Password:
No shell

There are several possibilities. I am assuming that you are starting a session using telnet. The shell for the user broadvis is found with the command:

grep ^broadvis: /etc/passwd | awk -F : '{print $NF}'

Normally, this would be /usr/bin/sh which is the POSIX shell. If this is not correct, login as root and use the command vipw to edit the /etc/passwd file. However, if all users have the same error message, someone has probably changed the critical permissions of the / and /etc directories. These must never be changed. The permission and ownership should be:

drwxr-xr-x 29 root root 8192 Oct 8 18:41 //
dr-xr-xr-x 31 bin bin 8192 Jan 23 21:38 /etc/

No Shell means that the shell given to user is not available,

1. check /etc/passwd , as what shell is assigned to the user broadvis,

# cat /etc/passwd | grep broadvis

2. check that shell is there in the system and valid.

it may be caused by typo error during creation of the user and specifying a shell like /usr/sbin/vsh ,

Cheers,
Raj.

Hi lydi,

Yesterday one of my customer has same problem.I found that somebody has
changed the permissions of the / and /etc directories. After changing permissions problem solved. So its better to check permission as per "BILL" suggestion.

Hi Lydi

Pls check the ownership of the . in your problematic system. Hope the sysmptom is other than root user no one can login.

Do the following
#ls -latr
locate the . and check the ownership.
Did you do a vxrestore any thing in the / file sytem. This is potentailly dangeorus to do a restore in the /.
Or some one might have changed the permission of a "."

It should be root:root

TQ

You might want to use swverify on the system to see what else was changed. (There is a -F option to fix.)

Hi,

Make sure /usr and /usr/bin are both r-xr-xr-x.
