If the selected METHOD is X''''FF'''', none of the methods listed by the
client are acceptable, and the client MUST close the connection.
The values currently defined for METHOD are:
o X''''00'''' NO AUTHENTICATION REQUIRED ---------无用户密码 00
o X''''01'''' GSSAPI ---------??? GSSAPI ?
o X''''02'''' USERNAME/PASSWORD ---------有用户密码 02
o X''''03'''' to X''''7F'''' IANA ASSIGNED
o X''''80'''' to X''''FE'''' RESERVED FOR PRIVATE METHODS
o X''''FF'''' NO ACCEPTABLE METHODS ---------失败 255
The client and server then enter a method-specific sub-negotiation.
换言之,就是向服务器发送三个字节的Byte数组,由于是无须用户/密码校验,展开来写是 05 01 00
然后服务器返回两个字节的信息,第一个字节固定,第而个字节是说明,如果是16进制的FF(即十进制255)表示连接失败(o X''''FF'''' NO ACCEPTABLE METHODS)根据上面的列表,我们连接成功应该第二字节为 00.
然后我们进入第二步,请看以下RFC说明:
Once the method-dependent subnegotiation has completed, the client
sends the request details. If the negotiated method includes
encapsulation for purposes of integrity checking and/or
confidentiality, these requests MUST be encapsulated in the method-
dependent encapsulation.
The SOCKS request is formed as follows:
+----+-----+-------+------+----------+----------+
|VER | CMD | RSV | ATYP | DST.ADDR | DST.PORT |
+----+-----+-------+------+----------+----------+
| 1 | 1 | X''''00'''' | 1 | Variable | 2 |
