# Juniper VPN Script based on openconnect

# The following packages are required for this to work:
# gksu zenity libssl-dev libxml2-dev vpnc-scripts
# 
# As well as a custom build of openconnect:
#
# wget ftp://ftp.infradead.org/pub/openconnect/openconnect-7.06.tar.gz
# tar xzf openconnect-7.06.tar.gz{
# cd openconnect-7.06
# ./configure --with-vpnc-script=/usr/share/vpnc-scripts/vpnc-script
# make
# sudo make install
