I believe those are ethernet packets, and perhaps im on crack but I was under the impression that ethernet packets couldnt exceed 1500 bytes. I'll have to check my references tommorow at work. In any case its undenyable that with 1514 X-window packets I am unable to communicate with some remote displays (probably due to a router between here and there choking on the large packet size) if I drop it to 1480 I have no problems what so ever. -Crh Charles Henrich Michigan State University henrich@msu.edu http://pilot.msu.edu/~henrich
