Dynamic Host Configuration Protocol (DHCP)
You can use Dynamic Host Configuration Protocol (DHCP) to automatically assign IP addresses, deliver
IP stack configuration parameters such as the subnet mask and default router, and provide other
configuration information. For more details, see Assign an IP address using DHCP.
Auto IP
The Auto-IP protocol automatically assigns an IP address from a reserved pool of standard Auto-IP
addresses to the computer on which it is installed. Digi devices automatically obtain their IP
addresses from a DHCP server. If the DHCP server is unavailable or nonexistent, Auto-IP assigns the
device an IP address. For more details, see Assign an IP address using Auto-IP.
Simple Network Management Protocol (SNMP)
Simple Network Management Protocol (SNMP) is a protocol for managing and monitoring network
devices. SNMP architecture enables a network administrator to manage nodes—servers,
workstations, routers, switches, hubs, and so on—on an IP network; manage network performance,
find and solve network problems, and plan for network growth. For more information on SNMP as a
device-management interface, see Simple Network Management Protocol (SNMP).
Secure Sockets Layer (SSL)/Transport Layer Security (TLS)
Secure Sockets Layer (SSL)/Transport Layer Security (TLS) provides authentication and encryption for
ConnectPort LTS products. For more information, see Security features in Digi devices.
Telnet
ConnectPort LTS devices support the following types of telnet connections:
ConnectPort LTS features Serial data communication over TCP and UDP
Digi ConnectPort LTS User Guide 15
nTelnet client
nTelnet server
nReverse telnet, often used for console management or device management
nTelnet autoconnect
For more information on these connections, see Network connections and data paths. You can enable
or disable access to telnet network services.
Remote login (rlogin)
You can enable or disable access to rlogin service. When enabled, users can use rlogin to remotely sign
in to systems.
Line Printer Daemon (LPD)
The Line Printer Daemon (LPD) allows network printing over a serial port. Each serial port has a
dedicated LPD server that is independently configurable. You can enable or disable access to LPD
service.
HyperText Transfer Protocol (HTTP)/HyperText Transfer Protocol
over Secure Socket Layer (HTTPS)
Digi provides web pages that you can use to configure the ConnectPort LTS product. You can secure
these web pages by requiring a user login.
Internet Control Message Protocol (ICMP)
You can display ICMP statistics, including the number of:
nMessages received
nBad messages received
nDestination unreachable messages received
Point-to-Point Protocol (PPP)
The Point-to-Point Protocol (PPP) transports multi-protocol packets over point-to-point links. PPP is
responsible for:
nEncapsulating the data packet
nAllowing the server to inform the dial-up client of its IP address (or client to request the IP
address)
nAuthenticating the exchange
nNegotiating multiple protocols
nReassembling the data packet for network communication
Advanced Digi Discovery Protocol (ADDP)
The ADDP runs on any operating system capable of sending multicast IP packets on a network. ADDP
allows the system to identify all ADDP-enabled ConnectPort LTS products attached to a network by
ConnectPort LTS features RealPort software
Digi ConnectPort LTS User Guide 16
sending out a multicast packet. The ConnectPort LTS products respond to the multicast packet and
identify themselves to the client sending the multicast.
ADDP communicates with the IP stack using UDP. The IP stack can receive multicast packets and
transmit datagrams on a network.
You can enable or disable access to ADDP service, but you cannot change the network port number for
ADDP from its default.
Secure Shell (SSH)
ConnectPort LTS products support Secure Shell (SSH) as a connection method and the following types
of SSH connections: Reverse SSH and SSH Autoconnect. Limited use of SSH via SSH client is available
from the Linux command line/bash shell. For more information on these connections, see Network
connections and data paths. You can enable or disable access to Secure Shell network services.
RealPort software
Digi’s RealPort software leverages the TCP/IP network infrastructure to provide a virtual connection
to serial devices. The software is installed directly on the server and allows applications to talk to
devices via a Digi device server or terminal server over a network.
RealPort software is a COM port redirector that allows multiple connections to multiple ports over a
single TCP/IP connection. This means RealPort supports the maximum number of remote devices. The
number is restricted only by the operating system and server processing power.
Other unique features include full hardware and software flow control, as well as tunable latency and
throughput. With these, RealPort ensures optimum performance since data transfer is adjusted
according to specific application requirements. It also provides connection recovery—after a network
interruption RealPort automatically reconnects the device to the COM port without the application
knowing there was a failure.
Encrypted RealPort
ConnectPort LTS devices also support RealPort software with encryption. Encrypted RealPort offers a
secure Ethernet connection between the COM or TTY port and a device server or terminal server.
Encryption prevents internal and external snooping of data across the network by encapsulating the
TCP/IP packets in an SSL connection and encrypting the data using Advanced Encryption Standard
(AES).
Digi’s RealPort with encryption driver has earned Microsoft’s Windows Hardware Quality Lab (WHQL)
certification.
Drivers are available for a wide range of operating systems, including Microsoft Windows and Linux x32
and x64 based operating systems, as well as other versions of Unix. See the RealPort Compatibility OS
List in the Digi Knowledge Base for a detailed list of supported operating systems. It is ideal for
financial, retail/point-of-sale, government, or any application requiring enhanced security to protect
sensitive information.
Alarms
You can configure ConnectPort LTS products to issue alarms, in the form of email messages or SNMP
traps, when certain device events occur, including data patterns detected in the data stream
Configuring Digi devices to issue alarms allows you to know when events occur. For more information
on configuring alarms, see Alarms Configuration.
ConnectPort LTS features Modem emulation
Digi ConnectPort LTS User Guide 17
Modem emulation
ConnectPort LTS devices include a configuration profile that allows the device to emulate a modem.
Modem emulation sends and receives modem responses to a serial device over TCP/IP (including
Ethernet) instead of Public Switched Telephone Network (PSTN). The modem emulation profile allows
you to maintain a current software application but using it over the less expensive Ethernet network.
In addition, you can enable or disable telnet processing on the incoming and outgoing modem-
emulation connections. For information on the modem-emulation commands that ConnectPort LTS
products support, see the Digi Connect® Family Command Reference. See Select Port Profile for more
information.
Ethernet bridging
You can use Ethernet bridging to join multiple Ethernet networks together so that the joined
networks appear as one Ethernet network. Ethernet bridging combines an Ethernet interface with
one or more physical Ethernet interfaces under the umbrella of a single bridge interface. The Ethernet
bridge is a software switch that can connect multiple Ethernet interfaces (physical or virtual) on a
single machine while sharing a single IP subnet.
Use the script file, brmode (/etc/init.d/brmode), to enable or disable Ethernet bridging. (Ethernet
bridging is supported only through the command line interface.)
To enable Ethernet bridging, run the following command:
# service brmode start
The IP address of the eth0 interface becomes the common IP address for the bridging mode interface
(br0).
After enabling Ethernet bridging, the eth0 and eth1 addresses disappear. There is a delay of a few
minutes while the system automatically changes the physical interface from the Ethernet 1 port to
Ethernet 2 port.
Note Enable the eth1 (IP address #2) interface before starting Ethernet bridging.
To disable Ethernet bridging, run the following command:
# service brmode stop
To customize Ethernet bridging options, modify /etc/init.d/brmode. See the brctl Linux manpage for
details.
To remove bridging messages from the serial console, run the following command:
# brctl setageing br0 0
To automatically start the Ethernet bridging service at each boot, add the following commands to the
rc.user file:
service brmode start
brtcl set ageing br0 0
For more information on using the rc.user file, see Using the rc.user file and the Digi Knowledgebase.

nEnable secure remote login through Remote Authentication Dial-In User Service (RADIUS) and
Lightweight Directory Access Protocol (LDAP).
Encryption
Encrypted RealPort offers encryption for the Ethernet connection between the COM/TTY port and the
ConnectPort LTS product. Encryption prevents internal and external snooping of data across the
network by encapsulating the TCP/IP packets in an SSL connection and encrypting the data using the
Advanced Encryption Standard (AES) security algorithm.
Encryption methods are as follows:
nStrong TLS V1.0/V1.2-based encryption:
lDES (58/64-bit)
l3DES (168/192-bit)
lAES (128/156/192/256-bit)
SNMP security
SNMP security options include:
nYou can configure SNMP set commands to use SNMP read-only. Digi recommends changing the
public and private community names to prevent unauthorized access to the Digi device
(SNMPv1/v2c).
nYou can use SNMPv3 support for enhanced security through SNMP.
ConnectPort LTS features Configuration management
Digi ConnectPort LTS User Guide 19

Get started with ConnectPort LTS products Configuring IP addresses
Digi ConnectPort LTS User Guide 21
Configuring IP addresses
The IPaddress mode determines how IPaddresses are assigned. There are two modes for assigning
IPaddresses:
nDynamic: Allows IP addresses to be automatically assigned using the Dynamic Host
Configuration Protocol (DHCP) and/or Auto Private IP Addressing (APIP or AUTO IP).
nStatic: Requires you to assign a static IP address using any available configuration interface.
By default, ConnectPort LTS devices are configured to dynamically assign addresses using DHCP.
Even if a DHCP server is available for dynamically assigning IP addresses, static addresses may work
better for your network configuration. Once set, static IP addresses do not change and other network
devices can always find the device by its IP address. With dynamic settings, the DHCP server can
change the IP address frequently or infrequently depending on how your network administrator has
configured the network.
When the IP address changes, network devices configured to talk to the ConnectPort LTS device can
no longer access the device. In this case, you must locate the Digi device using the Digi Device
Discovery utility and reconfigure the other network devices that need to communicate with the
ConnectPort LTS device.
The following table summarizes methods for assigning an IP address.
Method Description
Digi Device
Discovery
Utility
Use the Digi Device Discovery utility to search for and display Digi device, as well as
change configuration settings. See Use Digi Device Discovery utility to sign in to the
web interface.
LCD panel Use the LCD panel on ConnectPort LTS products to perform basic configuration
tasks, including setting the IP address, as well as monitoring and diagnostics tasks.
See ConnectPort LTS LCD interface.
Dynamic
Host
Configuration
Protocol
(DHCP)
Use DHCP from the web interface to automatically assign IP addresses, to deliver IP
stack configuration parameters such as the subnet mask and default router, and to
provide other configuration information. All ConnectPort LTS devices have a DHCP
client enabled by default. Contact your network administrator to find out if a DHCP
server is available. See Assign an IP address using DHCP.
Auto Private
IP Addressing
(APIPA)
also known
as Auto-IP
Use APIPA to automatically assign an IP address to the Digi device from a reserved
pool of standard Auto-IP addresses on a DHCP server. If the DHCP server is
unavailable or there is no DHCP server, Auto-IP assigns the device an IP address. If
DHCP is enabled or responds after ADDP is used, both override the Auto-IP address
previously assigned. See Assign an IP address using Auto-IP.
Static IP Manually assign a specific IP address to a device through the Digi Device Discovery
Utility, the web interface, LCD, or the command-line interface. Once set, these
settings do not change. The IP address and subnet mask are mandatory. Additional
settings may be needed for some functions. Contact your network administrator for
the required values.
Get started with ConnectPort LTS products Configuring IP addresses
Digi ConnectPort LTS User Guide 22
Method Description
Access via
the console
port
Use the port, labeled console port on ConnectPort LTS device to configure device
settings. This port allows for a login with serial settings of 9600 baud, 8 data bits,
and 1 stop bit. The standard serial ports do not provide a login by default and do not
provide access to configuration settings. Only the console port allows access to
configuration settings.
Command-
line interface
Use the command-line interface to configure device settings. See Assign an IP
address from the command-line interface.
Assign an IP address using DHCP
You can assign an IP address using Dynamic Host Configuration Protocol (DHCP). DHCP is an Internet
protocol for automating the configuration of computers that use IP. You can use DHCP to
automatically assign IP addresses and deliver IP stack configuration parameters.
The following procedure assumes that you configured the Digi device as a DHCP client. The Digi
devices discussed in this document are configured as a DHCP client by default.
To configure an IP address using DHCP:
1. Verify the Digi device is not powered on.
2. If desired, set up a permanent entry for the Digi device on a DHCP server. While this is not
necessary to obtain an IP address via DHCP, setting up a permanent entry saves the IP
address after the device is rebooted.
3. Connect the Digi device to the network and power it on. DHCP assigns the IP address
configured in step 2 automatically.
Assign an IP address using Auto-IP
The standard Automatic Private IP Addressing (APIPA or Auto-IP) protocol automatically assigns the
IP address from a group of reserved IP addresses to the device on which Auto-IP is installed. Use Digi
Device Discovery or ADDP to find the Digi device and assign it a new IP address that is compatible with
your network. When you plug in the device, Auto-IP automatically assigns the IP address. Auto-IP
addresses are typically in the 169.254.x.x address range. See Use Digi Device Discovery utility to sign in
to the web interface for instructions on using Digi Device Discovery.
Assign an IP address from the command-line interface
Use the set network command to configure an IP address from the command line. The set network
command includes the following parameters:
nindex=(1-4): The Ethernet interface index number.
nip_v4=device ip: The IP address for the device.
ngateway_v4=gateway: The network gateway IP v4 address.
ngarp=seconds: The frequency of Gratuitous ARP (GARP) announcements, in seconds, which are
a broadcast announcement to the network of a device’s MAC address and the IP address.
nsubmask_v4=device submask: The device subnet mask for the IP v4 address.
nmode_v4=(none|static|dhcp): The configuration mode of the IP v4 address.
Get started with ConnectPort LTS products Test the IP address assignment
Digi ConnectPort LTS User Guide 23
nip_v6=device ip: The IP v6 address for the device.
ngateway_v6=gateway: The IP address for the IP v6 network gateway.
nsubmask_v6=gateway: The device subnet mask for the IP v6 address.
nmode+v6=(none|static|dhcp): The configuration mode of the IP v6 address.
For example:

Network connections and data paths
ConnectPort LTS devices allow for several kinds of connections and paths for data flow between
ConnectPort LTS devices and other entities. You can group these connections into two main
categories:
nNetwork services, in which a remote entity initiates a connection to a Digi device.
nNetwork/serial clients, in which a Digi device initiates a network connection or opens a serial
port for communication.
The following topics describe the effects of enabling features and selecting settings when configuring
ConnectPort LTS devices.
Network services
A network service connection occurs when a remote entity initiates a connection to a Digi device.
There are several categories of network services:
nNetwork services associated with specific ports
nNetwork services associated with serial ports in general
nNetwork services associated with the command-line interface
Network services associated with specific ports
The following list details network services associated with specific ports.
nReverse telnet: A remote entity establishes a telnet connection to a Digi serial port. Data
passes transparently between the telnet connection and a named serial port.
nReverse raw socket: A remote entity establishes a raw TCP socket connection to a Digi serial
port. Data passes transparently between the socket and a named serial port.
nReverse TLS socket: A remote entity establishes an encrypted raw TCP socket connection to a
Digi serial port. Data passes transparently to and from a named serial port.
nLPD: A remote entity establishes a TCP connection to a named serial port. The Digi device
interprets the LPD protocol and sends a print job out of the serial port.
nModem emulation, also known as pseudo-modem (pmodem): A remote entity establishes a
TCP connection to a named serial port. This connection is interpreted as an incoming call to
the pseudo-modem.
nConsole Mgmt: Allows a TCP connection to a serially-attached console.
Digi ConnectPort LTS User Guide 30
Network connections and data paths Network/serial clients
Digi ConnectPort LTS User Guide 31
nModem: The Modem Profile allows you to attach modem devices to the serial port to establish
or receive connections from other systems and modems. Both the modem dial-in and bi-
directional options provide a login from the Digi device.
nReverse SSH: A remote entity establishes an SSH connection to a ConnectPort LTS serial port
and data passes transparently between the SSH connection and a named serial port.
Network services associated with serial ports in general
The following list details network services associated with serial ports in general.
nRealPort: A single TCP connection manages (potentially) multiple serial ports.
nModem emulation, also known as pseudo-modem (pool): A TCP connection to the pool port
is interpreted as an incoming call to an available pseudo-modem in the pool of available port
numbers.
nrsh: ConnectPort LTS products support a limited implementation of the remote shell (rsh)
protocol, in that a single service listens to connections and allows a command to be executed.
Only one class of commands is allowed: a single integer that specifies which serial port to
connect to. Otherwise, the resulting connection is somewhat similar to a reverse telnet or
reverse socket connection.
Network services associated with the command-line interface
The following list details network services associated with the command line interface (CLI).
nSSH: Use Secure Shell (SSH) to directly access a ConnectPort LTS command-line interface.
nTelnet: Use telnet to directly access a ConnectPort LTS command-line interface.
nRlogin: Perform a remote login (rlogin) to a ConnectPort LTS command-line interface.
Network/serial clients
A network/serial client connection occurs when a ConnectPort LTS product initiates a network
connection or opens a serial port for communication. There are several categories of network/serial
client connections:
nAutoconnect behavior client connections
nCommand-line interface (CLI)-based client connections
nModem emulation (pseudo-modem) client connections
Autoconnect behavior client connections
In client connections that involve autoconnect behaviors, a ConnectPort LTS product initiates a
network connection based on timing, serial activity, or serial modem signals. Autoconnect-related
client connections include:
nRaw TCP connection: The ConnectPort LTS initiates a raw TCP socket connection to a remote
entity.
Network connections and data paths Network/serial clients
Digi ConnectPort LTS User Guide 32
nTelnet connection: The ConnectPort LTS initiates a TCP connection using the telnet protocol
to a remote entity.
nSSH connection: The ConnectPort LTS initiates a TCP connection using the SSH protocol to a
remote entity.
nRaw TLS encrypted connection: The ConnectPort LTS initiates an encrypted raw TCP socket
connection to a remote entity.
nRlogin connection: The ConnectPort LTS initiates a TCP connection using the rlogin protocol
to a remote entity.
Command-line interface (CLI)-based client connections
CLI-based client connections are available for use when you establish a session with the ConnectPort
LTS products CLI. CLI-based client connections include:
nssh: Allows you to connect to a remote entity using the ssh protocol.
ntelnet: Allows you to connect to a remote entity using the telnet protocol.
nrlogin: Allows you to connect to remote entity using the rlogin protocol (bash only).
nscp: Allows you to transfer files (bash only).
nconnect: Begin communicating with a local serial port.
Note Additional communication methods include using a bash shell such as scp, tftp, nc, or using
Python.
Modem emulation (pseudo-modem) client connections
When a port is in the modem-emulation or pseudo-modem mode, it can initiate network connections
based on AT command strings received on the serial port. See the Digi Connect® Family Command
Reference on www.digi.com for modem emulation AT commands.

Digi Device Discovery utility
The Digi Device Discovery utility:
nLocates Digi devices on a network
nAllows you to open the web interface for discovered devices
nAllows you to configure network settings and reboot the device
Download the Digi Device Discovery utility.
In addition to quickly locating devices, the utility also lists device information, such as the device
address, firmware version, and whether it has been configured. It runs on any operating system that
can send multicast IP packets to a network. It sends out a User Datagram Protocol (UDP) multicast
packet to all Digi devices on the network. Digi devices that support ADDP reply to the UDP multicast
with their configuration information. Even Digi devices that do not yet have an assigned IP address or
are misconfigured for the subnet can reply to the UDP multicast packet and appear in the device
discovery results.
Note Personal firewalls, Virtual Private Network (VPN) software, and certain network equipment can
block device discovery. Firewalls block UDP ports 2362 and 2363 that ADDP uses to discover devices.
You can enable or disable access to the ADDP service, but you cannot change the network port
number for ADDP.
