Free socks software for linux

SS5 is a socks server that implements the SOCKS v4 and v5 protocol. As a proxy server, SS5 authenticates, profiles and processes network requests for clients.
Socks Server 5 establishes connections to application hosts for client applications. When the client attempts to access the network, the client connects to the SS5 daemon instead of the application host.
Following authentication, clients request that SS5 perform network activities for the client.
The activities might include:
CONNECT
BIND
UDP ASSOCIATE
The SS5 protocol is independent of application protocols, and can assist with different networking services, including telnet, ftp, finger, whois, gopher, and WWW access.
Enhancements:
- Fix code

tsocks provides transparent network access through a SOCKS version 4 or 5 proxy (usually on a firewall).

SOCKS servers are a form of proxy that are commonly used in firewalled LAN environments to allow access between networks, and often to the Internet. The problem is that most applications dont know how to gain access through SOCKS servers. This means that network based applications that dont understand SOCKS are very limited in networks they can reach. An example of this is simple telnet.

tsocks role is to allow these non SOCKS aware applications (e.g telnet, ssh, ftp etc) to use SOCKS without any modification. It does this by intercepting the calls that applications make to establish network connections and negotating them through a SOCKS server as necessary. If youre on a network firewalled from the internet with a SOCKS server for outside access, telnet cant use this server and thus cant telnet out to the Internet., sou you cannot get out.

tsocks is based on the shared library interceptor concept. Through use of the LD_PRELOAD environment variable or the /etc/ld.so.preload file tsocks is automatically loaded into the process space of every executed program. From there it overrides the normal connect() function by providing its own. Thus when an application calls connect() to establish a TCP connection it instead passes control to tsocks. tsocks determines if the connection needs to be made via a SOCKS server (by checking /etc/tsocks.conf) and negotiates the connection if so (through use of the real connect() function )

GNet is a network library. It is object-oriented, written in C, and built upon GLib. It is intended to be easy to use and port. It supports abstract Internet addresses, TCP, UDP, IP Multicast, IPv6, asynchronous DNS lookups, SHA, MD5, Base64, URIs, and SOCKS.
It comes with documentation and examples.
Main features:

CIPE is a Crypto IP Encapsulation.
This is an ongoing project to build encrypting IP routers. It works by tunneling IP packets in encrypted UDP packets. The protocol is designed to be lightweight and simple. Special care has been taken to make this work over dynamic addresses, NAT and SOCKS proxies.
Implementations are currently available for Linux and Windows.
Enhancements:
- This supports Linux 2.6 and the kernel crypto API.
