Unix+clones Getting started with SSH
Post date: February 10, 2006, 23:02 Category: Network Views: 35
Tutorial quote: The following sections hope to provide enough information to setup a user new to ssh with the appropriate files necessary for accessing remote hosts in a secure manner.
Debian ACL(Access Control List) Configuration
Post date: April 4, 2006, 16:04 Category: Installing Views: 21
Tutorial quote: Access Control Lists (ACLs) provide a much more flexible way of specifying permissions on a file or other object than the standard Unix user/group/owner system. Windows NT and above, when running on an NTFS partition, use ACLs to specify permissions on files and directories. This document attempts to show how you can enable ACL support on your Linux box and use Samba to provide an SMB file server for use by machines in a Windows 2000 domain.

ACLs are best stored in the actual file system itself. To that end, there are patches available for ext2 and ext3 that enable ACL support using Extended Attributes (EAs). SGI's XFS also has ACL support built in, but XFS is not currently covered in this document.
Linux Setting Up Subversion for One or Multiple Projects

Debian Packaging Tutorial for Xandros 3.0
Post date: April 12, 2005, 13:04 Category: Miscellaneous Views: 49
Tutorial quote: In this document I will walk you through the process of creating a Debian package for Xandros 3.0. When completed this package will install the Kasablanca FTP client.
Debian Setting up an SSL server with Apache2
Post date: February 12, 2006, 02:02 Category: Network Views: 54
Tutorial quote: With the introduction of the Apache2 packages in Debian it is much simpler to create and use a secure SSL protected webserver than in the old days with Apache 1.3, here we'll show how it is done.
Unix+clones Comparing MySQL performance
Post date: April 12, 2005, 03:04 Category: Benchmarks Views: 57
Tutorial quote: With the introduction of the 2.6 Linux kernel, FreeBSD-5-STABLE, Solaris 10, and now NetBSD 2.0, you might be wondering which of them offers superior database performance. In my previous article, I discussed the tools I chose to test these venerable operating systems and the methodology by which they were tested. The result is this MySQL performance comparison between OpenBSD 3.6; NetBSD 2.0; FreeBSD 5.3 and 4.10; Solaris Express (build 69); and Linux 2.4 and 2.6 (Gentoo-based). Read on for the results.
Debian Setting Up A Highly Available NFS Server
Post date: April 1, 2006, 00:04 Category: Network Views: 23
Tutorial quote: In this tutorial I will describe how to set up a highly available NFS server that can be used as storage solution for other high-availability services like, for example, a cluster of web servers that are being loadbalanced. If you have a web server cluster with two or more nodes that serve the same web site(s), than these nodes must access the same pool of data so that every node serves the same data, no matter if the loadbalancer directs the user to node 1 or node n. This can be achieved with an NFS share on an NFS server that all web server nodes (the NFS clients) can access.

As we do not want the NFS server to become another "Single Point of Failure", we have to make it highly available. In fact, in this tutorial I will create two NFS servers that mirror their data to each other in realtime using DRBD and that monitor each other using heartbeat, and if one NFS server fails, the other takes over silently. To the outside (e.g. the web server nodes) these two NFS servers will appear as a single NFS server.

In this setup I will use Debian Sarge (3.1) for the two NFS servers as well as for the NFS client (which represents a node of the web server cluster).
Gentoo Creating a WebDAV server with apache2
Post date: May 26, 2005, 12:05 Category: Network Views: 289
Tutorial quote: I needed a way to share information (both read and write) as easy as possible with friends in a quite restricted environment (firewall). In many cases, WebDAV which uses standard HTTP port 80 for comunication is a good solution for a file server application.
Linux Secure your Server with iptables
Post date: April 20, 2005, 07:04 Category: Security Views: 96
Tutorial quote: Central to securing a Linux server that's connected to the Internet is having a good firewall and specific policies in place. Numerous options exist for those considering firewalls for Linux, however, a free and included solution is onoffer through Netfilter and iptables.
