No shell

Carlos G. Ramirez Cruz — Tue, 11 Feb 2003 15:13:41 GMT

Hello all,
I need you help, please.

I work with HP-UX 10.20, now any users can connect, the message "No shell" appears in all displays.

The files exist:

-r-xr-xr-x 2 bin bin 159744 Sep 3 1998 /usr/bin/ksh

-r-xr-xr-x 2 bin bin 499712 Oct 20 1998 /usr/bin/sh

-r-xr-xr-x 1 bin bin 155648 Dec 9 1998 /usr/bin/csh

-r-xr-xr-x 2 bin bin 159744 Sep 3 1998 /bin/ksh

thanks.

What shell are they attempting to use and does it appear in /etc/shells?

Hi:

Make sure that the '/usr' and '/usr/bin' directories allow read and execute permissions for everyone.

Regards!

Check if the user have a proper shell entry in /etc/passwd file (the last column).
Also check if the specified shell exists in /etc/shells

Make sure that permissions are least the following:

-r-sr-xr-x 1 root bin /bin/login (note the 's' bit)
-r-xr-xr-x 2 bin bin /bin/rsh
-r-xr-xr-x 2 bin bin /bin/sh
-r--r--r-- 1 root sys /etc/passwd
drwxr-xr-x 22 root root /

And make sure that the user has a valid shell in /etc/passwd

Shell errors can not only come from the shell itself, but /etc/passwd.

If the /etc/passwd does not have a proper shell, they will not be allowd to login. Normally I set the shell to /bin/$SHELL
where $SHELL is csh, ksh, or sh.

If root can not login or the system can not boot with the shell error, then check root's shell and ensure that /bin/sh is there and valid.

Shannon
