For convenience you can also try that comes

Greate snippets, thanks ! Also you can use the following command to convert "Putty-style" public key to "Open SSH" style

ssh-keygen -i -f >

Very useful. Had to comment out the mkdir and touch at lines 39 and 40 because my server already has those but otherwise does what it says. Excellente!

@ferielboa: just copy this text and save it as Then, from the folder where you saved it call python ceilfors@my-remote-machine. You can also add a custom port for the ssh/scp connection in my fork with the -p flag. It will ask you to login twice, once for the scp and once for the ssh connection.
