Emacs + TRAMP working with Krypton #252

Closed cro closed 5 years ago

cro commented 5 years ago

I am an Emacs user and have switched to Krypton for my ssh key needs. Since I have done so I am no longer able to get Emacs's TRAMP remote file and shell capabilities working. I suspect it is because of Krypton's console messages. Is there some way to turn them off, ideally just for my Emacs instance?

Closing, further investigation revealed problems with my .bashrc. Sorry for the false alarm.

Realizing that some folks find answers to their questions in the strangest places, I will post my solution here.

My issue was that I had installed Byobu (the screen / tmux manager) on several remote servers at the same time I had enabled Krypton authentication. Since other one-off commands like ssh <remote-server> ls worked fine, I did not suspect Byobu had broken TRAMP. What I did not realize was that TRAMP and eshell behave like interactive logins. The Emacs TRAMP manual (https://www.gnu.org/software/tramp/#Remote-programs) mentioned that TRAMP sets $TERM to dumb when logging into remote machines, so adding a conditional that does not start Byobu when $TERM=dumb took care of the problem.
