Process of authorization on a login-server and call on a game-server Authorization on a login a server occurs in some stages. 1) a login the server sends us a greeting in the form of a package in length of 11 bytes (in general it contains the information on the version). 2) we answer it RequestAuthLogin with inquiry 3) if the password true, sends us a package with 32 bit number of our account (it always constant) - we shall call SessionKey *1. 4) we send it RequestServerList, on what the server answers us the list of servers containing game, ports, number of playing users, the maximal number of users. 5) we send RequestServerLogin, on what the server checks ours AccessLevel (if it is equal-1, means we banned) and depending on our login, the password, a level of access and a socket, generates unique 32-bit SessionKey *2 on which in a consequence we will be authorized with a game-server. If the game server in down, simulates this condition (administrators do it for work on a server) or is simply full, refuses to accept us. 6) if all is good, we climb on a game server. We send it a certain package (for everyone C3 a server it the, but constant), on what it answers 12 byte with a package containing first 4 bytes of key which it is fastened to others 4 bytes (which are constant) and is received 64 a bit key. In the further we shall use it for decoding and coding game packages. It is important to note, that with everyone of races coded a package, its length increases to the first part of a key. 7) we send it a login and two identifiers (already in the ciphered kind) which we have received in a session with a login-server. In the answer we receive the list of characters. Here so, in 7 stages we shall be authorized on a server =) Difficultly, but it is safe. Probably, someone from you had a question: and whether probably to come on a game server directly? Without participation a login of a server. About it I shall write below. 2. Enciphering packets As I already wrote enciphering of packages above, for enciphering game packages lineage uses a 64-bit key. The first it 4 byte undertake from the very first package of the game-server, the second. N-th symbol from a clear text, XOR's with N-th byte a key further undertakes. In parallel with it XOR's (N-1)-th symbol from a clear text on 0xFF. Above results of both calculations operation " digit-by-digit And " is spent. And on such algorithm each symbol since the first is ciphered. As you can see, as each subsequent symbol will be ciphered, depends from previous. And it means, that if at us the first part of a package is for whatever reasons damaged, or it simply is not present, decipher the second part we cannot. Well it so, to a word. Actually it for us is not important. Still it is important to note that the first part of a key variable. With each new deciphered package, to the first I 4 byte the length of these to data increases. That is, having an initial key (at the moment of connection with a login a server) and, having pulled out a package during the certain moment from a session with a game-server decipher it we cannot. For this purpose we need to restore all packages which were up to it. Basically, quantity of possible combinations of a key of equally ~423 million. In view of simplicity of algorithm, modern computers can make somewhere 10 000 iterations in a second (can even more) and to find a key a maximum for 12 hours. But for this purpose we need to know even about the maintenance of a package. For what authors have made a key to variables? I think, all it is clear, with a view of safety. Though, it is a question about TCP (instead of about UDP as in the same halflife) in which someone stranger "to put" in a session extremely inconveniently. 4.Protocol. As well as in packages of the login-server, first two byte are allocated towards the length. Further the byte means type of a package. Here on types of packages which the client lineage2 (should process C3 the some people I shall make comments): // sends a login-server 0x01 loginfail2 0x02 accountKicked1 0x03 loginok 0x04 serverlist

Yes, really, all process of game looks approximately so: the server constantly transfers us a condition of the world, position of Mobs/players/npc and others. We when something should (be gone, attacked and other) transfer "inquiry". All is very simple. 4. XID and ObjectID each thing (the subject, NPC) in game has the 16/32 bit the identifier (trades - 8 bit). Its sense that, you see, it is more convenient to transfer on a network 2/4 byte number, than a phrase of N length like: " Crystal Scroll: Enchant Weapon (Grade B) " or nickname NPC like " Magister EzEraL ". As you understand, it serves for identification of this or that object. The list of these identifiers and NPC/subjects corresponding them to be stored and on a server and the client, and among themselves they is not synchronized in any way. That is, if to replace this table on a server it is necessary and the client is one of the reasons, why at each server the patch. Besides this identifier is still 32 bit Object ID. After call in the game world, a server appropriates to each of subjects which are at the Persian, unique OID. And OID each subsequent subject is OID current-1. That is OID it is generated at all random, and under the order. After assignment, OID it is reserved, so that anybody has not managed any more to receive similar. This information, by the way, is not confirmed by source codes, that is is my own conclusion. If it not so, on proprocession of a full circle (from 0xFFFFFFFF up to 0x00000000) it can it will turn out so, that already borrowed OID it will be appropriated to a new belonging, that will lead to unknown consequences (to an opportunity of cloning or simple falling of a server). But a problem that range OID enough big:) And if to be more exact, it is necessary to appropriate OID to ~4.3 billion things to pass a full circle, what even on a server with mega-online will borrow N of days (and can also weeks). Still time I shall repeat, this all the assumption. But the matter is that I, for example, Did not see some la2 server (even off) with uptime more than week. The problem just in it can? And as a whole, OID it is necessary for struggle against cloning. To be exact with revealing of this. As to NPC, OID at them stands out under the same law, but at occurrence NPC in the world. With OID characters the same. 5. Examples of packages. a) purchase of subjects to put on buying up a subject, we need to take advantage with 3 of packages. The first 0x94 (SetPrivateBuyMsg). Apparently from the name it establishes that message which will be is deduced above a head at the Persian during the moment of trade (what on a yellow background). Here an example: // SetPrivateStoreBuyMsg a package XX XX // the Size of data 94 // type of a package 41 00 41 00 41 00 42 00 42 00 42 00 // the text. Symbols should be divided among themselves null-byte 00 00 // the end of a package Further we use a package of type 0x91 (SetPrivateBuyList). In it just we transfer quantity of subjects, Item ID and the price. For example: // SetPrivateStoreList a package XX XX // the Size of data 91 // type of a package 01 00 00 00 // quantity of things // the beginning of the block e1 02 00 00 // Item ID 00 00 01 00 00 00 // how many subjects of the given type to buy up e8 03 00 00 // the price // the end of the block I shall a little explain this package. We have put them on buying up 1 thing with IID 0x2e1 (Scroll of Resurrection) for 1000 аден. And last package of type 0x1d. As to sale, there practically all same. Only instead of ' SetPrivateBuyMsg ' used ' SetPrivateStoreMsg ', and instead of ' SetPrivateBuyList ' - ' SetPrivateStoreList ' accordingly. And, nearly has not forgotten, instead of Item ID used Object ID because we sell any concrete subject. b) private messages Here all is very simple. XX XX // the size of data 38 // type of a package (Say2) 42 00 42 00 42 00 42 // the message (BBBB) 00 00 00 02 00 00 00 // breakspace=) 41 00 41 00 41 00 41 // nickname (АААА) 00 00 00 // the end c) an example of a package in which the server transfers us the list of all subjects which are on чаре. And, this package assigns to everyone Item ID unique Object ID. XX XX // length of a package 1b // type of a package (0x1b on antaras.ru) 00 00 05 00 // quantity of subjects 04 00 // type of a belonging 1e 26 14 40 // Object ID d4 15 00 00 // Item ID (0x15d4 - Tutorial Guide) 01 00 00 00 // Quantity 05 00 00 00 00 00 00 00 00 00 00 00 00 00 // Enchanting, quest item, droped or not and still something 01 00 // type of a belonging 1d 26 14 40 // Object ID 7b 04 00 00 // Item ID (0x47b - Squire's pants) 01 00 00 00 // Quantity 01 00 00 00 00 00 00 08 00 00 00 00 00 00 01 00 // type of a belonging 1c 26 14 40 // Object ID 7a 04 00 00 // Item ID (0x47a - Squire's Shirt) 01 00 00 00 // Quantity 01 00 00 00 00 00 00 04 00 00 00 00 00 00 00 00 // type of a belonging 1b 26 14 40 // Object ID 0a 00 00 00 // Item ID (0x0a - dagger) 01 00 00 00 // Quantity 00 00 00 00 00 00 80 00 00 00 00 00 00 00 00 00 // type of a belonging 1a 26 14 40 // Object ID 42 09 00 00 // Item ID (0x942 - Guild Member's Club) 01 00 00 00 // Quantity 00 00 00 00 00 00 80 00 00 00 00 00 00 00 d) we speak with NPC on an example of learning skills For the beginning, we need to allocate NPC and to get with it dialogue: 04 // type of a package (Action) 51 14 10 48 // OID NPC // further there are coordinates the character c6 51 01 00 // X 52 45 02 00 // Y b8 f2 ff ff // Z 00 // the end 21 // type of a package (RequestBypassToServer) 6c 00 65 00 61 00 72 00 6e 00 5f 00 73 00 6b 00 69 00 6c 00 6c 00 00 // learn_skill 00 // the end Thas from now

Login-server. Introduction. We shall begin that developers lineage2 have separated a login a server from game more less to unload and without that the hammered channel of a game server. Besides the login a server has property to hang (and, it has begun with с3 versions lineage and proceeds to this day) and to not start up users on a server. But those who already play, do not test absolutely any discomfort =) And owing to out all of the same gays which could find and distinctly explain to developers where all the bug has crept in, it remains till now not fixed. And so, not looking at all charm of idea with unloading the game channel, our domestic administrators persistently mould a login a server on one machine together with game. Enciphering of packages For enciphering packages which the login-server exchanges with the client, lineage uses blowfish. Yes, that algorithm which has been developed by Bruce Shnejerom in 1993. About blowfish it is important to know, that it is the symmetric block code. Symmetric - means, that the algorithm uses 1 confidential key by which data encrypt/decrypt will be decoded. And if to speak particularly about blowfish on the basis of this key are generated 18 32-bit keys and 4 matrixes in the size of 256 32-bit words everyone. By which data, in turn, encrypt.will be decoded. The block code - means, that blowfish processes given by blocks (on 8 bytes). And still it means, that if integrity has been broken, we in a any way can restore a part. With reference to lineage, it is necessary to tell, that a key on the basis of which are generated connect, is a constant and it is precisely registered in source codes l2j (here on what 99 % of researchers lineage which assumed were strewed, that the key should be transferred in one of packages - see references in the end). Still it is important to note that the first 2 byte data of a package are not ciphered. With enciphering, I think, we have understood. We go further. 2. Structure of packages(login). First two byte a package (what are not ciphered) contain length of data of a package (as well as in halflife). The following byte bears in itself the information on type of a package. The login-server processes packages: 0x00 - RequestAuthLogin (the inquiry about authorization - contains a login and the password) 0x02 - RequestServerLogin (inquiry about call about a server) 0x05 - RequestServerList (inquiry about the list of servers) On the others it simply does not answer, leaving only record in broad gullies. The client processes packages of following types: 0x01 - authorization has not passed 0x03 - you are successfully authorized 0x04 - the answer on RequestServerLogin 0x06 - the answer on RequestServerList The designer of packages on С(example. With structure of packages we have understood, now it is possible to realize in programm everything, that was manual above.

man here is l2off section not l2j lol man

First do you see one to compile the pack?no just use the compile version.Second do you see one to sumbit a bug?No Second many teams take the code and add them in their pack without credits.And so i will let leaching and steal codes from me?

I update the file swich more retail but the whole project is not for public anymore

La2-World is not availbale for the public.We add 1005 OF INTERLUDE skills and we dont share them

Iparxoun ellines hackers alla i perisoteroi eine e3oteriko kai douleuoun

Saki we discuss for serius server low rate or major pvpm arena reborn is new and has nothing special and yes it it is very good but not as echo or a off server

I modify the ddl source of l2walker to work one every server even if server admin add a protection tool and ect.ALso i add some new things about enchant weapons and ect but i need the source to update connection packet Does anyone have it?

Its not mental faction but l2jfree but mental share the db.Our projrct is not avallable for te public since i commit 100% interlude skills only for my friend because i didnt see many ppl support me to register just download and leaching.So the lack ppl download my gve pack now is not available

The best is www.la2-crazy.com official server.It has x1,x4,x7,x320 official interlude server.No lag,no bugs,no exploits no bots no nothing.Best server And see the players online.There are in x4 4526 at this time nad no lag many ppl and more...

Any bugs report

Download eclipse.Download l2jsource code add in experience.java the lvl you want and compile with ant.There are plaenty guides

First this db that solution share is official l2jfree(not faction) Well just create 4 sqls and some nw tables and enamble system.Try my gve version in my svn for interlude.For c5 download l2jfree c5 and do it

i share the system see first post

new version added

yes

What to datapack?Just mane some htmls and sqls that my pack already have them.Then enable faction for source or use my pack that already have it

Thx man now i will commit many db fixes and wedding system fix so the server will take less ram than usual the same for cpu and it will be more retail.In 1 hour i will copile and share the pack for those that dont now how to compile
