address

Figure 3-14: An Rlogin Connection

% rlogin 192.0.1.88

3-7

Incoming Logins Getting Started

3.3.2 Serial Port Logins

Attach a terminal to one of the serial ports and press the Return key. The Local> prompt should be displayed. Proceed to the Configuration chapter to configure the unit using the command line interface.

If there was a problem during the boot process, pressing any key will display the Boot prompt. This prompt enables you to enter a special set of commands, called Boot Configuration Program (BCP) commands, which are discussed in Appendix B.

3.3.3 Remote Console Logins

You can configure the MSS via a Telnet connection to the remote console port, designated as port 7000. Connections to the console port cannot be disabled. This ensures that administrators will always be able to log into the port.

To connect to the remote console port, use the Telnet command followed by the MSS IP address and the remote console port number (7000). You will have to enter the login password. The default login password is access. For more information on the login password, see Login Passwords on page 3-2.

After you issue the appropriate password, you will see a Username> prompt. Enter a username to identify yourself as the current user.

Note: This username is arbitrary and used only for convenience. It is not

associated with authentication.
