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