Resample MP3’s for Polycom Ringtones with Audacity

A customer of VoiceIP Solutions sent me this useful tutorial for re-sampling Polycom Ringtones.   If you have an MP3 you like, it can be re-sampled for use with a Polycom IP SIP phone!  The procedure is pretty straight forward, Install Audacity with yum or your favorite package manager, re-sample the track, then edit the proper Polycom Soundpoint boot files.

Goals of this Post:

– Install Audacity Digital Audio Editor
– Convert a MP3 to Polycom compatible track
– Enable custom special Ringtone on Polycom Soundpoint IP SIP phone

ATI 4870 + Fedora 10 + 9.10 Catalyst drivers = World of Warcraft on Linux!!!!

Just an update to my previous article, ripping ATI for their lame Linux support – I finally got World of Warcraft working on Fedora 10, ATI 4870 graphics card, Catalyst 9.10 drivers!  All it took was down grading from Fedora 11 to Fedora 10, turning off my open GL desktop and waiting 6 months for four driver releases from ATI.  That’s all it took to run a game that works great on Linux… if you bought an NVIDIA card!

Get rid of that ‘default keyring’ password bullshit when you login to GNOME

I haven’t gone on a good ol’ fashioned rant in a long time.  And you know what?  This one has been in the making for a while.  I’m not holding back… here I go…

Policykit sucks!!!  What’s with this excessive password crap?  By default for GNOME in Fedora 10/11 you have to use a password for everything!  You need a password to login to GNOME, then once inside GNOME your password will be required to unlock network-manager.  That doesn’t seem so bad…  I’ve only entered the same password three times(including the Linux login).

So I have access to the web and I’m happy for the moment until I decide to attach my USB thumb drive to copy some files for my neighbor…  …and guess what?  I need a password to mount my USB thumb drive.  So I decide to watch a TV show I have on a DVD-R.   By default mounting a DVD requires my password.

Installing programs from the ‘Add/Remove Software’ requires your regular keyring password to launch the app and the root password to install the actual software.  Now am I wrong in concluding this is a totally retarded way to handle desktop security?  Typing in the same password eight times in thirty minutes?  This is why 7 year old Windows XP is still a contender.  Even though Open Source GNU Linux is technically superior and far more secure.

Seven times GNOME keyring asked for a password.  That’s as bad as Vista.  No, it’s even worse.  Nobody loves Vista.  In fairness however, Microsoft’s Vista doesn’t require a password to attach a common USB pen drive.  Even using an SSH connection from the console requires keyring to intervene with GNOME!

Luckily, you can install ‘pam_keyring’ with yum.  This will use your Linux login for the default keyring at login, but you have to access the keyring-manager to adjust the rest.  Huge hassle.  It’s annoying shit like this that keeps the average bear off Desktop Linux.  My Mom is a smart woman, but she would never figure this out, and so she will continue to run Windows XP indefintely.

Pick through the options and see if you can find where to grant access to mount a DVD. This is not security, it's insanity.

ATI HD 4870 (catalyst 9.6) fails to load World of Warcraft

I just upgraded to a ATI HD 4870(w/ 1 Gig DDR 5!).  I read some rave reviews about the 4800 series cards and heard via the grapevine that ATI had much improved Linux support.  However, I was disappointed to find out that the catalyst 9.6 driver will not build with Fedora 11’s stock 2.6.29 kernel.  Bummer, I really like Fedora 11.

So I downgraded to Fedora 10 and the ATI driver built without problem.  My next mission was to install WoW, which went fine.  I was able to download and install without error.  But when I start the game I get one of two typical errors:

====================================================

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!

Fedora 11 detects and installs on-board Intel RAID driver correctly

Do you own a Mainboard that has built-in RAID, only offers Windows drivers?  have you always wanted to use the RAID BIOS for managing disks, but only had the Linux MD Soft RAID as option?  Not anymore!  I’m using a INTEL D945 GNT Desktop board with two 160 GB, Serial ATA drives.  I entered the BIOS menu and selected the RAID option.  After a reboot a RAID BIOS menu appeared and I was able to create a RAID 0 array.

Then I booted to Fedora 11 with a Live USB device.  From the Desktop I double clicked on the ‘install to hard drive’ icon.  I was really surprised to see a single 320 GB disk!  I did the install and it booted perfectly!

Now, some naysayers will complain, “It’s still Soft RAID anyways…”.  It’s a crappy point to make, obviously it’s still Soft RAID, but the main difference is the ability to create and manage RAID disks from the BIOS as opposed to using a Linux boot disk or the OS(if you can).  Most consumer grade RAID PCI cards use Soft RAID anyways.

Also lets consider, that in the past it was necessary to have a special RAID controller for performance gains.  But modern SATA boards have the PCI bus and the processing power to make those gains negligible(except compared to very pricey cards).  The real feature most of us want is the ability to access the RAID arrays from the BIOS boot screen.  Thank You Redhat, I’m already really liking fedora 11, I don’t need to throw away $150 on 3Ware SATA RAID cards anymore!  Please post your on-board Linux RAID success stories!

Remote Upgrades on Fedora based Systems

I’m doing a remote upgrade on a test server at work(VoiceIP Solutions). So today’s article will cover upgrading from Fedora 6 to Fedora 10. Before you start, backup any important data! Every once in a while some dependency issue will crop up that blows up your server.  Also upgrading from Fedora 6 to Fedora 11 is not as easy as say, upgrading from Fedora 10 to Fedora 11.  So be careful and upgrade on a regular basis!

The Goals of this Post:

– remote upgrade from Fedora 6 to Fedora 10

Xen Dom0 and Paravirtualized guest reported to work in Fedora 11 Beta

Xen 3.0 Dom0 support reported to be working

Xen 3.0 Dom0 support reported to be working

Great news everyone! Fedora Weekly News, issue 175 reports successful Dom0 integration in Fedora 11 Beta.  Here is the quote I read today:

Pasi Kärkkäinen reports[1] success with a dom0 kernel using Fedora 11 Rawhide. “I’m able to run Xen paravirtual (PV) domUs, install new domUs using virt-install and also install and manage domains with virt-manager.”



The environment used was:



– Fedora 11 (rawhide as of 2009-05-05)
– Xen included in F11, no external patches (xen-3.3.1-11.fc11)
– xen-tip/next pv_ops dom0 kernel as of 2009-05-06, Linux 2.6.30-rc3.
– All the rest was standard stuff included in Fedora 11 as well

This is all coming sooner than I previously expected.  I’ll be following up on this story next week as I compile more information and try it myself.  Paravirtualized Operations provide a significant boost to guest Operating System performance and no project implements it better than Xen.  I’m glad to read that it is working in Fedora 11.
