Hi all

last command generates a core dump, do you have any suggestion?

newton:/home/root#last
Memory fault(coredump)
newton:/home/root#uname -a
HP-UX newton B.11.00 A 9000/800 164434671 two-user license
newton:/home/root#

Best Regards
Murat

You probably have a corrupt wtmp. As a test, you can "cp" the /var/tmp/wtmp file to some other name and then zero the real one with "> /var/tmp/wtmp", log in and out a couple of times and test the "last" command.

# cp /var/adm/btmp /var/adm/btmp.old
# cp /var/adm/wtmp /var/adm/wtmp.old
# cat /dev/null > /var/adm/wtmp
# cat /dev/null > /var/adm/btmp

check it now

Murat,

The btmp and wtmp files may be corrupted. Empty them to make last command work.

HTH,
Umapathy
