[hobbit] Problems with hobbitping when the Network is unreachable (BUG)

[Hubbard, Greg L]

Try fping.  I think Henrik has not had time to fix problems with
hobbitping.  It may be one of those "it seemed a good idea at the time"
things...

	Hi Henrik, 

	I rebooted my hobbit server and it lost its default gateway,
unbeknown to me.  The only symptoms of something wrong was a purple in a
network test is was supposed to be doing and a purple in the server's
bbtest column.  Now, I reckon one or other or both of these should have
both gone red and not purple, and the reason that they did not is due to
hobbitping going into a spin:  what looks like a fairly tight loop.
Hobbitping was using quite a lot of CPU (I saw it at well over 30%) and
server/tmp/ping-stdout.1407 was empty but server/tmp/ping-stderr.5499
was getting many (about 60) "Failed to send ICMP packet: Network is
unreachable" written to it every second.  I reckon this message should
have been in the report of the connection test it was trying to do
(although you could argue that the colour should be clear and not red,
since one doesn't want dozens of alarms for a problem that is actually
on the network-test server).  It took me some time to figure out what
was wrong because hobbit didn't report this problem in any of its logs
(presumably because hobbitping never returned and so bbtest-net never
returned its status) (and hobbitd_client stopped working for some other
reason (core dump) yesterday and, although restarted, remains not
reporting with nothing in the logs).

	Kind regards, 

	Sebastian
