When a non-root user tries to use entstat, they get this message: “entstat: 0909-002 Unable to open device ent0, errno = 13”.

Also applies to ent1. Another machine, which should have a similar setup, does not have this problem.

So far the network has been working fine (nfs, telnet, ftp). With the rest working I might not care too much about entstat failing, but catia v4 needs it to run...

Looking in smitty and at lsdev, chdev, etc, I cannot see that there are any permissions that could be set on the device. The user and group structure is cloned from the other machine that works.

It is probably worth noting that the machine with this issue also has an issue creating the X0 socket with 700 permissions instead of 777, preventing non-root users from doing a graphical login until it is changed.

I tried truss with the entstat command, just see what I could see, but there was nothing understandable/obviously wrong that I could see, unlike the case with the X0 socket (which is how I diagnosed that issue).

Any ideas?

Thanks,

Does it definitely work as root? It's not a NIC that's part of an EtherChannel device?

Can you show us the output from lsdev -Cc adapter.

And ifconfig -a

(I should learn to think before hitting post message)

It isn't EtherChannel, nothing fancy on this server, it isn't really a server at all, just a workstation being used as one, and in sort of a minimal configuration at that.

Added a user to the system group in smitty and su'ed to him and tried it. Same error. And non-system-group users can run entstat on the other server.

Yeh, works for me here with a regular user (no additional groups).

It's definitely a permission issue, from errno.h

#define EACCES 13 /* Permission denied */

Oh hang on, entstat is setuid,

-r-sr-xr-x 1 root bin 30444 16 Jun 2008 /usr/sbin/entstat

is yours?

Thank you my good sir! That was indeed the problem.
I really should have thought to check the perms on that.

chmod 4555 and away we go!

Originally posted by: KellyClowers

Although there is still the question of why it wasn't...

Originally posted by: tony.evans

Usual reason is someone does a chmod -R somewhere they shouldn't and then fixes it the hard way but gets it wrong.

Does it go someway to explaining the other issue you have? i.e. has someone removed setuid's from other binaries causing obscure permissions issues?

Anyway, glad we got that one resolved.
