Unix+clones Setup the SSH server to use keys for authentication
Post date: November 16, 2005, 15:11 Category: Network Views: 57
Tutorial quote: The user creates a keypair, which consists of a private key, that can be protected with a passphrase, and a public key. The public key is transfered to the server and the private key is kept in our workstation. We assume that the user has accounts in both the server machine and his workstation. Everytime he tries to connect to the server, the keys are validated and the user is granted access.
SuSe A Fresh Approach - SUSE 10.1 package management
Post date: May 12, 2006, 09:05 Category: System Views: 4
Tutorial quote: In SUSE 9.x and 10.0 the default package management software was the software management module and yast online update ( YOU ) in YaST2 and the susewatcher system tray applet. The susewatcher applet would faithfully report any security or system updates and would let you launch YOU to download and apply the updates. For third party software you could add online repositories to the installation sources module and ultimately you could manage all your software from the software management module, again in YaST2.
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).
Debian Automated distributed backups for laptops
Post date: February 14, 2006, 16:02 Category: Network Views: 42
Tutorial quote: This document will describe the setup I made for automating the backup tasks for all laptops here in the house. My servers use the same backup server and infrastructure, but right now they don't have the checks and scripts because they are online 24/7 and my backup server is triggering the backup process. This is however not true at all for the laptops.

Laptops can be at different places, powered down, suspended, put to sleep etc. So I needed a different approach for them.
Unix+clones The 'no-configuration, only-active-when-needed' SSH VPN
Post date: April 12, 2005, 23:04 Category: Network Views: 40
Tutorial quote: So, we started thinking about how we might set up a VPN between the application server and our internal software mirror. The only requirement is that the VPN be initiated from the "inside-out" and that the connection is only active for as long as we need to use. In other words, it would only be active during an administration session. Ideally, it wouldn't be a lot of work to setup and tear down either.

SSH to the rescue...

Fortunately, SSH client and server come with support for this out of the box, requiring no additional software to be installed, and no configuration changes. On the server side, sshd, the setting "AllowTcpForwarding" defaults to "yes" unless your sshd_config file explicitly disables it. On the client side, all you have to do is request the forwarding.
Unix+clones Configuring Apache - Don't Succumb To The "Slashdot Effect"
Post date: January 30, 2006, 22:01 Category: Optimizing Views: 28
Tutorial quote: Like many techno-geeks I host my LAMP website on a cheap ($150) computer and my broadband connection. I have also wondered what would happen if my site was linked on Slashdot or Digg. Specifically, would my setup be able to survive the "Slashdot Effect?" A Pentium 100mhz can easily saturate a T1's worth of bandwidth and my upload speed is capped (supposedly) at 384kbps, so the server should easily be able to handle that. My bandwidth will be saturated before the server is incapacitated, at least that's the idea.
Unix+clones Providing FTP Services with PureFTPd
Post date: April 15, 2005, 17:04 Category: Network Views: 39
Tutorial quote: If you work around computers for any length of time you'll probably run into an FTP server. FTP stands for File Transfer Protocol and FTP servers are used to do just that, transfer files. FTP has been around for a long time, much longer than P2P programs, or the World Wide Web, in its day it was the primary method of sharing files with others on the Internet, and it remains very popular even today. This tutorial will cover the installation and setup of an FTP server using PureFTPd.
OpenBSD Apache - Serving up the Web
Post date: April 11, 2006, 18:04 Category: Network Views: 19
Tutorial quote: The Apache Web Server is installed as part of the OpenBSD base system. This guide will help you configure the web server: (Apache 1.3.12 is released with OpenBSD 2.7 and 1.3.9 with OpenBSD 2.6)

To see how configurable the Apache/OpenBSD combination is we also look at allowing administrators to remotely review the server's status, we setup the system so we allow users on our system to have their own personal web-space. Of course, for the security counscious you probably want to turn some of these things off after you get things up and running.
Unix+clones Setting Up Samba 3.x
Post date: April 15, 2005, 19:04 Category: Network Views: 40
Tutorial quote: Recently I got the opportunity to setup a new lab for a small school. The server runs Linux and the workstations run WindowsXP. There are 3 levels of access on the workstations (admin, teacher, and student) and security on the workstations is based on Windows policies applied at logon.
Unix+clones HOW TO: Setup RoundCube Webmail on Your Server
Post date: February 28, 2006, 02:02 Category: Software Views: 125
Tutorial quote: I recently heard about a new webmail client from my friend Justin, who’s infatuated with it. RoundCube, a “browser-based multilingual IMAP client with an application-like user interface,” is the latest and greatest webmail client.
