EDS User Guide

2: Introduction

Additional Features
Modem Emulation
In modem emulation mode, the EDS 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 EDS enables 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 EDS with the Evolution OS™ uses industrystandard tools for configuration, communication, and control. For example, the 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.

VIP Access
Virtual IP Access is the Lantronix technology that solves the access-through-firewall problem. With
VIP Access, the EDS can act as a ManageLinx DSC and provide direct access to your equipment
behind a firewall.

SNMP Management
The EDS 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 EDS.

XML-Based Architecture and Device Control
XML is a fundamental building block for the future growth of M2M networks. The EDS 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 EDS 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 EDS the highest level of networking security possible. This ‘data
center grade’ protection ensures that each device on the M2M network carries the same level of
security as traditional IT networking equipment in the corporate data center.

EDS User Guide

2: Introduction
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 EDS has robust defenses to hostile Internet
attacks such as denial of service (DoS), which can be used to take down the network. Moreover,
the EDS cannot be used to bring down other devices on the network.
You can use the EDS 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 EDS 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.

Troubleshooting Capabilities
The EDS 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 EDS, including CPU utilization and total stack
space available.

Configuration Methods
After installation, the EDS 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
EDS 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 Using DeviceInstaller
(on page 41).

EDS User Guide

2: Introduction
Web Manager: Through a web browser, configure the EDS settings using the Lantronix Web
Manager. See Configuration Using Web Manager (on page 43).
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 EDS Command Reference Guide for instructions and available commands.)
XML: The EDS 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 EDS Command Reference Guide 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 2-4 Sample Hardware Address

00-20-4A-14-01-18

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 EDS:


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)



UDP Port 161: SNMP



TCP Port 21: FTP



UDP Port 69: TFTP



UDP Port 514: Syslog



TCP Port 515: LPD



UDP Port 30718: LDP (Lantronix Discovery Protocol) port



TCP/UDP Port 10001: Tunnel 1

support only one line while other device networking products (such as EDS2100,
EDS4100, XPort AR, EDS8/16PS and EDS8/16/32PR) 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 43) or the EDS Command Reference for the full list of commands.
The EDS 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 EDS 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 EDS 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 EDS Disconnect
Mode observes the defined event occur, it will disconnect both Accept Mode and Connect
Mode connections on that port.

When any character comes in through the serial port, it gets copied to both the Connect Mode
connection and the Accept Mode connection (if both are active).
View statistics and configure a specific tunnel by using the Tunnel web page. When you select
Tunnel from the Main Menu, tunnels available for your product will display. Select a specific tunnel

6. Repeat above steps as desired, according to additional tunnel(s) available on your product.

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.
3. Select Packing Mode. The Packing Mode page for the specific tunnel appears.

receiving this character, the device sends out the queued data.
The data is packed until the specified send character is
encountered. Similar to a start or stop character, the device packs
the data until it sees the send character. The device then sends the
packed data and the send character in the packet. Applies only if
the Packing Mode is Send Character.
Enter the trailing character (single printable or control). This
character is sent immediately following the send character. This is
an optional setting. If a trailing character is defined, this character is

Tunnel – Accept Mode
Controls how a specific tunnel number behaves when a connection attempt originates from the
network. In Accept Mode, the EDS 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 EDS 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 EDS supports IAC codes. It drops the IAC codes when Telnetting and does
not forward them to the serial port).

Accept Mode has the following states:


Disabled (never a connection)



Enabled (always listening for a connection)



Active if it receives any character from the serial port



Active if it receives a specific (configurable) character from the serial port (same start
character as Connect Mode’s start character)



Modem control signal



Modem emulation

To configure the Accept Mode of 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 Accept Mode. The Accept Mode page for the specific tunnel appears.

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 EDS device will make a
connection only if it can resolve the address. For DNS names, the EDS 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 EDS is
the SSH client. Ensure the EDS SSH client username is configured on the remote SSH server
before using it with the EDS.



SSL



UDP
Is only available in Connect Mode because it is a connectionless protocol. For Connect Mode
using UDP, the EDS 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:

Note: While in the “Any Character” or “Start
Character” connection modes, the EDS
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).



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.



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 71 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.

Tunnel – Modem Emulation
A tunnel in Connect Mode can be initiated using modem commands incoming from the Serial Line.
This page enables you to configure the modem emulation settings when you select Modem
Emulation as the Tunnel Connect Mode type.
The Modem Emulation Command Mode supports the standard AT command set. For a list of
available commands from the serial or Telnet login, enter AT?. Use ATDT, ATD, and ATDP to
establish a connection. All of these commands behave like a modem. For commands that are valid
but not applicable to the EDS, an “OK” message is sent (but the command is silently ignored).
The EDS 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.

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, :. The port number cannot be entered on its own.
For ATDT and ATDP commands less than 255 characters, the EDS 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 EDS reverts to modem emulation mode. By

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 EDS 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 EDS 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 EDS SSH server.

This page has four links at the top for viewing and changing SSH server host keys, SSH server
authorized keys, SSH client known hosts, and SSH client users.

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 EDS.

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

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 104).
SSL uses digital certificates for authentication and cryptography against eavesdropping and
tampering. Sometimes only the server is authenticated, sometimes both server and client. The
EDS 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 EDS 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:

Certificate

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 required 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 another 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, SSL Tunneling in Accept mode, and/or EAP-TLS, the EDS needs a personal
certificate with a matching private key to identify itself and sign its messages. When using SSL
Tunneling in Connect mode and/or EAP-TLS, EAP-TTLS or PEAP, the EDS 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 EDS 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 EDS, 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 generate your own. A few
utilities exist to generate self-signed certificates or sign certificate requests. The EDS 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
EDS.
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 EDS currently only accepts separate PEM files. The key needs to be
unencrypted.

SSL Utilities
Several utilities exist to convert between the formats.

OpenSSL
Open source 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.

Steel Belted RADIUS
Commercial RADIUS server by Juniper Networks that provides a GUI administration interface. It
also provides a certificate request and self-signed certificate generator. The self-signed certificate
has extension .sbrpvk and is in the PKCS12 format. OpenSSL can convert this into a PEM format
certificate and key by using the following commands in the order shown:
openssl pkcs12 -in sbr_certkey.sbrpvk -nodes -out sbr_certkey.pem
The sbr_certkey.pem file contains both certificate and key. If loading the SBR certificate into EDS
as an authority, you will need to edit it.
1. Open the file in any plain text editor.
2. Delete all info before the following: “----- BEGIN CERTIFICATE-----“
3. Delete all info after the following: “----- END CERTIFICATE-----“
4. Save as sbr_cert.pem. SBR accepts trusted-root certificates in the DER format.
5. Again, OpenSSL can convert any format into DER by using the following commands in the
order shown:

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.

XML Settings
EDS allows for the configuration of devices by using XML configuration records (XCRs). You can
export an existing configuration for use on other EDS 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 EDS 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:
:;:;...
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 is followed by a colon and the instance value . Each : value is
separated with a semicolon. If a group has no instance, specify the group name only.
The number of lines available for importing and exporting differ between Lantronix DeviceLinx
products. The screenshots in this chapter represent one line, as available, for example, on an
XPort Pro and EDS1100. However, other device networking products (such as EDS2100,
EDS4100, XPort AR, EDS8/16PS and EDS8/16/32PR) support additional lines.

16: VIP Settings
VIP (Virtual IP) takes advantage of the Lantronix ManageLinx technology that solves the accessthrough-firewall problem. ManageLinx utilizes existing network infrastructure to create a virtual
device network (VDN). The VDN provides direct access to only authorized equipment, behind
firewalls, from anywhere via the net.
ManageLinx is a secure and totally transparent remote access solution. The VDN technology
enables you to create dedicated TCP/IP connections between any two devices, using easily
deployed hardware appliances. There is no client software to install. No changes are required to
network software or applications at either end of the connection.
The VDN hardware consists of a publicly accessible Device Services Manager (DSM) and
individual Device Services Controller (DSC) appliances in multiple locations. Together, these two
components enable you to set up and manage individual Virtual IP (VIP) addresses and routes.
The EDS, with VIP enabled, takes the place of a DSC and provides direct access to your
equipment.
The EDS supports both Accept and Connect Mode tunneling through VIPs. Configuring an EDS to
use VIP Access involves:


Obtaining a Bootstrap File



Importing the Bootstrap File



Enabling VIP



Configuring Tunnels to Use VIP

Once the EDS is configured and enabled to use VIPs, it will immediately attempt to establish a
conduit with the ManageLinx DSM. Once the conduit is up, tunneling via VIP Access is ready to
go. This chapter also contains the following VIP sections:


Virtual IP (VIP) Statistics



Virtual IP (VIP) Counters



Virtual IP (VIP) Configuration

Obtaining a Bootstrap File
The ManageLinx XML bootstrap file is an XML file that contains the information required to contact
and authenticate to a DSM. This file must be generated and sent to you by the DSM administrator.
See the ManageLinx documentation for more details.

Importing the Bootstrap File
To configure an EDS to use VIP Access, import the bootstrap file as you would any XML
Configuration Record (XCR). For instructions on importing XCRs see Advanced Settings (on page
134).

EDS User Guide

147

16: VIP Settings

Enabling VIP
Once the bootstrap file has been imported, VIP Access can be enabled and a conduit with the
DSM will be established. The VIP Statistics shows the current state of the conduit. When
configured correctly, a conduit with the DSM will be maintained at all times.

Configuring Tunnels to Use VIP
Configuring Connect Mode tunnels to use VIP is a simple matter of configuring a tunnel as is
normally done, but also enabling VIP in the Tunnel Host settings, and using a VIP Name for the
address.
VIP Accept Mode tunnels do not require special configuration. If VIP access is enabled (in the VIP
configuration page), then VIP Accept Mode requests from a ManageLinx device will be accepted.

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 EDS file system.
Web Manager files can be retrieved and overridden with the following procedure:
1. FTP to the EDS 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
5. Modify the file as required or create a new one with the same name
6. Put the file by using put
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 on page 132 of Chapter 14: Maintenance and Diagnostics 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:

Appendix B - 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.
