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

How to secure VNC remote access with two-factor authentication

Post date: May 21, 2007, 22:05 Category: Security Views: 3234 Comments
Tutorial quote: VNC is the most popular remote access solution today. However, it was developed to provide remote access, not to provide secure remote access. Administrators have to add security to VNC by tunneling it through an encrpyted channel such as SSH and adding a layer of authentication. In this article, we will show you how to combine the NoMachine NX server to encrpyt VNC and remote X session combined with two-factor authentication from WiKID Systems to create a secure, fast remote access solution.

Apache - Serving up the Web

Post date: April 11, 2006, 22:04 Category: Network Views: 7313 Comments
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.

Post date: September 2, 2009, 13:09 Category: Software Views: 3623 Comments
Tutorial quote: Kismet is a 802.11b wireless network sniffer. It is capable of sniffing using almost any supported wireless card using the Airo, HostAP, Wlan-NG, and Orinoco (with a kernel patch) drivers.Kismet identifies networks by passively collecting packets and detecting standard named networks, detecting (and given time, decloaking) hidden networks, and infering the presence of nonbeaconing networks via data
traffic.

Rebuilding the OpenBSD kernel

Post date: April 24, 2005, 20:04 Category: System Views: 4105 Comments
Tutorial quote: Users who want their OpenBSD machine to perform specific functions or need additional device drivers might want to customize their kernel. In other OS's, like some types of Linux, it is very popular to rebuild the kernel because the default is so bloated. For most users, the default OpenBSD kernel is sufficient; however, you should still apply kernel patches, which will require rebuilding and installing a fresh kernel.

How to get ath5k working on Jaunty with Compat-wireless and a self-compiled kernel

Post date: May 27, 2009, 07:05 Category: Software Views: 3249 Comments
Tutorial quote: I used to have some trouble while setting up my Atheros PCI card on Ubuntu Linux 9.04. It worked natively on Ubuntu 8.04, where it was detected as ath0. I upgraded from 8.04 to 8.10 whereby I noticed my wireless PCI card didn’t work natively anymore. Someone suggested me to upgrade from 8.10 to 9.04 Jaunty, and I did that immediately. After the system upgrade I noticed again that my wireless device was gone in Ubuntu 9.04. When I ran iwconfig I didn’t see wlan0 or ath0 anymore.
