But maybe the network connection was just interrupted and it'll be
back in a few minutes? Since my home internet via mobile broadband
is unreliable that often happens during SSH sessions. I can come
back in 15min and my SSH terminals are all working again after the
signal came back (well, not always, but sometimes). Mosh, which
uses UDP, handles that better though.
