get ip fra client socket
hejsahar et lille problem.
jeg har laver en dummy af en tilnet server.
som en gang i fremtiden skal kunne modtage fiktive mail's og kunne kontroler om det er spam.
men lige nu sider jeg fast med et forholdsvis simpel problem.
jeg skal have ip på de cliente der connecter.
pt. har jeg lave 2 classe, CServer,CClient
CServer tage sig af serveren, oprettelse af server, lytter til port, opretter threat.
CCleint, tager sig af at modtage og sende data til client.
hvordan får jeg fat i ip på clienten der connecter??
