Unix - Ping Host graph -nan

[StratosGreece]

Hi all,
I am totally new to linux, and I am trying to set cacti under ubuntu…
I followed this guide http://www.goldfisch.at/knowwiki/howtos/cacti
After I login to cacti I can get graphs from my local host and Cisco 876.
BUT when I am trying to create a graph with Unix - Ping Host I get empty graphs (with –nan, even if the status of the machine I try to monitor is up)…what am I doing wrong?
Could anybody give me an installation guide that he/she is sure that it works…
Thank you all

I am sending you some debug

#my machine responts to ICMP
Ping Results
ICMP Ping Success (25.234 ms)

#This is the debug of ping latency that i get an empty graph…you can see that RRDTool says OK
