no.

should be 5 bytes long, 6 with the leading 0x00

Any reason why I get all this stuff AFTER I receive the correct response?

You are connecting to a zone connect to the SSC billing server. All that extra 'junk' is what is used to verify that you are connected to the real SSC billing server, and is used to keep your password secure even from the server and/or proxies.

In other words, just ignore it.

I also get stuff after other packets like:

00 04 00 00 00 00 80 17 ec 26

is that also just stuff I should ignore?

How come asss test zone doesn't have the extra stuff yet has no password warning when logging in?

There's no warning because its on SSC

How do you tell whether it is on SSC or not?

How can the client get on a chat channel before it has even logged in?

Ack packets should be exactly 6 bytes long. There should never be anything after them unless they are encapsulated in a cluster packet. If you see a packet starting with 00 04 that is longer than 6 bytes, you are doing something wrong.

Mr. Ekted, yea im pretty sure its my encryption, here is my decrypt():

Code: Show/Hide

sub ssdecrypt {
my @packet = @_;
my ($tempKey, $tempInt, $count, @output, $index);

if (@packet[0] == 0x00) {
$index = 2;
} else {
$index = 1;
}

$tempKey = $serverKey;
#$count = int( scalar(@packet) + (4 - scalar(@packet) % 4) );
$count = scalar(@packet);
#$count = scalar(@packet[$index .. $#packet]);

@output = @packet[$index .. $#packet];
for ($i = 0; $i < $count; $i += 4) {
$tempInt = dece_int(@table[$i .. $i+3]) ^ $tempKey ^ dece_int(@output[$i .. ($i+3)]);
$tempKey = dece_int(@output[$i .. ($i+3)]);
@output[$i .. ($i+3)] = ence_int(int($tempInt & 0xffffffff));
}

unshift(@output, @packet[0 .. $index-1]);
return @output;
}

See how there are 2 commented $count's, well it depends on which one I have to how many extra packets add on, if I make it the last one (.................... NEVER MIND I just found out how to do it while posting! I got it write now, no extra stuff

What language is that?

It looks messed up enough to be PERL. Maybe that's why your encryption doesn't work... you're mixing languages!

Its only perl, so is the rest of my core, who said I was doing it in C

Yea well were both making a bot core, both have questions about the same things.
