[Serusers] Configuring SER to work as SIP proxy
by dzus＠mat.uni.torun.pl 24 Jul '07

24 Jul '07

All, I am trying to configure SER to work as SIP proxy (not registar and not redirect). I tried to modify simple ser.cfg which comes with SER by adding one line in route[0]: rewritehostport("192.168.1.2:5060"); This unfortunately doesn't work. The message to my SIP server 192.168.1.2 are indeed forwarded. But message comming back from 192.168.1.2 are looped by my SIP proxy (192.168.1.3) back to SIP server (192.168.1.2). Can someone help me? Or send a working cfg for SIP proxy, I cannot find any. This is my complete ser.cfg: # # $Id: ser.cfg,v 1.25.2.1 2005/02/18 14:30:44 andrei Exp $ # # simple quick-start config script # # ----------- global configuration parameters ------------------------ #debug=3 # debug level (cmd line: -dddddddddd) #fork=yes #log_stderror=no # (cmd line: -E) /* Uncomment these lines to enter debugging mode fork=no log_stderror=yes */ check_via=no # (cmd. line: -v) dns=no # (cmd. line: -r) rev_dns=no # (cmd. line: -R) port=5060 children=4 fifo="/tmp/ser_fifo" # ------------------ module loading ---------------------------------- # Uncomment this if you want to use SQL database #loadmodule "//lib/ser/modules/mysql.so" loadmodule "//lib/ser/modules/sl.so" loadmodule "//lib/ser/modules/tm.so" loadmodule "//lib/ser/modules/rr.so" loadmodule "//lib/ser/modules/maxfwd.so" loadmodule "//lib/ser/modules/usrloc.so" loadmodule "//lib/ser/modules/registrar.so" loadmodule "//lib/ser/modules/textops.so" # Uncomment this if you want digest authentication # mysql.so must be loaded ! #loadmodule "//lib/ser/modules/auth.so" #loadmodule "//lib/ser/modules/auth_db.so" # ----------------- setting module-specific parameters --------------- # -- usrloc params -- modparam("usrloc", "db_mode", 0) # Uncomment this if you want to use SQL database # for persistent storage and comment the previous line #modparam("usrloc", "db_mode", 2) # -- auth params -- # Uncomment if you are using auth module # #modparam("auth_db", "calculate_ha1", yes) # # If you set "calculate_ha1" parameter to yes (which true in this config), # uncomment also the following parameter) # #modparam("auth_db", "password_column", "password") # -- rr params -- # add value to ;lr param to make some broken UAs happy modparam("rr", "enable_full_lr", 1) # ------------------------- request routing logic ------------------- # main routing logic 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"); break; }; if (msg:len >= 2048 ) { sl_send_reply("513", "Message too big"); break; }; # we record-route all messages -- to make sure that # subsequent messages will go through our proxy; that's # particularly good if upstream and downstream entities # use different transport protocol if (!method=="REGISTER") record_route(); # subsequent messages withing a dialog should take the # path determined by record-routing if (loose_route()) { # mark routing logic in request append_hf("P-hint: rr-enforced\r\n"); route(1); break; }; if (!uri==myself) { # mark routing logic in request append_hf("P-hint: outbound\r\n"); route(1); break; }; # if the request is for other domain use UsrLoc # (in case, it does not work, use the following command # with proper names and addresses in it) if (uri==myself) { if (method=="REGISTER") { # Uncomment this if you want to use digest authentication # if (!www_authorize("iptel.org", "subscriber")) { # www_challenge("iptel.org", "0"); # break; # }; save("location"); break; }; lookup("aliases"); if (!uri==myself) { append_hf("P-hint: outbound alias\r\n"); route(1); break; }; # native SIP destinations are handled using our USRLOC DB if (!lookup("location")) { sl_send_reply("404", "Not Found"); break; }; }; append_hf("P-hint: usrloc applied\r\n"); route(1); } route[1] { # send it out now; use stateful forwarding as it works reliably # even for UDP2TCP # Dzus rewritehostport("192.168.1.2:5060"); if (!t_relay()) { sl_reply_error(); }; } ---------------------------------------------------------------- This message was sent using IMP, the Internet Messaging Program.

[OpenSER-Users] Error with authentication "ha1"
by Iñaki Baz Castillo 24 Jul '07

24 Jul '07

Hi, I've configured: modparam("auth_db", "calculate_ha1", 0) modparam("auth_db", "password_column", "ha1") # Default value modparam("auth_db", "password_column_2", "ha1b") # Default value Twinkle softphone uses digest with "username=user@domain" so OpenSer verifies the hash with the "ha1b" column and it works well, it's authenticated. But Linksys PAP2 uses digest with just "username=user" so OpenSer uses "ha1" column. I don't know why but it fails. Of course both can authenticate perfectly using modparam("auth_db", "calculate_ha1", 1) modparam("auth_db", "password_column", "password") Both users are generated with "openserctl add" command. Any idea why it fails with Linksys PAP2? I use OpenSer 1.2.1 of Debian testing. Thanks. -- Iñaki Baz Castillo ibc(a)in.ilimit.es

[OpenSER-Users] NEW FEATURE: new logging design
by Bogdan-Andrei Iancu 24 Jul '07

24 Jul '07

Hi, OpenSER trunk has a new logging design, covering new functionalities (for end-user), more simplicity (for developers), better log format, etc. End-user functionalities ========================= 1) configurable debug level at runtime - so far we had static debug level, but now, there is a MI function to change it at runtime. If you want to have or not a configurable debug level, there is a compile option named CHANGEABLE_DEBUG_LEVEL (see Makefile.defs). By default is on, but, if there are performance concerns, you can turn it off. The MI function is called "debug": # display the current debug level openserctl fifo debug # set a new debug level (L_ERR) openserctl fifo debug -1 The function changes the global debug level, so all processes and all code will be affected. 2) script function for changing the debug level - this functions allows you to change the debug level from script, only for a specific script block. Only the debug level of the current process will be changed. This is very helpful if you are tracing and debugging only a specific piece of code. The script function is: setdebug(4); # set debug level for debug setdebug(); # reset the debug level to the global one Ex: debug= -1 # err only ..... { ...... setdebug(4); uac_replace_from(....); setdebug(); ....... } The function change the debug level of the current process and changing the global debug level (MI function) does not affect it, so be careful and reset the pre process debug level when you are done. More simplicity ================= The logging function used in code was replaced with a new set of functions, more simple and flexible: LOG / DBG were replaced with: LM_ALERT( ...) LM_CRIT( ...) LM_ERR( ...) LM_WARN( ...) LM_NOTICE( ...) LM_INFO( ...) LM_DBG( ...) Prototype is LM_XXX( "FMT", .....); The functions will automatically add to the logged message the log level, the module name, function name, process pid and time stamp, so you do not have to care about it from the code. Better log format ================== Even if you use syslog or stderr logging, the log message will contain information about log level, the module name, function name, process pid and time stamp. For syslog, the log level is mapped over the syslog levels, so no text will be used - you can configure syslog to use different files for each log level. Also time and pid are not pushed from openser as this info is automatically logged by syslog. For stderr logging, openser take care and appends the log level as text, time and pid (as text). Ex: Jul 23 19:52:19 [0] INFO:sl:mod_init: Initializing StateLess engine So, either you are using syslog, either stderr, you will still get the same information logged. We still need to migrate all the log messages from script from the old to the new set of functions, so, for the moment, not all logs will be "nice" formatted. Regards, Bogdan

[OpenSER-Users] OpenSER + FreeRadius + CDRTool
by Marc LEURENT 24 Jul '07

24 Jul '07

Good Morning everybody, I hope you had a pleasant week-end! I'm trying to set up an infrastructure for prepaid calls for my school working with OpenSER + Freeradius + CDRTool OpenSER is working well with FreeRadius, but I have followed the CDRTool installation tutorial and now Freeradius doesn't work anymore... Both OpenSER and freeradius data is stored in an mysql database, but when I was installing CDRTool, I had to modify their database following http://cdrtool.ag-projects.com/doc/INSTALL.txt Is there someone who succeed in setting up this installation... Any Help or just any hope to succeed? PS: I'm using OpenSER 1.2.1-1 compiled by hand, Freeradius 1.1.3-3 and cdrtool_5.2.1_all.deb Marc

[OpenSER-Users] SipSpy release (How to see sip messages in openser, or whatever SIP software you use)
by Elias Baixas 24 Jul '07

24 Jul '07

Hi all, just wanted to let you know that we have released our visual SIP monitoring tool as OSS (GPL'd). You can take a look on what it does (and how) on http://www.wesip.com/mediawiki/index.php/SipSpy basically, SipSpy is composed of 2 softwares: an agent and a manager. You run the agent in all the nodes where you want to monitor SIP traffic, and the manager (User Interface) in your computer. THen the manager (SipSpy) connects to each of the agents through TCP, and they report any SIP packet that matches a given regexp to the manager. MOre or less its like having a couple of ngreps running on different hosts, but reporting the seen SIP packets to a nice graphical User Interface, so that you can see what's happening in all the nodes in real time from your desktop. ngrep is tough for starters !

[Serusers] Transfering incoming call on SER to Asterisk
by inge 24 Jul '07

24 Jul '07

Hi all, Anyone know how can I transfer an incoming call from SER to an Asterisk ? The sip uri wich comes from SER is like : sip:enum@domain.tld But on Asterisk enum will not be necessary the extension. IT seems that with a single rewritehostport to Asterisk, it doesn't run. Thanks for your support Adrien

[OpenSER-Users] bug ? remote mysql server in openser-devel
by Julien REVERET 23 Jul '07

23 Jul '07

Hi, I'm currently using openser-devel release 2497 and I'm facing what I think is a bug. I'm using a remote mysql server. My openser.cfg file contains the following lines : loadmodule "/usr/local/lib/openser/modules/mysql.so" loadmodule "/usr/local/lib/openser/modules/usrloc.so" loadmodule "/usr/local/lib/openser/modules/auth.so" loadmodule "/usr/local/lib/openser/modules/auth_db.so" loadmodule "/usr/local/lib/openser/modules/uri_db.so" modparam("usrloc", "db_mode", 2) modparam("auth_db", "calculate_ha1", 1) modparam("auth_db", "password_column", "password") modparam("auth_db", "user_column", "username") modparam("auth_db", "domain_column", "domain") modparam("usrloc|auth_db","db_url","mysql://foo:bar@192.168.1.62:3306/openser") When starting openser, I get these lines in the logs : openser[30331]: INFO: statistics manager successfully initialized openser[30331]: StateLess module - initializing openser[30331]: TM - initializing... openser[30331]: maxfwd:initializing openser[30331]: INFO:ul_init_locks: locks array size 512 openser[30331]: TextOPS - initializing openser[30331]: new_connection: Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2) openser[30331]: ERROR: uridb_db_ver: unable to open database connection openser[30331]: ERROR: uri_db:mod_init(): Error while querying table version openser[30331]: init_mod(): Error while initializing module uri_db openser[30331]: INFO:mi_fifo:mi_destroy: process hasn't been created -> nothing to kill I tried to launch a local mysql and as far as I can see, openser only connects to the local server, it doesn't do any requests. So is there a bug or am I missing something ? -- Julien REVERET OSIATIS - LIFO https://www.lifo-osiatis.com

[Users] 473 Filtered destination?
by Tobias Lindgren 23 Jul '07

23 Jul '07

Hi, recently moved from SER > OpenSER 1.2.0, but after some time when the server is running OpenSER starts to respond with: "SIP/2.0 473 Filtered destination (473/TM)." to my INVITEs. I don't have any blacklists/accesslist configured (the config is from SER which doesn't support that), why am I seeing this problem? Br, /Tobias
