BNLS_VERSIONCHECKEX2

[Chriso]

When should this be sent? I keep getting Invalid version response from S=>C SID_AUTH_CHECK
I am currently sending it after I receive SID_AUTH_INFO response

[Ersan]

whenever you want...

[l2k-Shadow]

you can send any BNLS packet anytime.

[Ersan]

is there an echo in here?

[l2k-Shadow]

I posted a more detailed description of what you posted.

I assume your parsing out ur 0x1A responce correctly, but also use the exeinfo provided in 0x1A , you cant have it like "DDA-TRiCk`BoT" or watever , bnet now checks that

When does bnls send back the exe information?

Code Select Expand

(BOOL) Success*
(DWORD) Version.
(DWORD) Checksum.
(STRING) Version check stat string.
(DWORD) Cookie.
(DWORD) The latest version code for this product.

Do any of those mean exe information, I'm stumped here.

well let's see, exe info is a string, and there is only one string in there.

Actually, thats what I was going to edit my post w/, but I didn't know if I was even looking at the right packet for the info. Why don't they match bnetdocs; for example in 0x51 it says EXE Info, shouldn't it in the BNLS packet?

@School so typing fast btw.

[Chriso]

Oh maybe it's the ULONGLONG? I just assumed that was FILETIME? does it have a different format/size? how many bytes should it be in length?

Code Select Expand


0x1A

(DWORD) Product ID.*
(DWORD) Flags.**
(DWORD) Cookie.
(ULONGLONG) Timestamp for version check archive.
(STRING) Version check archive filename.
(STRING) Checksum formula.




Heres what I'm getting from BNLS compared to hashing

It's the timestamp of the MPQ file so that the client would know if the mpq was updated in case it has an outdated file in it's cache.

Is that the same as the 'FILETIME' of the MPQ received in 0x50?

yes it's the FILETIME, however, it looks like you're parsing the data wrong, considering you have some crap in front of the Game.exe, maybe if you pasted your parsing code for parsing 0x50 and sending/receiving 0x1A..?

Okay heres 0x50
