X11 forwarding request failed on channel 0 mac

attempting to remedy my X11 forwarding request failed on channel 0 mac error I came across a great article on X11 forwarding on OS X

unfortunately when i tried to connect to my server, i still received the following error on my mac

X11 forwarding request failed on channel 0

best thing to do is use the -v command when you try to connect to your server.

ssh -X -v username@remote.server.name

it’ll give you hints as to why you’re still getting this error. what i got was:

debug1: channel 0: new [client-session]
debug1: Requesting no-more-sessions@openssh.com
debug1: Entering interactive session.
debug1: Requesting X11 forwarding with authentication spoofing.
debug1: Sending environment.
debug1: Remote: No xauth program; cannot forward with spoofing.
X11 forwarding request failed on channel 0

note the “Remote: No auth program” line.

all i had to do after that was install xauth on my remote server and it was all good. booyah!
