Postfix Virtual Hosting With LDAP Backend & Dovecot (IMAP/POP3) On Ubuntu 8.04

Post date: August 3, 2008, 10:08 Category: Installing Views: 2992 Comments
Tutorial quote: I have been running with a MySQL backend for virtual hosting for some time, but when I discovered Phamm and the added FTP feature I decided to switch to LDAP as backend for Postfix with virtual hosting. In view of the fact that the installation and configuration guide of Phamm is lacking some basic information it took me quite some time to put it all together and get it working. Piecing it all together was not simple so I would like to share how I configured it and got it all working toghether.

Get your wireless card working in Ubuntu

Post date: June 3, 2006, 11:06 Category: Network Views: 4513 Comments
Tutorial quote: Okay so you have a wireless card that shows up in ubuntu but doesnt connect to any wireless network?

The reason the card shows up but doesnt work is because ubuntu is distributed with its driver (so it can recognize it) but not with its firmware (so it can USE it) for legal reasons.

However you can take the firmware out of the windows drivers and put them into ubuntu and make the card work
Follow these steps to get your wireless card working under ubuntu dapper 6.06

Wireless networking using the ndiswrapper module

Post date: June 4, 2006, 17:06 Category: Network Views: 5413 Comments
Tutorial quote: Getting wireless networking working with the ndiswrapper driver is fairly straightfoward if your card has an associated Windows driver. Here we'll look at getting wireless networking working for a Dell Inspiron 1300, you should be able to follow the recipe for most other wireless networking cards which are supported ndiswrapper.

ndiswrapper is a collection of utilities which essentially allows you to load and run a network card driver written for Microsoft Windows upon your Linux kernel. This means that a card which isn't supported natively may be used indirectly.

Recover a dead hard drive using dd

Post date: October 23, 2006, 03:10 Category: System Views: 15410 Comments
Tutorial quote: The Unix program dd is a disk copying util that you can use at the command line in order to make a disk image. It makes a bit-by-bit copy of the drive it's copying, caring nothing about filesystem type, files, or anything else. It's a great way to workaround the need for Norton Ghost.

Normally, in order to make a disk image, the disk you're copying from has to be able to spin up and talk -- in other words, it's OK to make a copy if the disk is healthy. But what happens when your disk is becoming a doorstop? As long as it continues to spin, even with physical damage on the drive, dd and Mac OS X will get you out of the fire.

My First Linux Server, Part 2

Post date: April 14, 2005, 22:04 Category: Miscellaneous Views: 3737 Comments
Tutorial quote: A file server is a specialized PC that holds large numbers of files that many people on a network can access. It "serves up" files to everyone instead of each person having files on his or her own PC. The good news is that you don't have to be a network guru to set up a basic file server. If you followed the Easy Linux Install steps in Part 1, you are ready to set up a Linux PC as a file server.

While there are many ways to set up a network and a server, this article concentrates on the simplest approaches with the highest chance of quick success.

Installing FreeNX Server on SUSE 10

Post date: December 27, 2005, 15:12 Category: Network Views: 7166 Comments
Tutorial quote: Not long ago, I reviewed SUSE Linux 10 and found that they had included the latest version of FreeNX (a free version of NoMachine's NX Server) on the installation media. I'd never really tried FreeNX at that point but had heard some good things about it, so I thought I'd give it a shot. Well, once it was installed and working I have to say I was immediately impressed by how simple it was to setup and how well (read: fast) it performed over a WAN connection. I was literally able to get my desktop at home from anywhere else in the world and get near-local speed. Normally, working on a remote system is alright until you need to type in any shape or form. There was almost no delay from the time I'd press a key to the time it would show up on the screen. This is what sold me on FreeNX and prompted me to offer to write a HOWTO on the topic. I was overwhelmed with email from our readers asking that I write it... so here we are!

A web server in a shell script

Post date: March 14, 2006, 08:03 Category: Programming Views: 16515 Comments
Tutorial quote: Suppose you want to experiment a little with web pages and CGI's, but you don't want the hassle of installing the full Apache package. This quick and dirty shell script could just be what you need.

Put simply, a web server is an application that sends local text files over the network to the clients that request them. If you let another program (for example inetd) deal with the network part, the web server could be reduced to a mere cat "$filename" to stdout. Of course, the difficult part would be to extract that filename out of the HTTP request string: nothing that a Bash script cannot easily do!

Building an LDAP Server on Linux, Part 2

Post date: April 15, 2005, 17:04 Category: Network Views: 3635 Comments
Tutorial quote: Welcome back! In Part 1 we learned basic concepts of LDAP and the uses for an LDAP server. Today we'll install and configure an OpenLDAP directory.

A quick note before we get started: this is LDAP 101. We are not installing any kind of encryption or strong authentication; we'll get to that in part 3. In my experience, learning LDAP in small chunks works best. (Then again, perhaps I'm just a bit dim.) So sit back, strap in, and keep your fingers away from the training wheels.

"The wise sysadmin will consult the documentation for their distro; it's quite possible that OpenLDAP will be packaged and ready to go in a pleasing manner (or ready to go in an odd manner--you never know). I'm all for easy--if your particular distribution provides an easy way, use it. RPMs can also be obtained from rpmfind.net, which thoughtfully lists all the required additional packages.

"Debian of course goes its own merry way. apt-get does the job just fine; the tricky bit is finding out the package names. Debian users want ldap-utils; slapd, which is OpenLDAP; and libdb4.1, to get the Sleepycat DB. These three components are enough to get you up and running. apt-get will walk you through a minimal configuration and will automatically start up slapd, the LDAP server daemon.

How To Harden PHP5 With Suhosin On Fedora 7

Post date: July 25, 2007, 23:07 Category: Security Views: 3287 Comments
Tutorial quote: This tutorial shows how to harden PHP5 with Suhosin on a Fedora 7 server. From the Suhosin project page: "Suhosin is an advanced protection system for PHP installations that was designed to protect servers and users from known and unknown flaws in PHP applications and the PHP core. Suhosin comes in two independent parts, that can be used separately or in combination. The first part is a small patch against the PHP core, that implements a few low-level protections against bufferoverflows or format string vulnerabilities and the second part is a powerful PHP extension that implements all the other protections."
