[lug] neat little ssh trick

[dan radom]

I've been using ssh hostkey authentication for a while now, and I've always wanted a way to make cron aware of my running ssh-agent for passwordless scp action from cron.  Here's how I've made that work...


lunar:~$ grep ssh-agent .xinitrc
ssh-agent -s &> $HOME/tmp/sshagent-vars.sh && . $HOME/tmp/sshagent-vars.sh

lunar:~$ cat tmp/sshagent-vars.sh 
SSH_AUTH_SOCK=/tmp/ssh-XXui8WMv/agent.22994; export SSH_AUTH_SOCK;
SSH_AGENT_PID=22995; export SSH_AGENT_PID;
echo Agent pid 22995;


Now I just do things like ...

#!/bin/sh
source /home/graffix/tmp/sshagent-vars.sh

rsync -avz -e ssh --delete --exclude "bin/" --exclude "icons/" --exclude "include/" --exclude "man/" --exclude "proxy/" mars:/storage/apache/ /home/graffix/backup/html


Enjoy,
