Users cant telnet to my machine

bavondrake · 09-21-2007, 11:41 AM

Hi all,
I have set up a linux machine
#uname -a
Linux 2.6.5-7.244-smp #1 SMP Mon Dec 12 18:32:25 UTC 2005 x86_64 x86_64 x86_64 GNU/Linux

But users cant telnet to it.
This is the error message they get at their remote prompt
login: mytestuser
Password:
login: no shell: No such file or directory.

So i'm just wondering what is happening here because the account mytestuser exists ie /home/mytestuser and they are using default bash shell.

And when i issued this command su mytestuser as root i get

/root# su mytestuser
su: /bin/bsh: No such file or directory

Any idea of what is happening here?

thanks,

Bavon.

What distro are you using? Telnet is usually disabled by default because it's not terribly secure. It's generally recommended to use ssh instead.

The other thing is to look in /etc/passwd and see if the shell is set (find the row with the user name mytestuser and then look at the end, it should say something like /bin/bash).

Is that bsh a typo?

pljvaldez,
Thanks for the reply,i'm using SUSE LINUX Enterprise Server 9 (x86_64).
To the suprise there is no entry in /etc/passwd under the username mytestuser,but most users do have /bin/bash in their /etc/passwd entries .Could that be the reason it fail to login? If not how can i change a particular user login shell without changing the login shell for other?

the /bin/bsh is not a typo..it is bourne shell i think.And there is this /bin/bash for bourne again shell.

That's probably it. Just edit the /etc/passwd file as the root user and add your shell to the end of the mytestuser line.

Hmmm... on my system this is the description of /bin/bsh

BeanShell is a small, free, embeddable, Java source interpreter with
object scripting language features, written in Java. BeanShell executes
standard Java statements and expressions, in addition to obvious
scripting commands and syntax. BeanShell supports scripted objects as
simple method closures like those in Perl and JavaScript(tm).
You can use BeanShell interactively for Java experimentation and
debugging or as a simple scripting engine for your applications. In
short: BeanShell is a dynamically interpreted Java, plus some useful
stuff.

jay73 is right: there should be a typo somewhere on your system!

Yep, the original Bourne shell is sh, not bsh.
