[Kamailio-Users] strange fr_inv_timer behaviour

[Serusers] rtpproxy: How to force it to send packets out a specific interface?
by Frank Durda IV 06 Jul '09

06 Jul '09

I am running SER/rtpproxy on some systems with multiple cores and multiple ethernet interfaces. I am running multiple copies of rtpproxy, each with an IP address associated with a particular interface, as in one rtpproxy is using em1 which is 208.33.44.3 and em2 is 208.33.44.4 which another rtpproxy listens at, while ser listens in em0 at 208.33.44.2. These three (actually ten) interfaces pass through ethernet switches and then on to a router with a default gateway of 208.33.44.1 and then off to the Internet or wherever. (In my setup, each rtpproxy has a second interface pointing into a private network, so only one side of a call appears on any given interface and five face toward the Internet.) SER+rtpproxy correctly divides RTP traffic for calls to 208.33.44.3 and 208.33.44.4 in the SDP payloads, and callers send their RTP packets to the two rtproxies IP addresses without problems. That part works just fine. The problem is that rtpproxy is using the default route for transmission, so everything that goes towards the Internet goes out via em0, so em1 and em2 don't transmit anything. This means that this one link is overwhelmed by the traffic that should have been divided across multiple links. Rtpproxy is allowing the local route table and the default route to handle the outgoing packets and so the packets are all going out the same interface. In my case, em0 was 100Mbit/sec (completely sufficient for SIP messages, while em1 and em2 were gigabit links to handle RTP, but they are getting used only in one direction. Even if em0 was upgraded to Gbit, it would still not be able to handle the potential for 2+ Gbit of data from the rtproxies. So, is there any way to force rtproxy to perform what I believe they used to call "reflector mode", where the answers go out the same interface they come in on? (This used to be common on UDP-based NFS file servers.) A number of communication programs also allow this behavior as an option, but rtpproxy doesn't appear to do it or it isn't turned on by default. Because the destinations for the RTP are out on the Internet somewhere, I don't believe I can solve this via "route" or "ifconfig" settings, but would be delighted if someone knows different or knows of a setting change in rtpproxy that will do this so that load balancing will work. The OS in question is FreeBSD 7.2, but I have the same issue on 6.2 and 6.3. Thanks in advance!

[Kamailio-Users] kamailio with sqlops fails to start if DB is down
by logivoip＠gmail.com 01 Jul '09

01 Jul '09

Hi All, First off - thank you for this module. I have configured two redundant DB sources in my kamailio confiuration. The DB's are accessed from Kamailio for redundancy pruposes. Kamailio and the primary DB are on the same hardware node. The secondary DB is on a remote host. If Kamailio is up and both MySQL DB's are up, the config works like a charm. If the primary or the secondary DB becomes unreachable while Kamailio is up, the config handles the exception and all works well. However, if any of the DB servers becomes unreachable and Kamailio is restarted, Kamailio can no longer start. Below is an excerpt from my config file: # -- sqlops params modparam("sqlops","sqlcon","pridb=>mysql://root:@localhost/db_table") modparam("sqlops","sqlcon","secdb=>mysql://root:@192.168.1.231/db_table") /var/log/messages Jun 26 06:16:00 test-ser /sbin/kamailio[20217]: ERROR:db_mysql:db_mysql_new_connection: driver error: Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2) Jun 26 06:16:00 test-ser /sbin/kamailio[20217]: ERROR:core:db_do_init: could not add connection to the pool Jun 26 06:16:00 test-ser /sbin/kamailio[20217]: ERROR:sqlops:sql_connect: failed to connect to the database [pridb] Jun 26 06:16:00 test-ser /sbin/kamailio[20217]: ERROR:core:init_mod_child: failed to initializing module sqlops, rank 1 Jun 26 06:16:00 test-ser /sbin/kamailio[20217]: ERROR:core:main_loop: init_child failed for UDP listener What is the proper way of using multiple database servers with Kamailio? Thanks in advance. --JR

[Kamailio-Users] new feature: execute mi commands via rpc
by Daniel-Constantin Mierla 30 Jun '09

30 Jun '09

Hello, there is a new module in repository that allow you to execute most of the mi commands from Kamailio modules (see readme) via RPC interface inherited from SER: http://sip-router.org/docbook/sip-router/branch/master/modules/mi_rpc/mi_rp… http://sip-router.org/docbook/sip-router/branch/master/rpc/ser_rpc.html One of the nicest things you can out of this is usage of sercmd - command line interface tool. It is located in utils/sercmd. Thanks to Andrei, sercmd does now tab completion for mi command. How to use it: - get sip router from git: git clone --depth 1 git://git.sip-router.org/sip-router cd sip-router make all - add to your config file: loadmodule "ctl.so" # located in 'modules_s' loadmodule "mi_rpc.so" # located in 'modules' - use sercmd cd utils/sercmd make ./sercmd Then you should get: sercmd> mi <tab><tab> arg nh_show_rtpp t_reply ul_rm_contact cleanup ps t_uac_cancel ul_show_contact debug pwd t_uac_dlg uptime dum refreshWatchers ul_add version kill shv_get ul_dump which nh_enable_ping shv_set ul_flush nh_enable_rtpp t_hash ul_rm sercmd> mi uptime 200 OK + Now:: Tue Jun 30 12:47:54 2009 + Up since:: Tue Jun 30 12:47:26 2009 + Up time:: 28 [sec] Via sercmd you can control lot of internals at runtime -- see 'help' command -- more about: http://git.sip-router.org/cgi-bin/gitweb.cgi?p=sip-router;a=blob_plain;f=ut… Enjoy, Daniel -- Daniel-Constantin Mierla http://www.asipto.com/
