'who -b' not working

[Brad Marks]

who -b, who -r & who -t all return nothing. Other varities of who (who -u, for example) work just fine.
Any ideas why this should start happening?
TIA,
Brad

Could be a corrupt wtmp file. Try nulling it out with

> /var/adm/wtmp

Hi Brad ,

This could possibly a corrupted or missing /etc/btmp or /var/adm/wtmp file .

Hi Brad,

I'd suspect one of a few things:

1) Corrupt /etc/utmp
2) Corrupt /var/adm/wtmp
3) Corrupt /etc/inittab
4) kernel has been relinked but system hasn't been rebooted yet.

HTH,
Jeff

I guess clearing wtmp will fix it but, since I frequently use the 'last' command, I'll live with the problem until I reboot next weekend.
Thanks for the speedy replies, guys.
I appreciate your help.
