I love ssh-agent, but always found that running source ~/.ssh.agent annoyed me!
That was before I wrote this code, which I absolutely love:
source ~/.ssh.agent PID=$SSH_AGENT_PID if [ -f /proc/$SSH_AGENT_PID/cmdline ]; then CMD=`cat /proc/$SSH_AGENT_PID/cmdline`; if [ "$CMD" != "ssh-agent" ] ; then PID=0 fi else PID=0 fi; if [ "$PID" -eq 0 ]; then ssh-agent > ~/.ssh.agent source ~/.ssh.agent ssh-add fi;
Put simply, when added to your .bash_profile this code will ensure that your current ssh-agent is loaded. You may now ssh freely into servers without always typing that 100 character SSH Key password
