How to disable NMI watchdog?
by Subhas Sing 08 Jan '13

08 Jan '13

Hello, I am trying to install vmware server in Fedora 16. I tried to disable NMI watchdog kernel parameter. Can anybody please let me know how do it ? I followed following procedure but without success!! $ cat /proc/sys/kernel/nmi_watchdog If you get a '1', then the feature is enabled and must be turned off or VMs will mysteriously crash. To turn off nmi_watchdog is different for Fedora 15 and Fedora 16: [5] Fedora 15: Edit /boot/grub/grub.conf and add “nmi_watchdog=0” to the kernel line.[5] Fedora 16: Edit /etc/default/grub and add “nmi_watchdog=0” to the GRUB_CMDLINE_LINUX. Then run: # grub2-mkconfig -o /boot/grub2/grub.cfg” to rebuild the grub configuration. Now, reboot the system and check the /proc/sys/kernel/nmi_watchdog parameter again to make sure you see a '0'. http://communities.vmware.com/message/1891427 Thanks,Subhas

Oh no! Something corrupted in /proc
by Neal Becker 08 Jan '13

This is (up till now) extremely stable f17 x86_64 server. Now running ps aux will hang forever. I traced it to: ls /proc/18103 [ hang forever ... ] I see NO messages in /var/log/messages that could be relevant. This is uname -r 3.6.3-1.fc17.x86_64

OT - wire tester
by Robert Moskowitz 07 Jan '13

07 Jan '13

My brother-in-law just called for help; his Test-um TP600 (discontinued) just died. It has suited his needs to a tee but now he needs something new. Something with similar functionality and cost. He said I recommended this to him some eons ago when I was informed about test equipment. I haven't done that stuff for years. So are there any recommendations on what others use? thanks.

heads up xhost username on F17 -- manpage bug, I guess
by Joel Rees 07 Jan '13

07 Jan '13

A heads up notice: xhost user gives xhost: bad hostname "user" but, sudo -u user ls /home/user lists the user's home directory. So the username is valid. Searched the web and found an ancient thread on xhost on Ubuntu (see <https://bugs.launchpad.net/ubuntu/+source/x11-xserver-utils/+bug/60040>), and it suggested xhost SI:localuser:user which does what I wanted. This is a change since F16, and not mentioned in the manpage. (The manpage, kind of looks like someone started to bring it up to date and forgot it in the middle.) I'd check to see if there is a bug filed, but all the fussing with the upgrade that ate my winter break leaves me running way behind. No time. (And not a lot of motivation, frankly.) -- Joel Rees

K3B crashes on opening wma audio
by Robert Moskowitz 07 Jan '13

07 Jan '13

I am trying to burn a wma audio file to an audio CD. So I tried k3b. It crashed on trying to open the wma. So I tried to play the file with movie player, which told me it did not have the files to play wma and I allowed it to download the needed files. After restarting movie player it played the wma audio. I then tried k3b again, and it still crashes. Nothing in /var/log/messages. Any recommendations?

I am trying to install f17 from my local repos using the netinstall CD. But it is trying to access the internet repos. How do I stop this? I know there is some boot option but so far I have not found it yet...

bluetooth connection between two computers using pand with Fedora 17: connection failed
by Kevin Wilson 06 Jan '13

06 Jan '13

Hello, I am trying to create a simple bluetooth connection using pand with Fedora 17. I followed these two links: http://bluez.sourceforge.net/contrib/HOWTO-PAN http://ubuntuforums.org/archive/index.php/t-1393215.html And ran, on the server: pand --listen --role=NAP And on the client-side pand --connect btAddressOfServer I see this on the client side: ... Connecting to 00:23:4E:E5:70:3A Bluetooth: Unexpected continuation frame (len 0) Bluetooth: Unexpected continuation frame (len 0) bluetoothd[602]: input-headset driver probe failed for device 00:23:4E:E5:70:3A input-headset driver probe failed for device 00:23:4E:E5:70:3A Connect to 00:23:4E:E5:70:3A failed. Operation now in progress(115) ... I also activated hcidump and it did not show something which might be considered as an error. Did anybody tried it and it worked for him ? Any ideas what can be the problem? When I try to switch sides I get the same problem. I use fedora 17 with these rpms: bluez-4.99-2.fc17.x86_64 bluez-compat-4.99-2.fc17.x86_64 rgs Kevin

VirtualBox: After restoring fc17 NetworkManager cannot enable p2p1 automatically
by Dan Woizek 06 Jan '13

06 Jan '13

Hi, my solution or workaround is: Before saving the machine state of fc17 guest I have to deselect "Enable networking" to shut it down. After restoring the machine I can enable the network correctly. This works for me! Have a nice day without Linux problems! :-)

If you like sports you might hit on your local station to broadcast Oz footie in HD. In North America, CBS has, for some years, broadcast (OTA) what appears to be a completely uncompressed HD stream and watching football ( American style) in that format is awesome. As a 'benchmark' most HD programs hereabouts take 5 to 6 G/hour for storage. Some programs (The Good Wife is one example) regularly takes 8G/hr and the difference is noticeable. I get that program OTA from 2 different stations: one at 8G and one at 5G. The difference is noticeable. NFL football runs 11-12G/hr in 720p. G
