RHEL, failed to add iptables rule to allow DHCP requests from 'virbr0'

I've just updated my RHEL 5.3 box with the last months' updates moving it to the 5.4 release.

Just after the yum update finished I've begun to receive a LOT of messages containing

OBJECT: python /usr/share/rhn/virtualization/poller.py

BODY: libvir: QEMU error : failed to add iptables rule to allow DHCP requests from 'virbr0' : Invalid argument


The solution to that, after a yum whatprovides "*/poller.py" was to remove any instance of the rhn-virtualization-host from my machine (since I do not have any virtualization need).

Cheers,

     Nicola

getting Flash workin' into Flock (on Linux)

Do you have Firefox installed and correctly configurated with the Flash plugin ?
 
Have you manually installed Flock on /opt and can't see videos on
Facebook or blogs, animations and such?
Well to "cure" your installation all you have to do, as root user is
give this command:
 
ln -s /usr/lib/mozilla/plugins/* /opt/flock/plugins/
 
Enjoy !!!
