   Lag/Packet loss simulator
  I'm looking for something to simulate internet conditions over a LAN.  I've taken a look at Dummynet, but the machines I'm on do not have a floppy drive.  Is there anything out there that somebody can recommend?Another way I've thought about doing it is sending my packets out to some server on the Internet that just sends them back to the other machine.  However it seems to me that the returning packets would have trouble getting through the firewall on the LAN (I don't have access to the router settings).  Thanks for your time.   
  Could you plug in a USB floppy drive? Or create an El Torito CD image of the floppy?   ;  There's a DirectPlay8 lag simulator which I tried to find for you on the net but not only couldn't I find it (okay, didn't look THAT hard) but I'm sure it only works with DPlay apps and thus may not be suitable for you.   ;  You can just write a simple proxy. I did it a while ago with UDP, but TCP is essentially the same. Just put in options to specify time delay between sending packets as you receive them, and a percentage that can be dropped entirely to simulate lost packets.At the very least, it will give you a little more socket experience.   ;  http://snad.ncsl.nist.gov/itg/nistnet/I'm building a box to run that right now, so I can't really see how well it fits your needscertainly having a software-based lag simulator so you can run [and debug!!!] server and client on the same machine would be very nice
