Another 2 NIC question

marcob · 2005-03-29 18:25:28

So I've installed another NIC in my box, running 2.6.10.

The machine is an old Dell Gx1 with onboard NIC (3C905B.) I've installed a Network Everywhere card which, according to the documentation, I should treat as an Realtek 8139.

I've assigned IP's to both NIC's, and when I have just the first card hooked up, I can ping either IP or SSH into the machine via either IP. If I put the ethernet cable only to the 2nd NIC, I get nothing. Currently, I have both NIC's cabled up, but how I can I tell if they are working properly?

My ultimate goal is to install the bridge-utils package (I realize that when I do this I won't be assigning the IP's as I have them now.)

Here is the relevant info from rc.conf:

#
lo="lo 127.0.0.1"
eth0="eth0 192.168.0.22 netmask 255.255.255.0 broadcast 192.168.0.255"
eth1="eth1 192.168.0.23 netmask 255.255.255.0 broadcast 192.168.0.255"
INTERFACES=(lo eth0 eth1)

#
# Routes to start at boot-up (in this order)
# Declare each route then list in ROUTES
# (prefix a route in ROUTES with a ! to disable it)
#
gateway="default gw 192.168.0.1"
ROUTES=(gateway)

hmmm i'd def. make sure you alias them correctly... you can do something like this in modprobe.conf

alias 3c59x eth0
alias 8139too eth1

otherwise it's *possible* that they load up in the wrong order

You should use different subnets for the cards, otherwise it's unclear on which interface the data must be sent.

Use something like e.g. 192.168.0.22 and 192.168.1.22

phrakture · 2005-03-29 19:06:53

ah, yeah - good point... if you're going to bridge them, you need one side on the 192.168.0 subnet and the other on the 192.168.1 subnet in order to let them "talk"

OK, tried that, but no go at all on the 2nd NIC and IP now. Here's what i've got in rc.conf:

#
lo="lo 127.0.0.1"
eth0="eth0 192.168.0.22 netmask 255.255.255.0 broadcast 192.168.0.255"
eth1="eth1 192.168.1.23 netmask 255.255.255.0 broadcast 192.168.1.255"
INTERFACES=(lo eth0 eth1)

and in modprobe.conf

#
# /etc/modprobe.conf (for v2.6 kernels)
#
alias eth0 3c59x
alias eth1 8139too

# OSS Compatibility
install snd-pcm modprobe -i snd-pcm ; modprobe snd-pcm-oss ; true
install snd-seq modprobe -i snd-seq ; modprobe snd-seq-oss ; true

Can anybody tell if my netmasks are correct in rc.conf?

Also, a thought occured to me: I know our IP range (192.168.0.*) is defined in our Cisco router. Could it be I would have to define the second range in the router for this to work?

Thanks much again.

Probably yes... I think it's easier to do what you want immediately instead of this apparently useless configuration (two nics in the same box connected to the same network).
