I.e., the URL I mentioned:
    http://windump.polito.it/docs/manual.htm
didn't work in your browser?

To quote my previous reply:
    Note that this is a sample command line - "tcpdump" is the command, and
    "host sundown" are the arguments to the command, giving the filter.  You
    would use just "host sundown" with Ethereal - you would *not* put
    "tcpdump" in there.

That's because it's not valid.
You could do
    ip src host xxx.xxx.xxx.xxx or ip dst host xxx.xxx.xxx.xxx
("src" and "dst" are qualifiers for "host", so they come before "host"), but
    ip host xxx.xxx.xxx.xxx
is sufficient (an unqualified "host" means "source or destination host":
              dst host host
                     True  if  the  IPv4/v6 destination field of the
packet is
                     host, which may be either an address or a name.
              src host host
                     True if the IPv4/v6 source field of the packet is host.
              host host
                     True if either the IPv4/v6 source or destination  of 
the
                     packet is host. ...
