Wireless USB slow to connect
by Brian Wood
I'm using a Linksys wireless usb on a machine with
Fedora 12. Sometimes it takes 40 to 50 minutes to
get the connected to the 'ee' network I want. A Windows
XP box that has a different wireless adaptor is able to
connect to the 'ee' network without any problem. Any
suggestions on how to decrease the time it takes to
get a connection? Thanks in advance.

(OT) Generate Graphical Tree (SVG / PNG) of Directory Structure
by Armelius Cameron
Hello,
First, I apologize for the OT question, but I figure this list is one of the
best resources that may be able to answer this. I have attempted a Google
search for this, of course.
I am wondering if anyone knows any tool to generate a graphical representation
of directory structure as a tree. Directories would be a node, files would be
leaves. I know about the command line "tree". It's similar, but not exactly
what I need. It'd be nice to be able to rotate something like the output of
"tree" command line 90 degree, so that the siblings are on the same horizontal
level. Also, preferably the output is in SVG, so I can edit it using e.g.
Inkscape. But if not, I guess other formal (i.e. PNG, PS) is a possibility
too.
I know about Graphviz. So if I can't find anything I guess I can try to do this
myself and code up something. I just didn't want to do the work if something
is already out there :) . If there are other tools similar to Graphviz (maybe
something simpler), I'd like to hear about it too.
Any help ?
Thanks in advance.

Yes, if you read my original message, you'll see that I always use the
rawread script for reading, which is referenced at the end of [1] as a
better way of doing the same thing (since it can be used in a pipe
instead of having to write the entire file to disk, as the isograb
script does). My comments in bugs #186512 and #397141 (marked as a
duplicate of #186512) describe how I experience the premature read
failure while using this script to do the reading. Mediacheck also
fails with these discs (except when using the F7 installer's
mediacheck). The fact that the read works properly with the original F7
kernel shows that the entire ISO is actually on the discs.
This problem is not too hard to reproduce - take a CD-R, burn a ~650-700
MB ISO using wodim/cdrecord in the simplest possible way:
wodim dev=/dev/cdrom file.iso
which uses TAO mode by default, and if you try to read it using rawread
in an optical drive which triggers the readahead bug (about half to
two-thirds of the drives I've owned have this problem), you'll see the
read errors less than about 150 KB from the end (roughly 1/4000-th of
the entire image). My father also saw it with a F8 DVD bought online,
so it's not limited to CDs. After explaining the problem to the vendor
and asking for a replacement burned properly (with zero-padding), he
just sent an identical disc with the same problem, so instead of trying
again, we just read off everything except the last few dozen KB, used
wget -c to download the rest (which even on dialup only took a few
seconds), then burned our own disc using zero padding, which passed
mediacheck.

I have a pile of old CDs, burned without zero padding years ago, which
disagree with you. For example, see
https://bugzilla.redhat.com/show_bug.cgi?id=186512
which I reported 4 years ago and is still unresolved (and Alan Cox, who
probably knows more about the readahead bug than either of us, has
looked at it, so there's nothing obviously wrong with my report). The
effect of the readahead bug is to prevent the last few dozen KB of the
ISO from being read. I've done plenty of experiments.

Disk error??
by L
Hi
The hard disk on a laptop shows failing error "Disk had many bad
sectors' it suggests 'backup data and replace disk. Of course, this
test information was generated by Palimpsest Disk Utility on F12.
However, when I used self-test utility from BIOS (HP 6710), it passed
all tests.
Which result is reliable, one from Palimpsest Dish Utility or BIOS
self-test utiltity?
if this disk is failing, how can I check what section or partition
where errors reside?
Best
Y

To upgrade or to change to a more 'stable' distrobution
by Seann Clark
All,
I am polling for options on some of my servers. I have two that are
out of date now, one sorely out of date (using Fedora 8) and I am
wondering what the best path to upgrading that would be. I would go over
to CentOs on it, but I don't know how stable the move out be or what the
level of effort would be on that, so I am polling for answers. I could
also upgrade it to the latest Fedora if that is painless, per say. The
other system is too large, in terms of file system to effectively back
up (3.2 Terabytes of space) given my current means, and that system is
on Fedora 9. Using pre-upgrade in theory would work, but as I haven't
used it, I am not sure how it would impact the box, especially the VM
side of things, as I know the kvm functionality is changed just
slightly. Any suggestions would be welcome.
Regards,
Seann

I'm not sure what you mean by "requested number of bytes", since your
command doesn't request a specific number, but relies on the OS to
detect the correct size of both files (which in the case of /dev/dvd is
unreliable). Your description of the possible outputs of the cmp
command seems to imply that the readahead bug would cause /dev/dvd to be
seen as bigger than it actually is, which is the opposite of what
actually happens - there would be read errors on /dev/dvd _before_
reaching the true end of the image (making it impossible to read off the
full ISO, even assuming its exact size is known).

nfs issues between fc11 and fc12?
by Gary Artim
Hi All --
wondering if anyone has had any problems with nfs between an
fc12_nfs_server and fc11_nfs_client? I have a client that periodically
hangs on doing something like:
tree /mynfs
or
find /mynfs
Basically a full metadata listing of the nfs share. The nics look fine
and the routing looks ok, no nic errors reported on either side. The
network has been stable. I did have to
change IPaddresses, but it was a basic switch from 10.0.0.1 to
10.0.1.1 on the server and 10.0.0.253 to 10.0.1.253 on the client.
Thanks for any input!!!

disk druid !!!!! why like this ???
by Jatin K
Dear *,
I've facing one problem ( doing partitioning practice on 10GB IDE
hard-disk )
I'm trying to create following partition layout
--------------------------------------------------------------------------------------
device size mount-point
--------------------------------------------------------------------------------------
hda1 100mb /boot
hda2 500mb swap
hda3 5000mb /
hda4 4500mb Extended partition
hda5 500mb /var
hda6 1000mb /var/www
hda7 2000mb /home
hda8 1000mb /usr
-----------------------------------------------------------------------------------------
I've done this on disk druid
licked on new ---> mount point */boot *filesystem type ext3 100MB (
fixed sized is selected ) and it becomes hda1
again licked on new ----> filesystem type Swap 500MB ( fixed sized is
selected ) and it becomes hda2 ...
now creating / ( root ) partition
again clicked on new ---> mount point */* filesystem type ext3 5000mb (
fixed sized is selected ) ... now something happens as soon as I press ok
the swap partition is sifted to hda3 (previously it was on hda2 ) and /
partition goes to hda2
if I go ahead with this and create other partition / goes to hda5
why like this ????
how do I exactly maintain the said order of the partition in exercise ??

F12-i386-DVD iso won't burn properly
by Temlakos
I have downloaded this ISO twice, and verified it each time. I have made
no less than three "coasters" while trying to create a DVD from it. Then
I moved the ISO to another machine, and another program--which then
proceeded to tell me that the ISO looked like a CD, not a DVD.
What's going on? Has nobody noticed that the DVD ISO is no good, and
that the six-CD install set, or one of the two live CDs, are the only
options?
