socks5 server c

SOCKS V5 server

一個簡易的SOCKS V5 代理伺服器。

Features

• 支援TCP 代理和UDP 代理
• 支援代理DNS 查詢
• 支援使用者名稱密碼認證方式

Build

使用make完成編譯和連結。

$ make

若跟上CFLAG=-DDEBUG則開啟調試模式：

$ make CFLAG=-DDEBUG

Usage

不含任何選項啟動，則監聽1080 端口，無需認證。

$ ./server
NO AUTHENTICATION REQUIRED
Listening at 0.0.0.0:1080

帶上-h選項則顯示幫助資訊。

$ ./server -h
usage: ./server [options]
options: 
  -a < address >         Local Address to bind (default: 0.0.0.0).
  -p < port >            Port number to bind (default: 1080).
  -u < path/to/passwd >  The path to passwd.
  -d                   Run as a daemon.
  -h                   Show this help message.

選項-a和-p分別用來指定伺服器綁定的IP 位址和連接埠號碼。

$ ./server -a 127.0.0.1 -p 8080
NO AUTHENTICATION REQUIRED
Listening at 127.0.0.1:8080

選項-u用於開啟使用者名稱密碼認證方式，選項後面必須跟上一個檔案的路徑。該檔案的每一行對應一個用戶，用戶名和密碼之間用逗號,隔開，例如：

$ cat ./passwd
user1,123456
user2,666
user3,2333
$ ./server -u ./passwd
USERNAME/PASSWORD
3 users
Listening at 0.0.0.0:1080

若帶上-d參數，伺服器將脫離終端，成為守護程式。

$ ./server -d
NO AUTHENTICATION REQUIRED
Listening at 0.0.0.0:1080
PID is [xxxxx]
$ netstat -ntlp | grep xxxxx
tcp        0      0 0.0.0.0:1080                0.0.0.0: *                   LISTEN      xxxxx/./server
