Smokeping does not ping different subnets
 
Hello

I need help in regards to Smokeping pingin and populating graphs from different subnets.

The thing is, I have been asked to install Smokeping and to monitor traffic by pinging different AP/CPE. My employee is a small wireless ISP with about 2000 subscribers. He is using A class IP address and they are allocated to subscribers from the pool as well as to the AP/antennas/switches. The guy who owns the company says that they/clients are connected directly to the ISP and form one huge broadcast. I am still confused by this and the problem is when I try to run smokeping it pings only from one subnet e.g 10.0.106.254 / 255.255.255.0. Other IP addresses cannot ping from lets say 10.0.102.5 255.255.255.0 and therefore produces empty graph. To be honest I have been employed only for one week and I am confused with all this. The question how can I make smokeping to ping every IP address filled in inside configuration:
For example

+ Company

++ PIng
menu = Name of the location of the AP/CPE
title = Name ......
host = 10.0.100.2

++ and so on the list is too long

The Internet connection on the machine is when i type ifconfig I get
eth0 and its IP addres from the network to the internet/public IP add

eth1 is for LAN and it has 10.0.106.254 (that's why it only ping those AP in that subnet (e.g. 10.0.106.2, 10.0.106.7 etc...)

lo loopack interface

And if in the configuration he puts static Ip address for example from the above 10.0.106.254 it pings only those from that subnet, others not as I mentioned above.
How to fix this problem is it with Internet connection. We use Centos 5.3 and in network configuration when you click on Device tab and then on the list selected eth1 clicking twice the next window pops up and on the route tab he entered IP virtual interfaces from 10.0.100.254 255.255.255.0 to 10.0.128.254 255.255.255.0 range. For example 10.0.100.254 refers to all those in that subnet, 10.0.101.254 for all in this one and so on....til 10.0.128.254

I am sorry for not writing it in organised way but I am in hurry to solve this problem

Any advise and help is very much appreciated!
As I mentioned above, I need smokepign to produce graphs from all IP adresses AP to monitor the network.

Thank you in advance for your time and effort!!!
