Re: [sr-dev] [SR-Users] Force socket on reply

Hello,

can you send the patch with 'git diff' or 'diff -u' -- it will be easier to apply and analyze it. Once I get it, I will look over the case you reported in more details.

Thanks, Daniel

Hi Daniel..

I'm using version 3.1.0. I looked at the change but its done only for forward_reply.. How about relay_reply()?

Thanks Jijo

Hello,

I haven't understood exactly what you tried? Was it use of
force_send_socket(...) in onreply_route and didn't work? If yes,
what version are you runing, there was a fix for such case some
time ago:

Cheers,

Hi All,

Our system has two IP address, one is used for kamailio and 2nd
one is used for data.
The problem is suppose a request came in to kamailio on a TCP
connection with first IP address and connection is torned down
before sending the response. Later when the response is send out 
kamialio is using the 2nd IP to create the connection. The reason
is kamailio doesn't have force socket in in reply, so it uses
INADDR_ANY for soruce addres .so kernel uses source address based
on the detaintion IP.
I tired to force the socket using pseudo variable $fs or
force_send_socket(), but neither of them worked from reply_route.
So i modfied the code relay_replay to set the SND_F_FORCE_SOCKET
which will use the address where request is recieved  as source
address to make the TCP connection  The code change is shown below.
Please let me know is there anyother way we could acheive it?
   }else{
    buf = build_res_buf_from_sip_res( relayed_msg, &res_len );
    /* if we build a message from shmem, we need to remove
       via delete lumps which are now stirred in the shmem-ed
       structure
    */
    if (branch!=relay) {
     free_via_clen_lump(&relayed_msg->add_rm);
    }
    /* update send_flags with possible additions from the
       reply route */
    SND_FLAGS_OR(&uas_rb->dst.send_flags, &uas_rb->dst.send_flags,
&relayed_msg->rpl_send_flags);
                /* Make theresponse to use the same IP where it
receives the message */
**
*uas_rb->dst.send_flags.f |= SND_F_FORCE_SOCKET; *
  }
Thanks
JIjo
