- Hello,
-
- I just encountered something wierd, or at least, unfamiliar.
-
- I tried to use the pstat command on my RS6k (AIX 3.2) and I get the
- message
-
- "Cannot open dump file /dev/kmem"
-
- Now, I know that commands like ps and pstat are setgid kmem on Ultrix
- and SunOS too, but on AIX, what's going on? We have /etc/pstat linked
- to /usr/sbin/crash, with protections r-xr-xr-x. No setgid. Owned by
- bin, group bin.
-
- Then again, for /bin/ps, the protections are the same (owner and group
- are bin), but I have no problem doing a "ps gcu", or any other ps
- option.
-
- The weird thing is that I use pstat once in a while as a normal user
- (not as root) and I never encountered this before. Today I tried
- "pstat -T" as root and it ran with no problem.
-
- /dev/kmem has protections r--r----- and is owned by root, group
- system.
-
- What's going on? Is this something new to AIX 3.2? (I did an upgrade
- in June from 3.1.?)
-
-
- Thanks for any help,
