4. Serial Port, Host, Device and User Conﬁguration

Web Terminal Selecting Web Terminal 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 13.3

Terminal Connection for 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.

For example, a serial port can 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 (e.g., 192.168.0.148 and

192.168.0.248).

These IP addresses can only be used to access the speciﬁc serial port 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 from the multiple port edit page. In this case, the IP addresses

are applied sequentially. The ﬁrst selected port receives the IP address entered, while subsequent

ports receive incremental addresses with numbers being skipped for any ports unselected. 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 will be assigned:

Port 2: 10.0.0.1/24 Port 3: 10.0.0.2/24 Port 5: 10.0.0.4/24

Accumulation Period By default, once a connection has been established for a particular serial port (such as an RFC2217

redirection or telnet connection to a remote computer), any incoming characters on that port are

forwarded over the network on a character-by-character basis. The accumulation period changes

this by specifying a period of time that incoming characters will be collected before being sent as a

packet over the network.

Escape Character This enables you to change the character used for sending escape characters. The default is ~.

Power Menu This setting enables the shell power command so a user can control the power connection to

a managed device from command line when they are connected to the device via telnet or SSH. To

operate, the managed device must be set up with both its serial port connection and power

connection conﬁgured. The command to open the power menu is ~p

Single Connection This setting limits the port to a single connection, so multiple users have access privileges for a

particular port. Only one user at a time can access that port (port “snooping” is not permitted).
