failover slave doesn't send gratuitous arp

Hi folks,

I was hoping you could assist me in solving a problem.  I'm configuring
two failover servers following the guidelines for a High Availability: Single
Virtual Service (see http://www.ultramonkey.org/3/topologies/ha-eg.html
).

My system is running CentOS release 4.3 (Final) ( 2.6.9-34.ELsmp #1 SMP Wed Mar
8 00:27:03 CST 2006 i686 i686 i386 GNU/Linux)

I have connected a crossover cable between the servers on eth1.  

My ha.cf file on both servers looks like:

debugfile /var/log/ha-debug
logfile /var/log/ha-log
logfacility     local0
keepalive 2
deadtime 30
warntime 10
udpport 694
initdead 120
udp     eth1            # Linux
auto_failback off
node    master.mydomain.com
node    slave.mydomain.com
debug 1

My haresources on both nodes looks like:

master.mydomain.com  \
        IPaddr2::xxx.xxx.xx.xxx/21/eth0/xxx.xxx.xx.xx vsftpd

I then start hearbeat (service heartbeat start) on the slave
and then the master.  I notice that a gratuitous arp goes out
from each of the servers as the service starts.  Since I start
my master last, the arp tables contain the MAC address for this
node and ftp works.

However, when I test failover by stopping (service heartbeat
stop or /etc/init.d/heartbeat stop) on the master node, the slave
does not send out a gratuitous arp.

Since these machine sit on the DMZ of a FW, none of my machines
can reach it until the FW arp cache clears.  Which, right now,
is set for 4 hours.  I did set the FW cache timeout to 5 minutes
which worked but I rather not change my FW.

Likewise, I have a few machines sitting on the same LAN as the
failover pair and I have to wait a couple minutes before the 
workstation arp cache clears before I can connect to the slave
server.

If I send out (by hand) a gratuitous arp via:

/usr/lib/heartbeat/send_arp -i 200 -r 5 -p
/var/lib/heartbeat/rsctmp/send_arp/send_arp-xxx.xxx.xx.xxx eth0 xxx.xxx.xx.xxx
auto xxx.xxx.xx.xxx fffffff
fffff

on the slave machine.  the LAN workstations and the FW update and all
works great!  However, I can't seem to figure out how to force this 
when the slave senses the heartbeat failure of the master.

NOTE:  the X'x in the above IP addresses are of course the ip of the 
       virtual interface that gets created on eth0:0 which is separate
       from the ip's on eth0 and eth1.

Any suggestions/advice would be grately appreciated!

Cheers,

Janet


P.S.  This is a second post of this.  Don't think the first one made it into
      the forum.
