	I appreciate your reply.

	I actually have smokeping running on both ends, but I'm looking
for something that can run in an xterm while I'm writing email and I
can see it actually pinging live. The others are snapshots of the
network, not real time. If it pings every 5 minutes, for 20 seconds,
and the next 270 seconds the network is down, then comes back, the
utilities are going to show 100% up. Unless the intermittent
issue happens during the polling cycle, we won't see it. I'm running
into the problem of the WISP seeing the graphing show 100% up, while
I'm sitting here with 64 second chunks of network disappearing. I
also can't prove its ONLY my site happening, since I am only at this
one site. I wanted something that I could leave running in a "screen"
on one of his DD-WRT installed Buffalo (SIGH... That lawsuit sucks)
routers.
