Incoming Telnet Connections and Time-outs

You can Telnet to your Oracle® Enterprise Session Border Controller. Using remote Telnet access, you can provision the Oracle® Enterprise Session Border Controller remotely through the management IP interface.

The Oracle® Enterprise Session Border Controller, when running on Acme Packet platforms can support up to 5 concurrent Telnet sessions. When running on other platform types, only 4 concurrent Telnet sessions are available. In both cases, only one Telnet session may be in configuration mode at a time.

Note:

Telnet does not offer a secure method of sending passwords. Using Telnet, passwords are sent in clear text across the network.

To Telnet to your Oracle® Enterprise Session Border Controller, you need to know the IP address of its administrative interface (wancom0/eth0). The wancom0/eth0 IP address of your Oracle® Enterprise Session Border Controller is found by checking the inet on ethernet value in the boot parameters or visible from the front panel display.

You can manage incoming Telnet connections from the ACLI:

• To set a time-out due to inactivity, use the telnet-timeout parameter in the system configuration. You can set the number of seconds that elapse before the Telnet connection or SSH connection is terminated. The default for this field is 0, which means that no time-out is being enforced.
• To view the users who are currently logged into the system, use the ACLI show users command. You can see the ID, timestamp, connection source, and privilege level for active connections.
• From Superuser mode in the ACLI, you can terminate the connections of other users in order to free up connections. Use the kill user command with the corresponding connection ID.
• From Superuser mode in the ACLI, you can globally enable and disable Telnet connections:
  • Telnet service is enabled by default unless explicitly disabled as shipped.
  • To disable Telnet, type the management disable telnet command at the Superuser prompt and reboot your system. The Oracle® Enterprise Session Border Controller then refuses any attempts at Telnet connections. If you want to restart Telnet service, type management enable telnet.
• If you reboot your Oracle® Enterprise Session Border Controller from a Telnet session, you lose IP access and therefore your connection.
