Install aplikasi GUI utuk client
# apt-get install kvpnc
# apt-get install network-manager-openvpn openvpn
Copy setting OpenVPN
# cp -Rf /usr/share/doc/openvpn/examples/easy-rsa/* /etc/openvpn/
Pada Ubuntu Hardy 8.04 tampaknya ada beberapa versi konfigurasi, kita dapat menggunakan salah satu dengan cara
# cp -Rf /etc/openvpn/2.0/* /etc/openvpn/
Selanjutnya lakukan langkah berikut, yang sama dengan versi lainnya
# cd /etc/openvpn
# mkdir /etc/openvpn/keys
Lakukan langkah berikut
# vi vars
# , ./vars
# ./clean-all
Atau copy file /etc/openvpn/vars dari Server. Copy key client dari Server
# scp -r root@192.168.0.3:/etc/openvpn/keys/ca.crt /etc/openvpn/keys
# scp -r root@192.168.0.3:/etc/openvpn/keys/user1.crt /etc/openvpn/keys
# scp -r root@192.168.0.3:/etc/openvpn/keys/user1.key /etc/openvpn/keys
