Hi

I been playing with tcp conections to get my msgs from msn from the tcp packets.. as far as snifing them and using them in what I want goes I did fine. Now on a second stage I'm trying to have my program send myself packets but I can't seem to achieve that.

How should one do to comunicate with the same port that msn uses to RECEIVE my msgs?

Thanks

edit: Going through the packets lead me nowhere. Changed my aproach to hooking directx dlls and it's looking good right now. Managed to send a msg to the game now I need to learn how to retrieve msgs from MSN Live. If anyone was interested

The port you see on your end in netstat is just an endpoint of a TCP connection.  Injecting packets into the stream of an established TCP connection without dropping it is very difficult and not a practical way to approach this.

It would be much easier to program a proxy, if you have an actual need to do this.

Thanks for replying. I've been searching about this for a week and you're the first to actually say something.

I'll see what I can find about programming a proxy.

Do you mind if I PM you with my findings or any further questions I might have in the way?

Thanks a lot.

Socket hooks are not practical, as adeptus said. Proxies do not work for everyone and often mess things up if done incorrectly...but they're your best bet.

Ok maybe if I tell you guys what I'm trying to do it'll be easier for you guys to tell me what's the intelligent aproach.

I've got this full screen game that I play through the internet. My problem is that I need to alt-tab so I can reply to msn.

I've found that sniffing my own packets I can send msgs to people from inside the game. If I just say something like "test@test.com: hey buddy" inside the game and catch the string in the outgoing packet I could isolate the msg with RegExp and whatnot and send it to the person I wanted to through msn plus script. Now the reverse is turning out to be quite difficult. The server (or the other player) sends messages in the same fashion but I couldn't send a packet to the port of the game.

I could only see two ways of doing this: 1 - messing with the incoming packets (first guess was just sendin my own packets to the port and now through a proxy) 2 - messing with the screen and directx so I could have a box or alert with the messages.

I thought going through the packets would be easier but maybe I'm wrong.

What do you guys think?

If you don't mind, please add me on msn so I can pick your brains
