how do I access interface details from inside perl ?

Hi !

I know that this is a little bit off-topic but the perl folks couldn't 
answer this. I'd like to get information about incoming and outgoing 
packets or bytes, like e.g. netstat or ifconfig shows. But I don't want 
to call an external program.
