Hi all, Here is my confusion about SER supporting NAT transversal. 1. With only RTPProxy, what kinds of types of NAT can SER with nathelper transverse? 2. What's the difference between MediaProxy and RTPProxy? 3. If UA supports STUN, do SER need to configure nathelper to support NAT transversal? Just because I knew STUN protocol only process a few kinds of types of NAT, I want to know what advantage it will add if I configure SER with nathelper. Thanks a lot! 　　　　　　　　ljzhang 　　　　　　　　xueyou38(a)163.com 　　　　　　　　　　2005-04-12

[Serusers] Load Balancing via UltraMonkey/ldirectord
by Matt Schulte 13 Apr '05

13 Apr '05

Has anyone attempted to load balance SER using Ultramonkey/ldirectord? I've noticed all it does is pretty much NAT and send requests accordingly, the trick I guess would be the NAT part. If the SIP headers = myself, would there really be any issues? One problem I can foresee is the possibility that loose routing would hit the wrong server. Just wanted to ask around before I wasted time trying it out for myself :-) Thanks Matt

RE: [Serusers] LCR failure syntax
by Matt Schulte 13 Apr '05

13 Apr '05

Ok, I've checked over my config and am going bananas. I cannot get a "failover" scenario working. The first LCR load_gw is fine however whenever a call fails (in this instance I am generating a 404) it never sees the second priority. Thoughts? I Dial 636561XXXX I checked my logs, everything goes through just fine, get the 404 (per failover test), it gets caught by the failure if statement and spits out no more gateways.. lcr table (accounting for e164 and non) +------------+----------+--------+----------+ | prefix | from_uri | grp_id | priority | +------------+----------+--------+----------+ | +1636 | % | 2 | 1 | | +1636 | % | 1 | 2 | | 636 | % | 2 | 1 | | 636 | % | 1 | 2 | +------------+----------+--------+----------+ route[99] { t_on_failure("2"); if(!load_gws()) { sl_send_reply("500", "Internal server error, unable to load gateways"); break; } log (1, "Running next_gw\n"); if(!next_gw()) { sl_send_reply("503", "Service not available, no gateways found"); xlog("L_INFO", "<%ru> <%br>\n"); break; } xlog("L_INFO", "Time %Tf RURI <%ru> \n"); t_relay(); break; } failure_route[2] { log(1, "Hit failure route 2\n"); if(method == "INVITE" && t_check_status("408|500|503|480|400|404")) { xlog("L_INFO", "NOTICE: Hit failure 2 and error status code\n"); if (!next_gw()) { xlog("L_INFO", "ERROR: No more gateways for LCR failover dropping call\n"); t_reply("503", "Service not available, no more gateways"); break; } t_on_failure("2"); # ... t_relay(); } } -----Original Message----- From: Andres [mailto:andres@telesip.net] Sent: Thursday, April 07, 2005 5:11 PM To: Matt Schulte Cc: serusers(a)lists.iptel.org Subject: Re: [Serusers] LCR failure syntax Matt Schulte wrote: >Could anyone post a working example of the lcr next_gw syntax for >failure routes?

RE: [Serusers] Load Balancing via UltraMonkey/ldirectord
by Matt Schulte 13 Apr '05

Heheh, we may actually test one of those F5network switches...i f we don't come up with a fairly painless, bugfree, and most importantly supportable solution. :-) I cannot code therefore I would be useless, but I can safely say learning C is on my to-do list. We may however be willing to contribute to a bounty, at the very least I'd be more than happy to test :D Matt -----Original Message----- From: Greger V. Teigre [mailto:greger@teigre.com] Sent: Tuesday, April 12, 2005 5:29 AM To: Matt Schulte; serusers(a)lists.iptel.org Subject: Re: [Serusers] Load Balancing via UltraMonkey/ldirectord :-) Yes, layer 7 switch is of course nice. But then again, you need to make sure that you can price your services where people will buy them... I wonder whether it is possible to gather some people interested in this and get something started on the development side. AFAIK, LVS struggles with other UDP services too, so a ipvs UDP content analyzer would probably be of interest. I looked at the source code and I think the most difficult thing would be to extend the ipvs framework to allow a module to peak into the packet (and not only the header). I don't know what kind of performance penalties you get either. I have seen several people being willing to sponsor development.

Hello , I have installed the SER-0.9.0 +nathelper+rtpproxy,it can let the the SER through the nat by the rtpproxy. But there are a problem . The endpoint would sent Bye message to SER when it connect the SER about 32 sec. I have tested some endpoints but it is the same (only can maintain 32 sec connecting). Why? I don't know how to solve the problem. My config file following: dns=no rev_dns=no fifo="/tmp/ser_fifo" fifo_db_url="mysql://ser:heslo@localhost/ser" loadmodule "/usr/local/lib/ser/modules/mysql.so" loadmodule "/usr/local/lib/ser/modules/sl.so" loadmodule "/usr/local/lib/ser/modules/tm.so" loadmodule "/usr/local/lib/ser/modules/rr.so" loadmodule "/usr/local/lib/ser/modules/maxfwd.so" loadmodule "/usr/local/lib/ser/modules/usrloc.so" loadmodule "/usr/local/lib/ser/modules/registrar.so" loadmodule "/usr/local/lib/ser/modules/auth.so" loadmodule "/usr/local/lib/ser/modules/auth_db.so" loadmodule "/usr/local/lib/ser/modules/nathelper.so" loadmodule "/usr/local/lib/ser/modules/textops.so" loadmodule "/usr/local/lib/ser/modules/uri_db.so" loadmodule "/usr/local/lib/ser/modules/uri.so" loadmodule "/usr/local/lib/ser/modules/domain.so" modparam("auth_db|usrloc|uri_db", "db_url", "mysql://ser:heslo@localhost/ser") modparam("auth_db", "calculate_ha1", 1) modparam("auth_db", "password_column", "password") modparam("nathelper", "natping_interval", 30) modparam("nathelper", "ping_nated_only", 1) modparam("nathelper", "rtpproxy_sock", "unix:/var/run/rtpproxy.sock") modparam("usrloc", "db_mode", 2) modparam("registrar", "nat_flag", 6) modparam("rr", "enable_full_lr", 1) route { # ----------------------------------------------------------------- # Sanity Check Section # ----------------------------------------------------------------- if (!mf_process_maxfwd_header("10")) { sl_send_reply("483", "Too Many Hops"); break; }; if (msg:len > max_len) { sl_send_reply("513", "Message Overflow"); break; }; # ----------------------------------------------------------------- # Record Route Section # ----------------------------------------------------------------- if (method!="REGISTER") { record_route(); }; if (method=="BYE" || method=="CANCEL") { unforce_rtp_proxy(); } # ----------------------------------------------------------------- # Loose Route Section # ----------------------------------------------------------------- if (loose_route()) { if (has_totag() && method=="INVITE") { if (nat_uac_test("19")) { setflag(6); force_rport(); fix_nated_contact(); }; force_rtp_proxy("l"); }; route(1); break; }; # ----------------------------------------------------------------- # Call Type Processing Section # ----------------------------------------------------------------- if (uri==myself) { if (method=="INVITE") { route(3); break; } else if (method=="REGISTER") { route(2); break; }; if (!lookup("location")) { sl_send_reply("404", "User Not Found"); break; }; route(1); }; } route[1] { # ----------------------------------------------------------------- # Default Message Handler # ----------------------------------------------------------------- t_on_reply("1"); if (!t_relay()) { if (method=="INVITE" && isflagset(6)) { unforce_rtp_proxy(); }; sl_reply_error(); }; } route[2] { # ----------------------------------------------------------------- # REGISTER Message Handler # ---------------------------------------------------------------- if (!search("^Contact: \*") && nat_uac_test("19")) { setflag(6); fix_nated_register(); force_rport(); }; sl_send_reply("100", "Trying"); if (!www_authorize("","subscriber")) { www_challenge("","0"); break; }; if (!check_to()) { sl_send_reply("401", "Unauthorized"); break; }; consume_credentials(); if (!save("location")) { sl_reply_error(); }; } route[3] { # ----------------------------------------------------------------- # INVITE Message Handler # ----------------------------------------------------------------- if (nat_uac_test("19")) { setflag(6); } if (!lookup("location")) { sl_send_reply("404", "User Not Found"); break; }; if (!proxy_authorize("","subscriber")) { proxy_challenge("","0"); break; } else if (!check_from()) { sl_send_reply("403", "Use From=ID"); break; }; consume_credentials(); if (isflagset(6)) { force_rport(); fix_nated_contact(); force_rtp_proxy(); }; t_on_reply("1"); if (!t_relay()) { if(isflagset(6)) { unforce_rtp_proxy(); } sl_reply_error(); }; } onreply_route[1] { if (isflagset(6) && status=~"(180)|(183)|2[0-9][0-9]") { if (!search("^Content-Length:\ 0")) { force_rtp_proxy(); }; } else if (nat_uac_test("1")) { fix_nated_contact(); }; } _________________________________________________________________ Express yourself instantly with MSN Messenger!
