[TriLUG] throttling bandwidth in a test environment

[Greg Brown]

I did this once at Oculan.. sort of.  I had two ethernet segments with 
a "wan" in the middle... here's how I did it.

Machine 1:  ethernet port 192.168.13.1 network 192.168.13.0/24
                       serial port 192.168.14.1
Machine 2:  serial port 192.168.14.2
                       ethernet port 192.168.16.1 network 192.168.16.0/24

I connected the serial ports via a null modem cable and, if memory 
serves, I used ppp to connected them together.  Or was it slip?  No, it 
was slip.  I think this is the how-to webpage I used:

http://www.dbaoncall.net/references/ht_connect_2pc.html

That's about all I can recall, other than it worked.  Hotgrits on the 
IRC channel might be able to help out with this, as I recall he was a 
wealth of knowledge regarding serial communication and linux.
