I don't need anyone to tell me HOW if there is a way, i would like to find that out myself, but is there a way to receive rednet.send messages that your computer isnt ment to send? Like, if the ID 1 is sending to 2, can i use computer 3 in order to read that message via either networked modems or wireless?

Yes there is.

Attach a modem to the PC
Wrap it.
Open the channel corresponding tot he id of the receiving PC.
Listen for events and enjoy.

Rednet is just wrapped moddem calls.

Rednet is extremely insecure. Just see what you can do with a wrapped wireless modem…

So i already knew you could do this, i mainly wanted to see how many people would reply saying they did/with a way. Channels 65533-65535 contain ALL rednet traffic. 33 contains all, 35 is broadcast only, and 34 is gps signals. 33 doesnt catch GPS, but it catches send and broadcast. So if you ever want to sniff traffic, just look on 33 + 34.
