You're not doing making an SSH connection for every file though -- you're making an SSH connection for every snapshot. Now, if you're taking snapshots every second, and each SSH connection takes on the order of .5 seconds, then you might have a problem. > So that I gave up that solution.

First, let's see if SSH connection establishment latency is a real problem. Second, you could adapt your Perl scripts to work over a persistent SSH connection, e.g., by using SSH port forwarding: % ssh -N -L 12345:localhost:56789 remote-host Now you have a persistent SSH connection to remote-host that forwards connections to localhost:12345 to port 56789 on remote-host. So now you can use your Perl scripts more securely.
