ssh keychain for git pull cron

I am a bit of a newbie with linux, so must apologize straight away if this is something obvious and/or silly.

I am trying to create a git pull cronjob that gets update from GitHub repo every few minutes.

Now the problem is that I can not get it working without entering pass-phrase every time cron runs.

ssh-agent and ssh-add does not do the trick as they loose the passwords every time user logs out. So I got the guide http://www.cyberciti.biz/faq/ssh-passwordless-login-with-keychain-for-scripts/ and followed it, but still no results.

I can not seem to get the keychain working properly. I think.

The steps I have done:

• Installed the keychain from RPMforge.

• Edited the vi $HOME/.bash_profile to include:

  /usr/bin/keychain $HOME/.ssh/id_rsa

  source $HOME/.keychain/$HOSTNAME-sh

• And according to the guide, after I re-log, keychain should be working and I should not need to enter the pass-phrase every time I ssh -T [email protected]

I am probably missing something, but can not seem to figure out what. Maybe someone has some suggestions ?
