Minecraft Black screen fix on 64bit Linux

I recently reinstalled 64bit Linux on a new SSD drive on my desktop and ran into another Black Screen issue, similar to my black screen issue i had about 2 years ago.

This time i was getting the following error:

Exception in thread "Thread-3" java.lang.UnsatisfiedLinkError: /home/******/.minecraft/bin/natives/liblwjgl.so: /home/******/.minecraft/bin/natives/liblwjgl.so: wrong ELF class: ELFCLASS32 (Possible cause: architecture word width mismatch)

Creating the following bash script fixed my issue:

java -jar minecraft.jar

    Installing AirPWN 1.4 on Ubuntu 10.04 LTS and 10.10


    What is AirPWN?

    AirPWN? is a tool that first debuted at DefCon 12.

    AirPWN? acts as a man in the middle tool for wireless networks. It takes advantage of the time that a website takes to respond to normal page requests. In that lag time, it can inject its own content onto the wireless channel of an access point. For instance, you may request a page from wikipedia.org that takes, round-trip, approximately 125 ms. If someone near you is running the airpwn tool, it will see your request and immediately respond with its own web page and/or content because it is much closer and takes much less time to respond. When your computer receives the data, it will think the original request was answered and display the page. When the real web page is presented, it will either ignore the page, or display some of the content. AirPWN? can be configured to carefully craft responses so that your browser will ignore the real web content as it would with html comments.

    In this article i walk you through installing AirPWN on Ubuntu Linux 10.04 and 10.10.

    Read on for more.

    Install Synchronet BBS on Ubuntu Server


    Synchronet Bulletin Board System Software

    ... is a free software package that can turn your personal computer into your own custom online service supporting multiple simultaneous users with hierarchical message and file areas, multi-user chat, and the ever-popular BBS door games.

    Synchronet development began as a personal hobby in 1990 for single-tasking MS-DOS compatible computers and Hayes compatible modems. The program was sold commercially from 1992-1996 after which time it was released (with source code) for both the 16-bit DOS and 32-bit OS/2 platforms to the public domain and development by the author was ceased.

    In November of 1999, the author found a renewed interest in further developing Synchronet, specifically for the Internet community, embracing and integrating standard Internet protocols such as Telnet, FTP, SMTP, POP3, IRC, NNTP, and HTTP. Synchronet has since been substantially redesigned as an Internet-only BBS package for Win32 and Unix-x86 platforms and is an Open Source project under continuous development.

    Synchronet Version 3.1x for Win32 and Unix (Intel-x86 architecture) can be previewed on Vertrauen (Home of Synchronet BBS Software).

    In this article, i walk you through installing the Synchronet BBS Software on a Ubuntu Server.

    Video Tutorial: Installing Aircrack + Wicrawl on Ubuntu Linux




    Aircrack-ng is a set of tools for auditing wireless networks. These tools can recover 802.11 WEP and WPA-PSK keys once enough data packets have been captured. It implements the standard FMS attack along with some optimizations like KoreK attacks, as well as the all-new PTW attack, thus making the attack much faster compared to other WEP cracking tools.

    Last year i walked you through installing the Aircrack-ng suite on Ubuntu Linux.

    We will be installing and using just part of the Aircrack-ng suite, airmon-ng. This will allow us to put our wireless card into "Monitor" mode.


    Wicrawl is a simple wi-fi (802.11x) Access Point auditor with a simple and flexible plugin architecture. The plugins allow us to find out useful information about an AP so we don’t have to manually check each access point. Plugins are implemented for existing common tools, and new plugins can be written in any language. Wicrawl is able to use multiple cards, and eventually will be able to use multiple computers.

    The goal is to automate the tedious task of scanning wi-fi access points for interesting information. This can be a useful tool for penetration testers looking to “crawl” through massive numbers of APs looking for interesting data. Plugins will be everything from DHCP and nmap to aircrack or hooks to move a motorized directional antenna around.

    The guys over at Midnight Research Labs stopped development back in 2007. Being a bit out-dated, it wouldn't compile on the latest Ubuntu without a couple tweeks. I replaced the entire source code in the Aircrack-ng plugin folder with the latest SVN (as of this post). I also had to add a header file to the discovery folder to help it compile.

    I went ahead and tared up my folder with all of these edits so you can easily compile it on the latest Ubuntu Linux (9.10 as of this post).

    In this video tuorial, i walk you through installing Aircrack-ng as well as Wicrawl.

    Monitoring & Update email notification via GMail on Ubuntu Linux Servers


    System notification emails

    Continuing in part off of my last Ubuntu Server article, "The Perfect Server", I decided that i wanted the server to send me emails updating its status with me. If the HD space gets low, the RAM is all used up, services go down, or even i lose internet at my house while im out and about, i get a nice email from my server notifying me of the problem (at least when my inet comes back online).

    What better way to top this off than with use of a gmail account that i already owned and used?

    In this article, i will walk you through installing the following along side your postfix installation:

    Self signed SSL certfication (don't want anyone being nosey!)

    Apticron - A nice set of scripts that will execute 'apt-get udpate' and email you the results

    Webmin - One of the best web based management consoles for head-less servers. Has a great system notification setup, along with many many many other goodies.
