How to Start Cinnamon desktop from Run Level Three on Fedora 16

Fedora 16

The default UI on Gnome 3 is Bad.  Everyone knows it.  I’ve been running Fedora 14 for what seems like years, hoping that one day the Gnome development team pulls their heads out of their collective asses and restores a simple, low impact interface.  Instead, as of Fedora 16,  I still see these gigantic window title bars, huge ugly icons, lack of minimize and maximize buttons.  What’s next?  Tiles?  Honestly it looks like Gnome 3 was designed for a cell phone.  Or maybe on a cell phone.

Luckily the folks at Mint Linux have been working on a Gnome 3 variant with a sane UI.  One that look like a traditional, but stylish desktop.  I installed Fedora 16 and tried Cinnamon.  While Gnome 2 on Fedora 14 is still more refined, I really like the direction this project is headed.  One problem that vexed me is how to start Cinnamon from run level 3(terminal).

Purpose of this post:

  1. Install cinnamon
  2. create .xinitrc for startx to work

Fedora 13 mount Error Solved

I recently upgraded to Fedora 13(and was quite pleased) only to discover my backup SATA drive would not mount.  I got the generic, ‘mount: /dev/sdb1 already mounted or /home/matt/backup busy’ error message.  Hours of googling and one reinstall later I solved the problem.

Goals of this Post:

– Fix SATA drive mount error: mount: /dev/sdb1 already mounted or /home/matt/backup busy

How to Install Windows 7 over a Network using Linux – PXE, DNSMasq, and Samba

As the age of the netbook arises; the ability to provision Operating Systems over the network becomes highly useful.  More and more these days, it’s less common to see CD/DVD ROM drives in laptops.  In my particular situation my laptop DVD-ROM drive failed.  This prompted me to embark on journey of sleepless nights, sifting through bad information and countless hours of ‘trial & error’ troubleshooting to make Windows 7 install from PXE boot server.

When I first started this project I had no idea what I was getting into or how difficult and poorly documented the PXE remote installation process is.  I imagined that I would use some kind RAM disk to load an ISO image of a Windows CD.  However, the process to boot an ISO image varies greatly between Operating Systems and Windows versions. So if you plan to install Windows XP or Linux using this tutorial…  you will fail.  This Tutorial is step by step for installing Windows 7(only) from a Fedora 10 provisioning server.  This tutorial assumes you have basic Linux, Windows, and Networking knowledge.

Goals of this post:

– Configure Linux Provisioning Server
– Prepare installation media and installation files
– Boot from PXE to Windows PE 2.0
– Install Windows 7 over Network

How to setup automatic Polycom provisioning for the Asterisk 2.0 GUI

Recently we covered the installation of Asterisk 1.6 + Asterisk GUI 2.0.  In this article we will talk about the details necessary to enable Polycom provisioning from the ‘Users’ tab of the Asterisk 2.0 GUI.  By default auto-provisioning will not work out of the box.  You would think when the GUI is installed that it would be setup as well, considering that you have the option to enter a MAC address in the user extension creation process.

Nor are their docs related to configuring this in the source packages(that I could find).  Online forums and tutorials were of no help either.  There are many post online claiming that you need to set up DHCP, ‘option 66’ for Polycom provisioning to work.  This is true of TFTP provisioning from AA50 appliance, but not from the Asterisk 2.0 GUI that relies solely on HTTP.  At least as far as I can tell.

I think Digium is being vague on purpose about this because they do not want to undermine their Asterisk Appliance product.  While I understand this line of thinking, it’s not consistent with the Open Source business models that have succeeded.

Open Source depends on reaching vast amounts of people due to the low cost.  When my customers have to choose between a Avaya system(running Linux) that cost $45,000 /w phones or a Asterisk system w/ Polycom phones for $19,000; it makes the lesser known Asterisk product attractive.  Over time the base builds up and Digium collects on hardware and support fee’s.

So from my perspective, any Asterisk installation helps Digium’s bottom line eventually.  Even if Digium doesn’t see money from every Asterisk user, simply the presence of those users makes Asterisk a more credible product.  Bringing more and more Enterprise and Government contracts to everyone, thus more money and investment into Digium.

Alright my tirade is over, back to business!  This post assumes you have installed a recent version of Linux, Asterisk 1.6 and the Asterisk 2.0 GUI installed.  If you do not, read my post:How to setup the Asterisk 2.0 GUI with Asterisk 1.6.

The Goals of this Post:

-configure phoneprov for Asterisk 2.0 GUI

Ventrilo Linux Client in Fifth Year of Development

I play World of Warcraft on Linux all the time.  I boot into Windows XP for Arena and extended play, but all my causual gaming is on my work computer – that runs Linux.  So for this reason I’ve had an interest in the upcoming Ventrilo Linux client for a long time. A very long time.

Since 2005 when they first announced that the client version for Linux was on it’s way I’ve been excited!  Imagine the Linux Desktop getting support from the industry leader in VoIP group communications!  Unbuntu/Fedora Linux will benifit greatly by making it possible for more Linux gamers to communicate with fellow online gamers of any platform.  The only problem is that the Linux client was never released.  Or at least, not yet.

Adjust date & time (NTP) on Fedora Linux

Correct time is crucial for many Network services.  Time stamps are required for accurate logs, email, and in the case of Asterisk – voicemail.  A customer sent me a request for instructions on adjusting date & time for their Asterisk PBX.  Most Fedora based systems come with a tool just for this purpose.  From the Desktop open a console window and type:

Disable automatic offline mode in Firefox

If you use wireless with Fedora or Ubuntu then you problably encountered the annoying, “OFFLINE mode – Firefox is currently in offline mode and can’t browse the Web” page.  You start your web browser after selecting the access point you want and that obnoxious message appears.  So I’m writing this post to remind myself how to fix it without twenty minutes of googling.  Basically Firefox by default checks to see if you have a network connection via the Linux Network Manager applet.  This works fine under normal cicumstances, but I prefer init scripts to start my ethernet interfaces.  Even though you may be connected to the LAN, Firefox doesnt know.

SOLVED: ProFTP will not start after install on Fedora 11

I was working on a project for VoiceIP Solutions yesterday and I required a FTP server to provision some Polycom Soundpoint IP phones. So I did my usual ‘yum install proftpd’ , followed by ‘service proftpd start’, but the service failed to start. So after some poking around – checking user assignment for that process and permissions I found nothing. So I decided to invoke the server from the command line with the ‘-t’ to check for errors:

[root@mattcom1 log]# proftpd -t
Checking syntax of configuration file
– warning: unable to determine IP address of ‘mattcom1’
– error: no valid servers configured
– Fatal: error processing configuration file ‘/etc/proftpd.conf’

The error told me right away that the issue was my ‘/etc/hosts’ file. My server name ‘mattcom1’ was not found in that file. Even though both the Network manager and Network configuration tools showed a hostname, there was actually nothing added to the ‘/etc/hosts’ file. watch out for this one!

Tweaking Linux and WINE for World of Warcraft

It’s great that the World of Warcraft runs well on recent editions of WINE(Unbuntu/Fedora), but even when using OpenGL the typical Linux user can expect a frame rate reduction from 15%-30% over Windows XP.  However, I must point out that there are many reports of frame rate drops in Windows Vista and Presumably Windows 7(because of virtualization of XP apps).

All this is okay for typical grinding, leveling, and five man instances.  That said,  my GeForce 7950 GTX is only cranking out 30 FPS in low populated zones…  So for the bigger raids, PVP, and highly populated zones like Dalaran it can be frustrating trying to pwn at 12-16 FPS.  In fact my mission is to get at least 40 fps with the graphics card I have.

I was able to improve my frame rate by disabling mods like ‘Questhelper’ in battle grounds.  I added additional RAM to my system.  Although the frame rate boost was negligible; loading times were cut in half. (more…)

Microsoft and Novell bring Silverlight to Linux

I recently visited a local radio station kirotv.com(to hear the Mariners game) and the web site required Microsoft Silverlight to be installed for streaming audio.  It also noted that Silverlight was available for Apple OS X, Windows, and Linux.  Say that again?  Microsoft making multi-platform software?  Giving customers choice?  It sounds crazy, but it’s absolutely true.  Sorta, they are releasing the Linux version via an ‘Agreement not sue’ for downstream Novell customers.

The project is called, ‘Moonlight’.  When I went to download Silverlight from Microsofts website I was redirected to the Moonlight front page.  Moonlight is a part of the mono project.  The mono project is the Open Source version of ‘Active X’ sponored by Novell.  Microsoft has a sizable investment and co-marketing agreement with Novell, of whom is the distributor of SUSE Linux.

What is stange is that Microsoft doesn’t give an explicit agreement or license to use it’s ‘silverlight’ technology, instead it posted a covenant not to sue customers of Novell.  I’m not a lawyer but this seems odd to me.  Not to mention, that nobody really uses SUSE or Novell Linux; at least in terms of users and worker bee’s.
