need a link on multple network interface simulator

kapsikum · 02-13-2006, 10:40 PM

hi,

can anybody please provide me any information regarding where can i download a multiple network interface simulation tool. I need to test a router through a host, with single NIC, on which our tool will run and fire different kinds of traffic to the router through different interfaces simulated.

I am using ubuntu linux.

Thanks in advance,

Will the dummy driver in the kernel do what you need?

Quote:

CONFIG_DUMMY:
This is essentially a bit-bucket device (i.e. traffic you send to
this device is consigned into oblivion) with a configurable IP
address. It is most commonly used in order to make your currently
inactive SLIP address seem like a real address for local programs.
If you use SLIP or PPP, you might want to say Y here. Since this
thing often comes in handy, the default is Y. It won't enlarge your
kernel either. What a deal. Read about it in the Network
Administrator's Guide, available from
<http://www.tldp.org/docs.html#guide>.

To compile this driver as a module, choose M here: the module
will be called dummy. If you want to use more than one dummy
device at a time, you need to compile this driver as a module.
Instead of 'dummy', the devices will then be called 'dummy0',
'dummy1' etc.
