There are quite a lot of ways to do that. You could NFS-export then files and then use a tool to copy them on the other box locally (tar, cpio, cpdup, whatever). You could run an FTP server and then use one of the various FTP mirror tools to copy the files (e.g. ports/ftp/omi). You could use plain old rcp. You could apply this (trivial) patch that adds support for cipher "none" in ssh and scp: http://www.secnetix.de/olli/FreeBSD/patches/openssh-cipher-none The advantage of using scp (with "-c none") is that you can use all of the ssh features, such as key authentication, server aliases (via ~/.ssh/config) etc. You can also use other file copy tools (such as cpdup) that can be tunneled through ssh.
