XML dumb here .. i got .18 up on one box

but the beta box at home ill be trying to figure out what yah said there :)

i know the file ... but know what to do with it is a bit diffrent.

Ill look it over some when i get home, maybe it will click.

thanks for the fast work.

I lied about the packets just being shifted. Things are alittle messier than that.

The spawnstruct packet (opcode 0x0208) is bigger and re-arranged a bit, so cleaning it out will be a big help.

some other opcodes:

0x0144 - OP_ZoneChange
0x006c - OP_PlayerProfile
0x022b - OP_ZoneEntry
x00172 - OP_ZoneSpawns

I hate aligning packets, so I'm gonna go play and let someone else figure it out.

Almost done at work... I have my version of the source all ready to go, and will start dumping packets as soon as I'm home. I imagine some endurance info has been added.

Below is a mostly working spawnStruct, I'm sure some of the locations are wrong but it generates skittles.

Still havent figured out the changes to playerSpawnPosStruct because that appears to have changed along with manaDecrementStruct.


struct spawnStruct
{
/*000*/ uint8_t NPC; // 0=player,1=npc,2=pc corpse,3=npc corpse,a
/*001*/ char unknown001[42];

/*049*/ int32_t race; // race

What am I missing here, are these opcodes that are traditionally ignored? If I could identify which structures were where, I'm sure I could puzzle out the allignment easily enough, figure out what padding is needed, etc..

What am I missing here, are these opcodes that are traditionally ignored? If I could identify which structures were where, I'm sure I could puzzle out the allignment easily enough, figure out what padding is needed, etc..

You really want to be looking at the zone and world data logs which contain the uncompressed/decrypted/split data and not the all data log which contains the raw compressed/encrypted/combined data.

Enjoy,

Ya...there are 3 tasks when they do an update (putting asside an actual change in encryption)

1: identify "implicit length" packets
2: assign opcodes to packets
3: correct packet structures.


Task 1 was nicely automated (God bless you, Fester)

Task 2 is a group effort on the part of the community. you have to associate events in the game with the packets they generate. So someone sits in an empty zone and drops 13 pods of water and then looks in the log for 13 packets with the same opcode. chances are that is the opcode for a drop. Everyone has different strategy for workin it out, but people post the ones they find. Eventually Zaphod comes across and munges it all down for us (yay!)

Task 3 is when you line up items in a packet with their actual meaning (Sure its the player packet, but which byte holds your level, etc)

--piggy

[codepig666]

bleh. had to decouple this one from what had formerly been shared structure elements.

opcode is 0x0028 if anyone hadn't figured that out yet.

/*

Hey Code,

Could you help me out here, i am not all here tonight, could you idiot proof walk me through what i need to do.

I am running 5.0.0.2

Thanks in advance from tonights idiot :(

[Cryonic]

the spawn and player structs are in everquest.h

What used to go into decode.cpp is now held by the xml config file zoneopcodes.xml.

Because the everquest.h file is being changed, this will require a recompile of SEQ.

[PhoenixZorn]

can someone hop on over to the macroquest IRC room and tell us all when the CVS update is done? =)

[Talorn]

I was told that there will be another patch tonight so I stopped working on locating opcodes and such. I'll pick back up tomorrow after the patch.

[perlmonkey]

Zaphod thanks, I did not realize the all packet log was pre-decryption. That explains the migrain I was getting ;-)

Code, yeah I understand the process, I was trying to lend a hand in stage 2, because I need to get my bazaar stuff working again (and my guess is that I'm the only one who will be looking at / caring about the bazaar search structures from my patch).

[perlmonkey]

The servers are still locked, and I have to go to work. I really wish they could get these patches right on the first try. Don't they realize the seq people are trying to work, here?! And how come Absor never posted on OUR board? Geez, "community" my shiny metallic orb! ;-)

[Talorn]

OP_ItemPlayerPacket 0x0281
OP_SpawnDoor 0x0282
OP_MoveDoor 0x0129
OP_ShopRequest 0x00f9
OP_Save 0x00f8
OP_ItemPacket 0x02d0
OP_TargetMouse 0x0175
OP_GroundSpawn 0x00fc



I could be wrong on these but i've spent a few hours playing around with them as i hate to post bad info ~

[Zaphod]

Well, so far it looks like this mornings patch didn't change any of the implicitlen stuff or other opcodes. So opcode collection can continue where it left off...

Enjoy,
Zaphod (dohpaZ)

[perlmonkey]

0x0063 and 0040 are the most common unknown packets I'm getting, so I'm going to assume they are some kind of player position updates (testing in bazaar).

[perlmonkey]

[dumb post deleted by me, since my opcodes were decimal (%04u) not hex (%04x)... doh -perlmonkey]

ok, very new to this, but I think my method is sound at finding the opcodes, but not sure how to verify. I'm monitoring my zone.log and comparing it to zoneopcodes.xml.

0x0175 OP_TargetMouse
0x00fc OP_GroundSpawn
0x0014 OP_Consent
0x00bf OP_CastSpell
0x0020 OP_ItemLinkClick
0x01f7 OP_ItemPLayerPacket
0x008d OP_SetRunMode
0x025e OP_GuildMemberUpdate
0x0025 OP_CommonMessage

As I indicated, this is my first time trying to help with opcodes, so use lube if you must rape me. Definitely needs verification from an experienced person.

Adding more here as I find them (let me know if you'd rather have a new post):
0x0208 OP_NewSpawn
0x0294 OP_LoadSpellSet
0x0057 OP_WhoAllRequest

First off, I want to appologize for any confusion, since the above "hex" numbers are actually decimal ;-)

I've finished patching now to the point that I have moving skittles for myself and mobs, and also my bazaar searches are working again. Attached are just the changes that were posted above, plus the new opcodes I've found.

[perlmonkey]

Doh! I missed your 3 updates, I'll go add those in to the mix.... damn browser, not doing what I want heh.

[perlmonkey]

Ok, combining my findings, and everything that I have seen in this thread, I get the attached patch (note: this also contains the bazaar search code and datastructures, it would be cool if that could be added to the code base so that my bazaar patch was just the logging, and not the data changes).

[jeff221]

I was pretty damn proud of myself when I did a clean install of RedHat and got SEQ fired up on the first attempt, now the patch arrives and f'd it all up a few months later.

My question is simple, where can I find a few links to how one goes about changing these op codes, how to cleanly recompile and get back up and running?

Some links and information to where you geniuses find these opcodes would be nice too. Feed my brain, I'm hungry!

~Jeff


p.s. Oh yeah, also.. what the hell do I do with a *.diff file?!?

[perlmonkey]

I'm still seeing some broken opcodes after applying the above patch, but we're getting very close. These are the codes I've seen in the last few minutes:

Unknown opcode 0x01c5 len=8
Unknown opcode 0x01c5 len=8
Unknown opcode 0x01c5 len=8
Unknown opcode 0x01e7 len=8
Unknown opcode 0x01e7 len=8
Unknown opcode 0x01c5 len=8
Unknown opcode 0x0208 len=267
Unknown opcode 0x01c5 len=8
Unknown opcode 0x01c5 len=8
Unknown opcode 0x0208 len=267
Unknown opcode 0x0208 len=267
Unknown opcode 0x01c5 len=8

Jeff, I'm sorry but those of us working on getting seq working again are kind of busy. Any intro to Unix tools should discuss the use of patch to apply diffs, and grep is a great tool for finding what file something is in. As for how we (and I say 'we' loosly, since I'm an outsider here) find opcodes and such, it's all guesswork based on the data we have available to us: network packets, patch messages from SOE (which might hint at what changed), the EQ files (which contain many things, of course).

[perlmonkey]

About 0x0208.... the data for those packets always has two names in it, and 208 is not far from 1f0, so my guess is that 0x208 is actually TraderShop. Anyone think that sounds wrong?

[perlmonkey]

We just got a serverwide ad for the new server, so I can happily report that 0x01da is the op for serverwide message, and the data, which is 200 bytes long has a leading data header of 12 bytes followed by the text, which is null-padded at the end.

Heh, finally a broadcast ad was good for something.

[Teh_Ish]

Anyone get this working with SEQ5? I've put in all the numbers but my position isn't working, and I'm still getting massive spam in my console

I updated the structs, as well.

Specific problems are..

OP_ClientUpdate (0x28) (dataLen: 30) doesn't match: sizeof(playerSelfPosStruct):36

and

Warning: error on zone-client: size > left (size=76, left=23, opcode=0x003f)

Codepig: Are you sure on that selfPosStruct? That's 36 total, should only be 30 from the data I"m getting..

Mind being a bit more specific? I'm getting hit with "size > left" spam constantly, and I can't figure out why. I've put in all the changes, and it's not working. Hence I'm here, asking for help. Simple, no?

I'd say ShowEQ 5 is about 2-4 opcodes from being committed to CVS...

Enjoy,
Zaphod (dohpaZ)

[perlmonkey]

I don't know where my head is today... duh. 0x0208 is NewSpawn, which btw makes things much more usable... see attached, up-to-date patch that has a few changes from the last one, and is the last I'll do until I make some struct progress.

I'll post the needed Bazaar patch to the relevant thread later.

[makeitworknow]

Ok, I downloaded a fresh CVS of .18 and applied the second .diff patch. Using RH 8.0, was not able to get SEQ working, and had a couple of questions.

I saw that under the SEQ beta 5 that it said SEQ must be compiled with QT 3.1. Is that only for the 5 beta or is that also for the .18 version also? Currently using QT 3.0.5 to compile the .18 version.

Can anyone verify that a fresh CVS of .18 plus the second .diff patch listed here works?

I am able to ping my EQ box from my SEQ box. Got no errors during compile process, however it appeared that SEQ was not recognizing or picking up the traffic. Tried logging in and out, zoning, and no joy...no maps, no skittles, no nada. No errors in the logs that I can find....SEQ appears to start up normally but still not picking up the data. I've got the IP address of the EQ box in the Network config, and verified correct. I'm using the same equipment network wise that I was using before the patch and SEQ ran fine then. In the process of recompiling from scratch again to make sure everything went ok, but I wanted to make sure I wasn't jacking up something obvious here.


And DOH new patch!

Never mind. Second shot at it with the new patch worked like a champ.

P.S. Maybe you could pop onto the IRC and we can talk about what you are seeing.

[Hobo]

Did a little searching since it's been a long time since I've done any kind of patch to my SEQ. Can someone confirm that this is the proper way to apply Perlmonkey's patch?

1) Save the patch file to /seq

2) cd seq

3) patch < seq2003121904.diff

3) rm *.o

4) cd ..

5) make

6) make install


Or do I need a ./configure before I make and make install?


Thanks,

Hobo

[perlmonkey]

You should not HAVE to remove any object files OR configure, but it will not hurt. make should Do The Right Thing.

[Hobo]

Thanks much for the quick reply. Once it again I am a living example that the SEARCH feature works! =P

[Zaphod]

Just an FYI, I believe I've got all the necessary opcodes and structure changes for ShowEQ and will be doing a new release of ShowEQ 5 in the next couple hours.

I'll probably get around to 4.3.x sometime tommorrow as long as noone pisses me off. Certain individuals have been pushing my patience in the Help forums with their whining. So, we'll see.

Enjoy,
Zaphod (dohpaZ)

[ieatacid]

I'm just happy I got it working again by reverting back to the pre-beta build. Thanks again for the great work guys!


Anxiously awaiting the working beta version,

[Hobo]

Zaph, not to suck up or anything but most of us truly appreciate the efforts you and the rest of the "brains" around here put into SEQ.


Thanks.



Now a comment. Ran the patch or Perlmonkey's and it sort of works for me. When I zone the map loads properly for a few seconds and then just about the time the spawns come up the map shrinks to a tiny, tiny little size. I can zoom in x32 and it's still smaller than normal. Spawns are shown off the map with long strange white lines spewing out from them. SEQ then crashes with a seg fault.

Looking back through the data I can see multiple error messages like this:

WARNING: Op_ClientUpdate (0028) (dataLen: XXX != sizeof(playerSpawnPosStruct):18 or sizeof(playerSpawnSelfStruct) :30)

Note the "XXX" in the above warning is a number that varies from message to message.


I also see an error message that says:

error on zone-client: size > left (size=57, left=52, opcode=0x0028)


I don't know if any of this info is of help to you guys or not, but thought I'd post it anyway.


I should note that this is using the non-beta version 4.xx.xx

Zaphod, Please try to ignore those that tend to piss you off. We want you to know that we CERTAINLY DO APPRECIATE all the HARD WORK you put into this Project.... I wish I could contribute more, but I do not posses the Skillz to do it.....

Thanks again and Have a GREAT HOLIDAY !!!!!

[BlueAdept]

Hey Zaphod, dont let anyone get on your nerves. I almost left the boards because of a poster. I had even put up a poll asking if I should leave.

Ive relegated myself to the fact that there are some idiots that visit here from time to time. Eventually they get bored when they are done stirring up trouble and leave. Dont let it get to you. 99.9% of the people here really respect you and your work.

If you let things get to you on here, you will end up like this guy.

This is the 1st time I have had to patch as I am a new SEQ user. Here is what I did but it still doesn't seem to be working. Please tell me if I did something wrong.

1) I put the latest patch in the /showeq/src folder
2) I patched the files via "patch < seq2003121904.diff"
3) cd ..
4) make
5) make install

I had no errors at any point but when I run showeq it does not display the map or any information. Did I miss a step?

[perlmonkey]

I am getting some map resizing artifacts too... I'll see if I can track it down. No promises.

[uRit1u2CBBA=]

use patch -p0 < {file} and don't forget to do a new make -f Makefile.dist && ./configure

[Frank25]

When i apply the latest diff with patch it gives me a lot of
"Hunk #XX FAILED at XXX"
and tells me the rejects were saved to file.rej.

Does this mean the patch failed? or is this normal?
I dont hve to much experience with patching files by hand )

[Sneaky]

I applied the patch and recomplied but still no display and I segfault. Guess I will wait for teh real fix...thanks for trying

[perlmonkey]

It looks like CVS has been updated, so you should probably ignore this patch now....

[lildr00d]

Not sure if the opcodes are wrong or SEQ just intercepting then bad. SEQ works Im getting skittles and updates. I don't see any ''unknown'' on the map so unsure if thats related


Im seeing alot of:

unknown [server->client] [side 76] [opcode 0x025e]
*Guildmember name* -----------trash
*Guildmember name* -----------more trash
-----------even more trash

025e is listed as Guildmember update and that seems fitting since I get this message when one of them zones in and out.

getting same message when I loot my corpse seems opcode is right cause its saying 0x0141


Breakdown of opcodes giveing unknown so far. Hard to see as they scroll by so fast

262
25e -size 75
12a -size 2
141 -size 16
1a9
16a -size 8


sorry I dont have more data. Just started writeing all this down on a raid.. ;-)
