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:

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.

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…)

SOLVED: Real Player 11 Gold, ‘no sound’ issue with Fedora/Unbuntu

I like Real Player.  I like Real Networks too.  They use and support open source software.  They haven’t made the GPL leap yet, but at least Linux has a decent streaming media player because of them.  I was happy until a recent upgrade.

I was stumped on this one for a while.  I updated from Real Player 10 to 11 and then got no sound.  I uninstalled and tried the Real .bin package.  Same problem.  So I downgraded to Real Player 10, but again no sound(even though the player appears to be playing without error).

What made it worse was how lousy the support forum for Real Player on Linux is.  I mean it really sux.  The web design and support layout is okay, but there are no real answers to many of the post I looked at.  It was frustrating because there are many, many people experiencing the same problem.  I understand it’s free, but did anyone test it on Unbuntu and Fedora with different audio servers before release?  Right now, Unbuntu and Fedora use, PulseAudio, ALSA, and OSS.  Many times all of them at once, as to offer the most driver and application support.  Big oversight.

I tried OSS drivers with the same result:

How to make USB and DVD ROM drives work on Fedora 10

Lately, I’ve been working on Asterisk PBX related articles, but today we’re going to tackle a common problem with Fedora 10: getting drives to mount to the Desktop.  If you are experiencing trouble, the likely cause is that your current user, does not have permissions to access that hardware.  The reason for this has a lot to do with the security model of Linux.

In the old days computers came on large mainframes.  It was not practical for engineers and scientist to have their very own main frame, so Unix was designed to be a multi-user operating system.  Everyone connected their own keyboard & monitor.  The permission structure was set so only certain individual accounts could do certain things.  Like say, reboot a system or delete a database.

By contrast Microsoft Windows(thru XP) is a single user operating system.  In Windows you can create extra accounts, but any of those accounts can execute arbitrary code from anywhere in the file system (c:\\ drive).  Which is a big reason for the many attacks on Windows systems.

Recently my friend got a virus that made XP unbootable and stole his World of Warcraft account login and password.  The hacker then used that information to login to his account, change his password, and his accounts valid email address.  The hacker then sold all his gear and used his character to scam other people in bad trades.  The account became banned for “economic extortion” before my friend could get his Windows XP machine back up and running.  Now he runs WoW on WINE/Fedora 10.

An appeal to Blizzard got his account back after several days and many emails. My friend requested that they check the IP address of the hacker and compare that to his previous logins.  What if the virus had collected his bank account credentials instead?  In a way he got lucky.

– correct authorizations in Fedora 10 and allow access to USB and DVD – ROM devices

It seems odd that someone would be unable to access a USB thumb drive on any modern desktop computer, but Red Hat the maker of Fedora Linux is far more interested in their commercial offering, Red Hat Enterprise Linux(RHEL).  They model RHEL development on previous versions of Fedora.  So desktop integration is obviously not their top priority; stability and security is.  This neglect has allowed rival Unbuntu Linux to come in and snatch up the Linux desktop market.  Big mistake Red Hat…  however with a little work we can make Fedora 10 desktop work well without them.

So to correct the permissions issue(from Gnome) start by clicking, System –> Preferences –> System –> Authorizations.  Fedora may ask you for your ‘root’ password.

Set access to allow anyone to mount and unmount USB and other devices!  I hope this helps.  It’s frustrating dealing with these little things, but hey, “it’s free”!  If it doesn’t take, leave a comment below and I’ll try to help.
