Maybe a stupid question ...
I added the --trace option to the bbtest-net and it uses standard traceroute. When I try to stop hobbit that traceroute (to a host that's down for the moment) keeps living. I remember some post where someone mentioned that it's more interesting to use mtr instead of the standard traceroute for obvious performance reasons. Could this be the cause of my problem as well ? How would i make hobbit use mtr instead of traceroute ?

Hello Henrik,
I see alot of following errors in my bb-network.log:
2005-01-24 08:19:44 WARNING: Runtime 477 longer than time limit (300) 2005-01-24 08:20:14 dns_queue_run deadlock - loops=834
There is some sort of problem with your DNS lookups, causing them to timeout. Check if your /etc/resolv.conf points at the correct DNS servers and that they actually do respond to lookups - e.g. pick some of the hostnames from your bb-hosts file and try to run a "nslookup HOST" on them.
I have one report that the ARES library used by bbtest-net does not work properly with some DNS servers. So you could try adding the "--no-ares" option to the bbtest-net command in hobbitlaunch.cfg. If that makes the problem go away, I'd like to know a bit more about your DNS server setup - like what kind of DNS servers are you querying?
Regards, Henrik

I don't think it's the cause of your DNS problems - they are separate.
The command that bbtest-net runs to do a traceroute is determined by the TRACEROUTE environment variable. So you can set this up in ~/server/etc/hobbitserver.cfg, there is an example in the hobbitserver.cfg man-page.

I am new to the list, so sorry if this has been covered. I know the Hobbit info says it only runs on Un*x type OS's, but I was wondering if there was any way to get it compiled and running under Cygwin or something similar? I would like to get it up and running for my LAN at home, but I only have Windows machines.
Thanks, Martin Parrott

Feel free to attempt it, but I'm fairly sure it will not work. Hobbit uses a *lot* of very Unix-ish stuff: Pipes, semaphores, shared-memory, signals ... I would be surprised if Cygwin was up to running it.
Your best bet is to dig up some old, unused PC and put Linux on it. Hobbit doesn't require the speediest of hardware to handle a small LAN, so I think that's the easier path to take.
