Re: a network simulator in perl

[rpc]

I think this would be pretty easy to do with Linux's tuntap device: a userland interface to ethernet interfaces.
This allows you to use a filehandle (/dev/tunX) to write raw packets to the wire.
You could have a Perl daemon that creates/maintains several nodes on your network, each listening on a separate IP..or something :)

Relevant dox can be found in /usr/src/linux/Documentation/network/tuntap.txt

oh no no :)

i was talking about a network simulator purely for fun, not utilizing any networking hardware or making any actual connections over any real networks... kind of like the galaxy game, only stripped down... the planets are nodes, and wires can be strung between the planets, carrying cargo (bits), and you can play with the system, to see how it reacts to new nodes, new connections, or knocking out connections in certain places ...

i love simulators... like simcity... :)
