Check Text ( C-28724r483098_chk )
Check for the existence of the files. The .rhosts and .shosts files are stored in home directories. (If a user does not have a home directory assigned in /etc/passwd, the root directory (/) is assigned as a default home directory.) Procedure (the first command is five lines long): # for homedir in `cut -d: -f6 /etc/passwd \| awk '$1 == "" {$1 = "/"} {print $1}'`; do ls -l $homedir/.rhosts; ls -l $homedir/.shosts; done # ls -l /etc/hosts.equiv # ls -l /etc/ssh/shosts.equiv If .rhosts, .shosts, hosts.equiv, or shosts.equiv are found, this is a finding.
