I have doggedly referenced back to the resources section on this site to figure out how to make an async server. Richard Hallett's article is exactly what I need: an async socket server for console. (!Windows). As much as I try to change things, I have a consistant problem. It would seem that select(...); always thinks there is a client wanting to connect. Here's my code: CCybServer g_Server[10]; int main() { int i=0; int nfds=0; //compatibility (dunno) fd_set conn; //setup read variable for select int stored=0; //where data stored int Clients=1; //clients connected (i mean that to be a 1) //Make all my mini-servers while(i<10) { g_Server[i].Init(); g_Server[i].CreateSocket(5000); g_Server[i].Listen(); g_Server[i].m_iID=i; i++; } while(1) { i=0; while(i<Clients) { stored=0; //i have to reset this to 0 because this isn't in //a seperate function at the moment //All this for select... g_Server[i].timeout.tv_sec=0; //what makes it non-blocking g_Server[i].timeout.tv_usec=0; // FD_ZERO(&conn); //set conn to nothing FD_SET(g_Server[i].m_CybSocket, &conn); //if i !do this, no one //connects //get data from server/listening socket nfds=g_Server[i].m_CybSocket+1; //compatibility (?) stored = select(nfds, &conn, NULL, NULL, &g_Server[i].timeout); //anything trying to get in? //If it's a logic error on my part: //here's where it would occur... if(stored>0) //meaning select got something { if(g_Server[i].m_bUsed==false) //m_bUsed means it's been connect { Clients++; g_Server[i].Accept(); //standard accept code g_Server[i].m_bUsed=true; //therefore that "server" in use } } //Standard send and receive, just bouncing info //back in this case... g_Server[i].Receive(); g_Server[i].Send(g_Server[i].m_szReceive); i++; } } } I realize it's rough, but if you can decipher my abhorent tabbing and give me a hint I'd appreciate it. It'd be preferable not to change code as much as possible (I know that's terrible server design, but I have matchingly terrible client design and that'd prolly just lead to more questions that i could figure out for myself otherwise Thanks again.

Hey guys it worked! Thanks a lot for your help. You save me a lot of headache.

I'm still not sure how to direct connecting clients to the right socket, or how to properly re-open socks when they disconnect, but I'll reference more tutorials for that.
