Networking :: netcardconfig after each reboot?
got it, not pretty, but it works
open /etc/init.d/knoppix-autoconfig with your favorite editor
comment out these lines
if checkbootparam "nodhcp" || [ -f "/tmp/netconfig" ] ; then
echo " ${BLUE}Skipping DHCP broadcast/network detection as requested on boot commandline.${NORMAL}"
else
fi
(not every fi in the doc, just the one in that section, comment those 4 lines by putting a # in front of them, these are lines 856, 857, 858, and 869 in mine.)
all this is assuming that you want to use dhcp and that you append line on /etc/lilo.conf does not contain nodhcp.
Hello there,
I'm having similar (annoying) problems with netcardconfig. Each time I reboot (DSL 0.7.3 HDD install) I have to run netcardconfig so I can get on the internet, although all the settings are still in the progam, all present and correct.
Tried the following as root:
'ifup eth0' from the command line says "ifup: interface eth0 already configured"
Then I run "ifdown eth0" which reports back "SIOCDELRT: No such process"
Then I run 'if up eht0" and the internet starts working again! 
Even tried putting 'ifup eth0' into /opt/bootlocal.sh but still had he above situation.
Does anyone know how to make netcardconfig stick 
EXTRA! Got it to work! Put the following in my /opt/bootlocal.sh :
ifup eth0
ifdown eth0
ifup eth0
The first ifup may not be needed, but the idea working so I'm leaving as is! 
yay!
it was a minor annoyance, but now its gone!
