 Sorry for not getting back to you before now! Had lost this email
 in a pile of about 400 others. Thanks for starting to look at the issue
 for me. I suspect you are right, and that something is back resolving the
 hostnames before writing them into the utmp file. 'last' has the same
 erreft - downs the hostnames if the resolve.
