-q does not always quiet (Debian #661195) about fping

[schweikert]

I think that the code is correct and the documentation is misleading. -q suppresses the output for each probe. If you use -c4, you would see 4 lines for each host. With -q, you only see the final statistics per host, which is the sole output. Removing even that output doesn't make much sense: you can always redirect to /dev/null, if you want to ping, but are not interested in the results.

... which is not the case if the pinged hosts are in the same LAN and
therefore that's the bug:

$ fping -q -c4 kiva1 kiva2 kiva3 kiva4 kiva5 kiva6 kiva7

kiva3 : xmt/rcv/%loss = 4/4/0%, min/avg/max = 0.12/0.14/0.17

kiva5 : xmt/rcv/%loss = 4/4/0%, min/avg/max = 0.14/0.15/0.19
kiva6 : xmt/rcv/%loss = 4/4/0%, min/avg/max = 0.04/0.04/0.07
kiva7 : xmt/rcv/%loss = 4/0/100%

The issue are the "ICMP Host Unreachable" lines, not the
"xmt/rcv/%loss" lines. The "ICMP Host Unreachable" lines should not
happen with -q.

So please suppress all "ICMP Host Unreachable" lines if -q is given.

The ICMP Host Unreachable lines are a separate issue, which was recently fixed (#1)

This issue still exists for fedora. Please investigate.
