Sometime in May Ghataora, Hardeep assaulted the keyboard and produced:

| Do you get any useful information when you 'ssh -X -vv -X user at B' ?
| I think I had this problem on FreeBSD and there was something in the -vv
| output relating to it calling an application along the wrong path, I
| *think* it was the xauthority stuff.

this is the output:

 liberty and democracy?
