The most secure thing you can do is leave the service off and start it only when you need it. Unless you're extremely paranoid you can use any service you want to transfer the data. Just shut the service down once the transfer is complete. I use NFS shares for that type of thing. If you want to do this remotely, use ssh to log in to your server and start/stop the service. ----- Original message ----- From: "jim scott" <jimdscott at gmail.com> To: "TCLug List" <tclug-list at mn-linux.org> Date: Mon, 30 Jan 2006 10:29:50 -0600 Subject: [tclug-list] Simplest home network possible Hello, all. I'm going to connect up 2 Linux boxes on a home network. I'll connect the boxes and my DSL router/modem to a switch. Right now, I've got all incoming services disabled on both computers -- no telnet, no ftp, no rsh. I would like to be able to copy data from one PC to the other. What's the most secure service I can use for occasional data transfer between the two PCs? Thanks for any advice.
