Effective User ID

[Robert Busick]

Running an HP9000 D250(?), HP-UX 10.20 with Trusted System turned on. Experienced extreme slow down in response time and rebooted the system w/o recognizing the cause was that the /var/tmp directory had filled to capacity.

Ever since the reboot users are no longer able to print (only root). They get a message - unable to set effective user id (9) and trusted users are no longer able to use su (same reason).

I've deleted and recreated the print spool twice and no difference.

From /etc/rc.config.d set the clean_tmps and clean_uncp to clean temp files at system startup. Reboot your system to clear the locks.

What are the permission settings for /usr/bin/lp?

They should be:-
-r-sr-xr-x 1 root bin .... lp

[Alex Glennie]

check the /usr/bin/lp file it should be :

-r-sr-xr-x root bin lp

You did not say if you made space on /var/tmp since the reboot. If you haven't, you probably want to do that...and then edit /etc/rc.config.d/clean_tmps and set the CLEAR_TMP variable to 1

Next, run

# /sbin/init.d/clean_tmps start

to clean the temp files
