   Hello all, I am new to Ethereal. I would like to ask when I got file 
about 1 mb full of data captured how do I extract certain information such 
as password from those sniffed data. I run ethereal start to capture and 
when the size of file reaches limit which I set I get a file. The contents 
of this file I can only view in ethereal When I open it in regular viewer 
only bunch of binary data is seen. How can I filter for example ftp or pop 
Passwords?
Thanx
Krekan
