Hi, I need help regarding the raw sockets in wireless (802.11 or wifi) networking. I want to send a packet using raw socket (on data-link-layer or layer 2) from STAtion to AP (Access Point). Just for info: I am using madwifi as wifi-driver on ubuntu 8.04. So, I want to send packet of ath0 of one device to ath0 of other device. Of course using raw sockets.... I searched on the net extensively (believe me, i am doing it rigourously from last 5...

need to connect to computer over tcp/ip i have the external ip but without port forwarding I can't connect to the server . Is there any way to configure the server to accepts connection on the external ip and port define by the server without configuring the router ? (how does emule, FogCreek CoPilot, LogMeIn does it ? or other peer to peer application )

Hi all, I am new to C and I need some help solving an issue with network programming. So in general, i have two programs running: Program A and Program B. Description of A: Send out packet with SN = i (SN is the label for the packet. i.e first pkt SN=1, 2nd pkt SN=2 etc) Set timer If RN=x is received from B, and x=i+1, set SN=i+1. (RN is label for packet coming back from B) Otherwise, ignore. If timer expires, resend pkt SN=i Reset timer and...

Thanks....

You're using an uninitialized pointer in each case of recv. Just pass the actual address of your structure and cast it to char * for the recv call: Code: struct Data { char data1[255]; char data2[255]; int val1; }; struct Data dt int ch=recv(new_socket,(char *)&dt,sizeof(struct Data),0); printf("The Elements of structure "); printf("Book- %s Author- %s Code- %d",dt.data1,dt.data2,dt.val1); and:...

Hello! SUMMARY: I'd like to create such a system: [1] Skype on mobile phone -> [2] Skype on server -> [3] plugin to Skype (3rd party application) -> [4] speech recognition Sphinx4. Normally Skype outputs speech to the speaker, normal behaviour of Sphinx4 is to receive speech from microphone. I need to change it so that Skype would redirect its output sound to TCP socket and Sphinx4 would receive it from this TCP...

I have this problem. Have an application ( Warcraft III ) that uses udp broadcasts for lan management , usually when you run the application two times and join the LAN with one you can't join with the other because bind fails, so I hooked bind and used the SO_REUSEADDR option and that worked I was able to join LAN with both clients, now when I create a game broadcast packets are sent from both clients to retrieve games, notify for game...
