Hi,

I have some problems to do asterisk load balancing with Ultramonkey.
I am trying to do asterisk (http://www.asterisk.org) load balancing with SIP
protocol.
The topology used is streamline high availability and load balancing (
http://www.ultramonkey.org/3/topologies/sl-ha-lb-eg.html) i.e 2 linux
directors / real servers.
The OS I used for both directors / servers is Ubuntu 8.04 .Then I use
configuration exactly as it is presented in the example except for node name
and some changes.

Since I am using SIP, I add the following lines to ldirectord.cf file

*checktimeout=10
checkinterval=2
autoreload=no
quiescent=yes
logfile="/var/log/ldirectord.log"

virtual=192.168.6.240:5060 gate
  real=192.168.6.2:5060 gate
  real=192.168.6.3:5060 gate
  service=sip
  scheduler=rr
  persistent=600
  protocol=udp
  checktype=connect*

After all files are already configured, I stop the ldirectord and start
heartbeat as instructed. I check the master linux-director and says that
master running in server 1 (192.168.6.2) and master stopped in server 2
(192.168.6.3). Then I try to stop the heartbeat in server 1, the server 2
becomes the master. So in general, the heartbeat and ldirectord is working
theoretically.

Then, I restart both of my servers (server 1 becomes the master again) and
start asterisk service for both servers. After that, a client PC with an IP
of 192.168.6.101 is configured using X-Lite softphone to connect server
192.168.6.240. Server 1 (with IP 192.168.6.2 which assumes the role of
Virtual IP address 192.168.6.240) detect this and the X-Lite shows status
ready. This can be verified using command (you need asterisk installed to
verify this) :

*asterisk
asterisk - r
*CLI> sip show peers*

Then I try to test failover and entirely shutdown the Server 1. Then Server
2 assumes the master status theoretically (verified by using command
*/etc/ha.d/resource.d/LVSSyncDaemonSwap
master status*).

However, the real failover doesn't occur. When the client try to connect
192.168.6.240, it seems it can't find the asterisk service that is running
at 192.168.6.240. However when I ping both 192.168.6.240 and 192.168.6.3,
both server show respond.

Then I configure the X-Lite softphone to connect server 192.168.6.3. And it
shows connected. But it doesn't happen that way when I connect to
192.168.6.240

My question is why after the failure of server 1, asterisk at server 2 can't
assume server role? Theoretically, when the softphone try to connect to
192.168.6.240, asterisk at server 2 should detect this. Can someone give
tips of what should be done to make this right? Anyone has an experience
with this? Thank you.

Best Regards,
Kurt Weasel.
