Have a puzzling issue here. I have some Sol 7/8 computers that are having a problem when I issue a "last -20" command. Some of the boxes report entries starting 6 months ago and others report nothing just "wtmp begins Mon Jun 15 06:40" (or some other date in the past).
I've looked at /var/adm/*tmpx and done a strings on them. They are being modified with new date (mod date changes) and I can see the new logins in the file when I do a strings on them. Any ideas?
