Alavi [ssa@unity.ncsu.edu] (919)467-7909 (H) ======== : (919)515-8063 (W) ipcs reads the IPC status from the file /dev/kmem. I just tried this from another user and it worked, went into root and changed the permissions and it failed with the message ipcs: no memory file so you might want to check the permissions on the file , maybe try changing it to rw-r--r-- (644). If this gives you a security headache - and it does for some people then try putting the user in the same group as kmem (so they have the same gid - group id) with an entry in /etc/groups. You wont need to reboot to try it out. Let me know how you get on ..Anthony ----------- / MMMM GGGG \ | M M M G G | Anthony Firmin afirmin@ingres.com | M M M G | Ingres Technical Support | M M M G GG | 510 748 2905 | M M M G G | / \ M M GGGG / "MGB's and current raves" -8-) ----------- \
