Analysing a capture file generated with
tcpdump version 3.9.8
libpcap version 0.9-PRE-CVS
captured on a
Linux 2.6.32.12-0.7-default x86_64
In a capture which has traffic from 192.168.0.xxx hosts, in IO Graphs window,
if a filter like "ip.src==192.168.0.181" is applied to Graph 1, and this host
did not produce any traffic (dead host or waiting for request), the IO Graph
will display the total traffic in the network, thus inducing in error.
Further confirmation was performed, applying the same criterion to the filter
in Wireshark's main window, which yielded no results.
Expected behaviour:
When the result is empty, no graph should be plotted, or a zero valued line
should be plotted at most.
