Re: [Serusers] Windows to Linux

I am probably not the best person to ask that, since I have been brute forcing my way through - i.e. reading and debugging code without consulting a manual. There are tons of resources on the net for coding in C and since you already have 3 years of experience I am sure that moving to ANSI C won't be too hard. If you have coded in JAVA or C++ then it should be a breeze. If anything you should read up on pointers and memory allocation, because those two seem to catch most new coders the most. The GDB suggestion is also excellent. I have found it to be one of the most useful debugging tools that I have ever used since it gives a nice stack backtrace with line numbers etc. good luck, Zach Keatts Software Engineer Nuvio.com viquar syed wrote: > Hey Zach, > First off, thanks for your reply.

[Serusers] Windows to Linux
by viquar syed 30 Sep '05

30 Sep '05

Hi, My company wants me to hop on to Linux/Unix from Bill Gates, and to make it even better I am suppose to get upto speed writing modules to enhance our SER deployment. What experience do I have writing in ANSI C "0", "ZERO", "nada", BUT, I have been programming for over three yrs now so the logic is not an issue. My question, whats the best way to start, I am currently going through the documentation on SER Admin, need to have a plan. I know no one likes newbees, but hey any help would be highly appreciated. Thanks Viq

HI, first: please (CC) the mailing list in order to others can see answers. Try enable logging in serweb (config variable $config->enable_loging = true) and see the log file. There are more descriptive errror messages. You may also try set log level to debug.

[Serusers] ser web
by Elad Dotan 30 Sep '05

30 Sep '05

Hi, I've installed 4 RPM files on a Fedora CORE 3. The RPM are: ser-0.9.3-0.i386.rpm php-pecl-classkit-0.4-2.i386.rpm ser-mysql-0.9.3-0.i386.rpm serweb-0.9.3-0.i386.rpm I enabled the httpd and mysql service. I'm not sure what to do next. All the Documentation I have is related to source flies and not RPM. Ser is working but I don't know how to configure the serweb in order for it to work. I tried: http:// but I get an error. where can I find documentation about ser web? Thanks, Elad.

[Serusers] Branch result code selection during serial forking - OpenSER does it?
by Arek Bekiersz 30 Sep '05

30 Sep '05

Hi, I've once asked Serusers list about problem with sequential forking and failure_routes[]. SER pickes lower result code from branches. This is how "tm" module is done (t_check_status(), ...). Mail was from 05 September 2005, titled: "t_check_status() - why it is checking for winning reply in failure_routes?" Received many answers, thanks for it. I was responded by Klaus Darilion on 06/09 that SER policy is kept according to RFC - we pick LOWEST response code. So it is impossible in example to make sequential (serial) routing based on "486" to third branch, when first branch responded "404" and second branch responded "486". There will always be "404". I was thinking yesterday about writing just another alternative function for t_check_status() and t_pick_branch() in tm module, to do what I need. That is: checking if error code is something useful, that tells me what happened downstream in current branch (busy? timed out?). But today I was reading this article on OpenSER: http://openser.org/pipermail/users/2005-June/000004.html Seems it is possible to use OpenSER to make sequential forking with more than one failure_route[]? There is fix to tm module that pickes result only from last set of forked branches? Am I correct? Thanks for comments. -- Regards, Arek Bekiersz

When I installed both freeradius 1.0.4 and radiusclient 0.4.3 on the same server which ser 0.8.14 has installed on, I could log in X-lite through radius authorization. And now I want radiusclient (on server A) to send the request to a remote radius server (on server B) to realize authorization. I have changed those config files: /usr/local/etc/radiusclient/servers, /usr/local/etc/radiusclient/radiusclient.conf and /usr/local/etc/raddb/clients.conf as the document (http://www.iptel.org/ser/doc/ser_radius/ser_radius.html#AEN193) did.

[Serusers] No accounting records logged by radius in mysql; Unsupported Acct-Status-Type = 15
by Cameron Beattie 30 Sep '05

30 Sep '05

I have configured ser with radius accounting and I see accounting records being generated successfully in the file system. I have also configured accounting to mysql. Successful calls are logged to mysql correctly but unsuccessful calls are not. When I run radius -X and watch what happens I see the following: rlm_sql (sql): Unsupported Acct-Status-Type = 15 modcall[accounting]: module "sql" returns noop for request 1 dictionary.ser contains the following line: VALUE Acct-Status-Type Failed 15 # RFC2866, acc I have added the contents of dictionary.ser to the radiusclient/dictionary and radiusclient-ng/dictionary files. I have included dictionary.ser in raddb/dictionary. I'm sure there's a configuration step I've missed. Could anyone suggest some other things to check? Thanks Cameron
