[Serusers] ser_ctl - connection refused

Hi, I'm using ser_ctl as follows: ser_ctl -g -s http://localhost:2046 ps but get the following error: Traceback (most recent call last): File "/usr/local/bin/ser_ctl", line 19, in ? main(sys.argv) File "./serctl/main.py", line 173, in main return call(func, args, opts) File "./serctl/main.py", line 115, in call return apply(func, args, opts) File "./serctl/ctlctl.py", line 235, in ps ret = rpc.core_ps() File "./serctl/ctlrpc.py", line 195, in core_ps ps = self.ser.core.ps() File "/usr/lib/python2.3/xmlrpclib.py", line 1029, in __call__ return self.__send(self.__name, args) File "/usr/lib/python2.3/xmlrpclib.py", line 1316, in __request verbose=self.__verbose File "./serctl/serxmlrpc.py", line 132, in request self._http_request(uripath, body, host) File "./serctl/serxmlrpc.py", line 104, in _http_request self.conn.request("POST", uripath, body, headers) File "/usr/lib/python2.3/httplib.py", line 718, in request self._send_request(method, url, body, headers) File "/usr/lib/python2.3/httplib.py", line 739, in _send_request self.endheaders() File "/usr/lib/python2.3/httplib.py", line 712, in endheaders self._send_output() File "/usr/lib/python2.3/httplib.py", line 597, in _send_output self.send(msg) File "/usr/lib/python2.3/httplib.py", line 564, in send self.connect() File "/usr/lib/python2.3/httplib.py", line 548, in connect raise socket.error, msg socket.error: (111, 'Connection refused') In my ser.cfg, I have: # unix sockets and fifo creation parameters modparam("ctl", "binrpc", "unix:/tmp/ser_ctl") # default modparam("ctl", "binrpc", "udp:10.10.90.51:2046") modparam("ctl", "binrpc", "tcp:10.10.90.51:2046") modparam("ctl", "binrpc", "unixd:/tmp/unix_dgram") # unix datagram modparam("ctl", "binrpc", "unixs:/tmp/unix_stream") # unix stream modparam("ctl", "binrpc", "unix:/tmp/unix_default") # unix stream modparam("ctl", "binrpc", "/tmp/unix_test") # unix stream modparam("ctl", "binrpc", "10.10.90.51:3000") # udp modparam("ctl", "binrpc", "tcp:3012") # tcp any , port 3012 modparam("ctl", "binrpc", "udp:*:3012") # udp any , port 3012 modparam("ctl", "fifo", "fifo:/tmp/ser_fifo") modparam("ctl", "mode", 0666) Any suggestions?

Hi, Thank you for your offer. I have already been able to compile the oracle module from ser. However even this module will not solve the issue of so many connections to DB. best regards g. > > Hi... > > I'm using an modified oracle module from ser dev implementation, it > lacks raw_query, fetch_result and replace functions and needs more > testing as well. > > I Was waiting to have time to finish it before to send to the tracker, > but if you want to give it a try, i could send it to you. > > I havent tested it for memory leaks, so its possible to have. > > It's pretty stable in our test environment, but i never tested with a > high load. > > Best regards > Disclaimer The information in this e-mail and any attachments is confidential.

Hi Christian, Our DB already has more than 100 connections from various other systems. Each connection takes about 5MB of memory. Since only 5 children are taking the heavy load, the rest 23 connections are mostly idle. And since we plan to have a second machine running Openser as a failover, there will be another 28 iddle connections. A single connection pool that would serve all children would be able to create connections on demand. At peak traffic it would be possible that the pool has as many connections as the number of children. But that would be rare (at least in our case). Basically, the amount of traffic would determine the amount of connections. What if each module opened the connection to the DB in mod_init() instead of child_init()? What implications could that have? Best regards George > Papadopoulos Georgios wrote: > ... > > Another issue that came up is the number of connections > from Openser to > > the database.

How do you write the listen directive? On my system, it looks like this: listen=udp:[2002:xxxx:xxxx::1:3]:15060 Regards, Bernard Chan.

[Users] Putting the OpenSER behind a load balancer which NATs
by Tim Madorma 14 Mar '07

14 Mar '07

Hi, I am going to put a pair of servers with OpenSER software on them behind a BIG IP load balancer which will use NAT to provide static IP addresses to each OpenSER server. In this case, when an incoming SIP Request is received, the destination IP address will differ from the host IP address defined in the Req URI (and To header). Is there any special configuration or a module that should be utilized to deal with this? thanks, Tim

[Users] DBTEXT performance vs. MySQL?
by Daryl Sanders 14 Mar '07

14 Mar '07

Hi Everyone, I am wondering if anyone here has experience with DBTEXT and can comment on it's performance vs. MySQL. I'm involved in a project where it makes sense to use DBTEXT at least for the subscriber table, but I need to know what performance problems I might face once the system is loaded with subscribers. For example, how many calls per second or minute might I expect to see? All comments are welcome. Thanks. - Daryl

[Users] SIP supplementary service
by 김형선 14 Mar '07

14 Mar '07

Hi. I saw the example script of openser.cfg for 'call forwarding'. Are other SIP supplementary services possible with OpenSER, by script? (call parking, call pickup, hold, conference, etc...) If it is possible, how can I get these script files? thanks 새로운 기부문화의 씨앗, 해피빈
