4.1.1 crashing 🔗 link

I'm not sure how I have managed to crash bbnet but I have ;)

2005-09-09 14:13:56 Execution of '/usr/sbin/fping -Ae' failed with error-code 99
2005-09-09 14:13:56 fping invocation failed: Permission denied

(I fixed the fping problem)

bb-hosts had 2 devices (server and one client).  I added a 3rd device to do dns testing and I crashed the network testing.

CentOS 4 box:
Linux <linux_box> 2.6.9-5.0.3.ELsmp #1 SMP Sat Feb 19 19:38:02 CST 2005 i686 i686 i386 GNU/Linux

[hobbit at linux server]$ pwd
/home/hobbit/server
[hobbit at linux server]$ ls -l core*

I compiled hobbit on this box today.

Looks like a problem with the C-ARES library that Hobbit uses for
DNS lookups - the trace is identical to one I've seen before.

If you run bbtest-net with the "--no-ares" option, I'll bet that
it works OK.


This is hopefully fixed in the next C-ARES version. If you want to try
that, you can pick up the latest Hobbit snapshot - build it and you can
just copy the bbnet/bbtest-net binary on top of your current
installation.


Henrik

Yes, the --no-ares did the trick.

Thanks
