then i would suggest unplugging all harddrives except the hdd where the os is on. On my server an broken hdd freezed the system (also without ANY trac)

2012-08-20 17:56:11 -0600 answered a question authentication required by wireless

You can try to update F17. i also had connection issues after a fresh install. After an

sudo yum update

it was fixed. I guess updating is hard without working wireless. So you may try to switch to Cable just for updating.

You can also check the output of dmesg if there is any problem with your wifi.

2012-08-20 17:43:46 -0600 answered a question Fedora 17 Install with USB

you should delete all partitions on the usb stick and then rerun the LiveUSB tool. You can use the "Disk Utility" tool for this task.

Just select your usbstick on the left side and then remove all partitions on it.

You can also try this method:

su -c 'dd if=Fedora-16-x86_64-Live-Desktop.iso of=/dev/sd''X'' bs=8M'

But be SURE to replace the X with the correct device path /dev/sdX. You can see the device path in the Disk Utility

2012-08-20 17:33:21 -0600 answered a question Fedora 17 random reboots: where to begin troubleshooting?

you can still try to use netconsole. Which will send kernel message over the network:

#Client
nc -l -u 6666

#Server - will not preserve restart
insmod netconsole netconsole=4444@192.168.178.1/eth0,66..

#Server - will be configured after restart
echo 'options netconsole netconsole=4444@192.168.178.1/eth0,6666@192.168.178.59/e0:49:75:c3:0b:ff' >> /etc/modprobe.d/netconsole.conf

192.168.178.1 = Server IP

192.168.178.59 = Client IP

2012-08-10 18:58:55 -0600 answered a question Conversion from ext4 to gfs2

you could

  1. shrink the ext4 filesystem to the minimum size
  2. then shrink the partition,
  3. create an new gfs2 formated partition
  4. copy all the data from ext4 to gfs2 and then
  5. move the gfs2 to the begin of the hdd.

this will only work if you have < 50% used space.

i don't think file system conversions are possible. As far as i know you can only convert from ext3 -> ext2 (remove jornaling) but these 2 filesystem are related very closly.

EDIT

You can convert ext4 -> btrfs

btrfs-convert
2012-08-10 18:52:11 -0600 commented question Fedora 17 random reboots: where to begin troubleshooting?

does it freeze and you have to reboot it or does it really reboot? I don't think the kernel would force an reboot on an error. I would check the hardware, maybe power supply or overheating?

2012-08-07 18:37:32 -0600 answered a question Restricting users to only games and educational programs

i'm not sure if this would work, i only did some short tests:

every application shortcut in F17 is in

/usr/share/applications/

you can change the ownership of all the file to only your username:

sudo chown root:<yourusename> /usr/share/applications/*
sudo chmod o-r  /usr/share/applications/*

then you have to "whitelist" every entry you want to show them with:

(for example gnome mines game)

sudo chmod o+r /usr/share/applications/gnome-gnomine.desktop

I don't know how old your kids are, but THIS METHOD ONLY HIDES the shortcuts from the Applications menu (Activities -> Application). If you know the name of the programm you can start it anyway.

I don't give ANY guarantees that this won't break your computer!

The easiest way would be to tell your kids where to find the games and stuff they are interrested in. (Activities -> Application, and then on the right hand side categories)

2012-08-07 18:09:27 -0600 answered a question How to install a intel video driver on Fedora?

intel video drivers are included in the kernel and should work out of the box. Sometimes you have to switch to a newer kernel to get old intel mobil chipsets to work.

what is you Chipset? is this an laptop?

did you already tried upgrading to the latest kernel in fedira?

  sudo yum update
2012-08-07 17:58:47 -0600 commented question Fedora 17 64-Bit Building Guest Additions Module [failed]

you should definitely consider using KVM. the "guest additions" are part of every linux kernel since 2.6.x and work out of the box.

2012-08-07 17:54:44 -0600 answered a question /boot missing

are there other options in grub? Like memtest or other Fedora lines?

looks like the vmlinuz file for the current kernel was deleted.

If you can boot the other lines you can install the latest fedora kernel and this package should again contain the needed vmlinuz.

sudo yum install kernel

if there are no other lines to boot from, you can boot the live cd and chroot into your system:

sdxY = Your Partition with Root on it

sdzY = the partition of /boot

su -
mount /dev/sdxY /mnt 
mount /dev/sdzY /mnt/boot 
mount -o bind /dev /mnt/dev
mount -o bind /dev/pts /mnt/dev/pts 
mount -o bind /sys /mnt/sys
mount -t proc /proc /mnt/proc
cp /proc/mounts /mnt/etc/mtab 
for i in /dev /dev/pts /proc /sys /run; do sudo mount -B $i /mnt$i; done 
mount -o bind /etc/resolv.conf /mnt/etc/resolv.conf 
chroot /mnt /bin/bash

now you can again run

yum install kernel
grub2-mkconfig -o /boot/grub2/grub.cfg
2012-08-01 19:03:05 -0600 answered a question What provides libpanelapplet?

hint: it's possible to let yum search for the correct package:

yum install 'libmysqlclient.so.18()(64bit)'

this also works for binaries

yum install '*bin/wget'

()(64bit) is only needed for 64bit libs.

2012-05-08 19:33:45 -0600 answered a question Why are there 2 sets of boost packages, boost and boost141?

sounds like some packages depend on the older version.

Anyway: I looked at the configure.ac file of electric sheep: http://code.google.com/p/electricsheep/source/browse/trunk/client_generic/configure.ac

REQ_BOOST_VERSION=103900
AC_MSG_CHECKING(for libboost >= 1.39)

So both versions should be fine.

  • resize the windows partition with windows tools (like bootcd)
  • install fedora (use the free space)
  • fedora should install grub and you should get the option to boot win7 or fedora.

Alternative way:

Click on the top left Corner (Activities corner) [also pressing the WINDOWS button does the same].

Type "background" and select the matching icon.

(remark if you have installed an none english version of fedora you may have to search for your local translation of the word background)

Looks like an kernel acpi issue. Do you have disabled acpi=off in the grub modline?

maybe you can to a tracepath and then ping every hop and check where the problem starts occuring.

2012-04-10 16:55:27 -0600 commented question F16 freezes on boot

sometimes adding acpi=off helps. (or removing rhgb from modline in grub) - which should display more output.

2012-04-10 16:52:07 -0600 answered a question AMD Athlon 64

You can try removing

rhgb quiet

from the grub.cfg file. with

sudo gedit /boot/grub2/grub.cfg

this should give you more verbose output.

You can also try giving your PC more time to startup. I once experienced a bug where it took nearly 3min to start (iscsi service is delaying system startup)

Grub2 config are created with

sudo grub2-mkconfig -o /boot/grub2/grub.cfg

The parameter are taken from: /etc/default/grub

Fedora 16 uses systemd to start deamons as far as i know. I checked my (fresh) f16 and i found the following crond related links:

/etc/systemd/system/multi-user.target.wants

contains a link to:

lrwxrwxrwx. 1 root root 33 Nov 3 03:29 crond.service -> /lib/systemd/system/crond.service

2011-12-25 17:31:14 -0600 edited question F16 gnome shell crash on login

i experience quite regular gnome-shell crashes. [about once every 4 logins]

Symptoms:

  1. Create new User without gnome shell extentions
  2. login
  3. delay of about 14sec
  4. "Oh no. Something has gone wrong. Try logout" Message
  5. Logout
  6. Login (this time it always works)

i'm new to fedora and the automatic bugreport does not show an line for these sort of crash. i have an nvidia graphics card and haven't installed proprietary drivers.

I have disabled SELinux with enforce=no in grub and SELINUX=permissive in /etc/sysconfig/selinux
