I'm not certain I follow how the ISP gets involved with the definition
of localhost in /etc/hosts, but I haven't seen any reason not to call
the lack of an IPv6 definition for localhost (specifically not
"localhost6") a bug and to try to get it fixed.
My inclination is to file a bug against the F11 alpha when it comes out
next week, since it's anaconda that creates the default file content. I
expect some resistance to change, but I can only hope that BZ doesn't
become the venue of a debate on it, though.

Slooooow USB key speeds
by Ranbir
Hi All,
I have a Kingston 8G DataTraveler USB stick. When I plug it into one of
the USB 2.0 ports on my Fedora 10 PC (x86_64), the kernel detects it,
and after some magic, Gnome mounts it on my desktop - everything is
honkey dorey.
When I use Nautilus to copy files to it (say a 1 GB movie file), the
transfer speed begins in the 20 MBps range, but quickly drops to 1.5
MBps or less. Obviously, this increases transfer time exceptionally,
essentially rendering the USB stick useless.
I've tried reformatting (as vfat) the stick, deleting and recreating the
partition on it, all several times and to no avail.
The same stick works just fine on my HP Compaq nx7400 Fedora 10 laptop.
I now assume something is either amiss with my PC, or there's a bug
somewhere in Fedora 10 killing USB performance. I've tried searching
for both, but I've come up up with nada.
My PC has an Asus P5Q-E motherboard, an Intel E8400, and 4 GB of RAM. Is
there something about this combination of hardware (don't forget the USB
stick) when used in conjunction with the x86_64 version of Fedora 10,
leads to shitty USB performance?
Regards,
Ranbir

Poor WiFi Performance
by Phil Bieber

Hash: SHA1
Hi everybody!
I've recently switched from Ubuntu to Fedora 10 to escape a nasty
problem I'm having but without luck.
I have a DELL Inspiron 640m / e1405 notebook based on a Centrino
chipset with an Intel 3945abg WiFi card and my network connection is
painfully slow. I have a 16MBit/s ADSL connection (according to the
router 14069 kbit/s down and 1189 kbit/s up) and when trying a speed
test I get the following results with Epiphany on Fedora 10:
Down: 200 - 250 kbit/s
Up: 60-80 kbit/s
With Internet Explorer 7 on Windows I get the following:
Down: 7500 - 9700 kbit/s
Up: ~1100 kbit/s
I tried it 3 times on both OS's and within about 10 minutes. The
results from my Fedora tests are way better than expected, because it
sometimes takes up to 5 minutes to open google...
The WiFi network I'm connected to is a WPA encrypted G network with
the AP about 5 meters away from my notebook.
I already did some googling but so far I haven't sound anything that
helped. I even tried the Windows drivers using ndsiwrapper but I
couldnt get them to load properly.

Preupgrade failure
by Timothy Murphy
I've been trying to upgrade a Thinkpad T23 (ie very ancient) laptop
from Fedora-9 to Fedora-10 by running preupgrade.
The first stage - downloading the RPMs, etc - works fine,
and when I re-boot the install.img gets downloaded OK.
But then I get an error message suggesting that I "Try re-load".
I've repeated the process 3 or 4 times without success.
Fortunately, the old Fedora-9 system still seems to work fine.
I vaguely recall reading about some magic formula
that I can add to the Fedora-10 install entry in grub.conf ,
but have not been able to find this with google.

Where are the latest updates??
by Heiko Adams
Hello,
on 29th January the fedora-package-announce list has announced several
package-updates for fedora 10.
But since today (31th January) yum didn't find any of these updates in
the updates repository. Normally all announced updates are at least on
the next day available.

Radio suddenly appears.

I sat down to read my mail. Suddenly when I open firefox I get a radio
broadcast in Spanish. It lasted for 10 minutes no matter what web
location I was at, then suddenly it stopped.
Any explanations out there.

Understanding the mystery of printing?
by Tom Horsley
I just got a new HP Photosmart C5580 which can (among other things)
print on inkjet printable DVDs and CDs. My current goal (probably
hopeless :-) is to tweak the .ppd file for the copy of the printer
I made which defaults to the DVD tray and DVD paper size so that
any application I care to print from will print in the middle
of the DVD (a quest that will probably take years and cost
thousands of lives :-).
My first big mystery came with sample printouts I made of a
hashmark pattern I could use to measure how far off from the
center I am: Both inkscape and gimp print the pattern with
the exact same offsets from the center of the CD, but open
office prints with a completely different offset.
As near as I can tell, I've told every app the page size is
the same and there are no margins. They all print the marks
scaled the same with the same distance between marks, so
does anyone have any clue why open office thinks the center
of the media is in a different place? Is there some obscure
printer setup option I missed somewhere in OO?
Even if I can figure how to tweak the .ppd file, it won't
do much good if different applications use it a different way :-).

Where to get the java plugin for F10. I'm using F9
by Nigel Henry
Where do I get the java plugin from for F10. I'm using F9, but have problems
with some java sites, and believe that the F10 version of the plugin resolves
these problems.
I've already tried altering my sources list in apt to the F10 everything repo,
but am getting parsing errors, which is annoying to say the least.
All I want to do is download an rpm for the the java plugin for F10, but can't
find it anywhere. and I have tried google, but that's a waste of time.
A link would be helpfull, and I'd be most gratefull for that.
Nigel.
