A highly-customizable lightweight SOCKS5-server supporting RADIUS, Redis, subnet whitelisting and blacklisting, session counting.

For SOCKS5 protocol specification, consult https://www.ietf.org/rfc/rfc1928.txt.
For details on username/password SOCKS5 authentication, consult https://tools.ietf.org/html/rfc1929.

This version of VPE supports username/password authentication (METHOD 02) and no authentication (METHOD 01).
It supports CONNECT and UDP ASSOCIATE (fragmentation is not implemented) requests.

To run VPE, specify the -conf=<full path to the config> flag. /etc/VeeProxyEngine.conf is assumed to be the default config location.

VPE listens for SIGUSR1 signals and displays data about idle workers and the connection queue on SIGUSR1.

Use the -h flag to see the configuration details.
Use the -v flag to see the version of your build.

We advise that you set this up as a system service.
If you are willing to use RADIUS for authentication, we highly recommend running Redis for caching.
No matter what authentication scheme you choose, it makes sense to run Redis to keep track of your users' sessions.

For the detailed documentation and a configuration example, see VeeProxyEngine.conf.
