SOCKS Proxy
Pro Server Only


SOCKS Overview
The Sambar Server SOCKS proxy functionality relays data between a client and an application server. From the application server's perspective, the SOCKS proxy is the client. This "circuit-level" firewall hides the true identity of the clients from the application server and provides a single point of access for external traffic.

SOCKS is a networking proxy protocol that enables hosts on one side of SOCKS server to gain full access to hosts on the other side of the SOCKS server without requiring direct IP reachability. SOCKS redirects connection requests from hosts on opposite sides of a SOCKS server. The SOCKS server authenticates and authorizes the requests, establishes a proxy connection, and relays data.

The Sambar Server SOCKS proxy supports both version 4 and version 5 of the SOCKS protocol, however, authentication from SOCKS5 is not supported in the current implementation. See www.socks.nec.com for more information.
