@mk @lnxw48 @kat this is interesting: I looked up the man page for ssh-copy-id, which mentions the -i parameter to specify the identity file, but it *doesn't* specify the -p parameter to specify the port; I used that anyway because I have setup SSH already to use a non-standard port - and it works :D
