Cisco AnyConnect VPN Client, Release 2.4 Overview

Cisco® AnyConnect Virtual Private Network (VPN) Client provides remote users with full network access to virtually any
corporate application. It automatically adapts its tunneling protocol to the most efficient method based on network
constraints. Cisco AnyConnect VPN Client is the first VPN product to use the Datagram Transport Layer Security (DTLS)
protocol to provide an optimized connection for latency-sensitive traffic, such as Voice Over IP (VoIP) traffic or TCP-
based application access.


Authorized Users

Anyone with active O-Key credentials can access the OSU VPN Client through website login. The VPN Client is used for
the access of on-campus equipment that is joined to the OSU Network.


Operating System Support

Cisco AnyConnect VPN Client supports the following operating systems:
        • XP 32-bit (x86) and 64-bit (x64)
        • Windows Vista 32-bit (x86) and 64-bit (x64), including Service Pack 1 and 2 (SP1/SP2)
        • Windows 7 32-bit (x86) and 64-bit (x64)
        • Mac OS X 10.5 and 10.6.x
        • Linux Intel (2.6.x kernel)
        • Windows 2000 & Mac OS X 10.4 are no longer validated / supported as of AnyConnect 2.4. Cisco AnyConnect
        Mobile (requires optional AnyConnect Mobile license)
        • Windows Mobile 5.0, 6.0, and 6.1 (Professional and Classic


System Requirements

AnyConnect does not support virtualization software such as VMWare for any platform or Parallels
Desktop for Mac OS. AnyConnect 2.4 running over VMware or Microsoft Virtual PC on Windows 7 is
not 100% reliable, but initial testing suggests the results are usually favorable.

AnyConnect does not support sessions with a security appliance running on the same subnet as the
endpoint.


Microsoft Windows

For WebLaunch, use Internet Explorer 6.0+ (with enabled Active X) or Firefox 2.0+ (with Sun JRE 1.4+ installed).
Windows Requirements:
       • Pentium class processor or greater.
       • x64 or x86 processors.
       • 5 MB hard disk space.
       • RAM:
               – 256 MB for Windows XP.
               – 512 MB for Windows Vista.
               – 512 MB for Windows 7.
       • Microsoft Installer, version 3.1.


                                                            2
Mac OS

For WebLaunch, use Safari or Firefox 2.0+ (both need Sun JRE 1.4+).
AnyConnect downloads the proxy settings configured in the group policy to the Safari browser after the tunnel is
established. The settings return to their original state after the VPN session ends.

AnyConnect 2.4 supports the following versions of Mac OS:
      • Mac OS X 10.5
      • Mac OS X 10.6 and 10.6.1 (both 32-bit and 64-bit).
      AnyConnect requires 50MB of hard disk space.


Linux
AnyConnect supports only standalone installations on Linux. The following sections show the supported Linux
distributions and requirements.

        Linux Distributions:
                • Red Hat Enterprise Linux 5 Desktop
                • Ubuntu 9.x

        Linux Requirements:
                • x86 instruction set.
                • 32-bit or biarch 64-bit processor—standalone mode only; web-based install/connect is not supported.
                • 32 MB RAM.
                • 20 MB hard disk space.
                • Superuser privileges.
                • libstdc++ users must have libstdc++ version 3.3.2 (libstdc++.so.5) or higher, but below version 4.
                • Firefox 2.0 or later with libnss3.so installed in /usr/local/lib, /usr/local/firefox/lib, or /usr/lib. Firefox
                must be installed in /usr/lib or /usr/local, or there must be a symbolic link in /usr/lib or /usr/local called
                firefox that points to the Firefox installation directory.
                • libcurl 7.10 or later.
                • openssl 0.9.7a or later.
                • java 1.5 or later. The default Java package on Fedora is an open-source GNU version, called Iced Tea on
                Fedora 8. The only version that works for web installation is Sun Java. You must install Sun Java and
                configure your browser to use that instead of the default package.
                • zlib or later.
                • gtk 2.0.0, gdk 2.0.0, libpango 1.0.
