Wireshark · Wireshark-users: [Wireshark-users] newbie question

["Krekan" <krekan@xxxxxxxxxxxx>]

    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
