Hi Daniel,

Did you have any thoughts on this or is it more ip routing related or ucarp configuration on the server itself?

Looks like kamailio has it as a listening socket.

Thanks

Jon

Hi Daniel,

Thanks for the reply.  Yes its listed, however I see mhomed set to no? however I have defined as on.

socket: {

                proto: udp

                address: 10.70.0.75

                ipaddress: 10.70.0.75

                proto: 5060

                mcast: no

                mhomed: no

        }

ERROR: tm [ut.h:345]: uri2dst2(): no corresponding socket found for "10.70.0.73" af 2 (udp:10.70.0.73:5080)

Am I missing something?

Thanks

Hello,

can you see if the socket lists includes the IP address giving problems? Use the command:

kamcmd core.sockets_list

Cheers,
Daniel

Hi Guys,

Using Centos 6.7, kamailio 4.2 and Ucarp I am testing multiple VIPs on the same server and having some issues.

I have ucarp running, with  1 Public and 1 Private VIP defined, and both are pingable and failover in a cluster.

The Public is for Subscribers to Register with, and the Private for Communication to the Asterisk media servers behind it.

My problem is kamailio when started states its listening on both the VIPS, however when I try and force_socket over the  Private IP address, it states 

 ERROR: <core> [forward.c:218]: get_out_socket(): no socket found

Mar  1 20:04:35 bt1proxy1 /usr/sbin/kamailio[20372]: ERROR: <core> [forward.c:220]: get_out_socket(): no corresponding socket found for(udp:10.70.0.72:5080)

Mar  1 20:04:35 bt1proxy1 /usr/sbin/kamailio[20372]: ERROR: tm [t_fwd.c:520]: prepare_new_uac(): ERROR: can't fwd to af 2, proto 1  (no corresponding listening socket)

This is when listening on the VIP which is 10.70.0.75 and I also look to force_socket out of this IP.  It just doesnt work, however  if I use the physical interface on the server, that being 10.70.0.70, it works fine and forwards requests on the Private LAN.

I have added net.ipv4.ip_nonlocal_bind = 1 to sysctl.conf as well but no joy.

If 1 VIP is defined I have no issue, its just with 2, has anyone had this issue before ?

Any help would be great.

Many thanks

Jon
