Send a File to Other System

[Soloam]

Hello, I need to retrieve the arp table from pfsense and send it to other system, my idea was to have a batch running "arp -a" and writing the output to a file that I would send to other system.

I think that I would prefere to push a file from pfSense so that I don't have to give ssh permissions to other users. The problem is where do I put the private key to give root the ability to scp to other system? Is this possible?

Another solution would be to publish the content in the pfSense webserver, but I would prefere to do that as a last resource so that I don't have the arp table open to all pc's on the network.

Thank You

You probably want a variation on this:

Never tried it myself but 30secs Googling turned up this likely suspect:

You should be able to get suitable command setup from that to write out the arp table to remote system directly I would have thought.

Edit: Tested. Mostly works. Should be adaptable to your needs.
