  1. It's funny that the code above outputs actually a packed GUID (without any compaction for zero bytes, thus the bitmask is 0xFF). So it's ok when filling a packed GUID field in a packet.
  2. I do not check top of the header (it can be done using the sources), but should note that a packed GUID has variative length. In your post, the whole structure uint8 packedGUIDMask # for example, 0xFF uint64 packedGUID is termed as "packed GUID". It contains a number of bytes (1 to 8) for uint64. The number is equal to the number of non-zero bits in the bitmask packedGUIDMask, thus the length of the filed is well defined.
  3. You could find the method converting 64-bit (GUID) data to a packed GUID here. BTW, 1.12 client does not use this, which was/is a usual compatibility issue while backporting handlers to it. A brief explanation. A GUID is 8-byte long; consider is as a byte array A where A[0] is the lowest GUID byte, ..., A[7] is the highest one. Create a side byte (the bitmask) this way: if A[i] is nonzero then i-th bit is 1, else the bit is 0. Then we can omit zero-valued elements of A from transfer (a packet), and transfer the bitmask following non-zero elements of A only. In the worst case (like items on a long-living realm) we get the 0xFF bitmask and will transfer 9 bytes instead of 8 (non-packed GUID). However in the best case (player GUID under 256), we get bitmask 0x01 and transfer only 2 bytes instead of 8. A packed GUID emerges by the protocol in packets that may contain a player GUID, saving bandwidth for several (zero-valued) bytes.
  4. AFAIK the only difference between these two is the size. The compressed update may contain (and does, actually) updates for several objects at once. IIRC the compression is made simply by gzipping the packet data. Unsure if usual update SMSG_UPDATE_OBJECT may contain several updates at once, but perhaps it may as well. However I'm certain that these packets are fully interchangeable, i.e. equivalent. A compressed update becomes critical when you get an event-reach world around your character. It may be raiding a boss, a BG, just a capital with 200+ players so on. The updates are "broadcasted", i.e. sent to every player participant, and network bandwidth fades quickly.
  5. I apologize for the wrong opcode referencing. The following is correct for 3.3.5a (12340 build) client: SMSG_UPDATE_ACCOUNT_DATA_COMPLETE = 0x0463, while for older ones, perhaps including 8606 build, the older SMSG_UPDATE_ACCOUNT_DATA = 0x20C must be valid. To avoid such confusions, you better create the needed dumps for the proper version yourselves. Run a Mangos server wih set up WorldLogFile parameter in the mangosd.conf. The log file will contain the communication sequence with symbolic opcodes and unparsed other packet data. If you use the TC for that, you set up PacketLogFile in its worldserver.conf and get a binary file. You could parse it into a nice text form with the WowPacketParser utility. The utlity is capable to parse older data as well, for 2.4.3, in case you manage to get the binary packet log. An example sequence of actions at CMSG_PLAYER_LOGIN (i.e. at login by the chosen character) was presented here, once again for 12340 client. I could have misinformed you on the packet sequence as well, since had been referencing WotLK 12340 client. It looks like the login protocol was changed between 8606 and 12340 builds. Taking a 8606 packet log, I see SMSG_ACCOUNT_DATA_TIMES within the large responce sequence on CMSG_PLAYER_LOGIN. Also I see two CMSG_UPDATE_ACCOUNT_DATA without any server responce. So, analyse your own logs please. Good luck!
  6. Check your content of the `realmlist` table in the `realmd` DB. The `realmlist`.`address` string field is used to tell the non-local clients on what host to look for the mangosd server (aka realm server). It might be either a full DNS hostname resolvable at your friends computers, or an IP (specifically, IPv4?) address accessible to them. It looks like your table contains the string 555.555.555.555 here, which is not satisfactory.
  7. You need rather to send the confirmation that the server have handled the update successfully. This is a short responce packet. For 1.12 client, it would be probably the opcode SMSG_UPDATE_ACCOUNT_DATA = 0x20C, while for 2.4.3 it is SMSG_UPDATE_ACCOUNT_DATA_COMPLETE = 0x0463, Just remember this is a dialog, a query - a responce. On the TBC (2.4.3) client, the next packets represent another dialog phrase: CMSG_READY_FOR_ACCOUNT_DATA_TIMES SMSG_ACCOUNT_DATA_TIMES with the only difference that here CMSG is a short query and SMSG is a longer responce.
  8. Blizz have planned to teach a character some spells ingame. They have created the "Learn" counterparts for those spells. The Learn spells have spelleffect SPELL_EFFECT_LEARN_SPELL=36 and the spell id to learn in EffectTriggerSpell; they provide also the well known animation. It is why your spellids did not match. The learning process looks like casting a "learn" spell upon the character. You could find required spells with the SpellWork, for example (note that it needs access to the extracted DBC files, specifically, to the Spell.dbc).
  9. If you find somewhere a protocol description, let us know as soon as possible Until then, all that everyone had were sniffes. Today, sniffing the traffic between a server emulator and the client is the simplest way. There is a lot of sh*t set up at a player login. Below is a part of sniff for the WotLK client logging in a character.
  10. Not being an expert on handling the packet at this level, I would still advise do not take a risk with this operation: dec %= 0x100 The modulo op in Python is quite a thing. Use bitwise operation instead: dec &= 0xFF Unsure if it helps, but it is the only difference from the referenced Java code I've managed to spot.
  11. The in-game space is realized as a set of maps. You're transferred from a map to another one via teleport (so called far teleport). It could be an instance entrance or ship/zeppelin teleportation. The maps are numbered sequentially (with some holes), this number is known as the mapID. The map list is kept in the client file Map.dbc, you could find some description of its content (3.3.5a client) here. A map can have a very large size (meaning, room), like the whole continent, Kalimdor (id 1) or Eastern Kingdoms (id 0) or Outland (id 530). Clearly, a more tight net is needed for many game mechanic implementations. An example of such mechanics is a spell enabled only in a part of the map. Such a smaller grain is called a zone, and further smaller one is an area. The data on these are presented in the client file AreaTable.dbc, described somehow here. However, a position on the map is defined by the mapID and coordinates X, Y, Z only. It means that the zoneID and areaID are subordinate, being actually calculated by the core from the position data. The smallest grain is called a cell and is implemented in the core by the similarly named class. The SMSG_CHAR_ENUM packet contains lots of information about the characters present on a given account. It allows the client to display "Select a character" screen since you've logged in. A necessarily large size of the packet made it the popular tool for DoS attack to the server. This was serious enough to budge the TC team to implement a rudimentary protection from this attack type.
  12. Sorry, too used to the TrinityCore structures. Yes, it's ok. The access level is controlled by `account`.`gmlevel` here, that has a reasonable default value (0 = user). Just try to reset the fileds mentioned above with an update like this (for MyUsername example player): UPDATE `account` SET `v`=NULL,`s`=NULL WHERE `username`='MyUsername';
  13. When you manually change (rather than create anew) user credentials, namely username and sha_pass_hash, then reset also v and s fields to an empty srting (NULL is disallowed there in the TC, though Mangos allows it). You might wish also to fill some other fields in the account table entry, for example, email, joindate, and expansion. Also, when you register a new user, you should define his/her permissions as well in the account_access table. IIRC no more information is needed to allow the user login.

    WoW path

    It looks like path=patch, meaning the major client version. While the best developed one is TrinityCore 3.3.5a (WotLK), I cannot recommend it since they have used to break it substantially from time to time. Of Mangos here, Zero should be the most developed one, though it does not mean the blizzlike grade.
  15. If I remember correctly, none of the Mangos sources were adapted to the OpenSSL 2.0. If so, you need to stay at OpenSSL 1.1 which is not the default one for new system distributions. Check your OpenSSL version and try to downgrade it to 1.1 (which will rather be impossible), or try to install it along with 2.0.
  16. Ensure you've cloned the repository with the --recursive parameter, see red note here (that example is for Zero server).
  17. As far as I know the config and the core, there is no such feature. You may rate the damage and HP of the whole creature class (normal, elite so on) over the whole world. It won't be a coding challenge to apply this scheme map-specifically. Though I doubt that such an extended scheme will be nicely controllable from the config file. I believe you can apply the new rates even without restarting the core. Just change the rates in the config file and use "reload config" command.
  18. There is no single option for this because it would require an extensive testing to set a new balance properly (and, what a balance? 10 and 20 are quite different player numbers). However, using `Rate.Creature` settings in the CREATURE AND GAMEOBJECT SETTINGS section, you can customize the mobs easily. None timers will be affected, thus you need also to reduce bosses HP getting a chance against the timed boss enrage. Most other phase switching events in the scripts are controlled not by fixed timers but instead by % of the boss HP.
  19. While knowing nothing on how the EasyBuild works, I would not recommend to use the latest mysql version anyway. Try the proper build (32 or 64 bit) of the later 5.x version instead.
  20. I cannot propose any of the "tools", but if I could do that, I rather won't. The only consistent way to delete an account with all related information provides the core itself via GM command `account delete`. Similarly, the DB dump related to a core contains the `realmd`.`realmlist` settings for a realm supported by this particular core. It stands for a reason. For example, the core may or may not support specific client build (`realmbuilds` field), and no third-party utility can be aware of such important details.
  21. Does your LAN box have a route to your server? You could check that by `ping`. Does your `realmlist.wtf` file on the LAN box point to 192.168.0.11? I've never believed in the Win firewall interface. To be sure, you could turn the firewall off for a short time (perhaps while the Internet connection is down), on the both boxes. If you have `telnet` command available, you could connect from the LAN box to the auth port of the running server: `telnet 192.168.0.11 3724` Any answer will mean the LAN box wow client issue.
  22. The server uses the data provided within the client intensively. The minimum necessary ones are maps and DBC files. The DBC files contains variety of information, for example, spell descriptions, model descriptions so on. All these data are to be extracted for the server from the client MPQ archives. For this reason, the data extraction step requires the client. The MPQ archives are used by the extractors built from the respective projects, and some extractors (including these) check also the wow.exe version.
  23. Briefly: turning an instantiable map (like BG or dungeon one) into a usual map is impossible. A fully consistent way to do that would be related to a client files editing followed by DBC reextraction. However you could try to clear "instantiable" attribute from the corresponding map while loading Map.dbc. It might work but not should since the client will understand the map as instantiable one still. Enabling the sole map instance for an instantiable map is a more consistent and technically even simpler way, but it requires hacky changes to the core too.
  24. The original error is about missing Microsoft C runtime libraries in the system you run the extractor. You use an undescribed repack, so we cannot guess what exactly version of the Visual C++ Redistributable (like this one) you need to install. Try some versions, maybe starting from the one referred to. Another way would be getting required DLLs one-by-one, like this recovery of the missing DLL. But there might several DLL be missing. The MaNGOSExtractor_detailed.txt file above contains the log of mmaps extraction. It must be the last step of extraction, starting at maps and vmaps already present.
  25. set realmlist 100.14.93.118 This is the realmlist.wtf content. I've just connected with the client 2.4.3 build 8606 to the realm mentioned above by the "player" account and made the character with the same nick. (Be sure either removing unneeded accounts from `realmd`.`account`, or at least set `gmlevel` to 0 for those; the respective commands: account delete, account set gmlevel). The issue is elsewhere outside your server settings.
