For vat, you should be in close proximity to the UNIX box itself (usually the console is near the box), but you can run vat from any type of xterminal.
You can download vat and nv if they aren't already present on your system. Make vat and nv. They do not need to be installed, and you shouldn't need root privileges to run them.
If you happen to be on an HP and have an account on the UTDallas High Energy Physics farm, you can find an mbone/cu-seeme archive prebuilt for you on fester:
On fester, the nv and vat executables are in /home/grave1/joe/mbone/sd
nv -encoding cuseeme -recvGrey -xmitGrey IP_address port conf_ID e.g. nv -encoding cuseeme -recvGrey -xmitGrey flora.utdallas.edu 4444 10 (there is not really a reflector on this machine)Note that nv only understands conference id's 0 through 63.

There are two other formats which do not interoperate at present, although gsm has been encoded into the new alpha release of Maven, so it is probably a matter of time before it gets incorporated into CU-SeeMe.
gsm 17Kb/s GSM (80ms frames)
lpc4 9Kb/s Linear Predictive Coder (80ms frames)
Note that nv/vat ports used in the example aren't written in stone. They just happen to be the ports that the UTD and CSU reflectors are configured to use.
