id doesn't show user name

Supporto Unix — Fri, 15 Nov 2002 16:08:43 GMT

hi,
on a 11.11 host, the output of id command doesn't show user name :
[hostname]/# id
uid=0() gid=3(sys) groups=0(root)
[h3mih108]/#
**************************************
[hostname]/# id -un

[hostname]/#
**************************************
[hostname]/# id bin
uid=2() gid=2(bin)
[hostname]/#

Has anyone a suggestion?

thanks in advance

Luigi

Hi,

The 'id' command uses the 'logname' command, which calls the 'getlogname' function, which reads it from /etc/utmp. So maybe it is a permissions problem on /etc/utmp?

Luigi,

My 11.11 L-class shows:

root# uname -a
HP-UX manitoba B.11.11 U 9000/800 165901597 unlimited-user license
root# id
uid=0(root) gid=3(sys) groups=20(support),5(daemon),1(other),6(mail),22(sna),4(a
dm),2(bin),7(lp),10(tty),0(root)
root# id -un
root

What's your patch level?

Have you checked the permissions for /etc/passwd and /etc/group?

You you have pseudo root accounts (UID=0)? Multiple accounts with the same UID are not supported. You can experience problems with who, finger, and id if you have multiple accounts with the same UID.

Has root's entry in /etc/passwd been removed? That's one possibility.

Don't logout as root before you verify there's a superuser account in /etc/passwd.

Re-read your post. If my theory is correct then the entry for bin has been removed also.

hi,

This message means that your /etc/passwd file is corrupted. Try a pwck.

Someone suggests me to do the following things:

Your ll output shows the uid is not being resolved. Same symptom as the id output.

Have you verified root's passwd entry?

All indications are that something's wrong with /etc/passwd.

The problem is that /var is full. Never let /var become full. It causes all sorts of nasty problems.

You need to make space in /var (either delete files or add space). You will have to do a reboot to clear up your problems.

I had the same problem not so long ago.
Please do pwck . I have discovered a blank line at the and /etc/passwd and a couple of other things. Fix your /etc/passwd first.
Hope that helps.

Dimitry.

Is your problem related to the problem stated below? if yes follow the steps below.

Problem Description

I receive the following output
when I use the id command on a slave
YP server:

uid=112()

The user name is not appearing between
the parenthesis as expected.

The command does return the proper output,
however, when run on the master YP server.

What can I do to resolve this?

Configuration Info

Operating System - HP-UX
Version - 10.20
Hardware System - HP 9000
Series - K420

Solution

We recommend that you re-initialize the
slave server with ypinit -s to
correct this problem.
