Re: [ts-7000] ts-7800 how do I make 4 (at least 2) identical network stacks?

[Eric Robishaw <>]

Maybe this is too simple... But why not just use Udp broadcasting, let each device receive all the messages and filter out what they don't need.  No need for special routing, etc..

The mac address can be easily found. The problem here is that Linux won't accept the same sub network on two different interfaces and the IPs of the remote boxes can't be changed. This has to be handled by routing below the interface level, or raw Ethernet.

Hi,



I've been following along in the background, reading
about half of

what's been said, and understanding less, but I
haven't seen anyone

suggest this...



Can you use ARP to an advantage here? The normal way
I've used ARP is

when we have a terminal server which has not yet been
configured... you

arp the mac address to a hostname on your PC, then connect
to the still

unconfigured box, and configure it. Your computer knows how
to find

that remote box by it's mac address, even if the remote
box doesn't yet

know what it's IP address is yet. Can we do that here?



Imagine this implementation... You have 4 boxes which all
want to have

the same IP address, but they all have different MAC
addresses, which

I'll refer to MAC1, MAC2, etc. On your TS7800 you have
a plain old

single interface eth0 with the address of your choice, and a
typical

socket listener. When a client connects, you accept(), like
you

normally would. It's been years since I've dealt
with the addr structs

the sockets use, but I'm thinking there is a way to tie
a mac address to

the socket, or lacking that use arp. At that point your
file descriptor

is working correctly and you don't care about IP
addresses, you are just

talking back and forth op that open socket.



Maybe I've missed some critical detail, but the point is
when you use

mac addresses, and/or hostnames, and you don't worry
about addresses any

more.



Good luck,

Joe
