2nd NIC how do I configure ?


Hi,
Just a simple network question really. Sorry but could not find the answer to any tutorial.
I've got a spare NIC which I installed on my linux system which is working fine through a LAN (gateway 192.168.0.1, eth0 192.168.0.3)
How do I configure the new NIC eth1 so I can connect an old win 98 machine through this one ? Thanks.

What are you trying to accomplish?

Are you trying to share the internet connection of your linux machine with your windows 98 machine?

or

Do you just need help deciding where to setup the nic?

I'm trying to share my internet connection from my linux with the old windows.
Not sure if I should allocate a static IP address to the windows machine or leave it as DHCP enabled. And if so how do I configure eth1 (what IP address, route etc)
Thanks in advance

To bring up the 2nd (eth1 NIC):

ifconfig eth1 <ip address> netmask <netmask> broadcast <broadcast> up.

That's how you bring up the 2nd nic online. As long as the 2nd nic is in the same subnet as your win98 box, you should be able to connect to it just fine.

I have done that now so ifconfig gives me this:
eth0 inet addr:192.168.0.3 Bcast:192.168.0.255 Mask:255.255.255.0
eth1 inet addr:192.168.0.10 Bcast:192.168.0.255 Mask:255.255.255.0
Monitoring the network now gives me the option to select eth1 but only send traffic is seen (very little)
Something is still not right
I have also noticed the lights at the back of eth1 NIC are off. Does that mean the card is not installed properly ?
Thanks

If you are managing to give our NIC's IP addresses they should be installed ok. Type ifconfig -a and check that they are both in there with the correct IP addresses.

Yeh,
both NICs are there on ifconfig -a
Now, the only thing I haven't tried is the crossover cat5

give your windows machine a static ip and try pinging your linux box. you should be able to get a response at least.

Should eth0 and eth1 be on the same subnet mask or different ?
When I tried :
eth0: 192.168.0.3 netmask 255.255.255.0 broadcast 192.168.0.255
eth1: 192.168.0.30 netmask 255.255.255.224 broadcast 192.168.0.255
I lost connectivity to the outside world. No DNS server IPs seen.
When I brought eth1 down, all is normal again.
I guess I will have to give some comand for DNS servers, but don't know how, and if required for both eth0 & eth1
Will get there eventually !
Thanks

Problem solved,

Here is what I did.

eth0 192.168.0.3 mask 255.255.255.0
eth1 192.168.1.1 mask 255.255.255.0
on win 98:
static 192.168.1.2 mask 255.255.255.0
gateway 192.168.0.3
dns host 192.168.1.1
Thanks
