[OpenSER-Users] Bigger OpenSER installation (2-5 Mio subs) and High Availability
by Adrian Georgescu 29 Apr '08

29 Apr '08

Hi Peter, If you care for a comercial solution that scales linearly with the amount of hardware without using any load balancers here is one: http://www.ag-projects.com/SIPThor.html Regards, Adrian >>>>>>>>>>>>>>> Hello, I have done a project for a SIP provider who is rapidly growing. Designed as a SBC for about 50.000 subscribers at first, I setup a system with a high availability cluster (HA/DRBD) on 2 servers which had one single database on the DRBD volume. Failover works like a charm with only very limited downtime. Now we have to consider to scale the system to about 2-5 Mio subs, so I have to challenge with some things I cannot oversee at the moment. My question is: How do you deal with big installations? - how do you load balance the openser? Is it advisable put put some dedicated SIP hardware in front for load balancing? Or is the dispatcher module on a seperate machine sufficiant (again HA-issue)? - we have a portion of calls who have to go through mediaproxy (How do you load balance this?) - Do you face database issues? We think about setting up a database on 2 seperate servers. Is MySQL ok for this or do you use other DBMS? - Form your exoperience: Are there other things I have to consider? Best regards and thanks for your support. Peter

Hi, I tried to find the patch "replace_from.patch" for the UAC module in the "/module/uac/doc" path but it isn't there. Is there any change about this information or is the UAC module not longer supported in SER 2.0.0-rc1? Regards Alberto Cruz

[OpenSER-Users] IPv6 issues in openser
by Klaus Darilion 28 Apr '08

28 Apr '08

Hi! Following some IPv6 issues: 1) I configured openser (1.3.0) to listen on an IPv6 address too: listen = udp:[2001:7b8:2ff:1da::2]:5060 listen = tcp:[2001:7b8:2ff:1da::2]:5060 I also configured bind9 and apache2 to listen on this IPv6 address. But somehow openser does it different then others: # netstat -anp|grep 2001 tcp6 0 0 2001:7b8:2ff:1da:::5060 :::* tcp6 0 0 2001:7b8:2ff:1da::2:80 :::* tcp6 0 0 2001:7b8:2ff:1da::2:53 :::* udp6 0 0 2001:7b8:2ff:1da::2:53 :::* udp6 0 0 2001:7b8:2ff:1da:::5060 :::* As you see, openser binds to [2001:7b8:2ff:1da::] whereas others binds to [2001:7b8:2ff:1da::2]. Actually this didn't caused any problems, but I still surprised about the difference. Can someone explain me please this behavior? 2) I found out that openser allows this syntax too (without []). listen = udp:2001:7b8:2ff:1da::2 I think it would be better to disallow that syntax and require [] as it is ambiguous when specifying the port too, e.g.: listen = udp:2001:7b8:2ff:1da::2:5060 3) Looks like the syntax in the socket column of the location table is not IPv6 compatible: ERROR:usrloc:parse_phostport: too many colons in udp:2001:7B8:2FF:1DA:0:0:0:2:5060 ERROR:usrloc:dbrow2info: bad socket <udp:2001:7B8:2FF:1DA:0:0:0:2:5060> ERROR:usrloc:preload_udomain: sipping record for klaus1 in table location I guess the socket should use [] for IPv6 addresses too. regards Klaus

[OpenSER-Users] Tie BYE to INVITE?
by Douglas Garstang 28 Apr '08

28 Apr '08

Is there a way I can tie a BYE to an INVITE? The setflag() and isflagset() commands only work on a transaction, right? And, a BYE is a new transaction, so how could I tell if a BYE is related to a previous INVITE?

[OpenSER-Users] SIGILL when starting openser
by Christian Koch 28 Apr '08

28 Apr '08

Hi, when starting openser 1.3.1 it doesn't really start, but stops after processing a SIGILL. When perfoming strace -f /usr/local/sbin/openser I get the following output (these are only the last few lines): time([1208951399]) = 1208951399 stat64("/etc/localtime", {st_mode=S_IFREG|0644, st_size=837, ...}) = 0 stat64("/etc/localtime", {st_mode=S_IFREG|0644, st_size=837, ...}) = 0 stat64("/etc/localtime", {st_mode=S_IFREG|0644, st_size=837, ...}) = 0 send(3, "<143>Apr 23 13:49:59 /usr/local/"..., 147, MSG_NOSIGNAL) = 147 --- SIGILL (Illegal instruction) @ 0 (0) --- Process 12746 detached I've compiled openser from source on the same machine. When starting openser with -V everything works just fine. Output: version: openser 1.3.1-notls (i386/linux) flags: STATS: Off, USE_IPV6, USE_TCP, DISABLE_NAGLE, USE_MCAST, SHM_MEM, SHM_MMAP, PKG_MALLOC, F_MALLOC, FAST_LOCK-ADAPTIVE_WAIT ADAPTIVE_WAIT_LOOPS=1024, MAX_RECV_BUFFER_SIZE 262144, MAX_LISTEN 16, MAX_URI_SIZE 1024, BUF_SIZE 65535 poll method support: poll, epoll_lt, epoll_et, sigio_rt, select. svnrevision: unknown @(#) $Id: main.c 3590 2008-01-28 17:46:56Z bogdan_iancu $ main.c compiled on 10:47:24 Apr 23 2008 with gcc 3.4.5 So I guessed the problem could occur inside a module. I removed auth.so and auth_db.so from my config file, but openser still doesn't start. But, it doesn't receive a SIGILL anymore, but SIGTERM.

[OpenSER-Users] ERROR:presence:mod_init: Wrong version v-1 for table <presentity>, need v2
by Andrea Polidoro 28 Apr '08

28 Apr '08

Dear all, I'm trying to install in a debian sid machine the openser 1.3 in order to use it as presence server. I downloaded the openser and the presence module from the official debian repository. As database I'm using mysql. Unfortunately, when I try to start the openSer I receive this error: "ERROR:presence:mod_init: Wrong version v-1 for table <presentity>, need v2" I found the presentity table structure in this link: http://www.openser.org/docs/db-tables/openser-db-1.3.x.html#GEN-DB-PRESENTI… and I compared it with the presentity table in my system (this is the output): mysql> describe presentity; +---------------+------------------+------+-----+---------+----------------+ | Field | Type | Null | Key | Default | Extra | +---------------+------------------+------+-----+---------+----------------+ | id | int(10) unsigned | NO | PRI | NULL | auto_increment | | username | varchar(64) | NO | MUL | NULL | | | domain | varchar(64) | NO | | NULL | | | event | varchar(64) | NO | | NULL | | | etag | varchar(64) | NO | | NULL | | | expires | int(11) | NO | | NULL | | | received_time | int(11) | NO | | NULL | | | body | blob | NO | | NULL | | +---------------+------------------+------+-----+---------+----------------+ 8 rows in set (0.03 sec) How you can see, they seam identical. I searched this error in your mailing list but I didn't find anything. Please, could you help me to understood witch is the error? the presence parameters in my openser.cfg are: modparam("presence", "db_url", "mysql://openser:openserrw@127.0.0.1/openser") modparam("presence", "presentity_table", "presentity") modparam("presence", "server_address", "sip:192.168.100.22:5060") Thank you in advance for your help, Best Regards Andrea Polidoro -- ******************************************** Andrea Polidoro PhD Student University of Rome "Tor Vergata" Department of Electronics Engineering Via del Politecnico, 1 - 00133 Rome - ITALY phone: +39 06 7259 7773 mobile: +39 320 4391892 email: andrea.polidoro(a)uniroma2.it ********************************************

[OpenSER-Users] Global variables in scripts.
by Peter Lemenkov 28 Apr '08

28 Apr '08

Hello All! Are any ways to define global variables in openser's scripts? I need somethng like ========================================== $var(router1) = "192.168.1.1" $var(router2) = "192.168.1.2" route { ... myfunc1("$ru") switch($retcode) case 1: $ruri = "sip:" + $rU + "@" + $var(route1); case 2: $ruri = "sip:" + $rU + "@" + $var(route2); } failure_route[1] { myfunc2("$ru") switch($retcode) case 1: $ruri = "sip:" + $rU + "@" + $var(route1); case 2: $ruri = "sip:" + $rU + "@" + $var(route2); } onreply_route[1] { myfunc3("$ru") switch($retcode) case 1: $ruri = "sip:" + $rU + "@" + $var(route1); case 2: $ruri = "sip:" + $rU + "@" + $var(route2); } ========================================== Right now (AFAIK) variables may be defined only within one route. Maybe I missing something? What's the scope of visibility of variables within configuration script? -- With best regards!
