Hi,
We finished testing LVS with a SIP simulator (sipp) now we started integrating
LVS with a SIP application server.
We used WebLogic SIP server.
Ldirecotrd's default SIP header didn't work with WebLogic, WebLogic sent the
200 OK reply to the wrong port.
I updated the SIP "Via" header line to fix the problem:
]# diff ldirectord ldirectord.org
3022c3021,3022
<
"Via: SIP/2.0/UDP $sip_s_addr_str;rport;branch=z9hG4bKhjhs8ass877\r\n" .
---
>
"Via: SIP/2.0/UDP $sip_s_addr_str:$sip_s_port;" .
>
"branch=z9hG4bKhjhs8ass877\r\n" .
You may want to add this change to the SIP howto.
Heartbeat loopback interface lost:
During our tests I noticed that after I restart heartbeat ifconfig loses the
loopback interface we setup for IP aliase.I can see the loopback interface when
I use the "ip add show" command but ifconfig no longer shows the loopback
interface.Is this a problem or is ifconfig confused?

Hi,
In fact I did read the SIP how-to before I send my email.
My SIP source distributes the traffic evenly per IP and port
pairs.
The SIP source is also aware of the SIP call ID so I don’t
need SIP call ID stickiness.
My main issue is the failback that doesn’t restore after the SIP service is
restored.
The balancing didn't work evenly when I used the wrr so I setup sh or dh.
Do the weight settings apply to sh and dh or only to wrr and
wlc?
Why is the default UDP timeout set to 300?
# ipvsadm -L --timeout
Timeout (tcp tcpfin
udp): 900 120 300
Does the load balancing mechanism direct traffic by IP only or
by IP & port paired?
Thx for your help,
Asher

have you read the LVS-HOWTO about
SIP?
