Strange LAN Problems

**EdT** · 01-24-2006, 08:28 PM

( I'm sorry but my english is not very good

)

I have the Knoppix 4.02 installed on the hd. I gave the following commands:

Code:

ifconfig eth0 192.168.0.69 up
route add default gw 192.168.0.1

I also put some DNS in the file /etc/resolv.conf.
The problem is that only sometimes I can ping 192.168.0.1 (or use internet),
because the PC seems disconnected from the network.
This fact happen about 2 times on 3

.

In this times when I'm disconnected if I give a "route", it takes a very long time
(about 30 seconds) to print the second row of the table.

Can you help me?
Thanks

In order to make this more stable, you may wish to edit the /etc/network/interfaces file to reflect your usual conditions, then restart networking.

As networking is so tightly tied into the operating system, I find that using the init.d script to reset everything is usually the best way to go.

(Then again, it may be an ipv4/6 issue which search for several discussions here.)

have the Knoppix 4.02 installed on the hd.

This might be the problem right there. I have seen many instances where HD install breaks networking.

What's strange about the network breaking when you "install" Knoppix to hard disk?

Thank you for the help...

in the file /etc/network/interfaces i found this code:

Code:

# /etc/network/interfaces -- configuration file for ifup(8), ifdown(8)

# The loopback interface
# automatically added when upgrading
auto lo eth0
iface lo inet loopback

iface eth0 inet static
        address 192.168.0.69
        netmask 255.255.255.0
        network 192.168.0.0
        broadcast 192.168.0.255
        gateway 192.168.0.1

I have to add also "route add default...."?
However i tryed to restart some scripts in /etc/init.d/ and I had this output:

Code:

root@Box:/etc/init.d# /etc/init.d/ifupdown stop
Cleaning up ifupdown...done.
root@Box:/etc/init.d# /etc/init.d/ifupdown restart
Setting up networking...done.
root@Box:/etc/init.d# /etc/init.d/networking stop

Setting up IP spoofing protection: rp_filter.
Reconfiguring network interfaces...SIOCADDRT: File exists

done.
root@Box:/etc/init.d#

(also when I am correctly connected)
