Fedora 10 – Could not create a python script engine for plasmoid

This is my solution:

Remove any plasmoid and its directory in $HOME/.kde/share/apps/

yum remove kdebase-workspace-python-applet

yum install python-dev compat-python24-devel.i386 compat-python24-tools.i386 dbus-python-devel.i386 gnome-python2-devel.i386 ipython.noarch  pymol-wxpython.i386 python-devel.i386 python-fedora.noarch python-py.i386 python-pysctp.i386

yum install kdebase-workspace-python-applet

the re-install plasmoid with command:

plasmapkg -i plasmoid

plasmapkg -i 101229-gmail-plasmoid-0.7.3.plasmoid

madwifi-ng driver on fedora 8 and packet lost

Questi i passi necessari:

svn checkout http://svn.madwifi-project.org/madwifi/trunk/ madwifi-ng

madwifi-unload

cd madwifi-ng

make clean && make && make install

modprobe ath_pci

depmod -ae

iwconfig wlan0 essid wlan rate 11M

A questo punto ad ogni ping perdevo molti pacchetti. Per risolvere:

iwpriv wlan0 mode 2

in modo da forzare il funzionamento in 802.11b

Adesso tutto funziona!

Error – mount nfs from linux client to windows server

Ho avuto un problema con il mount di una share nfs windows server 2003 r2 da parte di un client linux.
Ottenevo sempre un problema di timeout o un errore di i/o.
Nei log c’era:
portmap: server localhost not responding, timed out

Il problema si risolve avviando il servizio portmap:

su redhat/centos:

/etc/init.d/portmap start

su slackware:

chmod ugo+x /etc/rc.d/rc.rpc
/etc/rc.d/rc.rpc start

Come installare VMWare server su Fedora Core 7

Una meravigliosa guida che spiega come installare vmware server su fedora 7.

http://www.howtoforge.com/vmware_server_fedora7

ecco il cuore della guida:

make[2]: *** [/tmp/vmware-config2/vmmon-only/linux/driver.o] Error 1
make[1]: *** [_module_/tmp/vmware-config2/vmmon-only] Error 2
make[1]: Leaving directory `/usr/src/kernels/2.6.21-1.3194.fc7-i686′
make: *** [vmmon.ko] Error 2
make: Leaving directory `/tmp/vmware-config2/vmmon-only’
Unable to build the vmmon module.

For more information on how to troubleshoot module-related problems, please
visit our Web site at “http://www.vmware.com/download/modules/modules.html” and
“http://www.vmware.com/support/reference/linux/prebuilt_modules_linux.html”.

Execution aborted.

This happens because VMware Server isn’t ready for a 2.6.21 kernel yet (the default kernel in Fedora 7 is 2.6.21.3). Therefore, we must patch VMware Server a little bit. This can be done as follows:

wget http://knihovny.cvut.cz/ftp/pub/vmware/vmware-any-any-update110.tar.gz
tar xvfz vmware-any-any-update110.tar.gz
cd vmware-any-any-update110
./runme.pl

The ./runme.pl command will continue the VMware Server installation. This time it should succeed, and again you can accept all default values. When it asks you

In which directory do you want to keep your virtual machine files?
[/var/lib/vmware/Virtual Machines]

you can either accept the default value or specify a location that has enough free space to store your virtual machines.

At the end of the installation, you will be asked to enter a serial number:

Please enter your 20-character serial number.

Type XXXXX-XXXXX-XXXXX-XXXXX or ‘Enter’ to cancel:

Fill in your serial number for VMware Server.

After the successful installation, you can delete the VMware Server download file and the installation directory:

cd /home/falko/Desktop
rm -fr vmware-server-distrib
rm -f VMware-server-*.tar.gz

You will now find VMware Server under Applications > Other

ATTENZIONE:
Può essere causa di errore l'assenza di xinetd, quindi prima di iniziare l'installazione assicurarsi di avere xinetd:
yum install xinetd

ATTENZIONE 2:
Una altra possibile causa di problemi è la presenza del file
/etc/vmware/not_configured
occorre eliminarlo:
rm /etc/vmware/not_configured

Suspend to ram – sospensione in ram su Fedora 7

Per abilitare il suspend to ram e il suspend to diskho modificato il /etc/grub.conf come segue:

kernel /boot/vmlinuz-2.6.21-1.3228.fc7 ro root=LABEL=/ rhgb vga=791 selinux=0 resume=/dev/sda3 quiet

In questa riga ho:to il suspend to disk e il suspend to ram
abilitato il frame buffer a una risoluzione di 1024x768x32
disabilitato il SELinux
