First, Corrina, thanks for the info. Because of my other ACL problems I
was totally confused
as to what was going on. I have, I think fixed these with a combination
of tools.
Second, my user ID is part of the Administrator group, but you must
specifically 'run as' Cygwin
to gain true Administrator privilege even from an Administrators group
ID in order for /bin/ping
to work in my tests. I'm sure you knew this Corinna, but others may not
have.
Third, I've changed the ping in my profile to use MS ping, and it works
fine. The parameters are
specified differently, but the exit codes work fine. I tried 'fping',
but its too noisy about having
to use the ICMP.dll, and the -i option (use the ICMP.dll as a first
choice rather than raw sockets)
seems not to work.
Now, I understand why 'ping' was missing for so long from Cygwin, and
why 'traceroute' has
never been a part of it. (Yes, I know about MS 'tracert'.)
Thank you, again, Corinna.
