passwd command hangs when trying to change password.

[rob nolen]

Hello,

I am trying to change the password for a user on my 11iv2 box. When I type passwd , my shell just hangs... doesn't do anything at all. I have to ctrl-c to get back to a prompt.

Anyone ever experience this before?

The first thing that I would do is "type passwd" to determine if you are running the "real" passwd command. You could be running a Trojan Horse.

/usr/bin/passwd.

In sam, I can change passwords fine.

If I just type passwd to change password for root, pops right up and asks me for the new password.

could you tell a bit more about your system, trusted? shadow passwd file? nis?

Best regards,

Try running pwck to look for problems with your password file.

Is this an NIS user account you are trying to change?

Is this a trusted system?

[Bill Hassell]

Or do you have NIS for passwords? Hangs are often related to networking problems.

[rob nolen]

Sorry for the lack of detail.

We are not running shadow, no NIS, and not a trusted system.

All accounts are local to this machine, and we aren't doing anything over the network.

One of the big differences when you run passwd as root is that you are probably running /sbin/passwd rather than /usr/bin/passwd. By any chance, have you "improved" the security of your system and cleared the setuid bit on /usr/bin/passwd? Also, do a bdf and make sure that there are no full filesystems -- especially /var and /.

[rob nolen]

Funny. When I run /sbin/passwd it works fine. Suid bit is still on /usr/sbin/passwd.

Also, filesystems have plenty of free space.
