MYSQL and various
by Laura 12 Aug '18

12 Aug '18

Dear list, on my kamailio 4.4.7 i use interactions with MYSQL. For example .. i use it for some black list control and other like this.. sql_query("cb", "select id from blacklist where cli='$var(g2)' and (ippeer = '$si' or ippeer = 'ALL')", "rabl"); if($dbr(rabl=>rows)>0){ sql_result_free("rabl"); sl_send_reply("403","Forbidden blacklist"); exit; } sql_result_free("rabl"); I was wonder what was the best method to prevent the query going on if mysql don't respond for high load or other situation.. If Mysql is not able to reply to the query tight now the call continue over the configuration... what is the best way to prevent this and for examples drop it with a standard SIP 503 error. I have search on docs.. but i haven't found any valid way. Thanks Laura

problem with rewriteuri
by Eric Hosch 12 Aug '18

12 Aug '18

If I manually pass a string value to rewriteuri it works, but if I pass the same string from a database value it doesn't: if ($dbr(ra=>[0,4]) == "callfwd_noanswer") { $ does not work --> rewriteuri("$dbr(ra=>[0,6])"); works --> rewriteuri("sip:someone@somewhere"); append_branch(); route(0); Eric Hosch Chief Engineer KLBK-TV | KAMC-TV 7403 S.

by eyas barhouk 11 Aug '18

11 Aug '18

hello dears when i'm using kamailio 5.2 as IMS i'm facing the following NAT issue : * when p-cscf handle a call from user1 to user2 that pre-registered on private address "192.X.X.X" (on another LAN) the user can't receive the invite message . in another word: proxy ip : 10.192.X.X user1 ip : 10.X.X.X user2 ip : 192.X.X.X the call scenario : user1 ---invite----> user2 (not arrived) * when p-cscf handle a call from user2 that pre-registered on private IP "192.X.X.X" (on another LAN) to user1 the user receive the invite message . the call scenario : user2 ---invite----> user1 (arrived) * when both of the user on different LANs the message 200 OK doesn't arrive to proxy :\ so based on that does any one has an experiment with NAT handling & nathelper module and how to configure it on P-cscf . thanks in advance

UDP workers block when one or more rtpengine instances go offline
by Sebastian Damm 10 Aug '18

10 Aug '18

Hi, we run multiple rtpengine servers to share the load. Whenever we need to take an rtpengine server offline, we used to just block the control port via iptables, then no new calls ended up on this instance of rtpengine. This worked pretty well in Kamailio 4.4.5. However, since Kamailio 5.0, and the problem persists with 5.1.4, Kamailio hangs almost immediately after we block the control port traffic. In the log file there are almost no packets processed except every few seconds, which looks like a timeout thing. Did we configure anything wrong there? Or is the "dead rtpengine detection" just broken? Our configuration: loadmodule "rtpengine.so" modparam("rtpengine", "rtpengine_disable_tout", 120) modparam("rtpengine", "setid_avp", "$avp(rtpsetid)") modparam("rtpengine", "rtpengine_sock", "0 == udp:1.2.3.4:9001=2 udp:1.2.3.5:9001=2 udp:1.2.3.6:9001=2") modparam("rtpengine", "rtpengine_sock", "1 == udp:2.3.4.5:9001=2") Any help appreciated. Regards, Sebastian

kamcmd htable.reload propertiesHash problem
by Ginhoux, Patrick 10 Aug '18

10 Aug '18

Hi, I run Kamailio 5.0.1 with MariaDB database. There is no issue at the initialization, meaning the db is opened by kamailio and the hash tables loaded from the db tables. Example: # kamcmd htable.dump propertiesHash { entry: 1 size: 1 slot: { item: { name: cfg.env But the htable.reload command fails: error: 500 - Failed to open htable db connection The Kamailio log reports that it can't connect the db : DEBUG: ctl [../../core/io_wait.h:380]: io_watch_add(): DBG: io_watch_add(0x7f68c74ab300, 10, 3, 0xdc9410), fd_no=1 DEBUG: ctl [io_listener.c:442]: handle_new_connect(): handle_stream read: new connection (1) on /var/run/kamailio//kamailio_ctl DEBUG: <core> [core/sr_module.c:694]: find_mod_export_record(): find_export_record: found <db_bind_api> in module db_mysql [/usr/lib64/kamailio/modules/db_mysql.so] DEBUG: <core> [db.c:209]: db_bind_mod(): using db bind api for db_mysql DEBUG: <core> [db.c:314]: db_do_init2(): connection 0x7f68cc354c10 not found in pool DEBUG: db_mysql [km_my_con.c:98]: db_mysql_new_connection(): opening connection: mysql://xxxx:xxxx@/siprouter ERROR: db_mysql [km_my_con.c:124]: db_mysql_new_connection(): driver error: Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2 "No such file or directory") ERROR: <core> [db.c:318]: db_do_init2(): could not add connection to the pool ERROR: htable [ht_db.c:92]: ht_db_open_con(): failed to connect to the database My local db is located at /myqdata/mysiprdb/data where is the mysiprdb.sock file. But the log shows that Kamailio is looking for /var/lib/mysql/mysql.sock. Does this error make sense to you ? Is it possible to fix this problem by configuration in Kamailio ? My kamailio.cfg script contains : # ----- htable modparam("htable", "db_url", "mysql://[kamailio]/siprouter") modparam("htable", "fetch_rows", 1000) modparam("htable", "htable", "mbxrangeHash=>size=4;dbtable=mbxrange;") modparam("htable", "htable", "abpqHash=>size=12;dbtable=abpq;") modparam("htable", "htable", "zabpqHash=>size=12;dbtable=zabpq;") modparam("htable", "htable", "propertiesHash=>size=4;dbtable=properties;") In the /myqdata/mysiprdb/data/my.cnf, I added the following entries for Kamailio: [kamailio] socket = /myqdata/mysiprdb/data/mysiprdb.sock user = siprouter password = ########## default-character-set = utf8 Thanks all for help. Cordialement. Patrick GINHOUX

Re: [SR-Users] problem with compiling kamailio version 5.1.4 including a private Module
by Abdulaziz Alghosh 09 Aug '18

09 Aug '18

Hello Henning, thanks a lot for your response and explanation. strutils.[c,h] and strcommon.[c,h] are almost the same. So I modified my included header from stcommon[] to strutils as you mentioned. Unfortunately, I surfed sequentially Kamailio version upgrades. Even though, i did not found such hints about this modification. So I have some doubts the called headers and codes from our own module. Hence, I am asking for yor advice. What I am trying to do now is compiliing our module separately under it is own directory so I gain the Shared Object file (.so). Somehow our Module is requring cds, presence and xcap libraries. But the strange thing is that headers from these libraries are #including other headers assuming these included header files are under the same library's directory (but in fact most of the header files are under ../src/core/). For example : Making in cds CC (gcc) [L libser_cds.so.0.1] cds.o In file included from cds.c:2: /Abdul/install/clean_test/kamailio-5.1.4/src/lib/cds/../cds/memory.h:125:21: warning: mem/mem.h: No such file or directory /Abdul/install/clean_test/kamailio-5.1.4/src/lib/cds/../cds/memory.h:126:25: warning: mem/shm_mem.h: No such file or directory In file included from cds.c:3: /Abdul/install/clean_test/kamailio-5.1.4/src/lib/cds/../cds/sync.h:30:22: warning: locking.h: No such file or directory In file included from cds.c:4: /Abdul/install/clean_test/kamailio-5.1.4/src/lib/cds/../cds/logger.h:42:20: error: dprint.h: No such file or directory make[2]: *** [cds.o] Error 1 make[1]: [cds] Error 2 (ignored) Those libraries are delivered with version 5.1.4 itself so i do not think it is a good idea to modify the paths of the included header files to compile my module. because most probably these libraries are needed by standard default modules of kamailio. I hope this is not too much for you to inspect. Note: The attached has the log files ( resulting from make all and install ) .

problem with compiling kamailio version 5.1.4 including a private Module
by Abdulaziz Alghosh 09 Aug '18

09 Aug '18

Greetings, i am somehow newbie with Kamailio and trying to migrate from kamailio version 3.0.3 to 5.1.4. Former fellows had developed own modules which needed "strcommon.h" and "strcommon.c". These last two files are not delievered with version 5.1.4. but I copied them under ../src/core/ thinking it would be beneficial. Unfortunately, after make prefix / (and including our own module) all, it seem that several dependencies exist. Especially from header files under ..src/lib/xcap/ and ../src/lib/presence Can somebody tell me how "strcommon.h" and "strcommon.c" where replaced in version 5.1.4 ? Best regards Abdul Aziz

Questions about changes between 5.0.1 and 5.0.7
by Ginhoux, Patrick 08 Aug '18

08 Aug '18

Hi, Following a problem with the kamcmd htable.reload with Kamailio 5.0.1 (see related thread for this), I have upgraded to the 5.0.7 level (with some difficulties due to my specific environment). My server runs the RHEL 7.4 distribution. Now the upgrade is complete, I notice that that are changes not really documented: - The kamailio-perl-5.0.7-1.el7.x86_64.rpm requires to install the mod_perl module that doesn't exist anymore in RHEL 7. It needs to be installed from the EPEL repository - The init script for kamailio has been changed from the old method to the fully compliant method for system unit for RHEL 7 for example: With the 5.0.1 level we have the "/etc/rc.d/init.d/kamailio" With the 5.0.7 level we have now the "/usr/lib/systemd/system/kamailio.service" So my questions/comments are : - Why the mod_perl module is required between 5.0.1 and 5.0.7 (question posted in the attached message) ? - In the previous kamailo init script, I added a condition to start MySQL before kamailio by adding this entry in the script : # Required-Start: $syslog $network $mysqld The new script contains the After command : [Unit] Description=Kamailio (OpenSER) - the Open Source SIP Server After=network.target Should I change the After line with this : After=network.target mysql.target to have the same condition? In all the cases, some documentation must be changed to provide more details. Thanks in advance for the answers. Cordialement. Patrick GINHOUX
