[Serusers] loose routing problem
by Klaus Darilion 26 Feb '04

26 Feb '04

Hi! Once again I'm stucked in the loose routing topic, maybe some can answer my question! I have ser configured to use RR. At the top of my ser.cfg I have: # loose-route processing log(1, "check loose_route ..."); if (loose_route()) { log(1, "loose_route processing, finished routing!\n"); t_relay(); break; }; log(1, "no loose_route processing\n"); ... Client A is xlite, which is a loose router, and Client B is Windows Messenger 4.7, which is a strict router. One client calls the other client, which accepts the call. Then the client hangs up. If client A hangs up (xlite, loose router) the loose_route(){...} block will not be processed and the BYE is handled by the following routing logic. If client B (strict router) hangs up, the loose_route(){...} block will be executed. So, why is the request from xlite (loose router) not treated in the loose_route block? IMHO, I would suggest that both requests (loose and strict) should be handled be the loose_route block. Also RFC3261 (16.4) says that "strict router" request should be transformed into a loose routing request (writing the last Route header field into the req-URI and remove this route header field) and than be handled like all other requests. Maybe I've missed something. Regards, Klaus

btw: I didn't tried the setup with serial cable and a dedicated NIC for heartbeat as described in the hearbeat howto. I just had one NIC inside the PCs which was also used for heartbeat. klaus Arnd Vehling wrote: > nope, havent tried it yet. I am waiting for 2 new 1U rack boxes > for testing it with.

[Serusers] proper way of installation for SER with MYSQL
by Ansari, Fahriz 26 Feb '04

26 Feb '04

Hi, I have already installed SER 0.8.9. Now I want to install 0.8.12 with MYSQL. Is there anybody who can send me information for sequence of operations I have to do to perform this uninstall (0.8.9) and install (0.8.12). What I have to do on SER machine and what I have to do on MYSQL machine. Thanks, Fahriz Aqeel Ansari, Telogy Inc, MD, USA.

[Serusers] debian question
by Klaus Darilion 26 Feb '04

26 Feb '04

Hi! The question a little bit off topic, but I'm sure you canhelp me :-) Usually, I used Redhat, but as they stopped their free update service, I'm looking for a new platform. In older postings, most people recommend debian, that's why I want to give it a try. The debian homepage tells me, that security updates will only be available for the stable release, so I wanted to use stable. But stable does not support mysql 4, which is required for serweb. So, what are your common practices to overcome such problems (the trade off between stable/old software and unstable/new software)? Do you use Debian testing? Do you use just the base packages on stable and compile mysql 4 yourself? Do you use backports or do you mix stable/testing? thanks, Klaus

Check out this method. http://www.presttun.org/kare/DNS/DNS-LB-FT.pdf It's designed for HTTP requests, but I don't see any reason that it couldn't be used for SER as well.
