2 cards 2 networks question

Hi,

We have a collection of machines on our corporate network (100mbit) and
I want to add a second card to selected machines (1Gbit) and connect
them together via a switch , assign a 2nd IP address (10.0.0.x)and
hostname, forming a private network, so that they can interact at high
speed independed of our corporate network. The coporate network would
provide general access to the machines, private comunication would be
via the private network.


Corp NET (100Mbit) Private NET
(1000mbit)
|----(Box_A) eth0(192.162.2.1) machine eth1(A)
(10.0.0.1/255.255.255.0)--|
|
|
| ---(Box_B) eth0(192.162.2.2) machine eth1(B)
(10.0.0.2/255.255.255.0)--|
|
| -- (Box_C) eth0 machine
|

Box_X is corporate name, X is private name..Addresses are dummy


My hope would be that if I went (example) telnet Box_B from Box_A it
would go via the coporate network, but if I went telent B from Box_A it
would go via the private network. The coporate nameservice would be via
the corp. DNS server. for the private network it would be via the hosts
tables of A and B.
The gateway is set to the coporate one (192.162.2.254)


Problem is it doesn't work..... where have I gone wrong. :-( How would
it know which card to go out....??? What am I missing???

Thanks in advance

Can you be even a teeny bit more specific? Look back at similar threads
in this group, see what information was required, then post it for your
situation, along with a description of *what* it is that "doesn't work".

Some questions:
1. What does ifconfig display on all machines?
2. Can you ping all network interfaces locally?
3. How do the routing tables look like?

It knows which card to use by means of route table.
What give you:
$ netstat -rn ?
$ ifconfig eth0 up 192.168.2.1 netmask 255.255.255.0 gw 192.168.2.254
$ ifconfig eth1 up 10.1.0.1 netmask 255.255.255.255.0

Hope this help,

Check your orders file. You need to check hosts file
before DNS, check your incomplete name settings,
is B being rewritten as Box_B before looking up.
make shure you have a network route for private network.

Set up dns services on private network, and look up all names from there,
then that dns could forward lookups to company DNS.
