ssh -X not working?

Weird error. It worked two weeks ago just fine.

Code:

bill@Durandal:~∰∂ ssh -X bill@dubslow.tk

I would get rid of *** System restart required *** by rebooting for starters. I assume you just installed a minor kernel update.

Yeah, but it's kind of a pain and I'm moving out tomorrow anyways, so I'll do that then. Why would that help in any case?

It has to do with security. You can either mess with 'xauth' and/or 'xhost' or you can temporarily disable the security by using -Y (trusted) instead of -X (untrusted). Only ever use -Y to connect to a machine that you trust. Anyone with root on the target machine can take control of and/or sniff the connection.

And yes, when your system says to reboot, you probably should. :)
