Ethereal-users: RE: [ethereal-users] help please.
You may be having the same confusion I had in using the Ethereal Filter setup window- It is not what I would call intuitive.
1. Bring up the Ethereal Filters window
2. Enter a Name- overwrite whatever is there if necessary- Ex Port20K Only
3. Enter the filter string- Ex tcp.port==20000
4. Now press New button
5. Press Save ? Not sure but just in case.
Now you have a filter named Port20K Only
The trick is to fill in the blanks and then hit New- opposite of what I expected.

thanx Guy, thanx John for the prompt response.
Guy, What I mean to say is -- I m not able to use the Filter Preferences
in the pop-down menu of ethereal GUI. I am not able to create a new filter
from that option. However, I am able to use filters using the pane below
the hex dump pane.
regards,
Subramanian
