The GWU ISS simply ignores the Linux users’ need on GWireless, there is no resource, no support for Linux user. From the screenshot of VPN client on Mac OSX platform, we can conclude that GWireless is secured by Cisco VPN client.
For Gentoo users, just
sudo emerge cisco-vpnclient-3des
You might need to fill several forms for Cisco before you login and download vpnclient-linux-x86_64-4.6.03.0190-k9.tar.gz. Or you can get it from here. Copy it to /usr/portage/distfiles, and re-run the previous command.
For other users who are using latest kernel-2.6.14, you need to apply this
patch, since 2.6.14 has changed the
sk_buffer data structure, then
make sudo ./vpn_install
After that, you need to copy the
profile from one Windows installation to
/etc/opt/cisco-vpnclient/Profiles, and make it worldwide readable.
sudo /etc/init.d/vpnclient start vpnclient connect gwireless
Update Due to the agreement of the Cisco VPN client, the profile file is removed, thanks to Mackenzie.
