ssh with one agent for all bash´s


-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

Hi,

looking up the mailinglist and testing a while I figured out that with
following .bash_profile, I can have one ssh-agent thruoghout all sessions I
open!
Once the agent is running the following shells use it again!

Although the first shell will not close by it self till the last one is
gone.
May be helpfull for anybody using ssh!

#!/bin/bash
trap '
    if [ "$(ps -fu `id -un`|grep -c bash)" -eq 2 ]
    then
        test -n "$SSH_AGENT_PID" && eval `ssh-agent -k` ;
        setx.exe SSH_AGENT_PID "";
        setx.exe SSH_AUTH_SOCK "";
    fi
' 0

...

if [ "$SSH_AUTH_SOCK" = "" ]
then
    eval `ssh-agent`;
    /usr/bin/tty > /dev/null && ssh-add $HOME/.ssh/id_dsa;
    setx.exe SSH_AGENT_PID $SSH_AGENT_PID;
    setx.exe SSH_AUTH_SOCK $SSH_AUTH_SOCK;
fi
