Package: fping
Version: 2.4b2-to-ipv6-15
Followup-For: Bug #308695
fping removes any hosts which it fails to ping from the internal list.
If the host on which fping is running drops the default route and all
ping destinations have no route, fping terminates. But if there
is at least one host still reachable (i.e. due a connected route), fping
will proceed pinging only those remainig hosts (even if the route comes back
again). In the following example 172.31.1.1 is on a connected route:

This breaks long time monitoring when fping is running continuous. This
could be fixed by the following patch:
--- fping-2.4b2-to-ipv6/fping.c 2008-09-29 12:32:32.000000000 +0200
+++ fping-2.4b2-to-ipv6.fix/fping.c 2008-09-29 12:25:15.937404006
