User Manual
Logging into a device connected to the console server may require authentication.
For Unauthenticated Telnet the default port address is IP Address _ Port (6000 + serial port #)
i.e. 6001 – 6048
Unauthenticated SSH
This enables SSH access to the serial port without authentication credentials. When
a user accesses the console server to Telnet to a serial port, they are given a login prompt.
With unauthenticated SSH they connect directly through to the port without any console server
login challenge.
This mode is used when you have another system managing user authentication and access
privileges at the serial device level but wish to encrypt the session across the network.
Logging into a device connected to the console server may require authentication.
For Unauthenticated Telnet the default port address is IP Address _ Port (7000 + serial port #)
i.e. 7001 – 7048
The <username>: method of port access (as described in the above
SSH
section) always
requires authentication.
Web Terminal
This enables web browser access to the serial port via
Manage > Devices: Serial
using the
Management Console's built in AJAX terminal. Web Terminal connects as the currently
authenticated Management Console user and does not re-authenticate. See section 12.3 for
more details.
IP Alias
Enable access to the serial port using a specific IP address, specified in CIDR format. Each
serial port can be assigned one or more IP aliases, configured on a per-network-interface
basis. A serial port can, for example, be made accessible at both 192.168.0.148 (as part of the
internal network) and 10.10.10.148 (as part of the Management LAN). It is also possible to
make a serial port available on two IP addresses on the same network (for example,
192.168.0.148 and 192.168.0.248).
These IP addresses can only be used to access the specific serial port, accessible using the
standard protocol TCP port numbers of the console server services. For example, SSH on
serial port 3 would be accessible on port 22 of a serial port IP alias (whereas on the console
server’s primary address it is available on port 2003).
This feature can also be configured via the multiple port edit page. In this case the IP
addresses are applied sequentially, with the first selected port getting the IP entered and
subsequent ones getting incremented, with numbers being skipped for any unselected ports.
For example, if ports 2, 3 and 5 are selected and the IP alias 10.0.0.1/24 is entered for the
Network Interface, the following addresses are assigned:
Port 2: 10.0.0.1/24
Port 3: 10.0.0.2/24
Port 5: 10.0.0.4/24
IP Aliases also support IPv6 alias addresses. The only difference is that addresses are
hexadecimal numbers, so port 10 may correspond to an address ending in A, and 11 to one
ending in B, rather than 10 or 11 as per IPv4.
