Bing has not worked for me for many versions.  bing 1.1 works fine, but
1.3 in all versions that I've tried for years always fails.  Here's the
log from a typical example ("gw" is the router on the local network).
It always fails with the error "not enough hosts were found to perform
the bandwidth analysis".

# bing localhost gw

What happens if you use bing 192.168.7.123 192.168.7.1

where .1 is your gw and .123 your own ipv4 in this subnet instead of
localhost

or at least messages surrounding some bandwidth information.  The dots
