A similar question was asked by in August -- search the archives for subject
for the whole thread. A couple of quick summaries:
Forget ping - we were said it requires root access on Unix, so it is not
in-there. Many ppl requested it. I thought that Rebol could check for rights
somehow, but I can't know Rebol internals of course.
Or just buy /Pro version and use shell access to call it.
The ICMP protocol is not a user protocol, so REBOL does not handle it; if
you want more detailed reasons, or just want to complain about it, please
Both TCP and UDP provide standard echo ports. That service is
usually disabled on most servers (for obvious reasons), but
servers will have IMP echo disabled too in most cases; so, you
may want to try something like:
>> port: open/no-wait tcp://target.machine:7
>> insert port "PING"
>> copy port
>> close port
