If you set the old hostname again via "hostnamectl set-hostname
sobolev.dsm.fordham.edu", can you still "start" X2Go connections? (Even if they
crash right away, that's separate issue.)

I think I'll have to just use the real system's name (returned via hostname)
instead of the short name to make all setups work without having to set the
short name to 127.0.0.1 manually.

Yes it works and the segfaults.
