passwd not working ..

someone_4 — Fri, 10 Aug 2001 19:53:34 GMT

Hello
We are trying to change the password on an HPUX 11.0 box.
when you do in a box that works we get this:
#passwd
Changing password for root
In the box we have trouble with we get this:
#passwd
#
we get the promt right back. We we try to do it though sam. we get this:
Executing passwd(1) command to set password for user root

Press to continue sam...

and we hit return and go back to sam.
Anyone have any ideas?

Hi Richard:

You might trying logging out and then back in to resource your $HOME/.profile and correct any terminal settings.

BTW, you have additional information provided in your 'rm' post (if you haven't already seen it.

Hi Richard:

On the trouble box, since you seem to be logged in as root (judging from the '#' prompt), whatever you do don't logout.

Do a pwck to check the status of the passwd file. It appears to be corrupt or you may have a full filesystem. Do a bdf.

One fairly simple fix is to copy /etc/passwd on the bad box to /etc/passwd.sav and then replace it with a passwd file from another box.

But make sure that you attempt to login as root from another session so that you don't kill your working root session.

This is really weird now.
Its more then a password issue.
ll does not work
bdf works
lsf does not work
ls -f works
pwck returns the promt
and we dont have any full file systems.

Hi Clay:

Darn good point! I'm so used to keeping two root sessions open (or opening a second whenever I mess with the passwd file) that I forgot to mention that!

Hi

i had more or less the same problem , the problem was with the primission of the dir. and the files that had the problem .

so my advise is to check the /sbin and /usr with a diff computer but the best thing is to restore from a ignite or to do a new cold install but i solve it but changing the rigth primission .

good luck

Hi Richard,

You say ls -f works and lsf does not work; that is strange. lsf and ls are the same file with hard links between them - as long as we are talking about the /usr/bin/ versions. However, there is no /sbin/lsf (just /sbin/ls).

I would say that /usr has become unmounted excepted that pwck is normally found in /usr/bin. Make sure the /usr is mounted.

Have you by any chance applied patches that would have replaced any shared libraries?

I somehow feel that we are overlooking the obvious.

Yeah James, I sort of felt I needed to scream the warning before it was too late.

But passwd does not work from anywhere.

Hi Richard & Clay:

I agree this is strange. "pwck' is in /usr/sbin. But still things don't quite match expectations.

Take a look at your /usr/bin & /usr/sbin directories. Make sure they are 'bin:bin' and "555" (r-xr-xr-x).

Yet another thought is transition links. Make sure (off of /) you see:

lr-xr-xr-t bin -> /usr/bin
lr-xr-xr-t lib -> /usr/lib

someone_4 — Fri, 10 Aug 2001 20:45:59 GMT

Ok the permissions are right
but how can I check
lr-xr-xr-t bin -> /usr/bin
lr-xr-xr-t lib -> /usr/lib
if I cant do ll from / ?

Hi Richard:

Try absolute path :

# /sbin/ls
# /usr/bin/ls

My bet is /sbin/ls will get you there.

...got to run home, hope Clay is still on...good luck; we will solve this, yet!...

Hi Richard,

I know the Royalties are trying to help but since the problem is unresolved.

since you said /sbin/ls is working .

try
1. /sbin/ls -ald /
Make sure its permissions are 755(rwxr-xr-x) and owned by root:root
2. /sbin/ls -ald /bin->/usr/bin
should be lr-xr-xr-xt
3. /sbin/ls -ald /lib
should be lr-xr-xr-xt /lib->/usr/lib

btw did you check if /usr was mounted?

Re: passwd not working ..

linuxfan — Fri, 10 Aug 2001 21:57:33 GMT

Hi Richard,

forget the last post, /usr must obviously be mounted because you are able to execute files in /usr/sbin and /usr/bin.
sorry my fingers were typing faster than my mind was thinking. :-)

Hi Richard,

What do you mean with 'll does not work' ? Do you mean it hangs ? The reason that it hangs in / could be that there is something wrong with an NFS mount or a mounted CD. In this case ls will work but ll will not. What you can do to find out on which dir or mountpoint it hangs do the following:
for i in `ls`
do
ll $i
done

It will hang at the dir which gives you the trouble. You can then try to umount it.

BTW, are you using NIS ?

Hey Mark it did have to do with an NFS mount. I opened a call with HP friday night. I will post the notes of that call on monday.

Hi Richard:

Well, now this makes a bit more sense. Great call, Mark!!!

A word to the wise, Richard, if your 'pfs_mount' a CD. Always follow the order for starting and stopping the 'pfs_mount' daemons. Failure to follow the prescribed order, or capriciously killing one of the daemons, will lead to a system that progressively uses more and more CPU time and slowly becomes catatonic. One symptom, in this case is a hanging 'ls' and a handing 'bdf'.

Please post the additional details you are offering. Thanks!

Regards!
