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!

That's what keychain is for. Any special reason to reinvent the wheel, instead of using standard cygwin packages?

sdesc: "An OpenSSH key manager"
ldesc: "Keychain is an OpenSSH key manager, typically run from
~/.bash_profile. When run, it will make sure ssh-agent is running; if
not, it will start ssh-agent. It will redirect ssh-agent's output to
~/.ssh-agent, so that cron jobs that need to use ssh-agent keys can
simply source this file and make the necessary passwordless ssh
connections. In addition, when keychain runs, it will check with
ssh-agent and make sure that the ssh RSA/DSA keys that you specified on
the keychain command line have actually been added to ssh-agent. If not,
you are prompted for the appropriate passphrases so that they can be
added by keychain."

If these descriptions weren't clear to you, any improvement to them are welcome.

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
