I’m using SSH keys, and control sockets, actually. I’m just always looking for more “efficient” ways to do things! :)

Good point on potential memory usage for zmodem, I hadn’t thought of that.

The scp example you present is straightforward for sure, but it gets a bit more dodgy if the pathname is long.

Why are you logging in again instead of using ssh keys? If you’re worried about the overhead of an additional connection, you can consider using Control sockets in ssh (options ControlMaster and ControlPath in ssh/config).

This is neat, but just horrid for memory if screen doesn’t queue the zmodem contents to disk prior to dumping it out. It’s also more work than just typing scp foo@y:file .

Why should I have to log in again? If ssh understood zmodem, I could make file transfers without having to make any new connections.

I usually end up using lftp for file transfers over ssh, it just bugs me that I have to fire up another program.

There’s got to be something I’m not understanding about this – why aren’t you just using scp? Is figuring out the source/remote thing tricky? Or the login a hassle? I have a doskey macro for this whenever I want to upload anything to my webhost (using pscp, naturally).

I think this is very cool!
