Check Text ( C-27765r2_chk )
Check the SSH client configuration for allowed MACs. Procedure: # grep -i macs /etc/ssh/ssh_config \| grep -v '^#' If no lines are returned, or the returned MACs list contains any MAC that is not hmac-sha1 or a better hmac algorithm that is on the FIPS 140-2 approved list, this is a finding.

Fix Text (F-24006r2_fix)
Edit the SSH client configuration and remove any MACs that are not hmac-sha1 or a better hmac algorithm that is on the FIPS 140-2 approved list. If necessary, add a MACs line.
