Fooling around with that now. The man page says that output is sent to the system log (which I presume is /var/log/syslog). It doesn't seem to be doing that. However, it runs through lots of ports (Not sure where it starts since I can't scroll up that far) and then reports: debug2: bind port 6999: Cannot assign requested address Failed to allocate internet-domain X11 display socket. debug1: x11_create_display_inet failed. So that at least explains why DISPLAY is not set. Any further help appreciated.
