[PLUG] exchanging files on LAN

[Louis Kowolowski]

Adding to what Paul said,

you should also be able to run ’ssh-add -l’ on the destination host and see the same key. If not, you aren’t successfully forwarding the agent.
You may wish to try things manually, with a ssh -A ${host}, alternatively, you could add ' ForwardAgent yes’ to your .ssh/config under a host stanza (perhaps the ‘Host *’). This would cause the agent information to be automagically forwarded even if you don’t use the -A option.

Apparently not. Since all transfers are in the LAN and not exposed to the outside world, which tool allows internal scp and ssh transfers without entering the pass phrase each time? I no longer remember what it is and missed finding it looking at ssh web pages.
