Check Text (C-215306r991593_chk)
From the command prompt, run the following command to check if "ListenAddress" is defined in SSH config file:
# grep -i ListenAddress /etc/ssh/sshd_config | grep -v '^#'
ListenAddress 10.17.76.74
If no configuration is returned, or if a returned listen configuration contains addresses not permitted, this is a finding.
Fix Text (F-16502r294370_fix)
Edit the SSH daemon config file and add/modify the "ListenAddress" network addresses:
# vi /etc/ssh/sshd_config
Restart SSH daemon:
# stopsrc -s sshd
# startsrc -s sshd
