Hello from México

I´m capturing a data network traffic with TCPdump, I want to capture only the time and the MAC addresses of the packets. I can do that and, I can plot the Total MAC addresses (packets) per second with a "for cicle" , But I need to plot each MAC address in only graph.

 I have this Matrix after read de data, I have two MAC addresses and I can plot the total MAC addresses per second, and I have this graph,  but I want to plot the total mac addresses per second of  this addresses 001495702619 and 1C659D0C29B9, bone have two graphics with each MAC address.

I include the Matrix and the graph.

How Could I do that?

在 MATLAB Online 中打开

[u,a,b] = unique(YourData(:,2));
packets1 = YourData(b==1,1);
packets2 = Yourdata(b==2,1);

then you can apply your per-second counting code to packets1 and packets2; you could plot the results both on a single graph or each on their own graph according to your preferences.
