I think this is a limitation from mysql, look for example to this bug: http://bugs.mysql.com/bug.php?id=4541 The openserdbctl script failed to detect that your server uses UTF-8 as default charset, because there was an error present in the tool. This is fixed now, it should now work for you regardless if you use latin1 or utf8 as default charset. Cheers, Henning

[OpenSER-Users] NAT problem in bridging mode
by Christian Koch 21 May '08

21 May '08

Hi, I have a problem with openser and rtpproxy. I'm trying to use them as a gateway between the public internet and a LAN. Clients in the internet may be natted, so I'm using nathelper. Calls are only made from LAN to outside or vice versa, but not from LAN to LAN or from outside to outside. The following should illustrate my configuation: ----- ------------------ UAC1 --- | NAT | ------------- | OpenSER/rtpproxy | ----------------UAC2 ----- ------------------ | | | | | dynamic public IP 2.3.4.5 192.168.103.121 192.168.103.189 (e.g. 1.2.3.4) UAC1 and UAC2 are both registered at OpenSER. Now I'm making a call from UAC1 to UAC2. SIP messages are passed just fine, but the RTP traffic from UAC2 to UAC1 is dropped at the NAT. I used tcpdump on the OpenSER/rtpproxy machine to figure out what happens to RTP and it shows the following (ports and IPs are just examples): stream1: 1.2.3.4:10000 -> 2.3.4.5:35000 ->RTP is forwarded by rtpproxy-> 192.168.103.121:35000 -> 192.168.103.189:11000 stream2: 1.2.3.4:20000 <- 2.3.4.5:35000 <-RTP is forwarded by rtpproxy<- 192.168.103.121:35000 <- 192.168.103.189:11000 Port 20000 in stream2 is the RTP-port used internally by UAC1 behind the NAT (this port is found in the INVITE from UAC1 to OpenSER). I understand, that rtpproxy sends the first packets to port 20000. But, after receiving some packets from port 10000, shouldn't it change the destination port to 20000 so they can pass the NAT? rtpproxy is started like this: "./rtpproxy -l 192.168.103.121/2.3.4.5 -f ". It produces the following output: [root@192 rtpproxy]# /usr/local/bin/rtpproxy -l 192.168.103.121/2.3.4.5 -f rtpproxy started, pid 22125 received command "UIE 9D740CB7-18A4-40B2-A96D-13FC3C5B27D3(a)192.168.103.189 192.168.103.189 49156 207860870326595;1" new session 9D740CB7-18A4-40B2-A96D-13FC3C5B27D3(a)192.168.103.189, tag 207860870326595;1 requested, type strong new session on a port 35000 created, tag 207860870326595;1 pre-filling caller's address with 192.168.103.189:49156 sending reply "35000 2.3.4.5 " received command "L 9D740CB7-18A4-40B2-A96D-13FC3C5B27D3(a)192.168.103.189 1.2.3.4 49154 207860870326595;1 5364140283;1" lookup on ports 35000/35000, session timer restarted pre-filling callee's address with 1.2.3.4:49154 sending reply "35000 192.168.103.121 In my openser.cfg I'm not really checking wheter a client is really natted, but I think it shouldn't be a problem to assume, that all clients are behind a NAT?

Hi, I am hoping someone can help me our with associating user with group in openser. If I use the command line: Question 1: debian:/home/ser# openserctl acl grant 1006 LD WARNING: Invalid privilege: acl 'LD' ignored debian:/home/ser# What is wrong with the syntax? Question 2: If I use sermyadmin to associate user to groups, I get the following error: org.codehaus.groovy.runtime.InvokerInvocationException: org.springframework.dao.DataIntegrityViolationException: could not insert: [UserGroup]; nested exception is org.hibernate.exception.ConstraintViolationException: could not insert: [UserGroup] at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:290) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.apache.catalina.core.ApplicationDispatcher.invoke(ApplicationDispatcher.java:630) at org.apache.catalina.core.ApplicationDispatcher.processRequest(ApplicationDispatcher.java:436) at org.apache.catalina.core.ApplicationDispatcher.doForward(ApplicationDispatcher.java:374) at org.apache.catalina.core.ApplicationDispatcher.forward(ApplicationDispatcher.java:302) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:235) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:235) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:235) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:235) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.jsecurity.web.servlet.WebInterceptorFilter.doFilterInternal(WebInterceptorFilter.java:106) at org.jsecurity.web.servlet.SecurityContextFilter.doFilterInternal(SecurityContextFilter.java:93) at org.jsecurity.web.servlet.OncePerRequestFilter.doFilter(OncePerRequestFilter.java:106) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:235) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:233) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:175) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:128) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:286) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:844) at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:583) at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:447) at java.lang.Thread.run(Thread.java:595) Caused by: org.springframework.dao.DataIntegrityViolationException: could not insert: [UserGroup]; nested exception is org.hibernate.exception.ConstraintViolationException: could not insert: [UserGroup] at UserController$_closure6_closure11.doCall(UserController.groovy:111) at UserController$_closure6.doCall(UserController.groovy:101) at UserController$_closure6.doCall(UserController.groovy) ... 29 more Caused by: org.hibernate.exception.ConstraintViolationException: could not insert: [UserGroup] at $Proxy3.saveOrUpdate(Unknown Source) ... 32 more Caused by: com.mysql.jdbc.exceptions.MySQLIntegrityConstraintViolationException: Duplicate entry '1005-192.168.1.104-' for key 2 at com.mysql.jdbc.SQLError.createSQLException(SQLError.java:1011) at com.mysql.jdbc.SQLError.createSQLException(SQLError.java:956) at com.mysql.jdbc.MysqlIO.checkErrorPacket(MysqlIO.java:3491) at com.mysql.jdbc.MysqlIO.checkErrorPacket(MysqlIO.java:3423) at com.mysql.jdbc.MysqlIO.sendCommand(MysqlIO.java:1936) at com.mysql.jdbc.MysqlIO.sqlQueryDirect(MysqlIO.java:2060) at com.mysql.jdbc.ConnectionImpl.execSQL(ConnectionImpl.java:2542) at com.mysql.jdbc.PreparedStatement.executeInternal(PreparedStatement.java:1734) at com.mysql.jdbc.PreparedStatement.executeUpdate(PreparedStatement.java:209) at com.mysql.jdbc.PreparedStatement.executeUpdate(PreparedStatement.java:1937) at com.mysql.jdbc.PreparedStatement.executeUpdate(PreparedStatement.java:1922) at org.apache.tomcat.dbcp.dbcp.DelegatingPreparedStatement.executeUpdate(DelegatingPreparedStatement.java:102) ... 33 more What is wrong with my setup of sermyadmin?

[OpenSER-Users] UDP Buffer Size / OpenSER / Linux
by Carsten Bock 21 May '08

21 May '08

Hi, short question: Can anybody give me a hint regarding the Linux UDP-Buffer size? Are there any known good values for this or is the default value (128k) of Linux sufficient? I've read, regarding other SIP-Systems (namely IBM SIP Servlets and Communigate pro), the recommendation to increase the UDP-Buffer-size to 3 or even 4 MByte.... Are there any recommended / known best values for heavy load OpenSER Installations? Thanks in advance, Carsten Reference: http://publib.boulder.ibm.com/infocenter/wasinfo/v6r1/index.jsp?topic=/com.…

[OpenSER-Users] Why can't I "append_branch()" in FAILURE_ROUTE if reply is 6XX ??
by Iñaki Baz Castillo 21 May '08

21 May '08

Hi, when I receive a 480 or 603 from a local user I run "on_failure_route" and create new branch to forward the INVITE to a media server in which I reply an early-media "The number you are calling is not available now...". It works perfectly if the error is 4XX but it doesn't work if it's a 6XX. I get this error: --------------------- ## onreply_route[ON_REPLY_TO_USER]: 603: Decline ## failure_route[ON_FAILURE_TO_USER] --- TO_MEDIA_SERVER: Destino user_not_available May 21 12:25:25 [8502] ERROR:tm:t_forward_nonack: discarding fwd for a cancelled/6xx transaction May 21 12:25:25 [8502] ERROR:tm:w_t_relay: t_forward_nonack failed ---------------------- My code is very simple: ---------------------- failure_route[ON_FAILURE_TO_USER] { if (t_check_status("480|603")) { $rU = "user_not_available"; route(ROUTE_TO_MEDIA_SERVER); exit; } } route[ROUTE_TO_MEDIA_SERVER] { rewritehostport("MEDIA_SERVER_IP:MEDIA_SERVER_PORT"); append_branch(); t_relay(); } --------------------- It seems that if the reply is a 6XX then OpenSer can't generate a new_branch in failure_route. May 21 12:25:25 [8502] ERROR:tm:t_forward_nonack: discarding fwd for a cancelled/6xx transaction Why? doesn't it make sense to forward to some destination even if the negative reply is a 4XX or 6XX?
