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 foundMar 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

Hello,

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

kamcmd core.sockets_list

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

Hello,

oh, forgot to follow up, as I read your response at some point.

Are you doing force_send_socket() or $fs = ...? If yes, what is the socket value you are forcing?

The log message said:

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)

The socket listen in the rpc command output is udp:10.70.0.75:5060.

However this is only when the listening socket is the VIP, if I define the true private local address to listen on, dispatcher works nicely.

Can you set force socket for dispatcher module when using probing?

Hello,

oh, forgot to follow up, as I read your response at some point.

Are you doing force_send_socket() or $fs = ...? If yes, what is the socket value you are forcing?

The log message said:

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)

The socket listen in the rpc command output is udp:10.70.0.75:5060.

Cheers, Daniel

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

Hello,

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

kamcmd core.sockets_list

    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:

    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

Hi Daniel,

Thanks for the reply, sorry I keep missing you ! :)

I have added force_send_socket in the correct places now , and I can now make inbound/outbound calls are required.

However with dispatcher, when Im trying to send SIP options pings to gateways defined, I see these errors;

However this is only when the listening socket is the VIP, if I define the true private local address to listen on, dispatcher works nicely.

Can you set force socket for dispatcher module when using probing?

Thanks

Jon
