Beware! Use this with Caution – The below change will forward your private ssh-key to all servers that you connect to via SSH.
Firstly, create the following file with the below contents if it does not already exist on your system:
Host * ForwardAgent yes IdentityFile ~/.ssh/id_rsa
Set the correct permissions on the file:
chmod 600 ~/.ssh/config
Restart the openssh service for good measure..
service ssh restart
