Hello,
I am using ipvsadm v1.26 2008/5/15 (compiled with popt and IPVS v1.2.1) on
a Ubuntu server with kernel 3.5.0-17-generic on a x86_64 platform
I have the following network config
eth0 Link encap:Ethernet HWaddr 00:0c:29:d7:cd:a6
inet addr:192.168.49.16 Bcast:192.168.49.255 Mask:255.255.255.0
And using the following ipvsadm config
-A -u ubuntusrv.localdomain:sip -s rr -p 40 pe sip
-a -u ubuntusrv.localdomain:sip -r 192.168.49.7:sip -m -w 1
-a -u ubuntusrv.localdomain:sip -r 192.168.49.17:sip -m -w 1
When I make a sip call to 192.168.49.16 (ubuntusrv.localdomain), I see the
following 2 connections being set up
ipvsadm -Lcn --persistent-conn
IPVS connection entries
pro expire state source virtual destination
pe name pe_data
UDP 00:49 UDP 172.29.9.35:0 192.168.49.16:5060
192.168.49.7:5060 sip
43D826387A240B39D11C000BCB4977CE19396@xxxxxxxxxxx
UDP 04:41 UDP 172.29.9.35:5060 192.168.49.16:5060
192.168.49.7:5060
Apparently because of the 2nd entry in the table
UDP 04:41 UDP 172.29.9.35:5060 192.168.49.16:5060
192.168.49.7:5060
All my successive calls to 192.168.49.16 are going to the same real server,
although the sip call id is different.
Since I am using Round Robin scheduler, I would have expected every call to
go to another real server.
How come this plain UDP entry is created? I would have expected only the
entry with the sip pe data
Thanks
Yaron
