Planning for new functionality for kamailio
by Vadim Lebedev 01 Jun '09

01 Jun '09

Hello, I'd like to discuss some new functionaity for Kamailio i intend to develop for a client. My client need to integrate very specific transport security layer... The layer will function over tcp and udp and will be intgreated into the SSL framework The client will provide a function returning SSL_METHOD * descritptor So what i need to do is 1) Add possibility to use SSL over udp socket 2) To use a new SSL method So my first question is: Is there any chance that such functionality … [View More]

[RtpProxy] debian init patch to be LSB compliant
by Iñaki Baz Castillo 31 May '09

31 May '09

Hi, I attach a ptch for rtpproxy Debian init script which allows it being LSB compliant. Basically I add "--oknodo" option to all calls to "start-stop-daemon" which, by default, is not LSB compliant. Being LSB compliant is really useful when we want to manage a service (like RtpProxy) using some failover system as HeartBeat, which relies on *exact* reply code of the init scripts. About LSB specification [1] for init scripts which I refer to: --------------------- "For all other init-… [View More]

[rtpproxy module] set_rtp_proxy_set() to allow pv as parameter
by Iñaki Baz Castillo 31 May '09

31 May '09

Hi, using multiple RtpProxy instancies would be more flexible if set_rtp_proxy_set() allows a pseudo-variable instead of just a fixed integer. Without this feature, it's impossible to implement real RtpProxy loadbalancing since: how to use the same RtpProxy for an in-dialog request? Let me show an example: - Let's suppose we have these rtpproxies: modparam("nathelper", "rtpproxy_sock", "1 == udp:1.1.1.1:12221") modparam("nathelper", "rtpproxy_sock", "2 == udp:2.2.2.… [View More]2:12221") (note that I don't use various rtpproxies in the same set since with the, real loadbalancing it's not possible). - An INVITE arrives and we want to use a ramdom rtpproxy (set 1 or 2). Since set_rtp_proxy_set() doesn't allow pv, the only way is something as computing the from_tag or call-id and get values 0 or 1 (or 1 or 2). In the first case we invoke set_rtp_proxy_set("1") and in the second set_rtp_proxy_set("2"). - When processing the 183/200 response we should do the same (get 1 or 2 from the from_tag or call-id), or perhaps add a parameter in RR (rtpproxy_set=1) and invoke the corresponding set_rtp_proxy_set() function. - The same for every in-dialog request (re-INVITE, BYE...). I understand that this mechanims is not really scalable since adding a new rtpproxy requires modifications in the kamailio script (the ramdom function which now should return 1, 2 or 3 depending on the call-id/from_tag hash or something similar) and also adding a new "else if (XXXXX) { set_rtp_proxy_set("3") ... }" So, extending set_rtp_proxy_set() to allow pv would mitigate this issue: - When the INVITE arrives a ramdom function returns 1,2,3..., we store that value in a pv and use it into set_rtp_proxy_set(). - We also store that value in a RR param to retrieve it in replies and in- dialog requests in order to invoke the samertpproxy set. About various rtpproxy instances per set: I consider there is no solution for it. If we have: # multiple rtproxies for LB modparam("nathelper", "rtpproxy_sock", "udp:localhost:12221 udp:localhost:12222") We invoke "rtpproxy_offer" and some rtpproxy has been transparently selected, but we CANNOT know which one, so, how to reuse it in the reply and in-dialog requests?? I remember a thread about it in which the code was inspected and some "hash algorithm" resulted to take place to select the rtpproxy instance. However I remember that this algorithm is not so robust as required for a real loadbalancing system. So, in conclusion, is there any aim in improving RtpProxy module to allow real and robust load-balancing? What about multiple rtpproxy instances in the same set? is it really usable? Thanks a lot for any comment on it. -- Iñaki Baz Castillo <ibc(a)aliax.net> [View Less]

[rtpproxy] ERR:create_twinlistener: unable to set TOS to 184: Operation not permitted
by Iñaki Baz Castillo 31 May '09

31 May '09

Hi, when rtpproxy is running as non root user, it gives this error for each request (anyway it doesn't fail): ERR:create_twinlistener: unable to set TOS to 184: Operation not permitted I've not checked it running as root however. How could I avoid this error? I don't see options in rtpproxy to dissable the TOS modification. -- Iñaki Baz Castillo <ibc(a)aliax.net>
