Fix Recommendation

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.

Check Contents

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.
