[OpenSER-Users] About t_replicate
by Ali Jawad 09 Jun '08

09 Jun '08

Hi All As per previous Q "mentioned below" I did try using t_replicate however once the client A logons on to server A it just keeps sending subscribe requests to server B Hi All I have the following scenario Openser Server A --> Uses Localhost MySQL Server Openser Server B --> Uses ServerA MySQL server Each server is in a different location. Both servers share the same database. I.e. in other words a user can successfully logon to either server. Both servers have a similar configuration file. My problem at hand is the following User A and User C logon to Server A User B logs on to Server B User A and User C can call each other. How can User A and C communicate with user B ? Can anyone provide me with a working example. My Config ####### Modules Section ######## #set module path mpath="/usr/local/lib/openser/modules/" /* uncomment next line for MySQL DB support */ loadmodule "mysql.so" loadmodule "sl.so" loadmodule "tm.so" loadmodule "rr.so" loadmodule "maxfwd.so" loadmodule "usrloc.so" loadmodule "registrar.so" loadmodule "textops.so" loadmodule "mi_fifo.so" loadmodule "uri_db.so" loadmodule "uri.so" loadmodule "xlog.so" loadmodule "auth.so" loadmodule "auth_db.so" # ----- rr params ----- # add value to ;lr param to cope with most of the UAs modparam("rr", "enable_full_lr", 1) # do not append from tag to the RR (no need for this script) modparam("rr", "append_fromtag", 0) # ----- rr params ----- modparam("registrar", "method_filtering", 1) /* uncomment the next line to disable parallel forking via location */ # modparam("registrar", "append_branches", 0) /* uncomment the next line not to allow more than 10 contacts per AOR */ #modparam("registrar", "max_contacts", 10) # ----- uri_db params ----- modparam("uri_db", "use_uri_table", 0) modparam("uri_db", "db_url", "mysql://db_string") # ----- usrloc params ----- modparam("usrloc", "db_mode", 3) modparam("usrloc", "db_url","mysql://db_string") # ----- auth_db params ----- modparam("auth_db", "calculate_ha1", yes) modparam("auth_db", "password_column", "password") modparam("auth_db", "use_domain", 0) modparam("auth_db", "db_url","mysql://db_string") modparam("usrloc", "db_url","mysql://db_string") # ----------------- setting module-specific parameters --------------- # -- mi_fifo params -- modparam("mi_fifo", "fifo_name", "/tmp/openser_fifo_xmpp") # -- usrloc params -- # -- rr params -- # add value to ;lr param to make some broken UAs happy modparam("rr", "enable_full_lr", 1) ###### Routing Logic ######## route { if(!mf_process_maxfwd_header("10")){ sl_send_reply("486", "To Many Hops"); return; } if(msg:len >= max_len){ sl_send_reply("513", "Message To Big"); return; } #########End of XMPP Section ################### if(!is_method("REGISTER")){ record_route(); } if(loose_route()){ route(1); return; } if(uri == myself){ if(is_method("REGISTER")){ if(!www_authorize("mydomain.net", "subscriber")){ www_challenge("mydomain.net", "1"); return; } save("location"); if(!src_ip==xx.yy.zz.12) { t_replicate("xx.yy.zz.12", "5060"); }; return; } if(does_uri_exist()){ # local uri does exist, is probably a user. # lookup location if(lookup("location")){ route(1); return; } } else { # probably a call to pstn.... route(2); return; } } } route[1] { # for INVITEs enable some additional helper routes if (is_method("INVITE")) { t_on_branch("2"); t_on_reply("2"); t_on_failure("1"); } if (!t_relay()) { sl_reply_error(); }; exit; } route[2] { # pstn handling, simply route out to pstn. xlog("L_INFO","rewritehostport to Splendor_VOIP_GW:5065"); sl_send_reply("100","Call Going To PSTN"); sethostport("xx.yy.zz.39"); route(1); } /* route[2] { # for INVITEs enable some additional helper routes rewritehostport ("xx.yy.zz.39:5060"); xlog("L_INFO","rewritehostport to Splendor_VOIP_GW:5065"); route(1); } */ # Presence route /* uncomment the whole following route for enabling presence NOTE: do not forget to enable the call of this route from the main route */ branch_route[2] { xlog("new branch at $ru\n"); } onreply_route[2] { xlog("incoming reply\n"); }

[OpenSER-Users] Dialog module
by David Villasmil 09 Jun '08

Hello List, I have a simple load balancer with dispatcher. I'm using the DIALOG module, it is supposed to store in db all info about ongoing dialogs. But my setup must be wrong, because a lot of dialogs are not removed when the call is hung up. Here's my cfg: # # $Id: openser.cfg 1827 2007-03-12 15:22:53Z bogdan_iancu $ # # simple quick-start config script # Please refer to the Core CookBook at http://www.openser.org/dokuwiki/doku.php # for a explanation of possible statements, functions and parameters. # # ----------- global configuration parameters ------------------------ debug=3 # debug level (cmd line: -dddddddddd) fork=yes log_stderror=no # (cmd line: -E) children=4 check_via=no dns=no rev_dns=no listen=a.b.c.d disable_dns_blacklist=true port=5060 #set module path mpath="/lib/openser/modules/" # ------------------ module loading ---------------------------------- loadmodule "mysql.so" loadmodule "maxfwd.so" loadmodule "sl.so" loadmodule "dispatcher.so" loadmodule "tm.so" loadmodule "mi_fifo.so" loadmodule "textops.so" loadmodule "xlog.so" loadmodule "rr.so" loadmodule "dialog.so" loadmodule "avpops.so" modparam("mi_fifo","fifo_name", "/tmp/openser_fifo") modparam("tm", "fr_timer", 5) modparam("dispatcher", "list_file", "/etc/openser/dispatcher.list") modparam("dispatcher", "flags", 2) modparam("dispatcher", "force_dst", 1) modparam("dispatcher", "dst_avp", "$avp(i:271)") modparam("dispatcher", "grp_avp", "$avp(i:272)") modparam("dispatcher", "cnt_avp", "$avp(i:273)") modparam("dialog", "dlg_flag", 4) modparam("dialog", "db_mode", 1) modparam("dialog", "table_name", "dialog") modparam("dialog", "db_url", "mysql://user:pass@localhost/openser") modparam("avpops","avp_url","mysql://user:pass@localhost/openser") modparam("avpops", "avp_table", "dialog") route{ # initial sanity checks -- messages with # max_forwards==0, or excessively long requests if (!mf_process_maxfwd_header("10")) { sl_send_reply("483","Too Many Hops"); exit; }; if (msg:len >= 2048 ) { sl_send_reply("513", "Message too big"); exit; }; if (!method=="REGISTER") record_route(); if (method=="INVITE") { setflag(4); } if ( method=="INVITE" || method=="ACK" || method=="BYE" || method=="OPTIONS" || method=="CANCEL" ) { ds_select_dst("1","2"); t_on_failure("1"); t_relay(); exit; }; } failure_route[1] { if (t_check_status("408")) { xlog("L_INFO","Marking GW as failed...\n"); ds_mark_dst("p"); ds_next_dst(); t_on_failure("1"); t_relay(); } else{ t_reply("501","Not Implemented"); } } As far as I know, using the record_route assures that all messages are passed through the proxy so that dialogs must be removed... but they'r not Any ideas? Thanks a lot. David Villasmil

[OpenSER-Users] AVPOPS Issue
by Ali Jawad 09 Jun '08

09 Jun '08

Hi All I have added a column called status to the subscriber table. I want to check that column in the route() function and act according to it's value. In the global settings I put # ----- AVP params -------- modparam("avpops", "avp_url", "mysql://openser:ccccc@cccccc/openser") modparam("avpops","avp_table","subscriber") modparam("avpops","db_scheme", "scheme1:username_col=username;value_col=status;value_type=string;table= subscriber") And In the route statement I put if (avp_db_load("$ru","$avp(s:disabled)/$scheme1")) { xlog("L_INFO", "This did match"); } I am getting this error in the log file Jun 9 09:12:51 [15789] ERROR:avpops:ops_dbload_avps: incomplet uri <sip:xx.xx.xx.xx> "Where xx.xx.xx.xx is my correct IP" And the IF statement is matching everytime. Thanks for any suggestions.

Depending if you want to run with one or two database servers, where you can have also replication options. It is also a possibility to use t_replicate to replicate registrations, but it getx more complex with NAT environments.

[OpenSER-Users] OpenSER and MySQL cpu utilization question
by John Barry 09 Jun '08

09 Jun '08

Hello, I am using OpenSER 1.3.0 with digest authentication (MySQL database) in a multiprocessor machine (4 CPU). When using OpenSER configured with one child. I have noticed that OpenSER process can reach a maximum CPU utilization of 70% while the MySQL DB reaches around 30% CPU utilization (100% in total). Tipically the OpenSER process and the MySQL process will be using the same processor. However, this behavior happens also if I forced each processor to use different processors (using processor affinity). My question is why the OpenSER and the DB processes can't use more CPU time if they are running in independent processors (they behave as if they were running in a single processor). What is the dependency/relationship between the OpenSER and MySQL processes?

[OpenSER-Users] serMyAdmin on www.sermyadmin.org
by Zen Kato 09 Jun '08

09 Jun '08

I upgraded from tomcat5.5.15 to tomcat6.0.16 on fc5. After I entered username: admin(a)192.168.0.3 Password:xxxx on the screen of http://192.168.0.3:8080/serMyAdmin/auth/login, [Login] click doesn't work. Only [Register] click goes to http://192.168.0.3:8080/serMyAdmin/newUser/create Is this a correct behavior of serMyAdmin? I followed up inside of openser.sql of Step 17: Create the administrator user in the database. on Last Updated ( Friday, 02 May 2008 16:55 ) web infomation, but I don't know the reason of the following procedure(1),(2). (1) ALTER TABLE `domain` ALTER `last_modified` SET DEFAULT '2008-01-01 00:00:00'; UPDATE domain set `last_modified`='2008-01-01 00:00:00'; INSERT INTO `domain` (`id`, `domain`, `last_modified`, `version`) VALUES (2, 'setup', '2008-04-09 16:13:12', 0); (2) INSERT INTO `jsec_user_role_rel` (`id`, `version`, `role_id`, `user_id`) VALUES (1, 0, 1, 4), (3, 0, 1, 7), (4, 0, 1, 3), (5, 0, 3, 11); Do I miss somthing to run serMyAdmin? -- Zen

[OpenSER-Users] mirror proxy/upstream Registrar
by sylver_b 09 Jun '08

09 Jun '08

Hi Thanks for your reply. Yes in fact, the registrar is some sort of a billing application that enforce AAA. The only problem is , it does not handle NAT traversal. That's why we need OpenSer to act as an SBC.

Do you mean that an INVITE should be forwarded to a registrar server? maybe the registrar is also a proxy/PBX? Please, explain a little more your escenario.

[OpenSER-Users] mirror proxy/upstream Registrar
by sylver_b 08 Jun '08

08 Jun '08

Hello, We would like to evaluate OpenSER to test interoperability with our sip registrar platform - as our registrar does not handle NAT Traversal we would like to use OpenSER as a mirror proxy . Basically we would like OpenSER to act as an Upper Registrar proxy where all the sip messages would be forwarded to our registrar, based on the domain name used in the Register. ie: REGISTER 111(a)domain1.com -> forward to -> registrar_ip1 REGISTER 222(a)domain2.com -> forward to -> registrar_ip2 and so on... If a call is initiated, OpenSER should transparently handle NAT traversal functionalities while forwarding the INVITE request to the proper registrar server. Below some detailed requirements: Upper Registration is the capability of a SBC to proxy Registrations towards an upstream Registrar. While it is necessary that all SIP requests traverse the SBC for NAT continuity, Registrations should be allowed to be relayed towards the upstream Registrar while the SBC retains a copy of the AOR and masquerade on behalf of the UA that send the registration request. Please let us know the best way to configure OpenSER to achieve this type of configuration. Thanks SB _____________________________________________________________________________ Envoyez avec Yahoo!
