Aldo,
You English is better than my Spanish! If I understand you, you
want to filter out all traffic except for a specific host, or group of
hosts. You can do this with the "--filter-expression" option on the
command line or set the filter from the user interface. From the man page:
-B | --filter-expression
Filters allows the user to restrict the traffic seen by ntop on
just
about any imaginable item.
The filter expression is set at run time by this parameter, but it
may
be changed during the ntop run on the Admin | Change Filter web
page.
The basic format is -B filter , where the quotes are REQUIRED
The syntax of the filter expression uses the same BPF (Berkeley
Packet
Filter) expressions used by other packages such as tcpdump
For instance, suppose you are interested only in the traffic
gener-
ated/received by the host jake.unipi.it. ntop can then be
started
with the following filter:
ntop -B src host jake.unipi.it or dst host jake.unipi.it
or in shorthand:
ntop -B host jake.unipi.it or host jake.unipi.it
See the �?expression�? section of the tcpdump man page - usually
avail-
able at http://www.tcpdump.org/tcpdump_man.html - for further
informa-
tion and the best quick guide to BPF filters currently available.
WARNING: If you are using complex filter expressions, especially
those
with =s or meaningful spaces in them, be sure and use the long
option
format, --filter-expression="xxxx" and not -B "xxxx".
