Finding Remote Network File Systems
Using a Network Files System (NFS) is a common method for sharing drive space on UNIX-like systems such as Linux.
Although relatively easy to configure, it's also easy to forget the NFS mounts of several systems on a large network.

Installing ehcp (Easy Hosting Control Panel) On Any Debian Or Apt-Get Based Distro, Including Ubuntu
In this tutorial I will show you howto install ehcp on any debian based distro, or any distro that has apt-get support.
ehcp stands for Easy Hosting Control Panel. It may be used by anyone wanting to host multiple domains in his dedicated/vps server. It is a hosting control panel under development.
Open a console, and become superuser by su or sudo bash,
Then, issue following commands to download ehcp and install it:
wget http://www.ehcp.net/download
tar -zxvf ehcp_latest.tgz
cd ehcp
./install.sh
You will be asked a few questions, such as your server IP, your hostname,installation script will detect your IP, if it can, enter your IP, if it is not detected, or if your are behind a gateway, such as an ADSL modem.
While installing, you will be asked for your MySQL password. If it is empty, or if you installed MySQL the first time, just press enter; if it is not empty, enter your pass when prompted.
The installer asks you some questions, such as your desired password for admin password, ehcp mysql user password. you can choose any password for them. But make sure that mysql root password is is correct for your server. if you dont have mysql installed before, then ehcp will take care of that..
Installation mainly uses apt-get to install components, and makes any additional settings that are needed. At the end, you will be provided with the ehcp login page in your Firefox window, if you are on your local machine, otherwise, you need to connect to your new webserver by entering the IP address of you server, such as: http://yourip/vhosts/ehcp
Your default admin username: adminDefault admin pass: 1234
You may change your admin pass after the first login.
