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:
For a current list of supported PC card technologies, please check the Lantronix Web
site, www.lantronix.com.
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 or as the Server .
Model Overview
There are four MSS4 models, designated as -D, -S, -DFP, and -SFP. The models are differentiated by

IntroductionMSS Features
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 Help facility
is included.
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.
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 Web Browser
Login and Configuration on page 3-5.
Remote Configuration
The MSS can be logged into and remotely configured via a network login, a Telnet login to the remote
console port, EZWebCon, or a web browser connection to the MSS’s internal HTTP server.
Context-Sensitive Help
Context-sensitive on-line help is available at any time. You may type Help by itself for overall help,
Help <command> for help on a specific command, or a partial command line followed by a question
mark for help on what is appropriate at that point.
Note:
See the MSS Reference Manual for more information.
Reloadable Operating Software
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.
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.

IntroductionTCP/IP Support
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 easyto-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
SNMP
section of this guide

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, no parity, and XON/XOFF flow control.
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.

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.
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.
Supply power to the attached serial device(s), if necessary.

Ensure the MSS is working. There are a couple ways to check:
5
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.
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.
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.

1Power off the MSS by removing the plug from the outlet.
2Insert a supported 802.11 card into one of the PC card slots.
3Power 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.

InstallationInstalling PC Cards
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.
1Power off the MSS by unplugging its power cable.
2Insert a supported modem card into one of the PC card slots.
3If desired, insert another supported modem card into the other PC card slot.
4Power up the MSS by plugging its power cable into the outlet.

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
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, log in, and use the
command line interface to configure the unit.
Remote Console Logins: TCP/IP users can make a Telnet connection to the remote console port (port
7000).
MSS’s internal HTTP server via a standard web browser. After the initial
Consider the following points before you log in and configure the
Most configuration commands require privileged user status. Connecting a terminal to a serial port
MSS:
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
3-1).
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.
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.
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.
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.
Figure 3-1: Set Privileged Command

Getting StartedSystem Passwords
The privileged password can be changed with the Change Server Privpass command. Specify a new
password of up to six alphanumeric characters. Note that only the privileged user can change the privileged
password.

Note:
The Port and Server keywords are missing from the command names listed in the MSS
Reference Manual
. For example, Change Server Bootgateway is listed as Change
Bootgateway.
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.

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

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
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.
1Start EZWebCon. Instructions for installing, running, and using EZWebCon can be found on the
distribution CD-ROM.
2From the Action menu, select Assign IP Address.
3Enter or change the IP-related settings:
AFor Ethernet Address, enter the number that appears on the bottom label of your MSS.
BFor IP Address, enter the desired IP address to use for this MSS.
CFor 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.
Subnet Mask on page 4-2 for more information.
DFor Loadhost, enter the IP address of the loadhost where you intend to store your operating code
and SDK files (if used).
4Click OK.
5Wait for instructions from EZWebCon.
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
superuser privileges.
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. Windows NT
and Windows 2000 require Administrator rights to add an ARP entry.
Figure 3-7). This process typically requires
3-3
Getting StartedIP Address Configuration
Use the following commands to ARP the IP address to the MSS and make the MSS acknowledge the IP
assignment.
There should be replies from the IP address if the ARP command worked.
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 next 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 Server IPaddress command to make the address permanent.

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 Server
BOOTP Disabled and Change Server RARP Disabled commands. To enable DHCP, use the Change
Server DHCP Enabled command.
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 Server IPaddress
command.

Getting StartedIncoming Logins
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.
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 Server Incoming command and one of the
following parameters:
TelnetEnables incoming Telnet logins
NoneDisables all incoming logins
For security reasons, you may wish to disable incoming logins. Incoming logins for a port can be disabled
with the Change Port [Portlist] Access command (see Access Mode on page 4-8 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.
TCP/IP Logins
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.

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

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.
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.

% telnet 192.0.1.88
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

% rlogin 192.0.1.88
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.
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.
