invoking script from /etc/passwd

seeker333 · #1 (**permalink**) 04-24-2008

Hi all,

i'm a newbie trying to accomplish probably a not so difficult task.
on my system, if an ssh connenction terminates i launch a telnet to 127.0.0.1. I changed the shell (command) in /etc/passwd to invoke a script that just does this, "telnet 127.0.0.1".

my /etc/passwd looks like

Code:

root:x:0:0:root:/:/myScript.sh

and my script is like

Code:

#! /bin/sh
#myScript.sh
if [ "$TERM" != "" ]
then
telnet 127.0.0.1
else
<???>
fi

now on receiving a sftp connection, when the TERM is not set, i just want the effect to be same as

Code:

root:x:0:0:root:/:/bin/sh

how can i accomplish this? what do i need to do in place of <???> so that it works?

Thanks in advance.

Nothing, if you don't have any command after fi in your script, try this:

Code:

#!/bin/sh
#myScript.sh
if [ "$TERM" != "" ]; then
  telnet 127.0.0.1
fi

First of all, I do not understand why you are doing this, but:

Code:

#!/bin/sh
#myScript.sh
if [ "$TERM" != "" ]
then
   telnet 127.0.0.1
else
   /bin/sh $*
fi

That's because when you sftp to a server, "-c /path/to/sftp-server" args are passed to the shell...

Regards.
