There is a mystery user on a remote systemWhat lastlog says?
.............. exists on pty/1 What about using lsof? lsof /dev/pts/*
Aha! There is no /dev/pts/1 but some piece of that connection still exists in memory somewhere. Solution: make another remote connection. This recreates /dev/pts/1. Now, follow that with a normal "exit" and it correctly tears down the connection and the mystery user disappears. Muchas gracias, Miguel. :m)
