25     <h1>KGS Protocol Description</h1>
26    
27     <p>This XML document describes the KGS protocol. It is also used
28     to automatically generate the perl parser for all the messages and
29     structures in the protocol. Adapting it to other languages should be
30     trivial.</p>
31    
32 pcg 1.4 <p>If you feel you need to update the visual appearance of this
33     document, feel free to look at <tt>doc/doc2html.xsl</tt> and improve
34     it.</p>
35    
36 pcg 1.1 <h2>Structure and conventions of this document and the protocol</h2>
37    
38     <p>"Send" means messages send from the client to the server, while
39     "received" means messages send by the server to the client.</p>
40    
41 pcg 1.4 <p>Everything on the wire is in little-endian format (what a shame).</p>
42 pcg 1.1
43 pcg 1.4 <p>Primitive types are mostly integers (signed
44     "<code>I</code>&lt;bits&gt;", unsigned "<code>U</code>&lt;bits&gt;"),
45     ascii strings ("<code>username</code>"), or zero-terminated
46     UCS2-Strings ("<code>STRING</code>"). Yes, I know java is supposed to
47     do UTF-16, but no implementation seems to care...</p>
48 pcg 1.1
49     <p>For the rest, go figure or bug me, Marc Lehmann &lt;pcg@goof.com&gt;</p>
50    
51     <h2>Stream and message structure.</h2>
52    
53 pcg 1.4 <p>After connecting to the server, a handshake byte is sent. It's
54     the major version number of the protocol the client expects to
55     receive. Version 3 and 4 are mostly the same, except that Version 4
56     clients expect server messages to be compressed, version 3 clients
57     not.</p>
58    
59     <p>The server sends back his protocol number, which is always 3 in
60     the current protocol. Most of the protocol variation is determined by
61     the server using the client version that is used in the initial login
62     message, not the initial handshake byte.</p>
63 pcg 1.1
64     <p>After the initial handshake, the client sends uncompressed
65     messages, while the server sends back a zlib-compressed
66     stream (<a href="http://rfc1950.x42.com/">rfc1950</a> and <a
67     href="http://rfc1950.x42.com/">rfc1951</a>).</p>
68    
69     <p>All messages have the same header:</p>
70    
71 pcg 1.3 <struct name="message_header" send="yes" recv="yes">
72     <member name="_unknown" type="U16"/>
73     <member name="length" type="U16"/>
74 pcg 1.1 The length is the length of the full message including the header.
75 pcg 1.3 <member name="type" type="U16"/>
76 pcg 1.1 If the type is &gt;= 0x4000 this is a message for a specific channel. The channel
77 pcg 1.3 number is always the next U16.
78     </struct>
79

118 pcg 1.3 <h2>Structs used in send messages</h2>
119 pcg 1.1
120     <message type="0000" name="login" send="yes">
121 pcg 1.3 <member name="ver_major" type="U32" default="2"/>
122     <member name="ver_minor" type="U32" default="4"/>
123     <member name="ver_micro" type="U32" default="67"/>
124     <member name="name" type="username"/>
125     <member name="password " type="U64" default="0"/>
126     Password is a number calculated as follows (VERY insecure, basically plaintext!):
127 pcg 1.4 password = 0; for char in characters do password ← password * 1055 + ascii_code (char);
128 pcg 1.3 <member name="guest" type="flag" default="1"/>
129     <member name="_unknown3" type="U16" default="0"/>
130     <member name="locale" type="locale" default='"en_US"'/>
131     <member name="clientver" type="DATA" default='"1.4.1_01:Swing app:Sun Microsystems Inc."'/>
132 pcg 1.4 The "default" is the java vm version, not exactly he client version. However,
133     you should always send a tetx like "Jonathan's C client bersion 0.6" or somesuch,
134     so the server can, if necessary, block broken clients or client versions.
