I don't know how to modify the:

sed -r 's,.*(http://[^ \"$]+).*,\1,'

command, to not just:
$ echo "test string http://somewhere.uk/ test" | sed -r 's,.*(http://[^

http://somewhere.uk/

rather output this:
test string http://somewhere.uk/ test

can some perl/bash gods help me? :)

I know nVidia in their (wisdom?) have dropped the idea of supporting
hSLi in Linux, so I was wondering if I can ever expect to be able to use
the more powerful graphics potential in Linux?

Since updating to the 2.6.32 kernel,if I enable hSLi Linux fails to
boot. I suspect this is because it detects the other GPU but cannot
initialise it properly.

Rest assured I am well pleased with Fedora 12 and KDE 4.4 and wish to
express my appreciation to all those people that made it possible,and of
course the people who provide valuable feedback and assistance on this
forum.

Hi,

It has been several years (literally) since I have had major sound problems
under Linux, since sound support has gotten much better. However, my sound
recently stopped working, and I'm mystified. I'm using an HP Pavilion
dv9700, which I believe uses an Intel HD audio card. I've gone through a few
kernel upgrades on this machine recently, but support for these cards is
enabled, so I can't imagine that's the issue. My sound card isn't listed on
inspection of /proc/asound/cards and /dev/dsp is missing, though with the
deprecation of OSS maybe this isn't even an issue.

Dear list!
I've a nice chinese mobile phone [1] and would like to use its webcam
on F12 [2]. Connecting it through ISB-cable results in errors [3]. I
can't find appropriate solution in google. But as I can see there's
some problems with usb 2-2 support in my kernel and this particular
phone model. Is there an option I should add to kernel boot parameters
[4] in order to disable USB 2 support? Will it work after that? Is
there a better solution?
Thanks in advance!

Dear List,

I am finally getting into selinux. Can anyone on this list recommend a

Is there a way to be able to do a list command like ls -alt to see the

I'm starting to play around with MySQL and PHP on fedora 12.

With Fedora's fanatical devotion to churning out latest
versions of everything, I'm just wondering what the rate
of new MySQL versions that are non-backward compatible
has been like.

Would I be better off using mysqldump and restoring databases
across fedora releases as time goes on, or is just restoring the
/var/lib/mysql datadir sufficient to retore databases most
of the time?

Just curious about the best way to approach backups if I
actually accumulate any useful data in these experiments...

In looking over the reviews of Fedora 12, I was shocked that a big piece
of the possible Fedora 12 experience is missing: KDE.

I just discovered KDE. I don't know why I didn't use it sooner than
this. Now is it just my brand-new hardware, or the massive improvements
that Fedora has seen over the last several years, or is KDE the desktop
to beat?

Sure, I had a learning curve--like how to use the new Desktop Folder as
a widget, and how the wallpaper actually shows through it wherever you
need to place it. And how to use Desktop Activities, and the K App
Launcher.

Maybe you'll remember I had problems opening files in Firefox from
TBird. If I clicked a link, it wouldn't automatically open in Firefox.
Here's the solution.

Under Edit => Preferences => Advanced => General, you have "System
defaults" which says "Always check to see if Firefox is the default
browser on startup". This option should be checked under all
circumstances if you plan to use Firefox by default. Here's why I
didn't check it.

While checking other options a while back, I saw this one and thought
I didn't need this as I only use Firefox to view html files.

I tried to prevent buggy programs from bringing my system to a halt by
setting an RLIMIT_DATA with "ulimit -d", but I discovered that the limit
has no effect due to a glibc behavior. I reported this as a bug:

https://bugzilla.redhat.com/show_bug.cgi?id=569714

I am convinced that this is an infelicitous behavior that deserves at
least a WONTFIX, but the assignee seems equally convinced that it is
NOTABUG, and I do not understand the terse justification given. I don't
want to go on reopen warring forever. Could I please have an outside
opinion?

Hi,

Let me begin by apologizing for not being able to give more info about this
problem than what I do, but I simply don't know how to go about it. I have a
MacBook Pro (5,2) on which I have happily run FC11 for some time. Tonight,
while I was working on something a message about suggested updates popped up
and for the first time I did what I've never done before: I clicked "Install
all updates" without checking what it was. I then left off. When I came back
the screen had frozen. I did a forced reboot but now the computer hangs
after the GRUB screen.

ABRT has reported several kernel dumps and
I was not able to get the report sent, so I deleted
the report entries and moved on.

However, I was perusing the /var/log/message log
file and found the following but do not know what
to make of it, perhaps you might know?

hello,
I am trying to config a y04g0033 tv remote control using my tv card for use
with several applications.
however only few buttons are being recognized and all others are not, the few
are the numbers and the enter buttons.

I know all the buttons are working properly and as well that the signal is
good, trying to cat /dev/input/event7 i can see that all buttons are received.

I am trying to configure the remote to work with mplayer and xmms.

thanks,

hey

I know this isn't an OS question, but I'm lost!!

New to configuring Postfix, with a few questions about how to configure Postfix.

I'm running Fedora, with Postfix, from the basic yum install. The
Sendmail process has been stopped.

I can easily send a basic test mail from the cmdline. Ie:

mail <...> at gmail dot com
subject: blah
test
.
Cc:

works with no issue.

First time posting to here, so forgive me any slight mistakes.
In the past, where I've been inexperienced with an SELinux setup, I kept
telling the troubleshooter to ignore alerts, rather than doing something
about them and having them bother me often.

Hi all,

Don't you know anybody please what could be a reason that records of /var/log/secure stopped coming? Couldn't it be due to hacking the box? :(

Thank you for any help.

Hello,

On a machine I do not use very often, I just pulled in the updates

And I need it, now. This is a big disaster. This is Fedora 13.

What can I do? Thanks.

I'm running an FTP server on an FC12 box (using proftpd) and I've also
enabled the iptables firewall.

I've made the following config changes:

Changed /etc/sysconfig/iptables-config to have:

IPTABLES_MODULES="nf_conntrack_ftp"

Added /etc/modprobe.d/netfilter.conf and put in it:

options nf_conntrack_ftp ports=21

(you can probably skip this step, as it looks like the defaults for the
module are correct...

Hi, someone have noticed regard this issue in evolution 2.28.2 on f12?

For some message, the attach icon is not show and seems that the message
is without attach.

In "schermata-1bn.png" is show the problem: the focus is on message
"indirizzi", which has a "indirizzi.pdf" attachment, but the attach icon
is not show left subject.

This happens only with some message (in "schermata-2bn.png" is OK) and
in all evolution version of f12 (with f10 this problem does not occur).

Someone have some suggest?

Is this a bug?

Many thanks.

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.

Fixed by updating nautilus.
Yes, I should have applied all the updates immediately
after the install, but as usual we were in a rush.
More haste, *much* less speed in this case.
I live, and sometimes learn...

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.

Hi

I have been following recent threads about the best way to clone/backup
disks.

"Risks of backing up live mounted filesystems using dump(8)"

I have just tested dump/restore using a System Rescue CD
using dump 0.4b42

The source /dev/sda7 is a fully working updated F12 / partition
(including /boot)

The destination is a similar partition on the same disk /dev/sda9

mkfs -t ext3 /dev/sda9
mkdir /mnt/out
mount /dev/sda9 /mnt/out
dump 0f - /dev/sda7 | (cd /mnt/out; restore -rf -)
40GB dump/restore took 46 minutes

I received 9 errors of the type

Kevin,

I must apologize for not responding to your earlier post in a timely manor, I had system problems on a different system with the radeon driver which is still broken for me.

With kde 3 I was able to define the right button in the desktop to bring up the desktop menu where I put "save session" for example, and the middle button in the desktop to bring up the application menu; the left button in the desktop was a no-op. This was in effect for all desktops; I usually have 6 or more configured. It looks like kde4 has enabled each desktop it's own config options.

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?

I have once was able to have a fully active remote
network connection to a .gvfs mounted filesystem from
which I could do a 'tail -f /file.log, but
now, it does not work. It works on F9, 10, and I am not
sure about F11, but definitely sure that F12 does not.

Has this been reported before, is this considered
a bug, or is intended by (new) design?

I'd really like to have a "database" for storing
information about contacts (as in an address book).
My base is Fedora/KDE.

My requirements are:

1. The application should be web-based,
like CUPS, BackupPC, etc.

2. There should be a simple interface with mobile phones.

3. There should be a simple interface with KMail/KAddressBook.

4. The program should be sufficiently flexible
to allow new fields (eg images) to be added.

5. The program should allow general information
eg about films or books to be stored.

I've been having various issues with pulseaudio since upgrading my F10
box to F12 recently (it was previously working fine).

The core issue seems to have been worked around my my disabling gdm
puleeaudio (via root's gconf-editor, as mentioned on a blog somewhere).

I'm concerned, though, that that's just masking the real issue.
Essentially, the issue is that, with gdm audio enabled, any normal user's
app. will hang when trying to generate sound.

Journals make the problem far worse.

Good to know and understand.

On restore you will restore a journal log no longer related to whats on
the media, then risk replaying it and causing further damage.

This makes sense. It was not clear to me that the journal was being stored in the "dump data". If so, can it be disabled immediately before dump(8) and then reenabled immediately after? Some highly volatile file systems (like the Oracle file-based database) claim to support hot backups.

This problem has existed since around January 9. At first, Hulu claimed
that everyone just had to update their Flash version. When people did
this and still reported having the problem, they started ignoring
reports. Lots of archived comments at

http://www.hulu.com/discussions/9

with not a single response by Hulu (the relevant threads are the
non-sticky ones with thousands of views).

A curious incompatibility, it seems, between Hulu.com and 64-bit libflashplayer.so plugin has recently reared its ugly head: streaming video won't play or Hulu won't stream them for whatever reason. Also, any other streaming sight that gets some of their content from Hulu like Fancast.com or SlashControl.com has the same problem with those Hulu videos. Those TV shows, movies, clips, etc. that don't come through Hulu work fine.

When it fails, Hulu reports that there may be a problem with my network.

I would like to know if someone experienced to install texlive-2009

I am running fedora 10. On some computer I installed fedora 12, but in
any of these release texlive still remains with 2007 release.

Is there a way to upgrade texlive under fedora 10 or 12.

BTW. Why texlive 2009 has not been included in f12?

If one wanted to install a rawhide kernel in a running f12 machine I guess
you could do something like
yum --enablerepo development install kernel kernel-devel etc

However there are now rpms in the development directories both for 13/ and
for rawhide/ (and i386 and x86_64) - is there a way to install an f13
(specifically), as opposed to rawhide, package in a system running f12?

Thanks

I was working on a linux box which had a failing disk over
the weekend. It still booted, but flagged smartd errors
and had a couple of damaged files which were fortunately
replaceable (eclipse install tgz).

I booted Spinrite to make the drive readable and then planned
to use system rescue CD and gparted to copy to an identical
drive. Unfortunately, the machine used the default boot
partition (ext3) and LVM for the root and swap partitions.
gpartd cannot currently deal with LVM partitions.

I'm trying to understand how cron works nowadays.
I've been comparing my Fedora-12 laptop
with my CentOS-5.4 desktop,
and am slightly baffled by the difference between them.

On the Fedora-12 system the venerable /etc/crontab is empty,
and the work to be done is listed in /etc/anacrontab .
As far as I can make out, there is a program /etc/cron.d/0hourly
which every hour runs /etc/cron.hourly,
which in turn runs a program 0anacron,
which presumably checks /etc/anacron.daily, etc.

I take it this roundabout process is intended
to deal with the case where a laptop is only running

Hello,
If I set a ramfs file system like this on a Fedora 12 system (but I think it
is the same in general):

mkdir /ramfs

I can see it via mount but not via df command.
[root at tekkaman ~]# mount
ramfs on /ramfs type ramfs (rw,size=10m)

As ramfs is dynamic and can go beyond initial set, how can I see how much
memory is using?

[root at tekkaman ~]# dd if=/dev/zero of=/ramfs/testfile bs=1024k count=30

Hi,
I've been looking at this for some time in both the
archives of the list and the web in general. The problem
is that when my Fedora 12 machine is connected though the
KVM (Apex Outlook 8 port) the monitor shows up as "Unknown"
and the resolution is limited to 800x600.

If I plug the monitor directly into the machine, it resolves
just fine and I have the full range of resolutions.

I tried an number of things so far and the one which seemed
most promising was to plug the monitor directly into the
machine and go to run level 3.
