Leave a reply

# Tested using CentOS 6 32-bit openvz
# default user root

# Build a scrambled openvpn server
# Loads patch to scramble openvpn, to bypass blocking

# When you first access your OpenVZ
# Turn on TUN, in management console, by default its usually turned off.
# When you reinstall OS system, I found I needed to turn TUN off and on again
