Hi Luca, I have done some more analysis on this problem with the latest svn release and this is what I have found:
I have a subnet 10.0.128.0/17. I have computer A at 10.0.129.91, computer B at 10.0.133.88 (running ntopng), computer C at 10.0.133.87 and computer D at 10.0.133.177. They are connected together via GigaBit ethernet on a lan with other devices. I start a listener nc process on 10.0.133.88 as follows: nc -kl 5555 >/dev/null 2>&1 If start a sender process on either computer C or computer D using nc 10.0.133.88 5555 </dev/zero Then on the Top Flow Talkers window whole graph is 10.0.133.87 - 10.0.133.88 or 10.0.133.177 - 10.0.133.88 depending on which one I am sending from - This is exactly what I would expect. But is I send from 10.0.129.91, even though my thruput is still at 600+mbs, I get various units showing up on the Top Flow Talkers graph, and maybe periodically I will see 10.0.129.91 - 10.0.133.88 even though on the host list screen they show up as the top two. Is there something that is looking at peers that is only considering a /24 prefix? Regards, Steve On 09/12/2013 01:48 PM, Steve Clark wrote:
Hi Luca, Either I don't understand what the Top Flow Talkers graph means on the Dashboard or something is broken. I have on the box I am running ntopng running (10.0.133.88) nc -kl 5555 >/dev/null 2>&1 on another box (10.0.129.91) I have nc 10.0.133.88 5555 </dev/zero In the bandwidth meter I see about 680 mbs being shown but I seldom see the top flow talkers graph show 10.0.129.91 - 10.0.133.88. I would expect this to be a wide band and showing up all the time. Am I wrong in my understanding. If I go to the host list I see the two above IPs showing as the first two in the list. 10.0.133.88 Local 10.0.133.88 8 min, 55 sec SentRcvd 653.39 Mbit 42.62 GB 10.0.129.91 Local 10.0.129.91 8 min, 55 sec SentRcvd 653.39 Mbit 42.62 GB -- Stephen Clark *NetWolves* Director of Technology Phone: 813-579-3200 Fax: 813-882-0209 Email: [email protected] http://www.netwolves.com _______________________________________________ Ntop-dev mailing list [email protected] http://listgateway.unipi.it/mailman/listinfo/ntop-dev
