Intermittent Wireless Connection in Fedora Core 6
by Jeffrey D. Yuille
Hello,
I recently did a clean install to Fedora Core 6 on my IBM ThinkPad
T-30 laptop. I am using an Atheros-based wireless card with WPA-2
encryption. The madwifi drivers are installed and I have a Linksys
WRT54G Wireless router. I started NetworkManager,
NetworkManagerDispatch, and wpa_supplicant in
"system-administration-server settings-services". I also unchecked
"network". Although I was able to connect wirelessly, the signal seems
to be dropping every 10 seconds or so. After a while, the signal will
stop entirely. Has anyone experienced this problem? By the way, the
wireless router is approximately 2 feet away from where my laptop is.
Any help would be greatly appreciated.

I'm quite sure I haven't been using mpage, as I hear about it for the
first time now. However, I've made some search about it and possibly
the a2ps was calling mpage somehow. At least the default output of
mpage looks similar to what I've been getting from a2ps.
Thanks for the hint with mpage.

e2fsck advice needed
by Michael Wiktowy
Hello,
I have a friend's laptop that was having some strange problems in that
it would start to boot normally and then just stop making any progress
without giving any errors at all.
Since this happens even when booting from a LiveCD, it popped the HD
out and put it into another laptop of mine to do some work on it. I
installed FC5 and yum upgraded it to FC6 and somewhere during that
process it started spewing out bad I/O errors and such so I decided to
boot to a LiveCD and run a fsck on the HD.
Normal e2fsck with no options passed fine. I decided that I should
check for badblocks so I used the double c option (e2fsck -c -c
/dev/hda2). That progressed until about halfway through the disk and
then started going very sloooooow. No errors showing yet though ... it
would update the number once every minute or two whereas the first
half, it was updating it every second or so. Figuring that the -c -c
option was maybe a bit rigorous, I switched to just a single -c and
found the same thing. So I left it over night and was presented with a
bunch of questions this morning that seemed to be coming from phases
of the check beyond the badblocks check.
All of this to lead to my questions ...
What could be causing this massive slowdown on the fsck? There didn't
seem to be any errors popping out during this time but the badblocks
phase seemed to spit out a single number (something in the 500 range).
Is that the number of badblocks that it found?
Is the badblocks info preserved through a format? If I now go and
reinstall FC6 from scratch and choose to format the drive, will it
overwrite that badblocks table?
If it is going to take a long time to run through, I would like to run
fsck overnight. Are the questions that fsck asks set up such that
always answering yes will try to fix the problem and always answering
no will be conservative and do a minimal of fs manipulation?
I know that I should just get another HD at this point (I have already
advised my friend to research the purchase of another laptop and this
is not the only problem with the laptop from what I can gather).
However, I am taking this opportunity to learn about laptop hardware
troubleshooting and if I can ressurect this machine from the dead, it
will save him a few hundred bucks that he doesn't have at the moment.
Thanks for any help that you can offer.

yum prob on lappy
by Gene Heskett
Greetings;
Over the weekend I tried to drag out my lappy and update it, getting ready
to upgrade to FC6, its currently FC5, but about 2 weeks out of date.
To make a long story shorter, what with editing the repo addresses, putting
fedoraproject.org in where downloads-redhat.com was due to the repo or
mirroring failures, I now have a __.000db file that when I shut it down
yesterday, was a zero length file and both yumex and smart package manager
were spitting out terminal tummy aches over it. An 'rpm --rebuilddb' also
fails, as does an "rpm --initdb"
Humm, now this morning, its back to complaining about an "invalid baseurl
for core".
As that _000.db file seems to be missing now, and its not bitching about it
ATM, whats the next step here?, I've been out of the loop since last
wednesday, out on the road. So if its been posted, whats the subject
line?

You can mount an ext3 file system as either ext2 or ext3. If mounted as
ext2, you just don't get journaling. So, just change your mount command
to "-t ext3" and you *should* get journaling.

Hmmmm. Doesn't make sense. The system uses the information in fstab to
construct a mount instruction that should be identical to what you're
providing on the command line.

Thanks. I always wondered how to set a partition label. The pertinent
part of the man page for tune2fs says:
-L volume-label
Set the volume label of the file system. Ext2 file
system labels
can be at most 16 characters long; if volume-label is
longer
than 16 characters, tune2fs will truncate it and print a
warn-
ing. The volume label can be used by mount(8),
fsck(8), and
/etc/fstab(5) (and possibly others) by specifying
LABEL=vol-
ume_label instead of a block special device name like
/dev/hda5.
You should (there's that magic word again) be able to do something like:
tune2fs -L /home/cj/archive /dev/sdc1
From what you said earlier, the system seems to think that
/home/cj/archive is the volume label for /dev/sdb1. I'm guessing the
above will fail with an error saying this. I didn't see anything about
how to remove an existing label although you could probably just use
tune2fs to apply a different label to /dev/sdb1.
One other thing. /home/cj/archive is exactly 16 characters long which
is the limit for labels. I'm always suspicious when something fails
right at a boundary like this. You may want to try a shorter label like
just "archive" since the label is just a name (the system defaults to
using the mount point as the name). Make sure that the fstab entry and
the label match.
Cheers,
Dave

a2ps in fc6
by Honza Valenta
Hi,
in fc4 i used a2ps for processing PostScript files before printing to
print more pages on one sheet. E.g. the command
a2ps -2 -o out.ps in.ps
caused, that in the out.ps file was two pages of in.ps on one sheet. Now
in fc6 I have in the out.ps file the source code of the in.ps file. What
has changed?
Thanks,
Jan.

Can interrupted yum update be corrected?
by Timothy Murphy
I was doing a yum update (under FC-6)
when the machine hung - while updating rekall-sql, to be precise -
after a number of packages had been updated.
I had to stop the process.
I then ran "yum update" again, and it updated the remaining packages,
and cleaned up after them.
But the first lot of packages were never cleaned up.
I wonder if there is any way of re-running the cleanup part of yum
by itself, in these circumstances?
