<section>
- <title>Handshake</title>
- <p>
- The handshake is discussed in detail in the internal documentation for
- the kernel (Erlang) application.
- </p>
+ <title>Distribution Handshake</title>
+ <p>
+ This section describes the distribution handshake protocol
+ introduced in the OTP-R6 release of Erlang/OTP. This
+ description was previously located in
+ <c>$ERL_TOP/lib/kernel/internal_doc/distribution_handshake.txt</c>,
+ and has more or less been copied and "formatted" here. It has been
+ more or less unchanged since the year 1999, but the handshake
+ should not have changed much since then either.
+ </p>
+ <section>
+ <title>General</title>
+ <p>
+ The TCP/IP distribution uses a handshake which expects a
+ connection based protocol, i.e. the protocol does not include
+ any authentication after the handshake procedure.
+ </p>
+ <p>
+ This is not entirely safe, as it is vulnerable against takeover
+ attacks, but it is a tradeoff between fair safety and performance.
+ </p>
+ <p>
+ The cookies are never sent in cleartext and the handshake procedure
+ expects the client (called A) to be the first one to prove that it can
+ generate a sufficient digest. The digest is generated with the
+ MD5 message digest algorithm and the challenges are expected to be very
+ random numbers.
+ </p>
+ </section>
+ <section>
+ <title>Definitions</title>
+ <p>
+ A challenge is a 32 bit integer number in big endian order. Below the function
+ <c>gen_challenge()</c> returns a random 32 bit integer used as a challenge.
+ </p>
+ <p>
+ A digest is a (16 bytes) MD5 hash of the Challenge (as text) concatenated
+ with the cookie (as text). Below, the function <c>gen_digest(Challenge, Cookie)</c>
+ generates a digest as described above.
+ </p>
+ <p>
+ An out_cookie is the cookie used in outgoing communication to a certain node,
+ so that A's out_cookie for B should correspond with B's in_cookie for A and
+ the other way around. A's out_cookie for B and A's in_cookie for B need <em>NOT</em>
+ be the same. Below the function <c>out_cookie(Node)</c> returns the current
+ node's out_cookie for <c>Node</c>.
+ </p>
+ <p>
+ An in_cookie is the cookie expected to be used by another node when
+ communicating with us, so that A's in_cookie for B corresponds with B's
+ out_cookie for A. Below the function <c>in_cookie(Node)</c> returns the current
+ node's <c>in_cookie</c> for <c>Node</c>.
+ </p>
+ <p>
+ The cookies are text strings that can be viewed as passwords.
+ </p>
+ <p>
+ Every message in the handshake starts with a 16 bit big endian integer
+ which contains the length of the message (not counting the two initial bytes).
+ In erlang this corresponds to the <c>gen_tcp</c> option <c>{packet, 2}</c>. Note that after
+ the handshake, the distribution switches to 4 byte packet headers.
+ </p>
+
+ </section>
+ <section>
+ <title>The Handshake in Detail</title>
+ <p>
+ Imagine two nodes, node A, which initiates the handshake and node B, which
+ accepts the connection.
+ </p>
+ <taglist>
+ <tag>1) connect/accept</tag>
+ <item><p>A connects to B via TCP/IP and B accepts the connection.</p></item>
+ <tag>2) send_name/receive_name</tag>
+ <item><p>A sends an initial identification to B. B receives the message.
+ The message looks like this (every "square" being one byte and the packet
+ header removed):
+ </p>
+<pre>
++---+--------+--------+-----+-----+-----+-----+-----+-----+-...-+-----+
+|'n'|Version0|Version1|Flag0|Flag1|Flag2|Flag3|Name0|Name1| ... |NameN|
++---+--------+--------+-----+-----+-----+-----+-----+-----+-... +-----+
+</pre>
+ <p>
+ The 'n' is just a message tag.
+ Version0 and Version1 is the distribution version selected by node A,
+ based on information from EPMD. (16 bit big endian)
+ Flag0 ... Flag3 are capability flags, the capabilities defined in
+ <c>$ERL_TOP/lib/kernel/include/dist.hrl</c>.
+ (32 bit big endian)
+ Name0 ... NameN is the full nodename of A, as a string of bytes (the
+ packet length denotes how long it is).
+ </p></item>
+ <tag>3) recv_status/send_status</tag>
+ <item><p>B sends a status message to A, which indicates
+ if the connection is allowed. The following status codes are defined:</p>
+ <taglist>
+ <tag><c>ok</c></tag>
+ <item>The handshake will continue.</item>
+ <tag><c>ok_simultaneous</c></tag>
+ <item>The handshake will continue, but A is informed that B
+ has another ongoing connection attempt that will be
+ shut down (simultaneous connect where A's name is
+ greater than B's name, compared literally).</item>
+ <tag><c>nok</c></tag>
+ <item>The handshake will not continue, as B already has an ongoing handshake
+ which it itself has initiated. (simultaneous connect where B's name is
+ greater than A's).</item>
+ <tag><c>not_allowed</c></tag>
+ <item>The connection is disallowed for some (unspecified) security
+ reason.</item>
+ <tag><c>alive</c></tag>
+ <item>A connection to the node is already active, which either means
+ that node A is confused or that the TCP connection breakdown
+ of a previous node with this name has not yet reached node B.
+ See 3B below.</item>
+ </taglist>
+ <p>This is the format of the status message:</p>
+<pre>
++---+-------+-------+-...-+-------+
+|'s'|Status0|Status1| ... |StatusN|
++---+-------+-------+-...-+-------+
+</pre>
+ <p>
+ 's' is the message tag Status0 ... StatusN is the status as a string (not terminated)
+ </p>
+ </item>
