[gentoo-user] KDE fails to start when coupled with firewall...

[Timo Heubach]

Hi,

I have set up a set of rules with iptables so that the default policy of 
all tables is to block all communication if it's not specifically 
allowed in the given table. Now I'm wondering why KDE doesn't start when 
those rules are applicable. It always stops where it should be 
initializing services... What does it need the network for and why can't 
it stop probing if access is forbidden? ...And most of all, what could I 
do to make it all work?

Sincerely,
Timo Heubach

It makes sense to log the packets you drop
to see what holes you may need to open in your firewall.
As a minimum you have to allow traffic through lo interface.
You may find a bunch of howtos and examples on http://www.iptables.org
