This tutorial shows how to prepare a Debian Squeeze (Debian 6.0 ) server for the installation of ISPConfig 3, and how to install ISPConfig 3. ISPConfig 3 is a webhosting control panel that allows you to configure the following services through a web browser: nginx or Apache web server, Postfix mail server, MySQL, BIND nameserver, PureFTPd, SpamAssassin, ClamAV, and many more. The idea is to use the fast and memory efficient nginx web server and Dovecot which is also said to be more memory efficient. You will need to use the Dotdeb repository for nginx.

This can be of interest to people who have a lot of data on a server they need to work on with the tools available on their local machine.

It is much more convenient to access those files like they are stored on your computer than to scp them, or even worse, email them. The tool which allows this is sshfs.

You need to install fuse and sshfs (Debian Squeeze):

1) aptitude install sshfs

Afterwards, add your current user account to fuse group with:

2) adduser mynick fuse

Both previous commands to be executed as root.

Then, mount your remote filesystem with:

3) sshfs remote_host_address:remote_dir localdir/

You can now browse directory tree under the remote_dir from localdir/

There are options you can pass to sshfs, and i find particularly useful

Using ATA Over Ethernet (AoE) On Debian Squeeze (Initiator And Target)

This guide explains how you can set up an AoE target and an AoE initiator (client), both running Debian Squeeze. AoE stands for "ATA over Ethernet" and is a storage area network (SAN) protocol which allows AoE initiators to use storage devices on the (remote) AoE target using normal ethernet cabling. "Remote" in this case means "inside the same LAN" because AoE is not routable outside a LAN (this is a major difference compared to iSCSI). To the AoE initiator, the remote storage looks like a normal, locally-attached hard drive.

This tutorial describes how you can install Apache2 with mod_fcgid and PHP5 on Debian Squeeze. mod_fcgid is a compatible alternative to the older mod_fastcgi. It lets you execute PHP scripts with the permissions of their owners instead of the Apache user.
