I have a privat network at home. In the network are 2 WINDOWS XP computers, 1 Linux Suse (my router,getway and firewall) and 1 Linux rwdHat 9 computer. All computers work all right, but RedHat Linux computer gives me a Destination host unreachable, when I want to ping computers in my network. I have eth0 and eth1 network cards, that are active with static IP addresses. I'm new in Linux so I don't know, what to do.

-------------------------------------------------------------------

You have to add the route in your Redhat Machine.

route -n
and Add the route by using the cmd
route add -net default gw 192.1.1.1 eth0

-------------------------------------------------------------------

If you are using static IPs then you can simply add the IP and hostnames to /etc/hosts

I am in the process of setting up the network card on my dual boot RedHat 8 machine and am at a loss.
I am using DEC 21040 ethernet card that can ping itself, but cannot ping anything else. I know its not the cable or port because everything works fine on the windows side (go figure)
Whenever I try to ping a different machine, It times-out and has the message Destination host unreachable.

Anyway, here is the output of my ifcfg_eth0

Device=eth0
bootproto=none
broadcast=*.*.223.255
ipaddr=*.*.223.105
netmask=255.255.255.0
network=*.*.223.0
onboot=yes
userauth=no
peerdns=no
gateway=*.*.223.254
type=ethernet

-My dns server is *.*.226.1
-My ethernet card is using irq 11 and is not sharing with anything else.
-I think the driver my card is using is something called Tulip

-------------------------------------------------------------------

From the prompt, type: setup
Check under the firewall section that eth0 is a trusted device.

Also, at the prompt, type:ifconfig eth0 up

-------------------------------------------------------------------

Can you ping a IP address of a system?
Check your hosts file and see if all systems are listed. Also in root directory check/or update the .rhost file.
Also save your securetty file in /etc as securetty.ORG

-------------------------------------------------------------------

I think I am getting closer. I tried using setup and eth0 was not a trusted device. Every time I set it, after closing the box, it forgets the setting.
I cannot ping any machine except the card itself.
