Virtual Hosting With PureFTPd And MySQL (Incl. Quota And Bandwidth Management) On Ubuntu 12.04

Virtual Hosting With PureFTPd And MySQL (Incl. Quota And Bandwidth Management) On Ubuntu 12.04

This document describes how to install a PureFTPd server that uses virtual users from a MySQL database instead of real system users. This is much more performant and allows to have thousands of ftp users on a single machine. In addition to that I will show the use of quota and upload/download bandwidth limits with this setup. Passwords will be stored encrypted as MD5 strings in the database. This tutorial is based on Ubuntu 12.04.

Configure An Email Gateway With Scrollout F1 Anti-Spam & DLP

Configure An Email Gateway With Scrollout F1 Anti-Spam & DLP

An email gateway (a.k.a. firewall) is a machine (physical or virtual) installed between Internet and the email server. Its primary role is to protect the email server by filtering incoming messages, via SMTP protocol, from Internet. Secondary, an email gateway may be used as an outgoing gateway in case you want to add some new email features which are not provided by older email servers. For instance, Exchange 2000 or 2003 has no DKIM signing and verification service – a quality improvement for message delivery. This tutorial shows how to configure an email gateway with the Scrollout F1 email gateway.

Basic configuration covered by video tutorial.

OpenVZ: Mounting Host Devices/Partitions/Directories In A Container With Bind Mounts (Debian/Ubuntu)

Sometimes you are in a situation where you need to mount a hard drive, partiiton or directory from the OpenVZ host inside an OpenVZ container - for example, you add a fast SSD to the host and want to put your container's MySQL databases on it to make MySQL faster. This tutorial explains how you can mount host devices/partitions/directories in an OpenVZ container with bind mounts.

The Perfect Desktop - Kubuntu 12.04

The Perfect Desktop - Kubuntu 12.04

This tutorial shows how you can set up a Kubuntu 12.04 desktop that is a full-fledged replacement for a Windows desktop, i.e. that has all the software that people need to do the things they do on their Windows desktops. The advantages are clear: you get a secure system without DRM restrictions that works even on old hardware, and the best thing is: all software comes free of charge.

Striping Across Four Storage Nodes With GlusterFS 3.2.x On Ubuntu 12.04

Striping Across Four Storage Nodes With GlusterFS 3.2.x On Ubuntu 12.04

This tutorial shows how to do data striping (segmentation of logically sequential data, such as a single file, so that segments can be assigned to multiple physical devices in a round-robin fashion and thus written concurrently) across four single storage servers (running Ubuntu 12.04) with GlusterFS. The client system (Ubuntu 12.04 as well) will be able to access the storage as if it was a local filesystem. GlusterFS is a clustered file-system capable of scaling to several peta-bytes. It aggregates various storage bricks over Infiniband RDMA or TCP/IP interconnect into one large parallel network file system. Storage bricks can be made of any commodity hardware such as x86_64 servers with SATA-II RAID and Infiniband HBA.

Managing A Headless VirtualBox Installation With phpvirtualbox (Ubuntu 12.04)

Managing A Headless VirtualBox Installation With phpvirtualbox (Ubuntu 12.04)

phpvirtualbox is a web-based VirtualBox front-end written in PHP that allows you to access and control remote VirtualBox instances. It tries to resemble the VirtualBox GUI as much as possible to make work with it as easy as possible. It is a nice replacement for the VirtualBox GUI if you run VirtualBox on headless servers. This tutorial explains how to install phpvirtualbox on an Ubuntu 12.04 server to manage a locally installed, headless VirtualBox.

Using mod_spdy With Apache2 On Ubuntu 12.04

Using mod_spdy With Apache2 On Ubuntu 12.04

SPDY (pronounced "SPeeDY") is a new networking protocol whose goal is to speed up the web. It is Google's alternative to the HTTP protocol and a candidate for HTTP/2.0. SPDY augments HTTP with several speed-related features such as stream multiplexing and header compression. To use SPDY, you need a web server and a browser (like Google Chrome and upcoming versions of Firefox) that both support SPDY. mod_spdy is an open-source Apache module that adds support for the SPDY protocol to the Apache HTTPD server. This tutorial explains how to use mod_spdy with Apache2 on Ubuntu 12.04.

Distributed Storage Across Four Storage Nodes With GlusterFS 3.2.x On Ubuntu 12.04

Distributed Storage Across Four Storage Nodes With GlusterFS 3.2.x On Ubuntu 12.04

This tutorial shows how to combine four single storage servers (running Ubuntu 12.04) to one large storage server (distributed storage) with GlusterFS. The client system (Ubuntu 12.04 as well) will be able to access the storage as if it was a local filesystem. GlusterFS is a clustered file-system capable of scaling to several peta-bytes. It aggregates various storage bricks over Infiniband RDMA or TCP/IP interconnect into one large parallel network file system. Storage bricks can be made of any commodity hardware such as x86_64 servers with SATA-II RAID and Infiniband HBA.

Ubuntu 12.04 Samba Standalone Server With tdbsam Backend

Ubuntu 12.04 Samba Standalone Server With tdbsam Backend

This tutorial explains the installation of a Samba fileserver on Ubuntu 12.04 and how to configure it to share files over the SMB protocol as well as how to add users. Samba is configured as a standalone server, not as a domain controller. In the resulting setup, every user has his own home directory accessible via the SMB protocol and all users have a shared directory with read-/write access.

VBoxHeadless - Running Virtual Machines With VirtualBox 4.1 On A Headless Ubuntu 12.04 Server

VBoxHeadless - Running Virtual Machines With VirtualBox 4.1 On A Headless Ubuntu 12.04 Server

This guide explains how you can run virtual machines with VirtualBox 4.1 on a headless Ubuntu 12.04 server. Normally you use the VirtualBox GUI to manage your virtual machines, but a server does not have a desktop environment. Fortunately, VirtualBox comes with a tool called VBoxHeadless that allows you to connect to the virtual machines over a remote desktop connection, so there's no need for the VirtualBox GUI.
