Somewhere in my notes I have the how to for opening up a shell and doing server to server transfers.
It's something like
[
ftp://[user[:password]@]host[:port]/path[/]] | -u [
ftp://[user[:password]@]host[:port]/path[/]]
I haven't done it in years so I don't remember the exact syntax. I guess man ftp would be a good place to start, lol.
