When I trying to log onto battle.net, I am successful connecting to the server. I then proceed to send the protocol byte and the 0x50 packet.

After that I'm waiting for any packet from bnet, but none ever comes. I'm lost as to what to try next in assessing the situation.

Any ideas or suggestions?

The ethereal log of my bot is here if it helps:

Looking at the debug output of my program, it seems to be only getting recv's of 0 bytes. :-\

www.filebox.vt.edu/users/rluu/stuff/ethereal_log_4_13_04b[/quote]A more useful log would be one which is stored in hex.

And preferrably, even contains messages to show the differences between receiving data and sending data (for example "sending data 'xyz' ... receiving data 'abc'").

Yes, for example:

Ok. My apologies.

33899 Is the port I binded to and port 6112 is bnet.

Right click on one of the packet titles and click "Follow TCP Stream". It gets rid of that extra gibberish, so that all you see is from "ff 50" on. It made things a lot easier for me.

At the bottom, under filters, type this:

tcp.flags.push == 1

and hit enter. That'll get rid of empty packets. Do that, then repost, if you don't mind :)

The stuff before 0xFF... isn't that big of a deal since the offset into the packet is always the same.

I have a log here with a whole lot of data sent in packets without push set.

hmm, that's always worked for me. Is there a better way to filter packets without data? I don't even know what push IS, but it seems to work :)

<edit> too cool, me and Adron posted in the same second!

I'd like to point out that battle.net is disconnecting you at this point...

eww, you have the gamecode wrong.

SXEP != SEXP

gogo fix! :)

Well, I tend to just use "follow tcp stream". The first file he posted loaded fine in Ethereal, and was easy to look at. The second file he posted had the right data easily locatable since he'd pointed out the right packet:

edit: Ah, good job iago, I was just about to go dig up bnetdocs and take the packet apart, but then you posted the probably correct answer :)

Ahh, thank you so much Iago & everyone else for looking at this. ;D

I was going crazy trying to figure it out.

I had all the other TCP sends with Len = 0 there because I thought that maybe one of those were causing it.


It works now. :)
