Evolution OS® Operating System
The MatchPort AR embedded device server incorporates the Lantronix Evolution OS operating
system. Key features of the Evolution OS operating system include:
Built-in Web server for configuration and troubleshooting from Web-based browsers
CLI configurability
SNMP management
XML data transport and configurability
Really Simple Syndication (RSS) information feeds
2: Introduction
MatchPort® AR Embedded Device Server User Guide 18
Enterprise-grade security with SSL and SSH
Comprehensive troubleshooting tools
Additional Features
Modem Emulation
In modem emulation mode, the MatchPort AR device server can replace dial-up modems. The unit
accepts modem AT commands on the serial port, and then establishes a network connection to
the end device, leveraging network connections and bandwidth to eliminate dedicated modems
and phone lines.
Web-Based Configuration and Troubleshooting
Built upon Internet-based standards, the MatchPort AR embedded device serverenables you to
configure, manage, and troubleshoot through a browser-based interface accessible anytime from
anywhere. All configuration and troubleshooting options are launched from a web interface. You
can access all functions via a Web browser, for remote access. As a result, you decrease
downtime (using the troubleshooting tools) and implement configuration changes (using the
configuration tools).
Command-Line Interface (CLI)
Making the edge-to-enterprise vision a reality, the MatchPort AR embedded device server with
Evolution OS uses industry-standard tools for configuration, communication, and control. For
example, Evolution OS uses a Command Line Interface (CLI) whose syntax is very similar to that
used by data center equipment such as routers and hubs.
SNMP Management
The MatchPort AR supports full SNMP management, making it ideal for applications where device
management and monitoring are critical. These features allow networks with SNMP capabilities to
correctly diagnose and monitor MatchPort AR device servers.
XML-Based Architecture and Device Control
XML is a fundamental building block for the future growth of M2M networks. The MatchPort AR
embedded device server supports XML-based configuration setup records that make device
configuration transparent to users and administrators. The XML is easily editable with a standard
text or XML editor.
Really Simple Syndication (RSS)
The MatchPort AR device server supports Really Simple Syndication (RSS) for streaming and
managing on-line content. RSS feeds all the configuration changes that occur on the device. An
RSS aggregator then reads (polls) the feed. More powerful than simple email alerts, RSS uses
XML as an underlying Web page transport and adds intelligence to the networked device, while
not taxing already overloaded email systems.
Enterprise-Grade Security
Evolution OS provides the MatchPort AR embedded device server the highest level of networking
security possible. This ‘data center grade’ protection ensures that each device on the M2M
2: Introduction
MatchPort® AR Embedded Device Server User Guide 19
network carries the same level of security as traditional IT networking equipment in the corporate
data center.
With built-in SSH and SSL, secure communications can be established between the serial ports
and the remote end device or application. By protecting the privacy of serial data transmitted
across public networks, users can maintain their existing investment in serial technology, while
taking advantage of the highest data-protection levels possible.
SSH and SSL are able to do the following:
Verify the data received came from the proper source
Validate that the data transferred from the source over the network has not changed when it
arrives at its destination (shared secret and hashing)
Encrypt data to protect it from prying eyes and nefarious individuals
Provide the ability to run popular M2M protocols over a secure SSH or SSL connection
In addition to keeping data safe and accessible, the MatchPort AR device server has robust
defenses to hostile Internet attacks such as denial of service (DoS), which can be used to take
down the network. Moreover, the MatchPort AR embedded device server cannot be used to bring
down other devices on the network.
You can use the MatchPort AR device server with the Lantronix Secure Com Port Redirector
(SCPR) to encrypt COM port-based communications between PCs and virtually any electronic
device. SCPR is a Windows application that creates a secure communications path over a
network between the computer and serial-based devices that are traditionally controlled via a
COM port. With SCPR installed at each computer, computers that were formerly “hard-wired” by
serial cabling for security purposes or to accommodate applications that only understood serial
data can instead communicate over an Ethernet network or the Internet.
Terminal Server/Device Management
Remote offices can have routers, PBXs, servers and other networking equipment that require
remote management from the corporate facility. The MatchPort AR embedded device server
easily attaches to the serial ports on a server, Private Branch Exchange (PBX), or other
networking equipment to deliver central, remote monitoring and management capability.
With the menu system on the MatchPort device, connections to the console ports of the attached
devices as well as network hosts, such as Unix servers or another MatchPort unit, can easily be
picked from a user-defined menu. This allows console ports across multiple devices to be
accessed from one MatchPort.
Troubleshooting Capabilities
The MatchPort AR embedded device server offers a comprehensive diagnostic toolset that lets
you troubleshoot problems quickly and easily. Available from the Web Manager, CLI, and XML
interfaces, the diagnostic tools let you:
View critical hardware, memory, MIB-II, buffer pool, and IP socket information.
Perform ping and traceroute operations.
Conduct forward or backup DNS lookup operations.
View all processes currently running on the MatchPort AR device server, including CPU
utilization and total stack space available.

MatchPort® AR Embedded Device Server User Guide 20
Configuration Methods
After installation, the MatchPort AR embedded device server requires configuration. For the unit to
operate correctly on a network, it must have a unique IP address on the network. There are four
basic methods for logging into the MatchPort AR and assigning IP addresses and other
configurable settings:
DeviceInstaller: Configure the IP address and related settings and view current settings on the
using a Graphical User Interface (GUI) on a PC attached to a network. See Chapter 3: Using
DeviceInstaller.
Web Manager: Through a web browser, configure the MatchPort AR settings using the Lantronix
Web Manager. See Configuration Using Web Manager (on page 24).
Command Mode: There are two methods for accessing Command Mode (CLI): making a Telnet
connection or connecting a terminal (or a PC running a terminal emulation program) to the unit’s
serial port. (See the MatchPort AR Embedded Device Server Command Reference for instructions
and available commands.)
XML: The MatchPort AR embedded device server supports XML-based configuration and setup
records that make device configuration transparent to users and administrators. XML is easily
editable with a standard text or XML editor. (See the MatchPort AR Embedded Device Server
Command Reference for instructions and commands.)
Addresses and Port Numbers
Hardware Address
The hardware address is also referred to as the Ethernet address or MAC address. The first three
bytes of the Ethernet address are fixed and read 00-20-4A, identifying the unit as a Lantronix
product. The fourth, fifth, and sixth bytes are unique numbers assigned to each unit.
Figure 2-1 Sample Hardware Address
00-20-4A-14-01-18 or 00:20:4A:14:01:18
IP Address
Every device connected to an IP network must have a unique IP address. This address references
the specific unit.
Port Numbers
Every TCP connection and every UDP datagram is defined by a destination and source IP
address, and a destination and source port number. For example, a Telnet server commonly uses
port number 23.
The following is a list of the default server port numbers running on the MatchPort AR embedded
device server:
-TCP Port 22: SSH Server (Command Mode configuration)
-TCP Port 23: Telnet Server (Command Mode configuration)
-TCP Port 80: HTTP (Web Manager configuration)
-TCP Port 443: HTTPS (Web Manager configuration)

3. Click Submit to save changes. Some changes to the following settings require a reboot for the
changes to take effect:
-BOOTP Client
-DHCP Client
-IP Address
-DHCP Client ID
Note: If DHCP or BOOTP fails, AutoIP intervenes and assigns an address.A new DHCP
negotiation is attempted every 5 minutes to obtain a new IP address. When the DHCP is
enabled, any configured static IP address is ignored.
DHCP Client Select On or Off. At boot up, the device will attempt to lease an IP address from a
DHCP server and maintain the lease at regular intervals.
Note: Overrides BOOTP, the configured IP address, network mask, gateway,
hostname, and domain.
IP Address Enter the device static IP address.
You may enter it alone, in CIDR format, or with an explicit mask.
The IP address consists of four octets separated by a period and is used if BOOTP and
DHCP are both set to Off. Changing this value requires you to reboot the device.
Note: When DHCP is enabled, the device tries to obtain an IP address from DHCP. If
it cannot, the device uses an AutoIP address in the range of 169.254.xxx.xxx.
Default Gateway Enter the IP address of the router for this network. Or, clear the field (appears as
<None>). This address is only used for static IP address configuration.
Hostname Enter the device hostname. It must begin with a letter, continue with a sequence of
letters, numbers, and/or hyphens, and end with a letter or number.
Domain Enter the device domain name.
DHCP Client ID Enter the ID if the DHCP server uses a DHCP ID. The DHCP server’s lease table
shows IP addresses and MAC addresses for devices. The lease table shows the Client
ID, in hexadecimal notation, instead of the device MAC address.
Note: "Binary" entry mode allows a mixed mode of text and special characters in
brackets For example, "abcd<ctrl>A" would be entered "abcd[0x01]".
Primary DNS IP address of the primary name server. This entry is required if you choose to configure
DNS (Domain Name Server) servers.
Secondary DNS IP address of the secondary name server.
MTU When DHCP is enabled, the MTU size is (usually) provided with the IP address. When
not provided by the DHCP server, or using a static configuration, this value is used. The
MTU size can be from 576 to 1500 bytes.

Tunnel Settings
Note: The number of lines and tunnels available for viewing and configuration differ
between Lantronix products. For example, an XPort Pro and EDS1100 support only one
line while other device networking products (such as EDS2100, EDS4100, MatchPort AR,
XPort AR, EDS8/16PS and EDS8/16/32PR devices) provide additional lines and tunnels.
Tunneling allows serial devices to communicate over a network, without “being aware” of the
devices which establish the network connection between them.Tunneling parameters are
configured using the Web Manager or Command Mode Tunnel Menu. See Configuration Using
Web Manager (on page 24) or the MatchPort AR Command Reference for the full list of
commands.
The MatchPort AR embedded device server supports two tunneling connections simultaneously
per serial port. One of these connections is Connect Mode; the other connection is Accept Mode.
The connections on one serial port are separate from those on another serial port.
Connect Mode: the MatchPort AR embedded device server actively makes a connection.
The receiving node on the network must listen for the Connect Mode’s connection. Connect
Mode is disabled by default.
Accept Mode: the MatchPort AR device listens for a connection. A node on the network
initiates the connection. Accept Mode is enabled by default.
Disconnect Mode: this mode defines how an open connection stops the forwarding of data.
The specific parameters to stop the connection are configurable. Once the MatchPort AR
Disconnect Mode observes the defined event occur, it will disconnect both Accept Mode and
Connect Mode connections on that port.
Serial String Enter the serial string characters. Select a string type.
Text = string of bytes that must be read on the Serial Line during boot time to
enable Command Mode. It may contain a time element in x milliseconds, in
the format {x}, to specify a required delay.
Binary = string of characters representing byte values where each
hexadecimal byte value starts with \0x and each decimal byte value starts
with \.
Echo Serial String Select Yes to enable echoing of the serial string at boot-up.
CP Group Enter the name and decimal value of the CP Group. When the value matches
the current value of the group, Command Mode is enabled on the Serial Line.
Signon Message Enter the boot-up signon message. Select a string type.
Text = string of bytes sent on the serial line during boot time.
Binary = one or more byte values separated by commas. Each byte value
may be decimal or hexadecimal. Start hexadecimal values with 0x.
Note: This string will be output on the serial port at boot, regardless of whether
command mode is enabled or not.

Tunnel – Packing Mode
Packing Mode takes data from the serial port, packs it together, and sends it over the network.
Packing can be configured based on threshold (size in bytes, timeout (milliseconds), or a single
character.
Size is set by modifying the threshold field. When the number of bytes reaches the threshold, a
packet is sent immediately.
The timeout field is used to force a packet to be sent after a maximum time. The packet is sent
even if the threshold value is not reached.
When Send Character is configured, a single printable character or control character read on the
Serial Line forces the packet to be sent immediately. There is an optional trailing character
parameter which can be specified. It can be a single printable character or a control character.
To configure the Packing Mode for a specific tunnel:
1. Select Tunnel on the menu bar, if you are not already in the Tunnel web page.
2. Select a tunnel number at the top of the page.

Tunnel – Accept Mode
Controls how a specific tunnel number behaves when a connection attempt originates from the
network. In Accept Mode, the MatchPort AR embedded device server waits for a connection from
the network. The configurable local port is the port the remote device connects to for this
connection. There is no remote port or address. The default local port is 10001 for serial port 1 and
increases sequentially for each additional serial port, if supported.
Accept Mode supports the following protocols:
-SSH (the MatchPort AR device is the server in Accept Mode). When using this protocol,
the SSH server host keys and at least one SSH authorized user must be configured.
-SSL
-TCP
-AES encryption over TCP
-Telnet (the MatchPort AR embedded device server supports IAC codes. It drops the IAC
codes when Telnetting and does not forward them to the serial port).

Tunnel – Connect Mode
Connect Mode defines how the device makes an outgoing connection through a specific tunnel.
When enabled, Connect Mode is always on and attempting a network connection if the connection
mode condition warrants it. For Connect Mode to function, it must:
Be enabled
Have a remote host configured
Have a remote port configured
Enter the remote host address as an IP address or DNS name. The MatchPort AR device will
make a connection only if it can resolve the address. For DNS names, the MatchPort AR
embedded device server will re-evaluate the address after being established for 4 hours. If re-
evaluation results in a different address, it will close the connection.
Connect Mode supports the following protocols:
TCP
AES encryption over TCP and UDP
When setting AES encryption, both the encrypt key and the decrypt key must be specified.
The encrypt key is used for data sent out. The decrypt key is used for receiving data. Both of
the keys may be set to the same value.
SSH
To configure SSH, the SSH client username must be configured. In Connect Mode, the AR
unit is the SSH client. Ensure the MatchPort AR SSH client username is configured on the
remote SSH server before using it with the MatchPort AR embedded device server.
SSL
UDP
Is only available in Connect Mode because it is a connectionless protocol. For Connect Mode
using UDP, the MatchPort AR unit accepts packets from any device on the network. It will
send packets to the last device that sent it packets.
Telnet
Note: The Local Port in Connect Mode is independent of the port configured in Accept
Mode.
There are six different connect modes:
Disable
No connection is attempted.
Always
A connection is always attempted.
Any Character
A connection is attempted if it detects any
character from the serial port.
Start Character
A connection is attempted if it detects a specific and configurable character from the serial
port.
Note: While in the “Any Character” or “Start
Character” connection modes, the
MatchPort AR embedded device server
waits and retries the connection if the
connection cannot be made. Once it makes
a connection and then disconnects, it will
not reconnect until it sees another character
or the start character again (depending on
the configured setting).

5. Click Submit. The host is configured.Repeat these steps to configure additional hosts as
necessary. MatchPort AR supports configuration of up to sixteen hosts.
Reconnect Timer Enter the reconnect time in milliseconds. The device attempts to reconnect after
this amount of time after failing a connection or exiting an existing connection.
This behavior depends upon the Disconnect Mode.
Note:
When you configure Tunnel - Connect Mode, you can specify a number
of milliseconds to attempt to reconnect after a dropped connection has
occurred. The default is 1500 milliseconds.
The Reconnect Timer only applies if a Disconnect Mode is configured.
With a Disconnect Mode set, the device server maintains a connection
until the disconnect mode condition is met (at which time the device server
closes the connection). If the tunnel is dropped due to conditions beyond
the device server, the device server attempts to re-establish a failed
connection when the specified reconnect interval reaches its limit.
Any network-side disconnect is considered an error and a reconnect is
attempted without regard to the Connect Mode settings. Simultaneous
Connect Mode connections require some Disconnect Mode
configurations or the connections will never terminate. See Tunnel –
Disconnect Mode on page 50 for more information about the parameters.
If Disconnect Mode is disabled and the network connection is dropped,
then the re-establishment of a tunnel connection is governed by the
configured Connect Mode settings.

appears. Host Mode controls
how multiple hosts will be
accessed. For MatchPort AR
embedded device server, the
Connect Mode supports up to
sixteen Hosts. Hosts may be
accessed sequentially or
simultaneously:
Sequential – Sequential
host lists establish a
prioritized list of tunnels.
The host specified as Host
1 will be attempted first. If
that fails, it will proceed to
Host 2, 3, etc, in the order
they are specified. When a
connection drops, the cycle
starts again with Host 1 and
proceeds in order.
Establishing the host order
is accomplished with host
list promotion (see Host List
Promotion on page 50).
Sequential is the default
Host Mode.
Simultaneous – A tunnel will connect to all hosts accepting a connection. Connections occur
at the same time to all listed hosts. The device can support a maximum of 64 total aggregate
connections.

modem. For commands that are valid but not applicable to the MatchPort AR embedded device
server, an “OK” message is sent (but the command is silently ignored).
The MatchPort AR unit attempts to make a Command Mode connection as per the IP/DNS/port
numbers defined in Connect Mode. It is possible to override the remote address, as well as the
remote port number.
The following table lists and describes the available commands.

MatchPort® AR Embedded Device Server User Guide 53
For commands that can take address information (ATD, ATDT, ATDP), the destination address
can be specified by entering the IP Address, or entering the IP Address and port number. For
example, <ipaddress>:<port>. The port number cannot be entered on its own.
For ATDT and ATDP commands less than 255 characters, the MatchPort AR replaces the last
segment of the IP address with the configured Connect Mode remote station address. It is possible
to use the last two segments also, if they are under 255 characters. For example, if the address is
100.255.15.5, entering ATDT 16.6 results in 100.255.16.6.
When using ATDT and ATDP, enter 0.0.0.0 to switch to the Command Line Interface (CLI). Once
the CLI is exited by using the CLI exit command, the MatchPort AR embedded device server
reverts to modem emulation mode. By default, the +++ characters are not passed through the
connection. Turn on this capability using the modem echo pluses command.
To configure modem emulation for a specific tunnel:
1. Select Tunnel on the menu bar, if you are not already in the Tunnel web page.
2. Select a tunnel number at the top of the page.
3. Select Modem Emulation. The Modem Emulation page for the specific tunnel appears.

8: Configurable Pin Manager
The Configurable Pin Manager is responsible for assignment and control of the configurable pins
(CPs) available on the MatchPort AR embedded device server. There are seven configurable pins
on the MatchPort AR unit.
You can configure the CPs by making them part of a group. A CP Group may consist of one or
more CPs. This increases flexibility when incorporating the MatchPort AR embedded device
server into another system.
This chapter contains the following sections:
Overview
CPM: CP (Configurable Pins)
CPM: Groups
Overview
Each CP is associated with an external hardware pin. CPs can be configured and used as digital
inputs or outputs.
When used as input, device functionality can be triggered based on the state of a CP. For
example, an email can be sent when a CP is asserted to a preconfigured level. When used as an
output, logic levels of the CP can be manipulated when a preconfigured event occurs on the
device server, such as when a tunnel connection is accepted.
CPs are configured and manipulated within a group. Each group is named and is referenced in the
feature that is triggering a CP or being triggered by a CP. Sophisticated use of CPs can be
accommodated by adding more than one CP into a group.
Default Groups
MatchPort AR unit has several predefined CP groups used to assign a CP to a needed function.
For instance, when working with an RS485 driver that requires a signal to be asserted when in
half–duplex mode, the CP that is driving that signal (chosen by the engineer designing the circuit)
is added to the default group named Line1_RS485_HDpx. The MatchPort AR device asserts the
CP at the correct time via the default group.
Custom Groups
The email, tunneling, and CLI features can interact with CPs. This is accomplished by creating a
custom group and adding CPs of your choice into that group. Once a CP group is created and
populated with one or more CPs, actions can be triggered when the CPs match a specified value.
CPs can be placed in any bit position within a group, allowing for sophisticated use of the available
CPs.
CPM: CP (Configurable Pins)
Each CP is associated with an external hardware pin. CPs can trigger an outside event, like
sending an email message or starting Command Mode on a serial Line.

The CPM web page is used to experimentally configure the state of the CPs. CPs can be changed
to be a digital input or a digital output, and whether it is asserted high or low. Changes made on
this page do not -persist through a reboot.
Rules for configuring a CP are as follows. A CP:
Can be in any number of groups.
Can be only in one active group. Two groups with the same CP cannot be enabled at the
same time.

Point-to-Point (PPP) Settings
Point-to-Point Protocol establishes a direct connection between two nodes. It defines a method for
data link connectivity between devices using physical layers (such as serial lines).
The MatchPort AR device server supports two types of PPP authentication: Password
Authentication Protocol (PAP) and Challenge Handshake Authentication Protocol (CHAP). Both of
these authentication methods require the configuration of a username and password. The
MatchPort AR embedded device server also supports the authentication scheme of “None” when
no authentication is required during link negotation.
PAP authentication offers a straightforward method for the peer to determine its identity. Upon the
link establishment, the user ID and password are repeatedly sent to the authenticator until it is
acknowledged or the connection is terminated. However, PAP is not a strong authentication
process. There is no protection against trial-and-error attacks. The peer is responsible for the
frequency of the authentication communication attempts.
CHAP is a more secure method than PAP. It works by sending a challenge message to the
connection requestor. Using a one-way hash function, the requestor responds with its value. If the
value matches the server’s own calculations, authentication is provided. Otherwise, the connection
is terminated.
Note: RFC1334 defines both CHAP and PAP.
The MatchPort AR embedded device server also supports authentication scheme of “None” when
no authentication is required during link negotiation.
Since the MatchPort AR unit does not support Network Address and Port Translation (NAPT),
static routing table entries must be added to the serial-side and network-side devices (both of
which are external devices).
Use the MatchPort AR Web Manager or CLI to configure a network link using PPP over a serial
line. Turn off Connect Mode, Accept Mode, and Command mode before enabling PPP. The
device acts as the server side of the PPP link; it can require authentication and assign an IP
address to the peer. Upon PPP configuration, IP packets are routed between Ethernet and PPP
interfaces.
Note: The MatchPort AR embedded device server does not perform network address
translation (NAT) between the serial-side network interface and the Ethernet/WLAN
network interface. Therefore, to pass packets through the unit, a static route must be
configured on both the PPP Peer device and the remote device it wishes to communicate

with. The static route in the PPP Peer device must use the PPP Local IP Address as its
gateway, and the static route in the remote device must use the network interface IP
Address of the MatchPort AR embedded device server as its gateway.
The following section describes the steps to configure PPP 1 (PPP on serial line 1); these steps
also apply to any line instance of the device. Since the MatchPort AR unit does not support NAPT
(Network Address and Port Translation), static routing table entries must be added to both the
serial-side and network-side devices (both of which are external to the MatchPort AR embedded
device server).

The MatchPort AR embedded device server supports Secure Shell (SSH) and Secure Sockets
Layer (SSL). SSH is a network protocol for securely accessing a remote device. SSH provides a
secure, encrypted communication channel between two hosts over a network. It provides
authentication and message integrity services.
Secure Sockets Layer (SSL) is a protocol that manages data transmission security over the
Internet. It uses digital certificates for authentication and cryptography against eavesdropping and
tampering. It provides encryption and message integrity services. SSL is widely used for secure
communication to a web server. SSL uses certificates and private keys.
Note: The MatchPort AR device server supports SSLv3 and its successors, TLS1.0 and
TLS1.1. An incoming SSlv2 connection attempt is answered with an SSlv3 response. If
the initiator also supports SSLv3, SSLv3 handles the rest of the connection.

SSH Settings
SSH is a network protocol for securely accessing a remote device over an encrypted channel. This
protocol manages the security of internet data transmission between two hosts over a network by
providing encryption, authentication, and message integrity services.
Two instances require configuration: when the MatchPort AR unit is the SSH server and when it is
an SSH client. The SSH server is used by the CLI (Command Mode) and for tunneling in Accept
Mode. The SSH client is for tunneling in Connect Mode.
To configure the MatchPort AR embedded device server as an SSH server, there are two
requirements:
Defined Host Keys: both private and public keys are required. These keys are used for the
Diffie-Hellman key exchange (used for the underlying encryption protocol).
Defined Users: these users are permitted to connect to the MatchPort AR SSH server.

SSH Server Host Keys
SSH Host Keys can be obtained in a few different ways:
Uploading keys via PUTTY or other tools which generate RFC4716 format keys.
Creating keys through the device.
The steps for creating or uploading keys is described below.
To upload SSH server host keys generated from PuTTY:
1. Create the keys with puttygen.exe. The keys are in PuTTY format.
2. Use puttygen.exe again to convert the private key to Open SSH format as follows:
a. Import the private key using "Conversions…Import key."
b. Create a new file using "Conversions…Export OpenSSH key."
3. Use ssh-keygen to convert the public key to OpenSSH format.
ssh-keygen -i -f putty_file > openssh_file
4. Select SSH on the menu bar and SSH Server: Host Keys at the top of the page. The SSH
Server Host Keys page appears.

SSH client known users are used by all applications that play the role of an SSH client, specifically
tunneling in Connect Mode. At the very least, a password or key pair must be configured for a
user. The keys for public key authentication can be created elsewhere and uploaded to the device
or automatically generated on the device. If uploading existing keys, be sure the private key will
not be compromised in transit. This implies the data is uploaded over some kind of secure private
network.
Note: If you are providing a key by uploading a file, make sure that the key is not
password protected.
To configure the SSH client users:
1. Select SSH on the menu bar and then SSH Client Users at the top of the page. The SSH
Client: Users page appears.

SSH Client: Users
Settings
Description
Username Enter the name that the device uses to connect to a SSH server.
Password Enter the password associated with the username.
Remote Command Enter the command that can be executed remotely. Default is shell, which tells the
SSH server to execute a remote shell upon connection. This command can be
changed to anything the remote host can perform.
Private Key Enter the name of the existing private key you want to use with this SSH client user.
You can either enter the path and name of the key, or use the Browse button to
select the key.
Public Key Enter the path and name of the existing public key you want to use with this SSH
client user or use the Browse button to select the key.
Note: If the user public key is known on the remote SSH server, the SSH server
does not require a password. The Remote Command is provided to the SSH server
upon connection. It specifies the application to execute upon connection. The default
is a command shell.
Note: Configuring the SSH client’s known hosts is optional. It prevents Man-In-The-
Middle (MITM) attacks
Key Type Select the key type to be used. Choices are:
RSA = use this key with the SSH1 and SSH2 protocols.
DSA = use this key with the SSH2 protocol.
Create New Keys
Username Enter the name of the user associated with the new key.
Key Type Select the key type to be used for the new key. Choices are:
RSA = use this key with the SSH1 and SSH2 protocols.
DSA = use this key with the SSH2 protocol.
Bit Size Select the bit length of the new key:
512
768
1024
Using a larger Bit Size takes more time to generate the key. Approximate times are:
10 seconds for a 512 bit RSA Key
15 seconds for a 768 bit RSA Key
1 minute for a 1024 bit RSA key
30 seconds for a 512 bit DSA key
1 minute for a 768 bit DSA key
2 minutes for a 1024 bit DSA key
Note: Some SSH clients require RSA host keys to be at least 1024 bits long. This
device generates keys up to 1024 bits long. It can work with larger keys (up to 2048
bit) if they are imported or otherwise created.

SSL Settings
Secure Sockets Layer (SSL) is a protocol for managing the security of data transmission over the
Internet. It provides encryption, authentication, and message integrity services. SSL is widely used
for secure communication to a web server.
Certificate/Private key combinations can be obtained from an external Certificate Authority (CA)
and downloaded into the unit. Self-signed certificates with associated private key can be
generated by the device server itself.
For more information regarding Certificates and how to obtain them, see SSL Certificates and
Private Keys (on page 94).
SSL uses digital certificates for authentication and cryptography against eavesdropping and
tampering. Sometimes only the server is authenticated; sometimes both server and client are
authenticated. The AR embedded device server can be server and/or client, depending on the
application. Public key encryption systems exchange information and keys and set up the
encrypted tunnel.
Efficient symmetric encryption methods encrypt the data going through the tunnel after it is
established. Hashing provides tamper detection.
Applications that can make use of SSL are Tunneling, Secure Web Server, and WLAN interface.
The MatchPort AR unit supports SSlv3 and its successors, TLS1.0 and TLS1.1.
Note: An incoming SSlv2 connection attempt is answered with an SSlv3 response. If the
initiator also supports SSLv3, SSLv3 handles the rest of the connection.
SSL Cipher Suites
The SSL standard defines only certain combinations of certificate type, key exchange method,
symmetric encryption, and hash method. Such a combination is called a cipher suite. Supported
cipher suites include the following:
Whichever side is acting as server decides which cipher suite to use for a connection. It is usually
the strongest common denominator of the cipher suite lists supported by both sides.
Table 10-13 Supported Cipher Suites

DSA DHE 3DES SHA1
RSA RSA 128 bits AES SHA1

MatchPort® AR Embedded Device Server User Guide 94
SSL Certificates
The goal of a certificate is to authenticate its sender. It is analogous to a paper document that
contains personal identification information and is signed by an authority, for example a notary or
government agency.
The principles of Security Certificate require that in order to sign other certificates, the authority
uses a private key. The published authority certificate contains the matching public key that allows
another to verify the signature but not recreate it.
The authority’s certificate can be signed by itself, resulting in a self-signed or trusted-root
certificate, or by another (higher) authority, resulting in an intermediate authority certificate. You
can build up a chain of intermediate authority certificates, and the last certification will always be a
trusted-root certificate.
An authority that signs other certificates is also called a Certificate Authority (CA). The last in line is
then the root-CA. VeriSign is a famous example of such a root-CA. Its certificate is often built into
web browsers to allow verifying the identity of website servers, which need to have certificates
signed by VeriSign or another public CA. Since obtaining a certificate signed by a CA that is
managed by another company can be expensive, it is possible to have your own CA. Tools exist to
generate self-signed CA certificates or to sign other certificates.
A certificate request is a certificate that has not been signed and only contains the identifying
information. Signing it makes it a certificate. A certificate is also used to sign any message
transmitted to the peer to identify the originator and prevent tampering while transported.
When using HTTPS and/or SSL Tunneling in Accept mode, the MatchPort AR unit needs a
personal certificate with a matching private key to identify itself and sign its messages. When using
SSL Tunneling in Connect mode, the MatchPort AR embedded device server needs the authority
certificate that can authenticate users with which it wishes to communicate.
SSL RSA or DSA
As mentioned above, the certificates contain a public key. Different key exchange methods require
different public keys and thus different styles of certificate. The MatchPort AR embedded device
server supports key exchange methods that require a RSA-style certificate and key exchange
methods that require a DSA-style certificate. If only one of these certificates is stored in the
MatchPort AR unit, only those key exchange methods that can work with that style certificate are
enabled. RSA is sufficient in most cases.
SSL Certificates and Private Keys
You can obtain a certificate by completing a certificate request and sending it to a certificate
authority that will create a certificate/key combo, usually for a fee, or you can generate your own. A
few utilities exist to generate self-signed certificates or sign certificate requests. The MatchPort AR
embedded device server also has the ability to generate its own self-signed certificate/key combo.
You can use XML to export the certificate in PEM format, but you cannot export the key. Hence the
internal certificate generator can only be used for certificates that are to identify that particular
MatchPort AR unit.
Certificates and private keys can be stored in several file formats. Best known are PKCS12, DER
and PEM. Certificate and key can be in the same file or in separate files. The key can be encrypted
with a password or not. The MatchPort AR embedded device server currently only accepts
separate PEM files. The key needs to be unencrypted.

MatchPort® AR Embedded Device Server User Guide 95
SSL Utilities
Several utilities exist to convert between the formats.
OpenSSL
Open source is a set of SSL related command line utilities. It can act as server or client. It can
generate or sign certificate requests. It can convert all kinds of formats. Executables are available
for Linux and Windows. To generate a self-signed RSA certificate/key combo use the following
commands in the order shown:
openssl req –x509 –nodes –days 365 –newkey rsa:1024 –keyout
mp_key.pem –out mp_cert.pem
Note: Signing other certificate requests is also possible with OpenSSL. See
www.openssl.org or www.madboa.com/geek/openssl for more information.

11: Modbus
Modbus ASCII/RTU based serial slave devices can be connected via the ethernet through an
existing Modbus TCP/IP network. Any device having access to a given Modbus implementation
will be able to perform full range of operations that the implementation supports. Modbus/TCP
uses a reserved TCP port of 502 and include a single byte function code (1=255) preceded by a 6
byte header:
Table 11-1 6 Byte Header of Modbus Application Protocol
CP Control via Modbus
Default groups are mapped to Modbus registers. CPs added to groups will result in the CP being
read and written based on the reading or writing to the register which maps to that CP group.
Default Modbus group names include:
Modbus_Ctl_In
Modbus_Ctl_Out
Note: Refer to Chapter 8: CPM: Groups on page 62 for instructions on adding a CP to a
Group.
When the Modbus slave address is set to 0xFF, the message is addressed to the internal default
groups and thus processed by the MatchPort AR embedded device server. The Modbus 'local
slave' supported functions are listed in the table below.

3. Modify the following settings:
Table 12-5 TCP Protocol Settings
Protocol Stack
TCP Settings
Description
Send RSTs Click Enabled to send RSTs or Disabled to stop sending RSTs. TCP contains six
control bits, with one or more defined in each packet. RST is one of the control bits.
The RST bit is responsible for telling the receiving TCP stack to end a connection
immediately.
Note: Setting the RSTs may pose a security risk.
Ack Limit Enter a number to limit how many packets get received before an ACK gets forced.
If there is a large amount of data to acknowledge, an ACK gets forced. If the sender
TCP implementation waits for an ACK before sending more data even though the
window is open, setting the Ack Limit to 1 packet improves performance by forcing
immediate acknowledgements.
Send Data The Send Data selection governs when data may be sent into the network. The
Standard implementation waits for an ACK before sending a packet less than the
maximum length. Select Expedited to send data whenever the window allows it.

IP Time to Live This value typically fills the Time To Live in the IP header. SNMP refers to this
value as "ipDefaultTTL".
Enter the number of hops to be transmitted before the packet is discarded.
Multicast Time to Live This value fills the Time To Live in any multicast IP header. Normally this value
will be one so the packet will be blocked at the first router. It is the number of
hops allowed before a Multicast packet is discarded.
Enter the value to be greater than one to intentionally propagate multicast
packets to additional routers.

XML Settings
MatchPort AR embedded device server allows for the configuration of devices by using XML
configuration records (XCRs). You can export an existing configuration for use on other devices or
import a saved configuration file.
On the XML: Export Configuration web page, you can export the current system configuration in
XML format. The generated XML file can be imported later to restore a configuration. It can also be
modified and imported to update the configuration on this MatchPort AR unit or another. The XML
data can be exported to the browser window or to a file on the file system.
By default, all groups are selected except those pertaining to the network configuration. This is so
that if you later import the entire XML configuration, it will not break your network connectivity. You
may select or clear the checkbox for any group.
In the XML: Import System Configuration Page you can import a system configuration from an
XML file. The XML data can be imported from a file on the file system or uploaded using HTTP.
The groups to import can be specified by toggling the respective group item or entering a filter
string. When toggling a group item, all instances of that group will be imported. The filter string can
be used to import specific instances of a group. The text format of this string is:
<g>:<i>;<g>:<i>;...
For example, if you only wanted to import the line 1 setting from an XCR, use a filter string of
line:1.
Each group name <g> is followed by a colon and the instance value <i>. Each <g> :<i> value is
separated with a semicolon. If a group has no instance, specify the group name <g> only.
The number of lines available for importing and exporting differ between Lantronix products. The
screenshots in this chapter represent one line, as available, for example, on an XPort Pro
embedded networking module and EDS1100. However, other device networking products (such
as EDS2100, EDS4100, XPort AR, MatchPort AR embedded networking modules, EDS8/16PS
and EDS8/16/32PR) support additional lines.

14: Security in Detail
Public Key Infrastructure
Public key infrastructure (PKI) is based on an encryption technique that uses two keys: a public
key and private key. Public keys can be used to encrypt messages which can only be decrypted
using the private key. This technique is referred to as asymmetric encryption, as opposed to
symmetric encryption, in which a single secret key is used by both parties.
TLS (SSL)
Transport Layer Security (TLS) and its predecessor, Secure Sockets Layer (SSL), use asymmetric
encryption for authentication. In some scenarios, only a server needs to be authenticated, in
others both client and server authenticate each other. Once authentication is established, clients
and servers use asymmetric encryption to exchange a secret key. Communication then proceeds
with symmetric encryption, using this key.
SSH and some wireless authentication methods on the MatchPort AR embedded device server
make use of SSL. The MatchPort AR unit supports SSLv2, SSlv3, and TLS1.0.
TLS/SSL application hosts use separate digital certificates as a basis for authentication in both
directions: to prove their own identity to the other party, and to verify the identity of the other party.
In proving its own authenticity, the MatchPort AR embedded device server will use its own
"personal" certificate. In verifying the authenticity of the other party, the MatchPort AR unit will use
a "trusted authority" certificate.
Digital Certificates
The goal of a certificate is to authenticate its sender. It is analogous to a paper document that
contains personal identification information and is signed by an authority, for example a notary or
government agency. With digital certificates, a cryptographic key is used to create a unique digital
signature.
Trusted Authorities
A private key is used by a trusted certificate authority (CA) to create a unique digital signature.
Along with this private key is a certificate of authority, containing a matching public key that can be
used to verify the authority's signature but not re-create it.
A chain of signed certificates, anchored by a root CA, can be used to establish a sender's
authenticity. Each link in the chain is certified by a signed certificate from the previous link, with
the exception of the root CA. This way, trust is transferred along the chain, from the root CA
through any number of intermediate authorities, ultimately to the agent that needs to prove its
authenticity.
www ogenssl org or www madboa com/geeklogenssl
14: Security in Detail
MatchPort® AR Embedded Device Server User Guide 138
Obtaining Certificates
Signed certificates are typically obtained from well-known CAs, such as VeriSign. This is done by
submitting a certificate request for a CA, typically for a fee. The CA will sign the certificate request,
producing a certificate/key combo: the certificate contains the identity of the owner and the public
key, and the private key is available separately for use by the owner.
As an alternative to acquiring a signed certificate from a CA, you can act as your own CA and
create self-signed certificates. This is often done for testing scenarios, and sometimes for closed
environments where the expense of a CA-signed root certificate is not necessary.
Self-Signed Certificates
A few utilities exist to generate self-signed certificates or sign certificate requests. The MatchPort
AR embedded device server also has the ability to generate its own self-signed certificate/key
combo. You can use XML to export the certificate in PEM format, but you cannot export the key.
Hence the internal certificate generator can only be used for certificates that are to identify that
particular MatchPort AR unit.
Certificate Formats
Certificates and private keys can be stored in several file formats. The best known formats are
PKCS12, DER and PEM. Certificate and key can be in the same file or in separate files.
Additionally, the key can either be encrypted with a password or left in the clear. However, the
MatchPort AR embedded device server currently only accepts separate PEM files, with the key
unencrypted.
Several utilities exist to convert between the formats.
OpenSSL
OpenSSL is a widely used open source set of SSL related command line utilities. It can act as
server or client. It can also generate or sign certificate requests, and can convert from and to
several different of formats.
OpenSSL is available in binary form for Linux and Windows.
To generate a self-signed RSA certificate/key combo:
openssl req -x509 -nodes -days 365 -newkey rsa:1024 -keyout mp_key.pem -
out mp_cert.pem
See www.openssl.org or www.madboa.com/geek/openssl for more information.
Note: Signing other certificate requests is also possible with OpenSSL but the details of
this process are outside the scope of this document.

15: Branding the MatchPort AR Unit
This chapter describes how to brand your MatchPort AR embedded device server by using Web
Manager and Command Line Interface (CLI). It contains the following sections on customization:
Web Manager Customization
Short and Long Name Customization
Web Manager Customization
Customize the Web Manager’s appearance by modifying index.html and style.css. The style
(fonts, colors, and spacing) of the Web Manager is controlled with style.css and the text and
graphics are controlled with index.html.
The Web Manager files are hidden and are incorporated directly into the firmware image but may
be overridden by placing the appropriate file in the appropriate directory on the AR embedded
device server file system.
Web Manager files can be retrieved and overridden with the following procedure:
1. FTP to the MatchPort AR device.
2. Make a directory (mkdir) and name it http/config
3. Change to the directory (cd) that you created in step 2. (http/config)
4. Get the file by using get <filename>
5. Modify the file as required or create a new one with the same name
6. Put the file by using put <filename>
7. Type quit. The overriding files appear in the file system’s http/config directory.
8. Restart any open browser to view the changes.
9. If you wish to go back to the default files in the firmware image, simply delete the overriding
files from the file system.
Short and Long Name Customization
Short and long names may be customized in Web Manager according to the directions in System
Settings. The names display in the CLI show command and in the System web page in the Current
Configuration table. The short name is used for the show command. Both names display in the CLI
Product Type field in the following example:
(enable)# show
The long and short names appear in the Product Type field in the following format:
Product Type: <long name> (<short name>)
For example:
(enable)# show

Appendix C: Binary to Hexadecimal Conversions
Many of the unit’s configuration procedures require you to assemble a series of options
(represented as bits) into a complete command (represented as a byte).
The resulting binary value must be converted to a hexadecimal representation.
Use this chapter to learn to convert binary values to hexadecimals or to look up hexadecimal
values in the tables of configuration options. The tables include:
Command Mode (serial string sign-on message)
AES Keys
Converting Binary to Hexadecimal
Conversion Table
Hexadecimal digits have values ranging from 0 to F, which are represented as 0-9, A (for 10), B
(for 11), etc. To convert a binary value (for example, 0100 1100) to a hexadecimal representation,
treat the upper and lower four bits separately to produce a two-digit hexadecimal number (in this
case, 4C). Use the following table to convert values from binary to hexadecimal.

Scientific Calculator
Another simple way to convert binary to hexadecimal is to use a scientific calculator, such as the
one available on the Windows operating systems. For example:
1. On the Windows Start menu, click Programs > Accessories > Calculator.
2. On the View menu, select Scientific. The scientific calculator appears.
3. Click Bin (Binary), and type the number you want to convert.
4. Click Hex. The hexadecimal value appears.
