[smokeping-users] Failed ping

[Eric Brander]

I've been using Smokeping for several years now but I just recently
started having a problem pinging a remote site. There are 4 IP
addresses at this site and I'm able to ping and fping them all from
the command line. However Smokeping has trouble pinging one of them -
and it's not always the same one. Sometimes it will change which one
it can't reach after just restarting, but only after it's been running
for a while.

I'm running fping every 60 seconds, with 10 56-byte pings.

Tcpdump shows the first one of those pings recieve a reply but then
the rest never get a reply:
