| Check Text (C-16504r294369_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 |
