I have a more worthy conundrum today. I set up a virtual network made up of eight virtual domains. Four were on 10.0.2.0/24, three were on 10.0.1.0/24, and one served as a router between the two networks. I am reasonably sure that I set up the network properly because ping, traceroute and tcpdump all showed appropriate results when used. However, for some reason, when I used nmap to scan a network (eg. nmap 10.0.2.0/24) some results would appear, then my workstation would reboot. I am completely puzzled by these events. Has anyone seen anything like this before or have any suggestions? I don''t have my ifconfig and route outputs at hand because the machine just rebooted, but I can replicate them tomorrow if anyone needs to see them. Any help would be greatly appreciated.

It would seem to be a large bug in the stable release of Xen. I set up my eight-domain virtual network again today, and I also connected the router to my (physical) workstation. Then, nmapping my workstation''s subnet from my workstation causes my machine to reboot - same story. I don''t understand why Xen is crashing like this...

I am using the stable release. I''m wasn''t using any options on nmap, I was using a command like this: nmap 192.168.103.0/24 nmap would give a couple results, then reboot my machine.

Hmm you''re probably right, I need to get my machine to boot first, then I''ll check and remedy the situation.
