I am trying to connect my Gentoo computer to my D-Link DVG-1120 (VoIP
Gateway with NAT) again after 3 months. It used to work great, but now
the network status is changing randomly. Sometimes I can load a
webpage,
but then when I click on a link I get an error message. Then it may
suddenly work again. The Internet connection to the gateway works fine
and I can make phonecalls with the phones that are connected to it. It
is the link to the computer that is broken. The computer works when
connected directly to the internet and the cable works perfectly too
(tested elsewhere). I see that it is changing randomly by executing the
command
ifconfig eth0|grep "inet addr:"
repeateldy. Sometimes I get nothing, sometimes I get:
inet addr:192.168.0.46 Bcast:192.168.0.255
Mask:255.255.255.0
It looks random. What can I do about it? Is there some software for
analyzing it?
could you post your config please?
Thanks for your answer. Here is some configuration:

=================================================
What does this mean?:
# /etc/init.d/net.eth0 start
* Service net.eth0 starting
* WARNING: net.eth0 has started but is inactive
I made this script to test how often it fails. It checks ifconfig 10
000 times and reports how many times it did NOT have an address:
#! /bin/bash
export I=0
export FAILURES=0
while test $I -lt 10000; do
export I=$(dc -e "$I 1 + p");
export FAILURES=$(dc -e "$FAILURES $(ifconfig eth0|grep "inet
addr:">/dev/null; echo $?) + p");
done
echo FAILURES=$FAILURES
When I run it I get:
FAILURES=9786
FAILURES=9787
FAILURES=9779
(numbers vary somewhat between runs)
Running the script with the computer connected directly to the
Internet gives:
FAILURES=0
What else should I do?
I have narrowed down the problem further. I am now connected with a
static IP address and it works just fine.
# grep "^[^#]" /etc/conf.d/net.eth0
config_eth0=( "192.168.0.16 netmask 255.255.255.0 broadcast 192.168.0.255" )
routes_eth0=(
"default via 192.168.0.1" # IPv4 default route
)
So I guess it must be the DHCP client on the computer that fails somehow.
