Onderwerp: RE: CARP on 9.0 (was no subject)
How about:
%sudo netstat -s carp
...on both machines.
A few years ago I submitted (or maybe it was Steve Polyack) a patch to add
debugging to CARP, not sure if it ever got commited.

Also with a higer value like advskew 200 or 254 the role of the
servers stays the same.
Ok, there is something wrong so.
Did you check that the sysctl net.inet.carp.suppress_preempt is equal
to zero ? If yes, I don't have any more idea.

Hello
first off all thanks for your time.
sysctl -a | grep carp on both machines give me the following output

Here the advskew is set to 50, on the slave it is 20.
So the slave should be the master.
if i raise the advskew to 254, i see the change in the capture.
Both machines are fresh install with nothing changed on them so far just a
fresh build from a csup this morning.
And installed bash as the shell..
for freebsd-current@ the /etc/rc.conf file again
Master

ifconfig_carp0=vhid 1 advskew 10 pass letmepass 192.168.50.45 netmask

On the slave i have the following in /etc/rc.conf
ifconfig_bge0=inet 192.168.50.41 netmask 255.255.255.0
defaultrouter=192.168.50.150
