I will try to be more specific.
In my local network there's one machine that is the smokeping machine.
It has 2 nic's in it , one is connected to isp 1 (Telenet), the other to my
lan switch. On that lan switch , there is a connection with another
small router that is connected to isp 2 (Skynet).
Skynet and Telenet are the main internetproviders for Belgium.
I have 2 other machines which are placed in 2 different datacenters
to host websites.
What i want to do , is use the smokeping machine to verify the
connection to my 2 other server on both isp connections.
Why ? Because isp1 (Telenet) sometimes has a route problem to one
of my other servers. Then clients starting to call me because
theirs websites arent accesible from within the Telenet network.
So if i can use smokeping for this purpose , clients can check
themself if it is a connection problem with Telenet.
Thanks in advance for all your help.
