Moreover, from the sound of things, you can only ping 100 times as root, which may not be enough (POST on a UE450 can take forever :-)). Then there's ping's invaluable-ness when dealing with crappy 3com linkswitches (which lose ARP entries if it hasn't seen traffic from a machine for a while). Being root to do that is less than ideal, as well. I don't see unlimited pinging being a problem as long as Joe User can't use the -f or -s flags. -- Brian Cully <shmit@erols.com> ``And when one of our comrades was taken prisoner, blindfolded, hung upside-down, shot, and burned, we thought to ourselves, `These are the best experiences of our lives''' -Pathology (Joe Frank, Somewhere Out There)
