mounting NFS directory with read write access
by Ranjan Maitra
Hello,
I have tried mounting the following remote directory:
sudo mount machine.name:/home/directory -w /mnt/directory
I can mount fine, but I can not write as a mortal user in this
directory.
What should I be doing here?
Many thanks,
Ranjan

F18 freeze
by Michael Eager
I'm having periodic freezes of F18. The freezes happen when
I click on a link. Usually this is in a Thunderbird window,
but I've seen one freeze when clicking on a desktop icon. The
system will work for a day or several days between freezes.
When it freezes, the screen is frozen, mouse is unresponsive,
and any sound which was playing repeats. I can ping the system,
but SSH does not respond. The system logs show nothing.
I recently upgraded the system from F15 using Nvidia drivers to
F18 with nouveau driver. Power management is turned off.
I've searched online and find some suggestion that there is
a problem with X and the nouveau driver. Other suggestions
about overheating or other hardware problems are unlikely.
Any suggestions?

F18: unpredictable 'Predictable Network Interface Names'?
by Franta Hanzlík
Hello, know someone how work in F18 network interface naming? Or when
is there any docs for this?
In this my case, I want MAC-based interfaces naming.
I found these two documents:
https://fedoraproject.org/wiki/Features/SystemdPredictableNetworkInterfac...
http://www.freedesktop.org/wiki/Software/systemd/PredictableNetworkInterf...
but it seems as first isn't too detailed and say about F19, and if
I did (according to second) udev rules, then nothing happens, as if
they aren't there. My rules:
$ cat /etc/udev/rules.d/70-moje-net.rules
# Bus 01:00.0 - PCI device 0x1969:0x1048 Atheros Attansic L1; atl1:
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:1e:8c:93:b5:8d", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"
# External PCI device 0x8086:0x10d3 Intel CT Desktop Adapter w. 82574L; e1000e:
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:1b:21:69:5f:74", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"
# External PCI device 0x1186:0x1300 D-Link System Inc DFE-528TX w. RTL8139; 8139too

These rules works in F17 and earlier versions.

F18 grub hang with blinking cursor after kernel update
by Mike Zingale
I just did a yum update and got the 3.7.9 kernel for F18. Upon reboot, the
grub screen never appears, no prompt or anything, just a blinking cursor in
the upper left. The system just hangs there.
I booted the install disk, rescued, did a chroot to the system image and
remade grub2.cfg and reinstalled grub2 (with grub2-install), and still the
same issue. I even yum removed the kernel that was just installed and
redid grub2, and again, nothing.
Any ideas on how to fix grub on this system?

optional mounts in fstab?
by Bill Davidsen
I have a system used for backups, and when it boots it *may* have any or all of
a number of small hot-swap RAID storage units connected by eSATA. Ideally I
would like the system to fsck and mount these when present, using the UUID=
option in fstab. There's a problem. If the units are not connected the system
tried to fsck them anyway, considers them missing, and doesn't complete boot.
Defining the mount as "noauto" doesn't help, the boot still tries to do the
fsck, and still fails. Moreover, I really want the unit mounted if present.
Next I set the fsck field to 0, which does prevent unwanted fsck, but also
doesn't fsck even when the unit is attached and detected. More "doesn't do what
I want" behavior.
I might be able to hack the behavior I want into udev, but it would be a real
non-standard behavior there.
I thought the 'nofail' option would solve the problem, but that appears to be a
very recent option, and not in RHEL running on this server.
Any thoughts gratefully accepted, we try to keep vital infrastructure running on
RHEL rather than Fedora, for obvious reasons of stability and avoiding having to
upgrade and re-certify every six months.

Google Earth runs for all users except me
by Jonathan Ryshpan
I have just installed the proprietary nvidia drivers on an x86_64
system, and have found that google-earth runs correctly when invoked by
any user except me (root, guest, etc.), but not when invoked by me (that
is jonrysh). The symptom is that when invoked jonrysh everything works
correctly (sidebar, top bar, tour guide, etc) EXCEPT for the main
window, which is supposed to show the world image; this window is black.
When invoked by any other user, google-earth runs exactly as expected.
The problem is not bad data in ~/.googleearth; when .googleearth is
deleted from my home directory things continue as before.
System Details
CPU: AMD 64-bits, 4 core
Video: GeForce 8400GS
OpSys: Fedora 17 with all updates
Driver: kmod-nvidia-3.7.3-101.fc17.x86_64-304.64-2.fc17.5.x86_64
Has anyone else seen this? What's the best way to investigate?
Thanks - jon

System Error After Upgrade to latest Kernel.....3.7.9-201.fc18.i686
by EGO-II.1
I think I may have figured out the problem. After trying to repeatedly
get the update to go from clicking on the entry in the Gnome Menu, I
decided to just run "yum update --skip-broken"...and immediately the
entry disappeared, and I was "allowed" do download and install all 11
updates. Gotta love that Terminal! SO thanks to all for giving whatever
help you could...and a "Special" shout out to Reindl Harald, who
instilled in me the notion of "READING TO FIND AN ANSWER BEFORE ASKING
MY QUESTION! LoL!
Cheers!

running a namecaching server on my notebook?
by Robert Moskowitz
I am upgrading my DNS server and observing all the traffic on it. My
notebook's queries resulting from web access is a frequent occurance.
Does it make sense to run a namecaching service on a notebook? Many
websites I hit multiple times per day, let alone system boot.
Any downsides? Particularly when I am roaming Wifi connections? Perhaps
would be best to flush my DNS cache everytime I go to a different
connection?
thanks
