Freelancer Protocol, need help with some packages

utrack

Hey,

Right after user selects a character I receive a bunch of unknown packets. Anyone has a clue what they could mean, or where to look for info?

Here’s log dump.

Disregard that, I messed up the data flow; that should be the outgoing packets.
If anyone stumbles upon that thread: 52\54-02 packets are the player list enums and rank\sys\grp updates.

Another problem… Dunno what could cause it.

That’s what happens while switching rooms:

After that, client should send FLPACKET_CLIENT_REQUESTLOCATIONINFO roomid=otherroomid type=1, but it doesn’t. What could be the cause?

May I ask what you want to achieve? Are you modifying FLHook? Is this a normal behaviour of Freelancer?

utrack

Nah, I’m modifying FOS.
Well it looks like under certain circumstances (unknown) clean client does not ask for new room’s info when switching rooms in multiplayer.

Schmackbolzen

Are you still working on the server? To me it looked like you stopped completely. Would be nice if at least someone has the time for it

adoxa

Is it a deck? Decks are typically a single room, where it really just switches the view.

Someone should I’m totally rewriting it @ https://bitbucket.org/utrack/fos , akka branch. Old one is in default branch

No, just a usual base.
I found a problem - awful typo in dplay protocol’s ACK responses + i didn’t report player’s own group\rank\system - dunno which one fixed it but it works now.

utrack

Adoxa (or anyone :D), could you help me with package?

The full package is 1A-01-04-00-00-00-00-00-00-00, type is 0x1A01. It happens when we’re opening commodity dealer list - I’m assuming it’s some sort of asking for price\list from server, but I can’t find reference to it anywhere. Info about how to respond to it would be awesome.

P.S.: Win8.1 - impossible to launch vanilla FLServer

Schmackbolzen

That’s nice to hear!

I have windows 8.1 (updated last weekend) and FLServer + Freelancer work fine. You have to install the DirectPlay component, though (Windows asks at launch).

If by 0x1A01 you mean FLPACKET_COMMON_REQUEST_RANK_LEVEL then idk - it hasn’t show up in my testing (start Solo MP, create new character, go to commodity dealer, buy Boron, go back to Cityscape, back to dealer, sell Boron; nor is it present in the few dumps I’ve been sent).

Aha, thanks! Maybe that happened because i found that one while sniffing on Disco…
What’s the response for that? I got

04 00 00 00 FF FF FF FF
```, but the rank is 14…

Is there any doc i can get packets and responses from?

adoxa

PacketDump.cpp… This may help, too.
