Hi,
I'm having an issue with = relayd on a freebsd 8.2
I'm trying to create a lo= adbalancer for dns following example 4 on
this page:
[1]https://calomel.org/relayd.html ( I did modify the servers= to be
the correct one I have)
I installed relayd from ports a= nd did a make install clean
distclean.
I have created a rule that forw= ards dns traffic to port 8053 and it
works.
The problem is when using the d= ns protocol relayd crashes with a
signal 11 when it gets a request.
Removing the dns protocol and t= hereby makes relayd to listen on tcp
works like a charm. And it doesn'= ;t crash.
The uname -a gives the fo= llowing:
FreeBSD traficman.csis.local 8.= 2-RELEASE FreeBSD 8.2-RELEASE #0: Thu
Feb 17 02:41:51 UTC 2011 &= nbsp;
[email protected]:/usr/obj/usr/src/sys/GENERIC a= md64
It's a virtual machine ru= nning on a KVM though QEMU (or so I'm
told.)
I have attached a text file con= taining the lines in the messages log
as well as truss output from the proc= esses when crashing.
It's my hope that you eit= her can give me a quick fix or at least
tell me to give it up. J
M= ed venlig hilsen / Kind regards
