hi there,

Congratulations Luigi Auriemma .) i have been seeing your hard work and i must say it, that's really fantastic. thanks for sharing your knowledge is very helpfull.

ok, so i'm posting here one doubt before i do this project with vietcong 0.96 multiplayer demo game. is it possible to find all the ip's from the players on-line inside of Directplay 8? and it's possible to close those ip's connections if i'm using as a server (similar like a ban)? It will works like a tcp/ip manager: nick, ip, ban, unban, but using outside the game.

I haven't start yet that project but i think i must build one .dll to inject a code to the game for that or if not i will made a .exe that will looks like a PB application. any advice please?

thanks for for your attention,
greetings from,

Leand2o

interesting question, the viewing of the other players IP address is (by default and common sense) allowed only in peer2peer multiplayers which is sometimes used in DirectPlay games.

as far as I remember the vietcong's multiplayer is not p2p so no packets should be exchanged directly with other players and then it's udp based so there are no connections established to/from other clients.

obviously you can verify everything using a sniffer (for example http://www.wireshark.org) during the connection to a server and you should see only the packets to/from the server

I would like to suggest something else than wireshark. CommView, it is not free, but im sure you'll figure something out.
commview allows you to monitor specific process, so you dont have to figure out what packet is what..etc. or wpe pro, but often it gives lot of errrors on lot of applications.

if the problem is just monitoring a specific process, proxocket is perfect for the job too.
then commview is commercial (blah) and exist also some free alternatives other than wireshark like smartsniff

i'm using vista OS for that kind of search i use Essential Net Tools. ok i have tried today and yap, UDP protocol. only thing i can get from the game now is the name of the players when they join the game and left the game with artmoney focus in vietcong guid. other thing its possible is that i can close udp connections sending one big packet of data to the server. for e.g. if 30 players are in the game and i send that packet, in the same time, 10 players lose the connection from the server.
