RE: [OpenSER-Users] lookup problem - sr-users

16 Jul 2007

Hi,

I will try to give more details,
Actually everything was working fine till I the day I moved my dns server to the same
machine with ser. I setup bind9 on the machine where ser is installed. I did the same dns
configuration with the old one but after some time ser started to give that error. I then
removed bind9 but nothing changed. 

Now here is my named.conf
**********************
zone "intersan.com.tr" { type master; file
"/var/cache/bind/intersan.com.tr.hosts"; };zone "sahratelekom.com.tr"
{ type master; file "/var/cache/bind/sahratelekom.com.tr.hosts"; };
**********************
this is "intersan.com.tr.hosts":

When I listen the main interface, here is the traffic

85.105.26.49:17030 -> 85.111.0.205:5060INVITE

85.111.0.205:5060 -> 85.105.26.49:17030
SIP/2.0 100 Giving a try

85.111.0.205:5060 -> 85.105.26.49:17030
SIP/2.0 513 Message too big

85.105.26.49:17030 -> 85.111.0.205:5060ACK

The loopback interface traffic is:

85.111.0.205:5060 -> 85.111.0.205:5060
INVITE
85.111.0.205:5060 -> 85.111.0.205:5060
SIP/2.0 100 Giving a try
--INVITE and Giving a try repeated 5 times--

85.111.0.205:5060 -> 85.111.0.205:5060
SIP/2.0 513 Message too big
85.111.0.205:5060 -> 85.111.0.205:5060
ACK
--Message too big and ACK repeated 5 times--
