Does FC3 need anti-virus? A very good question indeed. Linux and virus hahaha. Even though, you can try BitDefender linux.
To run a scan $ bdc /path/of/dir –all
to update $ bdc –update
Fedora (and generally all Red Hat distro) store information about the boot process messages in these files:
/var/log/dmesg (kernel messages) and /var/log/boot.log (services outputs).
The first log (it can be seen also with the command dmesg) is rewritten at every system restart, the second one mantains the record of past booting activities.
This code determines IP of the machine:
$ /sbin/ifconfig | grep addr | cut -d’ ‘ -f 12 | cut -c6-16
The laptop’s battery’s life could optimise it through CPU Throttling
here are the results:
state count: 8
active state: T0
echo 5 > /proc/acpi/processor/CPU0/throttling
The number five would be related to the T* choice.
Another way of fixing up battery life is to use laptop-mode which spins down the disks and increases the memory buffering so that disk accesses (for writing) are relatively rare.
Preliminary packages here.
(I’m using this package on my notebook and they seem OK but I can’t make any guarantees, it hasn’t seen wide testing. Also, it would be preferable if this was integrated into a broader power management framework instead.)
To get it running as root#service laptop-mode start
/sbin/chkconfig –add laptop-mode
/usr/sbin/laptop_mode has been added to /etc/rc.local
After Fresh FC3 install, cdrom or dvdrom cant be ejected manually and sometimes gives error when ejecting through command line.
To solve the disk error of audio cds after fresh FC3 install as root:
$ cd /dev
$ ln -s /dev/hdc /dev/cdrom
$ chmod 777 cdrom
If ejecting becomes impossible even as root, try:
$ eject /media/cdrecorder

another solution as root mount -t auto /dev/cdrom /mnt/cdrom -o ro
OR even mount -o ro -t iso9660 /dev/hdc /mnt/cdrom/
If you’re like most people you probably have a dual boot system which allows you to boot into either Linux or Windows. So what happens if you need to reinstall/install Windows and you already have Linux installed? When you install Windows it overwrites you’re current MBR/boot loader (in this case GRUB). So how do you restore GRUB after Windows overwrites your MBR/boot loader? Link for Howto
eclipse : jar xf startup.jar
press Ctrl Esc
or using the terminal:
Run the command: ps -ax and look for the process and related number.
Then type kill XXXX.
For example: kill 2345
When I installed Fedora Core 3, Gnome had a handy “Show Desktop Button” on its panel. When I switched to KDE it did not have a Show Desktop button on the panel by default. Here’s how to add one:
Right-click the Panel; Click on “Add” then “Special Buttons” and Choose “Desktop Access”. After this you can drag it anywhere you want by right-clicking it and choosing “Move Desktop Access Button”. I like mine beside the menu launcher.
By the way CTRL-ALT-D does the same thing.
