Hi, i have a problem with fedora core 3 and eth.
My pc have two ethernet cards, eth0 is working perfect and used for internet connexion. The other is used for intern network. The problem is that i cant initialice eth1 automatly on start up. Need to enter the orders in console to enable it. How can i do it?

Thanks.

You can put these commands in /etc/rc.local. Mind that you must include the full path to a command, i.e: /sbin/ifconfig eth1 xx.xx.xx.xx and so on.
Or you can create a script with these commands put it in /etc/init.d/ and run "chkconfig scriptname on" to activate it on the various runlevels.

Regards

thanks a lot, it works fine

you can also check the ON_BOOT=YES parameter in the interface configuration file

Yep, i tryed this but didn't work. I checked the files /etc/sysconfig/networking/profiles/default/ifcfg-eth1 and /etc/sysconfig/network-scripts/ifcfg-eth1 including the key but didnt work.
Only if i put the commands in /etc/rc.local works.

Regards

MMM, still not working... When I write route it shows me that the link is up, but when i try to make a ping it dont work. When i call service network restart the eth1 shows me a failure.

The comand i wrote in the file /etc/rc.local was: /sbin/ifconfig eth1 192.168.128.26 netmask 255.255.255.0

any solution?

The correct should be:You should also enable ip forwarding between the 2 nics:

Doesnt work yet
This is a ping
#ping 192.168.128.1
From 192.168.128.26 icmp_seq=1 Destination Host Unreachable
From 192.168.128.26 icmp_seq=2 Destination Host Unreachable
From 192.168.128.26 icmp_seq=3 Destination Host Unreachable

Sorry, but I've made a typo. The correct command for IP forwarding is:
Make sure that you don't have some kind of firewall that drops the packets from eth1

Well, this is the file /etc/rc.local of the server

#!/bin/sh
#
# This script will be executed *after* all the other init scripts.
# You can put your own initialization stuff in here if you don't
# want to do the full Sys V style init stuff.

touch /var/lock/subsys/local

# Afegit per Tecnics DEIC #
modprobe ipt_MASQUERADE
modprobe iptable_filter

sleep 15
/sbin/ifconfig vmnet1:1 192.168.0.1 netmask 255.255.255.0
/sbin/ifconfig eth1 192.168.128.1 netmask 255.255.255.0 up
/sbin/ifconfig eth2 192.168.129.1 netmask 255.255.255.0 up
echo 1 > /proc/sys/net/ipv4/ip_forward
/sbin/iptables -t nat -A POSTROUTING -s 192.168.0.0/24 -j MASQUERADE

What is your IP anyway? The one above or 192.168.128.26?

there are 26 machines this is the server 1, but i'm trying comunicating the pc 1 with the 26.
There is also a VLAN, this is a reason for the eth2 with another address

I'm not good in subnetting, but is n't that supposed to be

I dont know, this was not wrote by me this command existed before i wrote anything.

If you cannot contact the person you put that command in rc.local, I suggest you to configure your nics the way you want and then use a scipt to configure iptables according to your settings. Try quicktables which is an interactive script that lets you easily configure iptables rules.
