Which audit log? The lastlog?
LAST,LASTB(1) Linux System Administrator's Manual LAST,LASTB(1)
-d For non-local logins, Linux stores not only the
host name of the remote host but its IP number as
well. This option translates the IP number back
into a hostname.
My SSH lines in auth.log give the IP address. My xinetd logs IP addresses.
Which services are still logging only hostnames?
