[smokeping-users] Re: question on probe timing

[Dan Tucny]

Fping will by default send one ping every 25 milliseconds (40 packets
per second, 84byte packets, 3360 bytes per second) and will wait 1
second between pings to the same host. From that, 40 hosts would take
roughly 20 seconds, 80 would take about 40 seconds. Depending on how
many hosts you are needing to check and the size of your own line you
may need to increase the rates, but 33.6kbit/second on default settings
is pretty unlikely to get anywhere near DoS'ing yourself.

Subject: [smokeping-users] question on probe timing


I've just begun using SmokePing to assist in quantifying the
latency to some of the other branches at my company (connected
via frame-relay).

I am concerned about DoS'ing myself by sending out probes
to all the branches at the same time (or in rapid succession).

Is this even a valid concern? Is there a way to limit the
rate at which the pings are sent out?

Thanks,
Andy
