Linux

  For system and network administrators or other users who frequently deal with sessions on multiple machines, SSH ends up being one of the most oft-used Unix tools. It usually works so well that until you use it for something slightly more complex than starting a terminal session on a remote machine, you tend to use it fairly automatically. However, the ~/.ssh/config file bears mentioning for a few ways it can make using the ssh a client a little easier. Abbreviating hostnames If you often have to SSH into a machine with a long host and/or network name, it can get irritating to type it every time. For example, consider the following command: $ ssh server42371.some.long.hostname.for.a.server.com If you interact with the server42371 machine a lot, you could include a stanza like this in your ~/.ssh/config: Host server42371 HostName server43271.some.long.

It has come to my attention that there is a great wave of people out there that think using kill -9 on everything is a great idea. Who are these people and how did they acquire such an insidious habit? I wish I knew. There exists in Unix a thing called a signal. There are many types of signals that are sent to processes for a great variety of reasons. When a process receives a signal, it may ignore it or catch the signal and execute a signal handler. This is called trapping a signal. Untrapped signals have a default action, which are basicly do nothing or exit. There are two signals that are untrappable, SIGKILL and SIGSTOP. There is a command line utility called kill that simply sends a signal to a process. kill -signal pid will send signal to pid. kill -l will list all of the available

First, a little background. In Unix, compressing (making something smaller) and archiving (combining many things into one) are two different functions. Also, a .tgz file is the same as a .tar.gz file, and a .tbz is the same as a .tar.bz2 file. The most commonly asked question about compression type programs   Why 4 different compression programs? Compress is the standard legacy Unix compression program. gzip has been around for 2 generations of Unix users, it compresses better thancompress, and everyone loves it. Then someone has to do better and create bzip2, which has significantly better compression ratios. However, bzip2 takes longer to work, and can be really slow on large files. And of course, zip is just for compatibility with windows users.   Decompressing Files   How do I decompress a .tar type file? tar xf file.tar How do I decompress a .gz type file? gunzip file.gz

 It might be a bit late for me to post this, as I probably should have done it a few days ago, but I’m doing tonight, regardless. I feel it’s necessary that the users of LFD understand my thoughts and/or opinions about all of this SOPA/PIPA stuff that’s going on. First off let me talk about January 18th, 2012(tomorrow). As many of you know, and for those that don’t know, there is a big blackout going to happen of sites in the United States tomorrow to show the protest against SOPA. Many large sites such as Wikipedia, XDA-Developers, Reddit and thousands and thousands of others. So you ask, what is LFD doing ? The answer is, LFD will be blacked out tomorrow as well. I have decided that I will be doing this with LFD to show my support for the protesting of SOPA/PIPA.

Cinnamon is a very recent addition to the list of desktop environments available for Linux, BSD and other UNIX-like operating systems. It was started by Clement Lefebvre and his crew at Linux Mint and it is an attempt to make the GNOME 3 desktop more user-friendly. If you are not happy with GNOME 3, and are using Fedora 16, that is, the main edition, which uses the GNOME 3 desktop environment, you will find Cinnamon a lot more fun to use. This short tutorial gives the steps on how to install and use it. Installing Cinnamon entails adding the Cinnamon repository to the system. There are two methods of getting that done. The simplest is to run the following command (as root or with sudo): curl http://repos.fedorapeople.org/repos/leigh123linux/cinnamon/fedora-cinnamon.repo -o /etc/yum.repos.d/fedora-cinnamon.repo Then install the cinnamon package by typing (as root or with

I’d like to wish everyone who visits LFD a very safe and happy holiday season. I hope everyone enjoys their time with their families, loved ones and friends over the holidays. It’s also time to enjoy some great home cooking that our loved ones make for us as well. I personally have already enjoyed my holiday season as I’ve had my 9 year old son fly from Houston, Texas to come see me here in Rome, Georgia for 10 days. He arrived on December 17th, and will be here until December 27th. It’s the first time in 4 years that I’ve been able to see him. It’s been the best holiday season in a very long time. I hope everyone else gets something as special as what I got this holiday season as we each certainly deserve it. If you are travelling, please be safe out there

As you have noticed by visiting the site, I’m working on adding a new theme to LFD. It’s currently still very much a work in progress. In fact, there’s a lot of work left to do yet. This theme is completely different from what most of the LFD users are used to. In fact, you’ll notice it’s got a new home page with some information boxes(white boxes) now. There are a few reasons for the theme change. One, is I wanted a more professional theme. This one is actually paid for. I also wanted something that was more image friendly. By that, it adds a bit of a nice touch to the site to see images next to the posts as well as on the home page of the site. Please take note that these are one of the things that are most definitely

I know not everyone celebrates this day, or that they all celebrate on the same day. But over the years I’ve come to know a lot of people and users in the Linux community. And because of that, I’d just like to wish everyone who does celebrate it, a very HAPPY THANKSGIVING!!  There are so many things I have to be thankful for. First and foremost is my father and my son. It’s really the only family I have. But I have friends, and a lot of them. And then of course I also have all of my fans/users of LFD. You all just don’t know how thankful I am for you. I don’t say it often, and for that I do apologize. However, without you, this site would be pointless, and well, probably wouldn’t exist. While I’m not going to drag
