Come back to Ubuntu server on VirtualBox again… Last week, I joined a training of ‘Internet GIS Technology and Web Map Server Development’ .. So this week I really need to install some software in my server.

Normally, I have installed the VirtualBox in my laptop.. So today, I just download a Ubuntu OS and install it!!

I tried to use a Ubuntu desktop 11.04 first but it was very slow (lacking).. then I decided to re-install Ubuntu OS again by using server version .. Yes, it was better.. !!! ..

I don’t know why it is very slow.. I dedicated 1.5GB of memory .. You know, I’m very impressive the Ubuntu version 9.10.. anyway, the change is normal!!

# to load balance between the servers.

After I installed Endian Firewall. I enabled OpenVPN service and I want to connect to private network by OpenVPN Client. And this is workaround :

1. Download file cert.pem from OpenVPN Server. (System Admin can help you.)

2. Install OpenVPN Client.

# sudo apt-get install openvpn

3. If you put your cert.pem on this path /home/your_account_name/openvpn-client/cert.pem when you connect by OpenVPN client you must use this command :

# sudo openvpn –client –pull –comp-lzo –nobind –dev tap0 –ca /home/your_account_name/openvpn-client/cert.pem –auth-user-pass –remote Your_IP_Of_OpenVPN_Server

** This command has one line.

4. It’s complete.
