So, i guess to answer some of my own questions, yes, i should have the =
same wackamole.conf for each box with the VIP the same for both. The =
Changelog reference in 1.2.0 was referring to having more real machines =
than VIPs by setting VIP to 0.0.0.0 on some of them. Must have been =
changed in 2.0.0. Oh, well. The core dump is still perdicatably =
happening. I am working around it as mentioned below. So, my other =
question is that on one of the machines the failover is not working to =
well. It keep getting these messages in var log messages. I assump the =
connect failed and Illegal session are bad. I'm going to be a total jerk =
and cross post since it is awfully quiet around here:

Subject: [Wackamole-users] wackamole core dump
i would like to setup wackamole as a simple failover mechanism for a =
stateless web server running linux 2.2.16.
the web servers have IP addresses 192.168.0.1 and 192.168.0.2 =
respectively
i setup the following wackmole.conf on each:
=20
Spread =3D 4803
SpreadRetryInterval =3D 5s
Group =3D wack1
Control =3D /var/run/wack.it
Prefer None
VirtualInterfaces {
{ eth0:10.1.1.2/32 }
}
Arp-Cache =3D 90s
Notify {
eth0:10.1.1.5/32
eth0:10.1.1.4/32
eth0:10.1.1.6/32
eth0:192.168.0.0/24 throttle 128
arp-cache
}
balance {
AcquisitionsPerRound =3D all
interval =3D 4s
}
mature =3D 5s
=20
My first question is -- would that suffice for a failover scenario, or =
should the .2 backup web server have a virtual interface of =
eth0:0.0.0.0/32 (as per a change log i read)?
This of course is all theoretical since my real problem seems to be =
that wackamole seg faults when i try to start it. If i create a =
secondary interface (eth2 for eg) change references to eth2 for virtual =
interface it does not core dump. I can attach the core if you are =
interested, but it is 7.6megs...
spread seems to run fine (according to spmonitor and spuser passes =
messages back and forth), although i do start it with a spread -n =
hostname.
thx for your time.
