grub2
by Patrick Dupre
Hello,
After the installation of a new kernel (typically during an update).
There is a change of the file /boot/grub2/grub.cfg.
However, the new menuentry created is not correct.
The new one includes
linux /vmlinuz-3.14.2-200.fc20.x86_64 root=/dev/mapper/VolGrpSys_DK1-root
which wrong.
I can change it manually.
I cannot guess where the information is found!
the
set root='lvm/VolGrpSys_DK1-root'
is correct
It does not seem to be in
/etc/grub.d/
It looks like that it takes it from another distribution installed on the
machine, while any of the partition are mounted!
Thank for your help.

How can I sabotage all networking functionality in a fedora system?
by Someone
I'd like to lobotomize a system through soft means such that it has no
way to communicate using any network interfaces. Ideally, in order to
reverse this, one would need the root password, and be required to dig
through obscure configuration files or execute shell commands.
Anyone have thoughts on how one could go about accomplishing this?
Thanks.

Yes, If I switch to permissive then the pdf file is generated.
But on another machine, the file generation is OK even in enforced mode!
(BOTH fc20).

No, I'm planning to install a fedora system to a USB flash drive, and
then give that to someone to boot their machine from. I don't have
details on the hardware of the target machine, but I'd like to ensure
that there's no network activity for the duration of their session in
the environment.
Thanks again

Fedora does not find i/o scheduler
by Chris
Hello Fedora users,
I have a strange problem! I have several Fedora guests on a KVM
hypervisor (CentOS 6.5) and my Fedora guests doesn't show an I/O

Fedora 20 guest:
# cat /sys/block/vda/queue/scheduler
none
I expect something like: (CentOS 6.5 guest)
# cat /sys/block/vda/queue/scheduler
noop anticipatory deadline [cfq]
Thanks for your help.

Disabling users after a period of time
by Renich Bon Ciric
Hello, Fedudes!
So this is the situation:
I have a server called "El Servidor de la Comunidad" or "The Community
Server".
This servers provides old fashioned hosting to GNU & Linux and Fedora
enthusiasts.
Everybody has a shell and their websites are all in /srv/www; owned by
them and their group; allowing the world to enter.
Basically, everything has 2771 from /srv/www and up; until it reaches
the actual document root; where people have what they please.
So, since we're not an ISP; just a bunch o' loosers, we do not have an
idea of when a user needs to renew the yearly subscription, which is
$100.
Anyway, I thought of using usermod -e; which is the expire flag. But
this will not disable their websites along with the user, since the
files are out of their home dir; which we will never support.
So, I need good ideas on how to make their websites go away with a "this
guy doesn't pay... " message.
This is to avoid the possibility of somebody not paying for the service;
which covers the bills for the server.
So, if anybody has a great idea, this is the time to spit it out.
Thanks guys; in advance.
p.s. Please, do not pollute this email with rants about how 2771 doesn't
provide actual security or why should we put stuff at /home; which we
will not do. Focus on clean, simple, ingenious solutions, if you may.

simple scan 3.10.2, mustek 1200 CU scanner, and the lights are off but somebody's home
by Tim
Does anybody have a scanner that identifies as a Mustek 1200 CU (several
scanners are this, under the hood), they they can try with the simple
scan program?
On my Fedora 20 computer, running the Mate desktop, the scanner light
goes out shortly after it does the little test dance, and it scans the
rest of the page with no lamp on. Yet, if I plug the scanner into a
very old Fedora release, or CentOS, it works normally.
It shouldn't scan unlit, there's no option for it, and it's not a
scanner meant for scanning transparencies.
