Hi all, i am working on UDP hole punching to allow communication between two computers hidden behind their respective NATs (Home Router).
I have been able to achieve the same using netcat and hping3 , as described here: http://www.cyberciti.biz/tips/howto-linux-iptables-bypass-firewall-restriction.html <http://www.cyberciti.biz/tips/howto-linux-iptables-bypass-firewall-restriction.html>in short: 1. Register a SYN flag with the receiving router using hping.(punch a hole in the NAT) 2. start listening for udp packets at the receiving computer. 3. send a udp packet from the sender to the receiver. Now i try to do the same thing using python and sockets, step 1: holepunch , send UDP packet from receiver to sender from socket import * s = socket(AF_INET,SOCK_DGRAM) host = "<receiver ip>" port = <receiver port> s.bind((host,port)) s.sendto("Message",("<sender ip>",<sender port>)) here i get the following error *error: [Errno 22] Invalid argument* i dunno how to resolve this issue. Also can someone plese help me out with the holepunching. Am i doing something wrong ? -- regards ------- Kunal Ghosh Dept of Computer Sc. & Engineering.
