by Liu Wenlong 07 Mar '08

07 Mar '08

I compiled & installed ser-0.9.7. But cannot start it. The Log is: 0(28624) loading module /usr/local/lib/ser/modules/acc.so 0(28624) ERROR: load_module: could not open module </usr/local/lib/ser/modules/acc.so>: /usr/local/lib/ser/modules/acc.so: undefined symbol: parse_orig_uri 0(28624) parse error (41,13-14): failed to load module 0(28624) set_mod_param_regex: No module matching acc found | 0(28624) parse error (43,19-20): Can't set module parameter 0(28624) set_mod_param_regex: No module matching acc found ... And in compiling log, there is a acc.c:291: warning: implicit declaration of function 'parse_orig_uri' it seems that I lost some devel packages. who can tell me in which package defined "parse_orig_uri"? My OS is CentOS 5.1 x64 Thank you very much! Liu Wenlong -- aRES iN aNYWhere

Re: [OpenSER-Users] issue - remote sip client must re-register after failover in Openser Registrar HA config
by Naija Man 07 Mar '08

07 Mar '08

Thanks Patrick, I have re-configured a common database for the servers and I am still having the same issues. Can this be an issue with PAT at the Load balancer after failover since the INVITE is coming from openser_2 and going to the same IP:port associated with openser_1. I am also open to trying other methods to achieve OpenSER registrar HA if any available. Thanks.

[OpenSER-Users] ERROR:core:main: bad user name/uid number: -u openser
by bsb093 07 Mar '08

07 Mar '08

Hi all, I am still trying to run OpenSER. Now I see the following error: ERROR:core:main: bad user name/uid number: -u openser I am trying to install version 1.3 with MySQL. I have succeeded to create the db but when trying to run OpenSER I still have this error. I have found in the forum that maybe I don't have openser user in /etc/passwd and that is true but I can't figure how to create that user. Any suggestions? Thanks in advance, Shine -- View this message in context: http://www.nabble.com/ERROR%3Acore%3Amain%3A-bad-user-name-uid-number%3A--u… Sent from the OpenSER Users Mailing List mailing list archive at Nabble.com.

Re: [Serusers] General Question on BYE

Thanks Greger. I set debug to 9 and found the BYE inside the log file. It was seen by SER. Now I have a trail on the culprit. ..mike..

In the past I experienced "bad performance" using unixsoctrl with medium load so I think it's worth making users moving to new interfaces. vote for removing it samuel. 2008/3/7, Juha Heinanen <jh(a)tutpro.com>: > > Raphael Coeffic writes: > > > - reduces configuration and run-time complexity > > > this proved to be true. my openser configuration became much simpler > when i migrated it from unixsockets to sip. > > > -- juha > > _______________________________________________ > Sems mailing list > Sems(a)lists.iptel.org > http://lists.iptel.org/mailman/listinfo/sems >

[OpenSER-Users] How to access pseudovariables in exported functions?
by Peter Lemenkov 07 Mar '08

07 Mar '08

Hello All! I need to put more than 2 parameters in my module, and there are pseudovariables among them. If I find a way to access them within my function then two parameters will be enough. Namely I need to access $fU, $tU and $rU. Using parse_headers function I can only get $fu, $tu and $ru. -- With best regards!

[OpenSER-Users] ERROR: presence_xml:get_final_notify_body?
by KevinKinnan 07 Mar '08

07 Mar '08

My testbed is combination of openser and openxcap. openser.cfg file is similar with the example on the website of OpenXCAP. After updating published information by sending PUBLISH, no NOTIFY message is sent to client-side. I got the following errors(debug=3) in syslog file. Any ideas anyone? --------------------------------------------------------------------------------------- ERROR:presence_xml:get_final_notify_body: while extracting the transformation node ERROR:presence_xml:pres_apply_auth: in function get_final_notify_body ERROR:presence:send_notify_request: in function apply_auth_nbody ERROR:presence:notify: sending Notify not successful ERROR:presence:publ_notify: Could not send notify for presence --------------------------------------------------------------------------------------- Regards, Kevin _________________________________________________________________ 手机也能上 MSN 聊天了，快来试试吧！ http://mobile.msn.com.cn/

[OpenSER-Users] CANCEL with Route headers
by Andreas Granig 07 Mar '08

07 Mar '08

Hi all, I've a Cisco PGW interconnecting with an OpenSER server. The INVITE is sent to OpenSER, which does some record-routing via some different hops and then sends back the 180 from the called party. If the calling party now cancels the call, the PGW tries to loose-route the CANCEL by adding the Route header to the CANCEL and altering the R-URI, which is rejected by my OpenSER since I don't allow initial loose-routing. So the question is: is it valid for a CANCEL to carry a Route header which wasn't available in the INVITE? §9.1 of RFC3261 says it MUST contain the Route header if it was present in the request being cancelled. What about the other way around? I heavily suspect it's violating the RFC since CANCEL should be more or less a 1:1 copy of the INVITE, but can anyone confirm this? If it violates the RFC, anyone with some Cisco knowledge who knows how to disable this behavior, or is it a known bug? Cheers, Andreas
