Starting Work on SoF Opcodes/Structs

SEQ isn't converting network to host byte order on the raw soe opcodes but here:

Code:

Dec 31 2008 05:43:05:342 [Raw] [Client->Server] [Size: 12]
[OPCode: 0x0100]
000 | 00 00 00 02 6b 0b ee 8f 00 00 02 00              | ....k.......

int crc length 0x00000002 = 2
int session id 0x6b0bee8f
max packet size 0x00000200 = 512

Code:

Combined packet

contains:

Code:

Dec 31 2008 05:43:05:722 [Decoded] [Client->Server] [Size: 4] - 
[OPCode: 0x3594]
000 | 00 00 00 00                                      | .... 

Dec 31 2008 05:43:05:722 [Decoded] [Client->Server] [Size: 68] - OP_ZoneEntry
[OPCode: 0x5a6b]
[Name: OP_ZoneEntry][Updated: 10/07/08][Type: ClientZoneEntryStruct (68) ==]

The first packet isn't a soe ack you can tell by the opcode and the fact that it doesn't include a sequence number. Likely some kind of I am ready for this info packet.

Code:

Dec 31 2008 05:43:05:882 [Raw] [Server->Client] [Size: 5]
[OPCode: 0x1500]
000 | a5 00 01 4a 4f                                   | ...JO

This is an ack packet, tho it looks wrong, they're usually 4 bytes total including the opcode 2 without this one is 7 byte with the opcode 5 without. The opcode is SOE_ACK tho.

Code:

Dec 31 2008 05:43:05:882 [Raw] [Server->Client] [Size: 406] - Varies in size
[OPCode: 0x0900]
000 | 00 00 00 19 0e f0 1a c1 88 00 00 00 00 00 00 64  | ...............d

These are standalone packets, encoded and compressed with a 2 byte sequence on the top probably 0x0000 since this is the first and a crc on the end. It's also possible to combine packets within an 0x0009 packet but you can't combine a raw packet and an eq packet inside the 0x0009 they both have to be EQ packets.

Code:

Dec 31 2008 05:43:06:696 [Raw] [Server->Client] [Size: 507] - 
[OPCode: 0x0d00]
000 | 00 26 00 00 5b c2 22 60 fd 19 df 72 00 00 00 00  | .&..[."`...r....

This is a fragmented packet like 0x0009 they are encoded and compressed they have a sequence number for recombining and a length byte. These are used when the data chunk being sent is larger than the max frame size sent on init: 512.

I know this doesn't help at all for figuring out what you need for the SoF stuff but maybe if you understand how the raw protocol works you'll understand it a bit better.
