This paper presents the Socks package, an Internet socket service consisting of client library routines and a daemon which interact through a simple protocol to provide convenient and secure network connectivity through a firewall host. Client software applications can be easily modified to utilize the Socks library routines in place of the normal socket library calls such that all outgoing connections will go through the Socks daemon (sockd) running on the firewall host. We will review several methods for setting up secure environments and then explain the detailed mechanisms of the Socks package. A current implementation will also be briefly discussed along with experiences with it. 1.0 Introduction Security is a major consideration when connecting a network to the Internet. One of the more important issues which must be addressed is intruders attempting to gain access to local hosts. A common method for preventing these types of intrusions is to install a "firewall", a single point...
