respond to.
It's a small app. If anyone else is interested then I might have a
look at the code (should be able to get a hold of the C/C++ source
code) and attempt to translate it to Transcript. Not too sure how
tight I can get the timings, but it should be accurate enough.
Luis,
I'm no expert in this area and I would love to learn that you can
write your own ping utility in Rev. I researched this a few days ago
in an attempt to do so. Creating the actual ICMP echo request
message isn't a big deal in Rev. I *think* the problem you would
have is when that message gets wrapped up in the IP Datagram
structure which I believe Rev does when you write to a socket. The
docs say that Rev's open socket command only uses "TCP" and "UDP" so
there doesn't seem to be a way to send data over a socket that
identifies itself as the ICMP protocol. I would think that ping
daemons would only watch for traffic that was send using the ICMP
protocol but I don't know.
