[NTLUG:Discuss] Networking: USB to USB or Firewire to Firewire?

[Jack Snodgrass]

I think that I have seen both approaches done on 
Windows. You'd think that it's been done on Linux 
before but I didn't find any info on it. 

Say that I have two linux boxes. Each has a spare
USB port and a spare Firewire port. 

Can I cable these two boxes up directly and 
transfer files between them? 

I know that I can use a pair of USB ethernet 
adapters and a cross over cable, but I want to 
use something like a cross over cable between 
the two machines and avoid getting two NICs. 

I read that a Windows program would let you 
do 400MBit between 2 Firewire boxes. USB2 
is supposed to be fast too. 

Thanks.
