Thanks for your answer. Here is some configuration: |

What does this mean?: |
| 88 |
# /etc/init.d/net.eth0 start |
| 89 |
* 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 |
| 93 |
times and reports how many times it did NOT have an address: |
| 94 |
#! /bin/bash |
| 95 |
export I=0 |
| 96 |
export FAILURES=0 |
| 97 |
while test $I -lt 10000; do |
| 98 |
export I=$(dc -e "$I 1 + p"); |
| 99 |
export FAILURES=$(dc -e "$FAILURES $(ifconfig eth0|grep "inet |
| 100 |
addr:">/dev/null; echo $?) + p"); |
| 101 |
done |
| 102 |
echo FAILURES=$FAILURES |
| 103 |
|
| 104 |
|
| 105 |
When I run it I get: |
| 106 |
FAILURES=9786 |
| 107 |
FAILURES=9787 |
| 108 |
FAILURES=9779 |
| 109 |
(numbers vary somewhat between runs) |
| 110 |
|
| 111 |
Running the script with the computer connected directly to the Internet |
| 112 |
gives: |
| 113 |
FAILURES=0 |
| 114 |
|
| 115 |
What else should I do? |
