`Introduction
`
`Welcome to the AutoSOCKS! v2.1 secure Windows client for 16- and 32-bit Windows
`applications. AutoSOCKS v2.1 is the first commercial application to incorporate the SOCKS
`v5 security protocol standard, simplifying SOCKS deployment for end users and network
`managers.
`AutoSOCKS transparently intercepts WinSock communication requests issued by TCP/IP
`applications and processes them based upon a set of routing directives (rules) assigned when
`AutoSOCKS is configured. (For more information about WinSock, TCP/IP, and general
`network communications, see “Getting Started.”)
`On larger networks, AutoSOCKS can address multiple SOCKS v5 servers based on end
`destination and type of service. This feature enables network administrators to effectively
`monitor and direct network traffic.
`Features of AutoSOCKS v2.1:
`Supports both SOCKS v4 and SOCKS v5 standards
`•
`Supports RFC1928 and RFC1929 SOCKS v5 standards
`•
`• Network-based setup provides a single configuration point with a simple user interface
`• Transparently route connections from Windows applications to external networks through
`any SOCKS-based firewall system
`• Logging utility to troubleshoot problems with network connections
`• Enables internal network connections to pass through without interference
`• Enables network redirection through multiple SOCKS servers
`Supports multiple authentication methods including SOCKS v4 Identification,
`•
`username/password, CHAP, and SSL 3.0. Other authentication modules can be added
`Supports 16-bit WinSock 1.1 applications under Windows 3.1 and Windows for
`Workgroups 3.11
`Supports both 16- and 32-bit applications under Windows 95, Windows NT 3.51, and
`Windows NT 4.0

`appreciated.
`
`Getting Started
`If you're new to AutoSOCKS technology, the following section will help you understand what
`AutoSOCKS is and does, as well as its relationship to network security in general.
`
`Network Security in a Nutshell
`Escalating threats of computer viruses and increased potential for unwelcome hackers are
`forcing companies to seek ways to safeguard their corporate networks and the information they
`exchange. The first response to these concerns has been the development of security
`firewalls—software barriers that control the flow of information. But firewalls can’t easily be
`configured to handle complex security issues such as monitoring network usage, providing
`private communication over public networks, and enabling remote users to gain secure access
`to internal network resources.
`Enter SOCKS v5, an Internet Engineering Task Force (IETF)-approved security protocol
`targeted at securely traversing corporate firewalls. It was originally developed in 1990, and is
`now maintained by NEC. SOCKS acts as a circuit-level proxy mechanism that manages the
`flow and security of data traffic to and from your local area network or intranet. A workstation
`whose traffic is proxied by SOCKS is considered “socksified.” SOCKS is more than a
`standard security firewall. It also features:
`
`Petitioner RPX Corporation - Ex. 1021, p.9
`
`
`
`• Client Authentication: (SOCKS v5 only) Authentication allows network managers to
`provide selected access to internal and external areas of a network.
`• Traffic Encryption: (SOCKS v5 only) Encryption ensures that network traffic is private
`and secure.
`• UDP Support: (SOCKS v5 only) User Datagram Protocol (UDP) has traditionally been
`difficult to proxy with the exception of SOCKS v5.
`• Cross-Platform Support: Unlike most UNIX security solutions, SOCKS code can easily
`be ported to platforms such as Windows NT, Windows 95, and Macintosh systems.
`
`What is AutoSOCKS?
`AutoSOCKS automates the “socksification” of client applications, making it simple for
`workstations to take advantage of the SOCKS v5 protocol. When you run AutoSOCKS on
`your system, it automatically routes appropriate network traffic from a WinSock application to
`the SOCKS server. (WinSock is a Windows component that connects a Windows PC to the
`Internet using Transmission Control Protocol/Internet Protocol—TCP/IP.) The SOCKS server
`then sends the traffic to the Internet or the external network. Your network administrator
`defines sets of rules by which this traffic is to be routed.
`AutoSOCKS is designed to run transparently on each workstation. In most cases, you’ll
`interact with AutoSOCKS only when it prompts you to enter authentication information for a
`connection to a secure SOCKS server. You may also occasionally need to start and exit
`AutoSOCKS, although network administrators often configure it to run automatically at
`startup.
`To understand AutoSOCKS, you first need to understand a few basics of TCP/IP
`communications.
`
`TCP/IP Communications
`Windows TCP/IP networking applications such as e-mail or ftp use WinSock to gain access to
`the network or the Internet. WinSock (Windows Sockets) is the core component of TCP/IP
`under Windows. (TCP/IP is a suite of protocols that the Internet uses to provide for services
`such as e-mail, ftp, and telnet.)
`
`WinSock Connection to A Remote Host
`Via WinSock, an application goes through the following steps to connect to a remote host on
`the Internet or corporate intranet:
`1. The application executes a Domain Name System (DNS) lookup to convert the hostname
`into an Internet Protocol (IP) address. If the application already knows the IP address, this
`step is skipped.
`2. The application requests a connection to the specified remote host. This causes the
`underlying stack to begin the TCP handshake. (The TCP handshake is the process by
`which two computers initiate communication with each other.) When the handshake is
`
`6 • AutoSOCKS v2.1 Administration and User’s Guide
`
`Petitioner RPX Corporation - Ex. 1021, p.10
`
`
`
`complete, the application is notified that the connection is established, and that data may
`now be transmitted and received.
`3. The application sends and receives data.
`
`What Does AutoSOCKS Do?
`AutoSOCKS slips in between the Windows TCP/IP application and the single access point—
`WinSock. In simple terms, AutoSOCKS redirects WinSock calls (both parameters and data)
`and reroutes them through a SOCKS-based server when required. The routing is determined
`by the rules described in the configuration file created when AutoSOCKS is installed. (See
`“Configuring AutoSOCKS.”)
`Because AutoSOCKS intercepts calls to WinSock, AutoSOCKS must duplicate WinSock
`functionality. Since AutoSOCKS also makes calls directly into WinSock, it must behave as a
`typical WinSock application as well. (See Figure 1.)
`
`Figure 1. Network application calls intercepted by AutoSOCKS
`With AutoSOCKS running, an application executes additional steps in order to connect to a
`remote host through WinSock. These steps must be transparent to the application so that it
`cannot differentiate between when AutoSOCKS is running and when it is not. The following
`three steps are identical to standard WinSock communications steps described above;
`however, nested inside them are additional actions and options introduced by AutoSOCKS.
`
`Petitioner RPX Corporation - Ex. 1021, p.11
`
`
`
`•
`
`•
`
`1. The application does a DNS lookup to convert the hostname to an IP address. However, if
`the application already knows the IP address, this entire step is skipped. Otherwise,
`AutoSOCKS does the following:
`If the hostname matches a local domain string or does not match a redirection rule,
`•
`AutoSOCKS passes the name resolution query through to the TCP/IP stack on the
`local workstation. The TCP/IP stack then performs the lookup as if AutoSOCKS is
`not running.
`If the DNS proxy option is disabled, AutoSOCKS allows the request to go through
`unchanged.
`If the destination hostname matches a redirection rule domain name (i.e. the host is
`part of a domain we are proxying traffic to) then AutoSOCKS creates a false DNS
`entry (HOSTENT) that it can recognize during the connection request. AutoSOCKS
`will forward the hostname to the SOCKS server in step 2 and the SOCKS server
`performs the hostname resolution.
`If the DNS proxy option is enabled and the domain cannot be looked up directly,
`AutoSOCKS creates a fake DNS entry that it can recognize later, and returns this to
`the calling application. The false entry tells AutoSOCKS that the DNS lookup
`should be proxied, and that it should send the fully qualified hostname to the SOCKS
`server with the SOCKS connection request.
`2. The application requests a connection to the remote host. This causes the underlying stack
`to begin the TCP handshake. When the handshake is complete, the application is notified
`that the connection is established and that data may now be transmitted and received.
`AutoSOCKS does the following:
`a. AutoSOCKS checks the connection request.
`If the request contains a false DNS entry (from step 1) it will be proxied.
`•
`If the request contains a real IP address and the rules in the configuration file
`•
`say it should be proxied, AutoSOCKS calls WinSock to begin the TCP
`handshake with the server designated in the config file.
`If the request contains a real IP address and the configuration file rules says that
`it should not be proxied, the request is passed to WinSock and processing jumps
`to step 3 as if AutoSOCKS is not running.
`b. When the connection is completed, AutoSOCKS begins the SOCKS negotiation.
`It sends the list of authentication methods enabled in the configuration file.
`•
`• Once the server chooses an authentication method, AutoSOCKS executes the
`specified authentication processing.
`It then sends the proxy request to the SOCKS server. This includes either the IP
`address provided by the application or the DNS entry (hostname) provided in
`step 1.

`
`Petitioner RPX Corporation - Ex. 1021, p.12
`
`
`
`c. When the SOCKS negotiation is completed, AutoSOCKS notifies the application.
`From the application’s point of view, the entire SOCKS negotiation including the
`authentication negotiation, is merely the TCP handshaking.
`3. The application transmits and receives data.
`If an encryption module is enabled and selected by the SOCKS server, AutoSOCKS encrypts
`the data on its way to the server on behalf of the application. If data is being returned,
`AutoSOCKS decrypts it so that the application sees clear text data.
`
`AutoSOCKS Platform Requirements
`AutoSOCKS runs under Windows 3.1, Windows for Workgroups 3.11, Windows 95, and

`
`Petitioner RPX Corporation - Ex. 1021, p.13
`
`
`
`Windows 3.1, Windows for Workgroups 3.11, and Windows NT 3.51
`Windows 3.1, Windows for Workgroups 3.11, and Windows NT 3.51 have similar interfaces.
`AutoSOCKS commands are accessible from the Aventail AutoSOCKS program group and
`from the minimized icon’s System menu when AutoSOCKS is running.
`
`System Requirements
`AutoSOCKS system requirements for Windows 3.1, Windows for Workgroups 3.11, and
`Windows NT 3.51 include the following:
`486-based personal computer
`•

`• AutoSOCKS can be uninstalled using the Uninstall icon in the AutoSOCKS program
`group window.
`• When AutoSOCKS is running in the background, the AutoSOCKS icon is minimized on
`the desktop (unless the Hide Icon command is enabled)
`
`Installation Source Media
`Regardless of platform, AutoSOCKS can be delivered on CD; in a network-delivered, self-
`extracting archive file; or on diskette.
`This runs SETUP.EXE and installs AutoSOCKS. You can specify an installation directory, or
`AutoSOCKS will install in the default AutoSOCKS directory.
`• CD: The CD contains the AutoSOCKS installation program, SETUP.EXE. It also
`contains in the \DOCS directory the AutoSOCKS v2.1 Administration and User’s Guide
`formatted for Acrobat Reader.
`
`10 • AutoSOCKS v2.1 Administration and User’s Guide
`
`Petitioner RPX Corporation - Ex. 1021, p.14
`
`
`
`• Network Delivered Source Media: The network-delivered source media is a self-
`extracting archive containing the required disk/directory structure within the archive file.
`The archive filename will be similar to AS21ED.EXE.
`• Diskette Based Source Media. The diskette based source media is composed of two
`separate disks (labeled Disk 1 and Disk 2) that contain all of the AutoSOCKS installation
`files.
`
`Installing AutoSOCKS
`AutoSOCKS can be installed to a single workstation or to multiple networked workstations. In
`either case, you must perform an initial installation of the software and create one or more
`configuration files. This procedure is described under "Individual Installation." Once the initial
`installation is complete, you can then install to a series of networked computers using the
`instructions and information described under “Network Installation.”
`Note: Check the Quick Start Card for an easy-to-follow guide to individual
`workstation installation.
`
`Configuration Files
`Integral to the initial installation of AutoSOCKS is deciding how SOCKS traffic should be
`redirected through the network. Network redirection rules (used to determine if and how
`SOCKS redirection should occur) are defined in the AutoSOCKS configuration file.
`Configuration files are initially created at the end of the installation process; however; they can
`be added, edited, and removed at any time using the Config Tool (in Windows 3.1, Windows
`for Workgroups 3.11, or Windows NT 3.51 via the System menu in the Aventail Program
`Group; in Windows 95 or Windows NT 4.0 via the Aventail icon in the Taskbar tray). The
`process of creating one or more configuration files is described under “Configuring
`AutoSOCKS.”
`If you are installing AutoSOCKS on multiple networked workstations, refer to “Network
`Installation” to determine the best method for maintaining and distributing configuration files.
`You can then proceed through the initial installation. An Installation Wizard will guide you
`through the steps, culminating with the option to create a configuration file.
`
`Individual Installation
`
`To install AutoSOCKS
`Before running Setup, it is advisable to close all open Windows applications.
`1.
`Installation procedures vary slightly, depending on which media source you use:
`If you are installing directly from CD-ROM, run SETUP.EXE from the AutoSOCKS
`•
`directory (\AS_v21).
`If you are installing directly from diskette, run SETUP.EXE on disk 1.
`
`•
`
`Petitioner RPX Corporation - Ex. 1021, p.15
`
`
`
`•
`
`If you are installing from a network-delivered self-extracting archive, simply run the
`archive file. This will extract the installation files and automatically launch the setup
`program.
`The AutoSOCKS Installation Wizard then guides you through the process of installing
`the AutoSOCKS application.
`2. At the end of the Setup Program you can click the Yes, I want to view the README
`file box in the Setup Complete dialog box. This opens the README file for the latest
`information on AutoSOCKS.
`-OR-
`Simply click the Finish button to complete the Setup Program.
`
`12 • AutoSOCKS v2.1 Administration and User’s Guide
`
`Petitioner RPX Corporation - Ex. 1021, p.16
`
`
`
`3. The setup program will then ask you if you want to restart now or later.
`
`4. After restarting your PC, start AutoSOCKS for the first time.
`5. AutoSOCKS will ask you if you want to run the Configuration Wizard.
`If you select Yes, then the Configuration Wizard will launch to help you create a new
`configuration file.
`If you select No, then AutoSOCKS will ask you to select a configuration file to use.
`6. After creating or selecting a configuration file, AutoSOCKS will now be finished
`installing.
`
`To uninstall AutoSOCKS
`The procedure to uninstall (remove) AutoSOCKS varies depending on whether you are
`running a 16- or 32-bit Windows operating system.
`! To uninstall AutoSOCKS from Windows 95 and Windows NT 4.0, double-click Add/Remove Programs
`in the Control Panel window, select AutoSOCKS from the list of programs on the Install/Uninstall tab, and
`click the Add/Remove button.
`! To uninstall AutoSOCKS on Windows 3.1, Windows for Workgroups 3.11, and Windows NT 3.51, use the
`Uninstall icon in the AutoSOCKS program group.
`
`Network Installation
`In general, the process of installing AutoSOCKS to multiple networked workstations involves
`selection of a file server to use, creation of a staging area for the AutoSOCKS software, and
`copying the AutoSOCKS files to a shared network directory from the source media. Additional
`
`Petitioner RPX Corporation - Ex. 1021, p.17
`
`
`
`options include adding a default configuration file, and
