This is simple realization of socks5 proxy server according to the RFC 1928 using boost::asio library. The server uses async socket calls for data forwarding and io_service for message processing. Currently, boost_socks5 proxy server works only in NO AUTHENTICATION REQUIRED mode.
The proxy server build was tested with boost version 1.58. However, earlier versions of boost will probably work as well.
To build on Linux install Boost library and run the following command:
g++ -Wall -std=c++11 boost_socks5.cpp -o boost_socks5 -lboost_system -lboost_thread -lpthread
Run the following command:
g++ -Wall -std=c++11 -I <Path_to_Boost_Include> boost_socks5.cpp -o boost_socks5 -static -L <Path_to_Boost_Libs> -lboost_system -lboost_thread -lwsock32 -lws2_32
Ignore Boost std::auto_ptr warnings if any.
Run ‘Developer Command Prompt for VS2015’ and use the following command:
cl /EHsc /MD /I <Path_to_Boost_Include> /Feboost_socks5.exe boost_socks5.cpp /link /LIBPATH:<Path_to_Boost_Libs>
Currently, configuration file contains the following settings:
- port – which the server listens for incoming client connections
- buffer_size – size of data transferring buffers. Do not make this value too small because it will greatly increase the number of read/write calls when forwarding huge amount of data
- verbose - verbosity level (0 – errors only, 1 - connect/disconnect, 2 - traffic packets size)
