Even More Linux Distros That Don’t Suck

Frank — Tue, 07 Sep 2010 03:39:16 +0000

Following my first two distro lists; Linux Distros That Don’t Suck and More Linux Distros That Don’t Suck, I bring you the long awaited third installment in my distro lists; Even More Linux Distros That Don’t Suck.

As a fore-warning, this list is just what I have used in the past and what I have experience with. I know that talking Linux is like talking religion, everyone has one and not everyone likes the other guy’s. With that in mind you are free to comment and hammer me about my list, just know that it’s only my personal experience here.

Mint – What can I say, it’s Ubuntu done right. If what you are looking for is a solid desktop replacement OS, one the whole family can use then look no further. Based on Debian and Ubuntu, this distro comes with everything you need to get going and it looks sexy as well. It’s got full multimedia support right out of the box and it’s super easy to use. Perfect for grandma.

ZeroShell – This distro is awesome. I have used this multiple times on embeded devices and it’s always come through for me. It’s fully administered via a web page and it offer’s a host of network services like Load Balancing, UMTS/HSDPA 3G modem connections, QoS and Lan-to-Lan VPN just to name a few. If you need a solid industrial all around firewall/gateway this should be at the top of your list.

Tiny Core – If you think Damn Small Linux is bloated then Tiny Core is for you. At a whopping 10MB with a full desktop, this has to be the smallest release I have ever seen. If 10MB is too big for you, you can grab a 6MB version that is console only. This is an awesome distro if you want to start small and build on it. Perfect for those older systems.

Elive – Based on Debian, Elive looks to provide a complete desktop replacement while offering eye-candy with minimal hardware requirements. I have this installed on an older laptop that my daughter uses. She loves to work with multimedia and this distro scratches her itch perfectly. It’s runs well on older hardware while still looking good. If you like to work with video, 3D or audio then you should give this distro a once over.

Mythbuntu – It’s really not a distro per-say, it’s a custom roll of Ubuntu with MythTV built it. For years I used KnoppMyth for my MythTV needs and only recently did I switch to Mythbuntu. If you don’t feel like building your HTPC from scratch take a look at this, you won’t be disappointed.

Tinfoil Hat – For the truly paranoid. As their website says “The Illuminati are watching your computer, and you need to use morse code to blink out your PGP messages on the numlock key.”. This distro is perfect for those who fear for their privacy. It’s compiled with static libraries and ships on a single floppy.

LegacyOS – This was formally known as TeenPup which is based on PuppyLinux. The main purpose of this distro is to ensure a smooth user experience on hardware that’s 5-10 years old. If you have an old machine laying around and are looking for a decent suite of software then look no further. Don’t plan on doing any intense processing with it but basic usage it’s great.

As always this is a list of distros I have experience with, this by no means is a “perfect” or “greatest” list. It’s just stuff I have used and like, feel free to let me know what you think in the comments.

More Linux Distros That Don’t Suck

Frank — Tue, 06 Oct 2009 23:56:37 +0000

Following Linux Distros That Don’t Suck from earlier this year here is a comprehensive list of, you guessed it, more Linux Distros that don’t suck. Some of these are more obscure lesser known distros that are quite powerful and very useful. Some of these come from personal use some of them came from the great comments you readers posted the first time I did this.

Remember that this is just a personal list, nothing more, nothing less. I’m not trying to start a holy war since that’s what usually happens when you open something like this up. With that being said, let’s us know in the forums what your list of Linux Distros That Don’t Suck would be.

SLAMPP – A Slackware based Live DVD that can only be described as a one-stop server system. Right off the DVD your up and running with pre-configured services including an HTTP server, FTP server, DHCP server, DNS server and a whole lot more. This is the perfect Distro for those “I really don’t know when I will need a fully functional small network server” times. Best of all, you can run it all without ever having to install anything on the host machine.

Pardus – Pardus, which is the scientific name for the the Anatolian Leopard (watch out Apple), is a Turkish Linux distro which is extremely underrated. It’s wonderfully crafted and has a lot of polish to it. You can tell that the developers have really put a lot of time and energy making this not only run really well but also make it really sexy. I would easily recommend this distro to novices and experts alike.

CrunchBang – Think of CrunchBang as Ubuntu for the advanced. It offers speed and style as well at the bleeding edge of packages. It’s highly customizable and comes with the nimble openbox window manager. No bloated Gnome or KDE here. This is the perfect distro if you really like Ubuntu but don’t like how it’s geared towards linux n00bs.

Sabayon – Sabayon promises to transform your computer into a powerful Gentoo Linux system in under 5 minutes. It’s a livecd (with the option to install) of the uber geek popular Gentoo. It’s very powerful and very polished like you would expect from any Gentoo system, but best of all it still acts like an other Gentoo system allowing you to use portage to pull from the Gentoo repositories.

PC-BSD – Alright, I know it’s technically not Linux, it’s BSD based, but it tries really really hard to be Linux. If you are more of a BSD fan but like the Desktop functionality that a standard linux distro offers then PC-BSD is perfect for you. Much like any out of the box distro you can listen to music, watch some video, work with office documents and you can even install applications with a gui. Best of all, it’s a rock solid BSD core that powers everything.

CentOS – Based on the rock solid RHEL, CentOS is one of the most reliable distros you will every find. It offers quick errata, package management that offers stable applications and has a very strong community behind it. They even get upstream fixes from RHEL. If you want a solid server based OS you can’t do much better than CentOS.

Slackware – The oldest of the bunch. Created in 1992, Slackware is the oldest surviving distro. It orginally came on 24 floppy disks as was built on top of kernel 0.99 and it was one of the hardest things to install. Thank God that things have changed. It’s now a highly technical and clean distro. No fancy tools for settings, you have to do everything by editing text files. You know what they say, if you learn Ubuntu you know Ubuntu. If you learn Slackware you know Linux.

There you go, another list of distros that don’t suck (according to me). You millage may vary. I really don’t want to start a holy war so I open it up to you to add to the list by visiting our forums and letting us know what you like.

Ubuntu 9.10 Beta

Frank — Sun, 04 Oct 2009 06:31:40 +0000

The world’s most popular Linux Distro just got a bit older. Ubuntu 9.10 code named Karmic Koala is quickly reaching it’s maturity date of October 29th when a full stable release will go out.

If you have never used Linux Ubuntu is one of the easiest distro’s to use. It’s quick and easy to install plus it’s probably the most Windows like experience you will get if your coming from a machine running a Microsoft OS. If you are a Linux n00b then you might want to wait till it comes out of beta before you dive in.

Linux Distros That Don’t Suck

Frank — Fri, 15 May 2009 20:44:43 +0000

I, much like every other hardcore geek on the face of the earth, have multiple linux based distro iso’s laying around. Some of them are for testing and some of them contain tools that I use on a daily basis. I have had many people email me about the best distro out there. The only answer I have for them is “depends on what you want to do”. I have spent sometime working on a list of Linux distros and what they are good for.

Now, before I start. Discussion distro’s with people is like discussion religion. Everyone has one and everyone feels something different towards other people who aren’t of the same faith. I just want to remind everyone that this list is just what I see, and how I feel about each distro. It’s definitely not a “what’s right and what’s wrong” type of list. Enjoy.

Knoppix – The one that started it all. Knoppix was the first major LiveCD based distro to hot the scene and open up a whole new world of bootable operating systems. This is probably the best known and most complete LiveCD distro out there. It contains everything you need to act as a full production replacement system. Word Processing, graphics editors, media players, browers, mail clients. You name is, Knoppix has it.

SystemRescueCD – This one I keep with me all the time. SystemRescueCD is a massive collection of tools to help you get out of a bind. It aims to provide an easy way to carry out admin tasks on your computer, such as creating and editing the partitions of the hard disk. It contains a lot of system tools (parted, partimage, fstools, …) and basic tools (editors, midnight commander, network tools). It is very easy to use. Plus, it can also be booted via a USB flash drive. A must for anyone’s collection.

Dynabolic – Billed as a complete media distro, dyne:bolic is shaped on the needs of media activists, artists and creatives as a practical tool for multimedia production: you can manipulate and broadcast both sound and video with tools to record, edit, encode and stream, having automatically recognized most device and peripherals: audio, video, TV, network cards, firewire, usb and more; all using only free software!. Just boot off the CD and your ready to go.

BackTrack – The king of all penetration testing and security distros. If you’re worried about security or exploits then this is the one for you. With more than 300 different up-to-date tools which are logically structured according to the work flow of security professionals. This structure allows even newcomers to find the related tools to a certain task to be accomplished. New technologies and testing techniques are merged into BackTrack as soon as possible to keep it up-to-date.

NimbleX – This is one of my favorite all around LiveCD based distros. It’s full featured but a lot smaller than something like Knoppix. With everything you need to act as a Desktop replacement in a 200 MB CD image, what more can you ask for.

Gentoo – The hardcore Linux distro. What makes Gentoo unique compared to other distros is the need to manually compile every part of the OS. I know that their are gui installers now and pre built packages for the mindless, but having the ability to tweak and optimize every aspect of the OS will not only give you a stable system, but one hell of a quick one too. Mind you, all of this compilation could easily take you days before you have a base system, especially when you make Xorg and a windows manager like KDE or gnome.

Debian – My day to day OS. Debian is one of the oldest and most stable distros around. The core to a bunch of other distros like Knoppix and Ubuntu. If your looking for something that will give you no headaches and carries a very stable branch of applications, Debian is the distro for you.

Ubuntu – Ubuntu is Debian to the next level. It’s a fork of Debian that has quickly become the most popular Linux distro in the world. It’s easy to install, easy to use, and is probably the best Windows replacement OS that is Linux based. Ubuntu’s software repository contains applications that are more recent than say Debian, but the down side to that is the fine edge you walk on when it comes to stability.

Fedora – The big boy on the block, and by big boy I don’t mean popularity, I mean in size. Fedora comes chalked with what seems like every application ever made. Although to some this might be nothing more than bloat, to others it’s a full and complete experience. Install Fedora and you pretty much have every open source application that is useful at your finger tips. If you have never experienced Linux before this is a great distro to get your feet wet with.

I know there are other great distro’s like Slackware, DSL, and OpenSUSE, this list is just a collection of distro’s that I find useful or that I have had experience with. Feel free to add your recommendations in the comments.

Turn An Old TiVo Into A HTPC

Frank — Sat, 11 Oct 2008 03:05:23 +0000

One of the toughest things about building a home theater PC is finding the right case, one that doesn’t stick out like a sore thumb in your media center. This guy gutted out an old TiVo he had laying around and jammed in all the components required to get a PC up and running. He added a copy of Ubuntu running XBMC to finish off the project.

Doesn’t look like it’s that hard to accomplish and might just be the perfect weekend project for someone who is looking to either build a HTPC or remodel one they already have running.

Billix – Linux Swiss Army Knife

Frank — Thu, 28 Aug 2008 02:03:39 +0000

Billix is a multi-boot Linux based distribution that is more-or-less a swiss army knife for system administrators.

You copy Billix onto a CDROM or USB stick and voila, a multitude of bootable/installable Linux distributions. You boot your CDROM or USB key and Billix boots to a boot menu that allows you to book or install the following distros:

Damn Small Linux
Ubuntu 7.04 (Feisty Fawn)
Ubuntu 6.10 (Edgy Eft)
Ubuntu 6.06 LTS (Dapper Drake)
Debian 4.0
Debian 3.1
Centos 5
Centos 4.4
memtest
DBAN

You can download a copy of Billix from their project page.

How To Speed Up WordPress With Nginx And WP Super Cache

Frank — Tue, 12 Aug 2008 03:43:16 +0000

Edit: Fixes suggested in the comments have been applied to this howto

We recently moved tech.nocr.at over to a bunch of VPSs in order to achieve some decent load balancing and speed. Even though SliceHost isn’t a sponsor, I’d like to give them a quick plug. SliceHost is easily the greatest VPS provider bar none. You pick the Distro you want, you tweak it, you set it up, all ports are available, you do as you wish. If you setup multiple VPS with them you can even have private IP’s between them in order to load balance or cluster. Prices start as low as $20/month. If you use them, click this link so that I can get some referral love. Now on to the article..

WordPress can be a blessing and a pain at the same time. It’s great for displaying dynamic content yet it’s displaying that exact dynamic content that can put a massive stress load on your system. WordPress’s query routines aren’t exactly the best. Let’s not even go into how much of a hog Apache can be, but for running dynamic content and prettying up your url’s, mod_rewrite can’t be beat. By using WP Super Cache to help reduce the load on your SQL queries and by placing Nginx in front of Apache as a reverse proxy, you’d be amazed and how quickly your site will load and respond, even enough to withstand a digg of slashdot effect.

Here’s what you are going to need.

This how-to system assumes that you have your Webserver running under a debian style distro like Ubuntu, but It can easily be modified for other distros like Fedora or CentOS.

Assuming that you already have WordPress running under Apache the first thing we are going to do is install the Wp-Super-Cache plugin and active it under your plugin folder of your WordPress installation. Pay close attention to the installation steps in the included readme.txt file, you have to follow each step properly in order to ensure proper caching.

Wp-Super-Cache creates static html files of your pages lessening the load on your SQL queries. Once you have it running and working let’s move on to our next step, reconfiguring Apache.

Apache can be a resource hog, especially when it has to span multiple child processes in order to serve up content. We are going to have to do some tweaking to apache’s conf file so that it will work behind Nginx.

Open up your /etc/apache2/ports.conf file

sudo nano /etc/apache2/ports.conf

We need to change Apache from port 80 to 8080 as Nginx will be server content to the real world via port 80.

Listen 8080

Next we are going to turn KeepAlives off on Apache since Nginx will be dealing with all of the actual browser connections. This will ensure that all of the child processes in Apache die quickly and don’t hang around chewing up memory

Find the KeepAlive entry in your /etc/apache2/apache2.conf file and set it to off

KeepAlive Off

Now that we have made the needed changes in apache we need to restart it so that they take effect.

sudo /etc/init.d/apache2 restart

Next we are going to install Nginx which is a powerful and extremely lightweight http server that is perfect for reverse proxying or load balancing to backend servers like Apache.

sudo apt-get update | sudo apt-get install nginx

Once nginx is installed we are going to need to modify it’s config file located at /etc/nginx/nginx.conf

sudo nano /etc/nginx/nginx.conf

Your conf file should look like this.

user www-data;
worker_processes  2;
 
error_log  /var/log/nginx/error.log;
pid        /var/run/nginx.pid;
 
events {
	worker_connections  1024;
}
 
http {
	include       /etc/nginx/mime.types;
	default_type  application/octet-stream;
	access_log  /var/log/nginx/access.log;
	sendfile        on;
	tcp_nopush     on;
	keepalive_timeout  3;
	tcp_nodelay        on;
	gzip  on;
	include /etc/nginx/sites-enabled/*;
}

Now we need to move on to the actual site config file for our Nginx setup

sudo nano /etc/nginx/sites-available/default

Your file should look something like this (replace domain.com of course)

server {
        listen   80;
        server_name  domain.com www.domain.com;
        error_log   /var/log/nginx/domain.com.error.log;
        access_log  /var/log/nginx/domain.com.access.log;
 
# Main location (path to you blog, relative to your domain root)
        location / {
            proxy_pass         http://127.0.0.1:8080/;
            proxy_redirect     off;
 
            proxy_set_header   Host             $http_host;
            proxy_set_header   X-Real-IP        $remote_addr;
            proxy_set_header   X-Forwarded-For  $proxy_add_x_forwarded_for;
 
            client_max_body_size       10m;
            client_body_buffer_size    128k;
 
            proxy_connect_timeout      90;
            proxy_send_timeout         90;
            proxy_read_timeout         90;
 
            proxy_buffer_size          4k;
            proxy_buffers              4 32k;
            proxy_busy_buffers_size    64k;
            proxy_temp_file_write_size 64k;
        }
 
    # Static files location
        location ~* ^.+\.(htm|html|jpg|jpeg|gif|png|ico|css|zip|tgz|gz|rar|bz2|doc|xls|exe|pdf|ppt|txt|tar|mid|midi|wav|bmp|rtf|js)$ {
            root   /;
        }
	# if the requested file exists, return it immediately
	if (-f $request_filename) {
	break;
	}
 
	set $supercache_file '';
	set $supercache_uri $request_uri;
 
	if ($request_method = POST) {
	set $supercache_uri '';
	}
 
	# Using pretty permalinks, so bypass the cache for any query string
	if ($query_string) {
	set $supercache_uri '';
	}
 
	if ($http_cookie ~* "comment_author_|wordpress|wp-postpass_" ) {
	set $supercache_uri '';
	}
 
	# if we haven't bypassed the cache, specify our supercache file
	if ($supercache_uri ~ ^(.+)$) {
	set $supercache_file /wp-content/cache/supercache/$http_host/$1index.html;
	}
 
	# only rewrite to the supercache file if it actually exists
	if (-f $document_root$supercache_file) {
	rewrite ^(.*)$ $supercache_file break;
	}
}

The above (especially the if statements) help Ngnix pass the static html files that are created by WP Super Cache directly to the users thus freeing up Apache to do nothing more than handle the dynamic requests.

Now it’s time to restart Ngnix and get the whole ball of wax working

/etc/init.d/nginx restart

What we have essentially done is taken the load of serving static files like images, css, and js files off of apache and passed it on to Ngnix which runs a lot faster and leaner than apache for serving static content. All requests for any dynamic content like php still gets passed on to apache. Clean and simple.

In closing let me mention that this is just what works for me, i’m sure that there might be a better way to use WP Super Cache and Ngnix to speed up WordPress, but what you see above has really helped with the load on both of the tech.nocr.at front-end web servers.

Ubuntu Tweaks

Frank — Thu, 07 Feb 2008 02:57:11 +0000

HowtoForge has a great guide on installing and using the Ubuntu Tweak utility.

â€œUbuntu Tweak is a tool that lets you change hidden Ubuntu settings, for example: hide or change the splash screen, show or hide the Computer, Home, Trash, and Network icons, change Metacity, Nautilus, power management, and security settings, etcâ€

It only works on Gnome desktops, but its a really easy way to customize your splash screen, desktop, and hibernation settings. The tweaks are virtually endless.

A basic server for under $100

Frank — Tue, 30 Nov 1999 00:00:00 +0000

If your looking for a second computer to run some basic tasks around the house like a small web server or a file server and don’t want to hack your way into a Slug box then look no further than this compact system from Data Evolution Corporation.

The decTOP computer system comes with 128MB of RAM, a 10GB hard drive (both of which are upgradeable), and is powered by a 333MHz AMD processor. If your looking for a rendering machine or cluster node this isn’t for you but it’s more than powerful enough to run a firewall appliance or a file server for the home. It’s got built in VGA, Ethernet, USB, and even has audio.

This bad boy comes without an OS on it but this simple tutorial shows you how to slap Ubuntu on it. Best of all, you can pick this puppy up for $99

26.25 Gigaflop Super Computer – $1256

Frank — Tue, 30 Nov 1999 00:00:00 +0000

I always feel the need to speed up the process of backup my my dvd’s and encoding them with DVD:RIP, I’m sure this bad boy would make it fly. Calvin College student Tim Brom built, from scratch, a 26.25 gigaflop supercomputer that runs off of a single wall outlet for about $1200. The supercomputer, called Microwolf, has 4 microATX motherboards, each with a dual core CPU and 2 gigs of ram, all connected with an 8-port gigabit switch. The entire thing also includes a DVD drive and a 250 gb hard drive, and runs Ubuntu.

Unfortunately the unit isn’t for sale, but if you want to build your own, there’s a complete write up on his website.
