[Serusers] Crash in SER
by Maxim Sobolev 21 Feb '03

21 Feb '03

Hi, We've observed the following crash in ser. Do you have any ideas what the cause could be? I'm keeping corefile and binary compiled with debug symbols, so that don't hesitate to contact me if any additional information is necessary. Thank you in advance! -Maxim Script started on Fri Feb 21 05:43:09 2003 bash-2.05a$ gdb ~/sip/ser/work/ser-0.8.10/ser ser.core GNU gdb 4.18 (FreeBSD) Copyright 1998 Free Software Foundation, Inc.

[Serusers] problem with loading compiled radius modules
by Benny Ho 21 Feb '03

21 Feb '03

I had the same error msgs when I load the radius_acc modules the following is the error msgs [root@md benny]# /usr/sbin/ser restart 0(3699) ERROR: load_module: could not open module </usr/lib/ser/modules/radius_ acc.so>: libradiusclient.so.0: cannot open shared object file: No such file or d irectory 0(3699) parse error (25,13-48): failed to load module ERROR: bad config file (1 errors) [root@md benny]# and I check that the radius_acc.so is in /usr/lib/ser/modules and the libradiusclient.so.0 is also in /usr/local/lib as it is stated in the Makefile. Where is the error came from? Have any one successfully implement it?

[Serusers] RE: RE: problem with loading compiled radius modules

Hi Benny, I had the same problem as you. After I statically linked the radiusclient library in the both radius modules this problem seems to be resolved. http://lists.iptel.org/pipermail/serusers/2003-February/000419.html However radius authentication still doesn't work and the developer said: "the path is not staticaly linked, it should be resolved by you dynamic linker, I don't know where is the problem, it seems to me that there is some problem with radiusclient libraries on your system, " I use Solaris 8. Now I am trying to recompile and reinstall radiusclient library. If I find out something, I'll tell you. regards, yang

MSG_EOR is used to indicate a record mark for protocols which support the concept. MSG_EOF requests that the sender side of a socket be shut down, and that an appropriate indication be sent at the end of the specified data; this flag is only implemented for SOCK_STREAM sockets in the PF_INET protocol family, and is used to implement Transaction TCP (see ttcp(4)). MSG_DONTROUTE is usually used only by diagnostic or routing programs. --- Lenny Tropiano E-mail: lenny(a)voiping.com Partner, Networking Specialist Pager: pager-lenny(a)voiping.com VoIPing, LLC URL: http://www.voiping.com/ PO Box 867, Cedar Park, TX 78630-0867 Mobile: 512-698-VOIP [8647]

[Serusers] Via tags question...
by lgfausak＠august.net 20 Feb '03

20 Feb '03

This is a protocol question, I don't know if it is directly related to ser. Concerning the Via tags, should any proxy/gateway modify tags that don't belong to it, or should they simply be copied verbatum? For example, I have a situation where I send an INVITE message, and the TRYING response I receive modifies one of the Via: tags. I don't think this is right. Here are the two packets in question: # U 2003/02/19 18:36:20.276844 164.9.42.25:5060 -> 184.294.324.2:5060 INVITE sip:12143357976@184.294.324.2:5060 SIP/2.0. Max-Forwards: 10.

Hi, I would add a user to subsriber table by sql command in my application (not using serctl script). What text strings I must use to calculate HA1 (=phplib_id) and ha1b values if USER_ID=ivan,PASSWORD=ivanpswd and REALM=192.168.11.237 ? Thanks in advance.

Hi again, Here is how to get a segfault: <snip> #Load modules required by a stateful User Agent Service loadmodule "modules/tm.so" #SER timer parameters modparam("tm", "fr_inv_timer", "10"); modparam("tm", "fr_timer", "10"); </snip> This happened after quoting the numbers in the modparam.

[Serusers] Logging with SER
by Sebastien Pierre 19 Feb '03

19 Feb '03

Hi all, I finally found solutions to my problem: 1) It is easier when setting "fork=no" because then ser does not daemonise and stderr is then attached to the terminal in which I started ser 2) The configuration file should set a debugging level ("set debug=1"), and use a number equal or lower to the debug level in the log, like 'log(0, "Hello World")' So my HelloWorld.cfg is as follows: <snip> debug=0 log_stderror=yes fork=no route[0] { log(0, "Hello World!"); } </snip> And it works with "ser -f HelloWorld.cfg" Cheers, -- Sebastien
