Totally agreed, in fact my 1st thought was to try to abstract proxys code paths, but I left for new now the of the impact. My patch has a lot of work in this direction (functions like proto_is_dgram... addr_copy, etc ); you know my first approach was to thinks AF_UNIX as http/socks, but later I concluded that if we DONT require openvpn to specify destination to the proxy entity its not a proxy, its a (tunneled) pee; in the JAbber case , this could be an _already_ connected, _already_ configured destination JID not even known to openvpn, ... for openvpn its just another channel (socket). Indeed , AF_INET , AF_INET6 and AF_UNIX are mostly "siblings" from the connection pointo of view. > Then people > can add new drivers to their heart's content, while OpenVPN itself will > conveniently interact with a generalized abstraction of the model. Count on me for that ... hope I can resist the temptation 8))) Regards -- --Juanjo # Juan Jose Ciarlante (JuanJo) jjo ;at; mendoza.gov.ar # # GnuPG Public Key: gpg --keyserver wwwkeys.eu.pgp.net --recv-key 66727177 # # Key fingerprint: 0D2F 3E5D 8B5C 729E 0560 F453 A3F7 E249 6672 7177 #
