curious. very curious.
how
many hops are you from these machines? with /bin/ping you're not throwing any
options l assume.
i'd be
curious to see both a traceroute -n and traceroute -In. there might be
some qos rules somewhere if it's not a box on your subnet and reaches a layer3
device.

Thank you, Jerry -- attached are three png files
that show the effect of moving from multiping to /bin/ping at about
12:40. We had been having this problem for months. Many -- though
not all -- devices showed ping times that were several hundred milliseconds
higher than what /bin/ping would show from the same server. It was
almost definitely not a routing or other network problem.

Subject: RE: [snips-users] /bin/ping
vs. /usr/local/snips/bin/multiping
it's probably seeing the high rtt before you do. i
havent seen it send a false positive out before...

Yesterday, we moved ippingmon
from
/usr/local/snips/bin/multiping
to
/bin/ping
because the former was showing artificially
high round-trip times. Has anybody had this problem? Any
downside to using the system ping?
I am new to the list. Forgive me
if I am raising an RTFM sense.
