Discussion

The kshell service offers a higher degree of security than traditional rsh services. However, it still does not use encrypted communications. The recommendation is to use SSH wherever possible instead of kshell. If the kshell service is used, you should use the latest Kerberos version available and must make sure that all the latest patches are installed.

Check Content

From the command prompt, execute the following command: 
# grep "^kshell[[:blank:]]" /etc/inetd.conf

If there is any output from the command, this is a finding.

Fix Text

In "/etc/inetd.conf", comment out the "kshell" entry by running command:  
# chsubserver -r inetd -C /etc/inetd.conf -d -v 'kshell' -p 'tcp'

Restart inetd:
# refresh -s inetd
