X11 forwarding request failed on channel 0
linux, ssh, x11-forwarding
Solution
Adding the `-v` option to ssh when trying to log in will give a lot of debug information which might give a clue to exactly what the problem is, like for instance
debug1: Remote: No xauth program; cannot forward with spoofing.
which in my case installing xauth on the server fixed the issue.
Problem
When I do "`ssh -X abcserver`", I got message "`X11 forwarding request failed on channel 0`". I checked online and it was suggested to solve it by switching "`X11UseLocalhost no`" to "`X11UseLocalhost yes`". However, both my manager and I don't have this administrative privilege. I am wondering, except this solution, whether there is another option to solve the issue ? I also don't have `sudo` privilege to directly install `X11` on the server.
