[REQ,$] db_rest module for database access
by Konstantin Cherkasov 22 Jun '09

22 Jun '09

Hello! Our company seeking for programmer who can create module for flexible database access. I call it db_rest. This module must provide internal database API for other modules like db_auth. For access to external data it must use HTTPS-server and use REST-style data access (http://en.wikipedia.org/wiki/Representational_State_Transfer). Instead of making query like "SELECT f1,f2,f3 FROM tableA WHERE f4 = 'somevalue'" it must call HTTPS-server like this: GET http://hostname/database/tableA&c=f1,f2,f3&k=f4&op=eq&v=somevalue Server must return delimiter-separated data. Similarly (using POST) it must implement support for insert, update and so on. Of course we would like to see this module inside the main project repository. If you are interested please contact me for details (requirements, $$). -- Konstantin

[OT] SIP ALG Detector released
by Iñaki Baz Castillo 19 Jun '09

19 Jun '09

Hi, as part of my personal battle against SIP ALG routers, I've created an utility to detect such routers: http://dev.sipdoc.net/wiki/sip-stuff/SIP-ALG-Detector It has two parts: client and server: Basically, the client node running into the LAN sends an INVITE to the server node (running in a host with public IP). The request could be modified by the LAN router if SIP ALG is enabled. The server encodes the received request in Base64 and appends it to the SIP response. The client receives the response, decodes the body and gets the request as it arrived to the server. Then it creates a diff between the original request and the the request the server node received. These differences are displayed in the screen. Both, UDP and TCP, tests are performed. The client node is coded in Ruby and should work in any operating system (if Ruby is installed). The server node is also coded in Ruby. For those interested in try it, I have a server node running in my personal server: 87.98.230.161:5060 You can test the client against my server. Feedback is welcome :) Regards. -- Iñaki Baz Castillo <ibc(a)aliax.net>
