Ubuntu Unleashed

I just ran into another Virtualization solution called Qemulator, it is a full featured emulation suite for the qemu virtual engine, written in python GTK/Glade2. I have not had the chance, time yet to test it out, but by the looks of the screenshots, it may be better than Vmware, please let me know what you think if you have tried this before I have.

Qemulator provides an easy and fast to use image and device management, a "My machines" list and interactive job control.

It comes with a list of all running jobs from where you can open the contol panel for each job and performing on demand action. Full interaction for mounted volumes, usb devices, keyboard and mouse interaction, screenshots, wave capture and save/restore machine state and open vnc viewer is provided.

The project is still under development. Current version should run stable on most Linux machines providing allmost all functions of qemu, but there are still some works to do.

Qemulator comes with its own easy to use graphical installer.

Qemu 0.8 - 0.9 compatible
- Changed filesystem and boot logic to a more simple and clear context
- Many new qemu options found their way to the gui
- Many functions are enhanced by image autodetection
- Added new guided dialogs to add new machines and to install new systems
- Creating of new images now includes all common qemu-img options
- Implemented Exporting of a VM configuration as shellscript
- New translations: Catalan, Slovenian
- Many bugs fixed (see buglist)
For full list of changes read the release notes on project home or distributed with the package

I am a big fan of motorola and Nokia, here is a simple how to to get your motorola connected through Ubuntu.

Luckily the phone, once connected by the supplied USB cable, is automatically recognized by Feisty (Ubuntu 7.04) and the proper kernel modules and devices are loaded. All that remain is for you to run gnome-ppp as root, configure the connection and enjoy.
If you don't have gnome-ppp just install it using Synaptic or apt-get.

Open gnome-ppp as root by either creatinga desktop launcher with "gksudo gnome-ppp" as the command line or typing that into the command line your self.
Enter credentials ISP@CINGLARGPRS.COM for the username
CINGULAR1 as the password
*99# as the phone number.
Click setup
Click detect to auto detect your modem (it shoudl find it as ttyACM0)
Click init string andmakemake the following changes:
Init 2 should read: ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Init 3 should read: AT+CGDCONT=1,"IP","isp.cingular"
Close "setup" and click on connect. After a sort pause at "Waiting for prompt" it should connect you.

Software
Make sure you are running the latest versions of firmware for the Treo 650. I happen to have an unlocked edition so this is very easy to fix from PalmOne. I recommend going with the latest but this isnt a deal breaker. I am going to assume this from a total newbie position as yes, you can use pppd or wvdial from CLI. For our test we will be using Ubuntu 6.06 and Gnome-ppp. To enable “tethered” mode on the Treo you maybe lucky and dial #*83843733. I was unable with GSM and Cingular and instead used this software which works wonderfully. If anything they also officially support Linux.

http://mobile-stream.com/usbmodem.html

Hardware
The hotsync USB cable will be all that is needed. I have problems in the past plugging into an external USB hub so keep that in mind.

Installing Software
I downloaded the USB Treo program and explored the zip file. I extracted the PRC to a SD-Card

PALM\LAUNCHERS

apt-get install gnome-ppp

sudo vi /etc/ppp/options

Here is a quick easy & efficent way to syncronize your ipod with Ubuntu.

Prerequisites

I found yet another blazing fast Infodomestic Objects application made just for Ubuntu Feisty, its Xchat, we all know what that is right? Its an IRC client for Ubuntu but prelinked with Infodomestic Objects so you can run it without installing the dependencies, this means you can run xchat without installing it, Xchat also loads faster and runs more smoothly.
Download Here

Wow, I just found a truly unique application that runs fast as hell right from memory and does not require root access to install, so you non-root users can download this single file and you dont have to install a thing, it runs straight from ram and /tmp and believe it or not, it is faster than firefox and swiftfox because it is all pre-linked. No compiling, installing or anything is necessary.

"ioSwiftFox is a recompilation of Firefox 2 for Infodomestic Objects Linux. It is developed and tested under Ubuntu Linux, and can be run with just one click without installation on your system."
ioSwiftfox is secure as well, since it runs in ram, so you dont have to worrie about people sn00ping your browser history. This also auto loads your extentions in your current swiftfox/firefox directory if you do happen to have it installed.
Howto:
Download here
chmod +x ioSwiftFox2.0.0.6-pentium4_Infodomestic0.8.5
mv ioSwiftFox2.0.0.6-pentium4_Infodomestic0.8.5 ioswiftfox
./ioswiftfox

Heron (Ubuntu 8.04), the next version of Ubuntu that will succeed Gutsy Gibbon (Ubuntu 7.10, due for release in October 2007). Not only will the Ubuntu community continue to do what it does best, produce an easy-to-use, reliable, and fun free software platform, but this release will proudly wear the badge of Long Term Support (LTS) and be supported with security updates for five years on the server and three years on the desktop. I am hoping to see Ubuntu in every school in the United States.

We Can all make this possible by sharing our knowledge & compassion to our friends, families, co-workers and the community. The LoCo project is here to help groups of Ubuntu fans and enthusiasts work together in regional teams to help advocate, promote, translate, develop and otherwise improve Ubuntu. Our worldwide network of LoCo teams is providing a strong backbone to our already vast and extensive Ubuntu community. Why not go and see the full list of teams!

Ever since the birth of computers, enthusiasts and fans around the world have collected together in garages, universities and pubs to talk about their interest, learn from each other and help promote their interest. Combine this with the huge popularity of Ubuntu, and you have the Ubuntu LoCo project. So lets continue this history and share what we love, and the benifits we have to offer Ubuntu as well as what Ubuntu has to offer us as a community & world we live in.

• I want to JOIN a LoCo team! - To join a LoCo team, take a look at the Joining page and get in touch with the contact of the team you want to join.

• I want to START a LoCo team! - To start a team, or contribute to one, read the LoCo Team HOWTO!

Most people only ever see the end-user view of Ubuntu, running it on their desktops, servers and mobile devices around the world. For these users, Ubuntu provides a simple, convenient means to do what they want to do easily, effectively and without unnecessary complexity. For many of us though, we want to open up the hood and understand how the system works and how to extend and grow it. Thousands of us get out of bed every day, united behind Ubuntu, ready to make a difference, working together to make our vision happen.

One of the great things about the Ubuntu Community is that you are able to Invent applications and features for the next Ubuntu Release via Ubuntu BluePrints, with the communities knowledge and compassion we are able to make each Ubuntu Release better than ever with more features that are needed most. I strongly recommend Ubuntu BluePrints for the simple fact that just with one Idea may be able to see it in the Main Releases of Ubuntu. Why not share your knowledge compassion and troubles you are having with ideas to improve Ubuntu?

Share your ideas, and let Ubuntu Grow within us and the community here

Feel free to comment telling me what you think, also if you have something I can add to my collection let me know!

okay in one of my nights searching the internet and ubuntu forums i came a cross a nice tweak for Ubuntu. It involves messing with your etc/hosts file in order to block web sites that produce ads. Cool eh? Here is how:

1. back up your original host file located at etc/hosts
sudo cp /etc/hosts /etc/hosts.old

2. Download a good/updated host file here

3. Open your hosts file
sudo gedit /etc/hosts

4. Paste the contents of the downloaded hosts file (from mvps) into the bottom of the /etc/hosts - do not override any content!

5. Test it out, try loading one of the sites in your browser. You should get a 404 error message.

To take this even further you can use a hosts file update script located here

Follow these steps
1. Download the file at http://hostsfile.mine.nu/downloads/updatehosts.sh.txt

2. Rename updatehosts.sh.txt to updatehosts.sh

3. Make the file executable by doing using the follow command
chmod a+x updatehosts.sh

4. Install tofrodos
sudo apt-get install tofrodos

5. Run the update
sudo ./updatehosts.sh
This tweak has been tested and seems to work 100% on Ubuntu FF - no guarantees

Found a little script that will convert videos to IPod video format (i.e. mp4 with xvid and aac encoding) utilising ffmpeg and ruby. The nice thing about this is that it will preserve the original aspect ratio and add black bars depending, so videos look like they should do (well aside from being in QVGA 320x240 resolution!). Some smartphones (such as the Nokia N95) are also able to display this format =)

The script can be found here

For a little HOWTO:

Open up synaptic and ensure that you have ffmpeg and ruby installed/
apt-get install ruby ffmpeg liblame-dev libxvidcore4-dev libx264-dev libfaac-dev libfaad2-dev
sudo apt-get build-dep ffmpeg
Download the script:

I constantly upgrade my kernel and constantly keep applications updated, I have been reading many sites proclaiming that CFS patchset "The Completely Fair Scheduler" from Ingo Molnar is better and faster than Con Kolivas 2.6.22-ck1 patchset
I am extremely dissapointed in all the hype and the news that cfs will be a part of kernel 2.6.23...
Here is what I noticed about cfs which sucks...
Boot time:5 seconds longer than ck patch
Nautilus: Takes a second longer to load up... wtf
Firefox: takes 2 more seconds to load, simple web pages like digg and my site spike to 100 cpu usage and mouse freezes..
Music: Choppy with more cpu usage
Video: glxgears reported a loss of over 100 fps
Overall CFS sucks, and ck's patchset kicks ass, I have ck's patchset installed with the latest ubuntu feisty kernel as well as the "The Completely Slow Scheduler CFS"

I would love to see some benchmarks of how cfs is faster than CK and what it actually improves. Also I cannot believe Linus is implementing this POS Patchset..

This is a true dissapointment for the Linux Community, I now understand why Con Kolivas quit because there is so many ignorant people out there that dont respect a good coders work. Ck's patchset is way faster than CFS, CFS is garbage and im only keeping it on my pc to do benchmarks when requested.

Be smart get Con Kolivas Patchset here and do you and the Linux community a favor and actually try out CFS and let me know what you experience

Here are my benchmark results with hardinfo:
cK patchset
cfs the slow scheduler

I have been using this little applet called cryptkeeper with encfs for a while now, it is a beautifully simple power user application that will help you keep your private information safe and secure.
Basically Cryptkeeper is a Linux system tray applet that manages EncFS encrypted folders. In this simple Howto, I will assist you in installing encfs and CryptKeeper.

1. Install encfs like this:
sudo apt-get install encfs
sudo echo fuse >> /etc/modules
sudo modprobe fuse
sudo addgroup fuse
2. Then you must log off and back on again.
To do this quickly just press ctrl+alt+backspace and log back in.
Then Download & Install Cryptkeeper via Getdeb.net here
or wget http://www.getdeb.net/download.php?release=1177&fpos=0
Then click Applications->system tools->Cryptkeeper or alt F2 type in Cryptkeeper.

I personally like cryptkeeper to Autostart, if you want to do this press alt+F2 type/paste gnome-session-properties and add "cryptkeeper" without the quotes to start it up automatically
-- I personally am the administrator where I use this so I like to run cryptkeeper as root via gksudo as an added form of protection, you decide.

I just ran accross a nice site www.go2linux.org the admin left a nice comment about my layout and content, thankyou.. while browsing his site I found some great content on 25 usefull linux commands I definately use daily, the author added 7 of his favorites
Check it out here
Id like to add a few commands I use as well.

htop: nice looking top for process and memory stats.
id: to check which user groups you belong to
whoami: check which user you are in a multi-user environment
echo;
example: echo * in your current directory to show you files if somehow you deleted ls - lol
example: echo whatever >>/etc/network/interfaces
cat: I like cat because I paste scripts and code right into the terminal like this:
cat >>file
type stuff/paste stuff here
cat file
root@ion:~# cat file
type stuff/paste stuff here
root@ion:~#

My Ubuntu Box was running slower than I thought I could tweak it, so what I did was look for some good patchsets and I seen some conflicting results with cfs and ck and decided to test a few benchmarks and the ck patchset is a little more responsive than cfs on my system. I have supplied a link @ the end of this post with statistics and discussions about cK vs cfs.

Here is a guide for you to walk you through the patching/compiling process, I hope you like it!


*Warning*
If you have truecrypt installed or any kernel modules like the rt73 usb wifi driver, it must be recomiled/installed for the new kernel, the performance is worth the time and effort. Make sure you download anything you need to recompile driver wise before you reboot to the new kernel.

*The drivers must be recompiled while using the new kernel!

This How-To will guide you through the compilation/installation of the 2.6.22 (more recent than the one distribuited with Ubuntu Feisty 7.04) with the performance patchset by Con Kolivas.

1-Download what is needed

Type in the command line:

I was just searching google for some BlackHat pdf's and ran accross a great firefox extention that works with tor. Here are some of the features..

This is a c/p right from the developers site:
Download/install here

About

Torbutton is a 1-click way for Firefox users to enable or disable the browser's use of Tor. It adds a panel to the statusbar that says "Tor Enabled" (in green) or "Tor Disabled" (in red). The user may click on the panel to toggle the status. If the user (or some other extension) changes the proxy settings, the change is automatically reflected in the statusbar.

Some users may prefer a toolbar button instead of a statusbar panel. Such a button is included, and one adds it to the toolbar by right-clicking on the desired toolbar, selecting "Customize...", and then dragging the Torbutton icon onto the toolbar. There is an option in the preferences to hide the statusbar panel (Tools->Extensions, select Torbutton, and click on Preferences).

Newer Firefoxes have the ability to send DNS resolves through the socks proxy, and Torbutton will make use of this feature if it is available in your version of Firefox.

Description of Options

The development branch of Torbutton adds several new security features to protect your anonymity from all the major threats the author is aware of. The defaults should be fine for most people, but in case you are the tweaker type, or if you prefer to try to outsource some options to more flexible extensions, here is the complete list. (In an ideal world, these descriptions should all be tooltips in the extension itself, but Firefox bugs 45375 and 218223 currently prevent this).

• Disable plugins on Tor Usage (crucial)
This option is key to Tor security. Plugins perform their own networking independent of the browser, and many plugins only partially obey even their own proxy settings.
• Isolate Dynamic Content to Tor State (crucial)
Another crucial option, this setting causes the plugin to disable Javascript on tabs that are loaded during a Tor state different than the current one, to prevent delayed fetches of injected URLs that contain unique identifiers, and to kill meta-refresh tags. It also enables an nsIContentPolicy that prevents all fetches from tabs loaded with an opposite Tor state. This Content Policy serves to block non-Javascript dynamic content such as CSS popups.
• Hook Dangerous Javascript (crucial)
This setting enables the
