Incorrect user ids being logged in SU log file

[Managed Services]

Whenever I use the SU command as my own adminstration login, the appears in the SU log file as a totally separate user id. If I log in later, another different user id may appear as myself, or the same login id may appear as earlier. My own login id does not appear.
Does anyone know why this may be??

Usually this is related to /etc/utmp and wtmp. Verify corruption with these commands:

# last account
# finger account

Remove corruption :

# cat /dev/null > /etc/utmp
# cat /dev/null > /etc/wtmp

NOTE: Never >/etc/utmp. Althought this zeros out the file it doesn't remove the corruption.

Hi,

This is the classic symptom of utmp/utmpx corruption. There is a patch - PHNE_24829:

http://www2.itrc.hp.com/service/patch/patchDetail.do?patchid=PHNE_24829&context=hpux:800:11:11

that addresses the telnetd caused corruption.
We had the same problem & this patch fixed the problem.
NOTE that there are special instructions on this patch that *must* be followed for the fix to work.

HTH,
Jeff
