passwd behavior changed / not working

[amitcent_26]

Hi Guys,

I am running into a weird issue. I created an user (Using useradd / adduser). Trying to set password for it using passwd, which does nothing but just bring it to root.

[root@servername ~]# passwd ravi
[root@servername root]#

This is even happening while being on root, when I type passwd and enter from root prompt, it should ask to change password, but it goes like -
[root@servername ~]# passwd
[root@servername root]#

Can somebody please help to identify the issue ?


thanks,
Amit

What do you get with which passwd ? Does rpm --verify passwd output something? Normally it should not output anything. Are you the only user who has root access on that system, ie. is it possible that someone else has screwed something up?

Also try /bin/passwd to make sure it's running the correct thing

Thanks for responding man !
There r a few other who have su to root access, I doubt too that someone has screwed something up.

So output of which passwd

[root@servername ~]# which passwd
/bin/passwd


and output of rpm --verify passwd

[root@servername ~]# rpm --verify passwd
.......T. c /etc/pam.d/passwd
..5....T. /usr/bin/passwd
[root@servername ~]#

Can we do a yum install passwd, will it overwrite any existing file (user/passwords) or just install new binaries ?

Hi -

output of /bin/passwd

[root@servername ~]# /bin/passwd
[root@servername root]#

Its really weird

[TrevorH]

..5....T. /usr/bin/passwd

So the md5sum and timestamp of the /bin/passwd file does not match what rpm expects. I'd be suspicious about now but check the file and see what its content is - perhaps someone did something silly and meant to pipe into /bin/passwd but redirected on top of it instead. Or maybe it's more serious.

If it's the trivial "someone with root overwrote it by mistake" then yum reinstall passwd will fix it. If it's not trivial, break out the backups and start the reinstall...
