Configuring Telnet Access When Using SSHD

Configuring Telnet Access When Using SSHD

By default, Telnet access to the CSS is enabled. When you use SSHD, you can disable nonsecure Telnet access to the CSS. To enhance security when using SSHD, we recommend that you disable Telnet access. Use the global restrict telnet command to disable Telnet access to the CSS.

To disable Telnet access, enter:

(config)# restrict telnet

To reenable Telnet access to the CSS, enter:

(config)# no restrict telnet

Showing SSHD Configurations

Use the show sshd command to display SSHD configurations. This command provides the following options:

•show sshd config - Displays the SSHD configuration

•show sshd sessions - Displays a summary of the current active SSHD server sessions. The command displays data only if an SSH client is currently configured.

•show sshd version - Show the current version of the SSHield package running in the CSS.

To display the SSHD configuration, enter:

#show sshd config

Table 2-1describes the fields in the show sshd config command output.
