UNIX for Dummies Questions & Answers

Hey all,

I got a Ultra 60 and I'm going to put a quad fast ethernet card into it, also I have a NAS with dual ethernet ports. I'm going to setup the Ultra 60 as a gateway to the NAS.

Is it possible to setup 2 ports on the quad fast ethernet card to talk to the 2 ports on the NAS? Both using the same IP and the computer thinking that it is all one port not 2?

OR

Is it possible to setup the Ultra 60 and NAS so that one port is used for incoming data and the other for out going data. Thus having a 100Mbit connection each way to and from the NAS to the Ultra 60?

If either of these two ways or both are possible where cas I find some documentation on how to set it all up?

Thanks.


Oh yeah the Ultra 60 will be running Solaris 8 and the NAS well that has some Micro version (kernel) of linux (So I have been told).

You can set up two ports (one for incoming and one for outgoing) between the two systems.

Here is how:

2 servers - S and N.
2 ports on each - I and O.

On S, set port I to 172.16.1.10 and port O to 172.16.1.20
Add a route for 172.16.x.x to 172.16.1.20. Adding the route will be setting that port to be outbound (any traffic for 172.16.x.x goes out that port).

Set the IP of the I port to be the known IP for the system by adding it to DNS or in the /etc/hosts of the other server(s). Then all incoming traffic should hit the I port.

Do the same (if possible) on the N server.

The only thing I don't know is if any software will have a problem with it since the 'stream' will be coming back from a different IP.

I know SUN used to have a software product to take the 4 ports of a qfe card and assign the same IP (to get 200 incoming and 200 outgoing )but I don't think it can be done with normal commands. Sorry, don't remember much more about it.

The software is Sun Trunk.

It requires you to have a network switch that supports the trunking protocol. check the docs for supported switches.. we are using a quad fast ether with all for ports acting as one for our b backup solution. Works great!

check it out!
