hello,
nothing changed.. ping tests are showing red/flapping, these are the only
tests i run..
all hosts with real ips are green.
the strange is that i run a ping test for hours, and says 0% packet loss,
but xymon keeps the host in ref/flapping condition..
--- 10.122.2.1 ping statistics ---
104332 packets transmitted, 104261 received, 0% packet loss, time
104457908ms
rtt min/avg/max/mdev = 70.537/74.760/110.730/1.034 ms

This could be a number of things. The obvious question is what has changed
(that you can see)? Any new routers, changes to the VPN setup? What tests
are showing red/flapping? Are all tests for these affected hosts
red/flapping? You say it is only those systems with a private network, do
you have others that aren't a private network through the same VPN that are
OK? What is happening at the VPN gateways at each end, can you run tcpdump
on these systems to find any patterns? If tests are flapping, that means
some packets are getting through, you should be able to see this on the
gateways.
hope this helps, Phil

hello all,
the last 4-5 days, i have a major problem with my xymon server.
I run it for several years, monitoring connectivity on misc servers on my
local network.
Xymon server is connected to my local network via a VPN, and it seems that
the problem is with the computers that have a private ip (10.xx.xx.xx).
when i restart xymon, everything seems ok for a few minutes.
after this, all become red and i have a "flapping status" warning.
i tried to change values in tasks.cfg with no result.
i unistalled/installed xymon, with no result.
my configuration is very close to the default, except hosts.cfg of course.
i tried to ping for hours a host on my localnet, from xymon server,
successfully, with no packet lost..
can anyone help me with this ?
