Re: dvbd - restart after change of ippp0 IP Adress ?

[Mo Hataj <m.hataj@digim.de>]

you don't need to reload the dvb drivers, just pay attention that 
they will be automagically loaded at system start.

that's my /etc/ppp/ip-up and i use squid as a transparent proxy as in 
http://sunsite.utk.edu/LDP/HOWTO/mini/TransparentProxy.html
