Hi,
well, I am not really fully acquainted with network configurations, so
here it comes ... ;)
in blfs 6.0 I have no connection to the internet anymore (it worked
before, I did not intentionally change any dhclient settings, and I did
not build and use a new kernel), In my other two installations in my
computer (currently Kubuntu 7.04 and XP) I have access to the Internet,
using the same network interface (eth0).
When I try to ping google.de in BLFS 6.x, then "ping: unknown host".
BLFS 6.x starts as usual, during boot the message appears:
"Bringing up the et0 interface [OK]
Starting dhclient on the interface [OK]"
Some network information which is present after a boot n BLFS 6.x:

=> according to me the tcp and udp connection to my router is missing.

-------------------------------------------------------------
Steps to resolve the behaviour (which did not resolve the behaviour):
- switched off router (pulled the plug), switched in on again and did a
re-boot
- restarted network service via /etc/rc.d/init.d/network restart
(result in the console: everything "[OK]")
- restarted dhclient on the console
- stopped the firewall locally:
[EMAIL PROTECTED]:/etc/rc.d/init.d# ./firewall.stop
[EMAIL PROTECTED]:/etc/rc.d/init.d# iptables -L
Chain INPUT (policy ACCEPT)
target prot opt source destination
Chain FORWARD (policy ACCEPT)
target prot opt source destination
Chain OUTPUT (policy ACCEPT)
target prot opt source destination
[EMAIL PROTECTED]:/etc/rc.d/init.d#
- used an older kernel which I never used before for dclient based
internet connections
Any help would be very welcome ...
