Question on shredding a terebyte drive
by Dean S. Messing
I have a terebyte sata drive that I need to securely wipe clean. It
originally had 2 partitions. I deleted them using `fdisk', rebooted,
and then as root ran
shred -vz /dev/sdd
The drive is capable of about 60MB/sec, but shred is only "shredding"
about 25MB every 5 seconds according to its output. Since the default
number of passes is 25, this works out to about 5 days.
The `shred' process is running at 100% CPU, presumably computing
the special random patterns for erasure. Since I have 4 CPUs
would creating 4 unformatted partions on the drive and then running
something like:
shred -vz /dev/sdd1
shred -vz /dev/sdd2
shred -vz /dev/sdd3
shred -vz /dev/sdd4
in parallel cut my time? Would be just as secure?
Thanks

Alpine will not show attachments
by Tom Diehl
Hi,
I am running alpine-2.00-1.fc10.x86_64 on an F10 box. If I get a message with
an html or file attachment and I try to open it, I get an error that
"Firefox can't find the file at /tmp/img--46112.htm" The correct program opens
up but I always get the can't find file errors. If the message contains a URL
then it comes up and displays properly.
Does anyone know how to troubleshoot this problem?
Regards,

dell e6500 lost fn-f8 key with 2.6.32 kernels
by Brian Millett
In the 2.6.32 kernels, I've seemed to have lost the ability to use the
fn-f8 key to togle external displays. Using xev I see that
KeyPress event, serial 35, synthetic NO, window 0x5800001,
root 0x15a, subw 0x5800002, time 869383, (55,45), root:(93,132),
state 0x50, keycode 33 (keysym 0x70, p), same_screen YES,
XLookupString gives 1 bytes: (70) "p"
XmbLookupString gives 1 bytes: (70) "p"
XFilterEvent returns: False
KeyRelease event, serial 35, synthetic NO, window 0x5800001,
root 0x15a, subw 0x5800002, time 869531, (55,45), root:(93,132),
state 0x50, keycode 33 (keysym 0x70, p), same_screen YES,
XLookupString gives 1 bytes: (70) "p"
XFilterEvent returns: False
This works just fine with the 2.6.31.12-174.2.22.fc12.x86_64, but not
with any of the 2.6.32 kernels.
Any hints?
Thanks.

Upgrading : give me strength ...
by Beartooth
I've tried all the tricks on this list a/o the troubleshooting
site, over and over. I finally gave up : downloaded and burned a DVD --
and *still* hit the catch-22 error, with too little space in mnt/sysimage/
boot.
Now what?
Can I simply delete all of /boot, or everything in it? All of
grub.conf? Or what? It's going to be a royal pain if I have to burn all
my data to media, and then sneakermail that back onto each machine,
instead of just upgrading f11 ....

gpk-update-viewer vs. yum
by Beartooth
Is it just me??
I've noticed, on several machines (PC, laptop, netbook) that if
the machine has no connection, or thinks it has none, the gpk function
claims there are no updates; but if I doubt that and run yum update, it
may immediately get over a hundred -- or at least report a failure to
connect.
Couldn't gpk do the same??

Enabling Airport wireless on Macbook Air with F12
by Colin Paul Adams
Thanks to Chris Smart, Peter Danenberg and others, I have been able to
install Fedora 12 as the sole O/S on my Macbook Air (first
generation).
However the wirless networking is not enabled.
I am following the instructions in
http://docs.fedoraproject.org/wireless-guide/f12/en-US/html-single/#chap-... .
There was no wireless device shown in the network Configuration, so I
clicked New and added a device for hardware Apple Airport.
I also tried adding wireless device on the Hardware tab (eth0), but although
it allows me to do this, after I save and then reopen the Network
Configuration, the hardware only shows a device pan0 of Type Ethernet
(which was there from the start). It does appear on the Devices tab
(it didn't originally until I added it), but has staus of inactive,
and no means to activate it.
However, even after restarting the computer, the wireless icon on the
panel says there are no network devices available.
So I tried removing the device from control by NetworkManager, and
activated it manually. But then I get:
Device eth0 does seem to be present, delaying initalization.
What do I need to do?

CrossPosting:
A quick scan reveals adjusting fstype will not be enuff, btrfs uses
different userspace tools from ext[34] "btrfs-progs", so livecd-tools
will need a patch.

does Fedora need Google search logic?
by Valent Turkovic
Package search has been bugging me for a long time now, I as an advanced user
know exactly what I want and any package is just "yum install name" away, yes I
still use yum and will continue to do so because I prefer yum over pkcon :)
<rant>
also pkcon is harder spell the phone line or skype (when dealing with
new users),
yum is easier to type even you are regular cli user, and yum is easier
command to
remember but never mind, back to topic at hand.
</rant>
For new users it is too hard to install package by searching because for any
general search phrase and even for searches that are unique package names users
get too many search results, and too often the top result is not what they are
looking for. Too much information is not a good thing.
This has been bugging me for months but haven't written anything about this
because didn't see a solution until now.
After looking at Suse Studio Screencast [1] it become obvious really fast whan
needs to be done because they have done it in really elegant way.
When doing a search in SUSE studio package search results are sorted by
installation frequency. So packages which are most often installed are on top.
SUSE guys have great example by searching for apache package. I repeated apache
search on Fedora with yum, pkcon and with PackageKit GNOME GUI. The results are
attached in this RFE, but you can see how search isn't usable if user doesn't
know exactly that needs to be installed.
Regular users won't go installing apache, this is just one example, but I had
lots of similar situations in real life when I told some fedora users to just
type name of package and to install it, but users got too many search results
and got confused. I expect that only few packages will show and that main
package will be first.
We need some king of google logic that would sort package search results.
Am I making any sense? Has something like this already in the works? Am I just
wasting your time?
