With this application you can see which application is registered to use a port or, vice versa.
To perform a wildcard search, use the percentage sign (%). So typing "ftp%" will search for all items which start with "ftp". Or typing "2%" in the portst field will give you all ports starting with "2".
The database is stored on the SD and is updated online.
Before you can use this application, you will need to download a copy of the OUI database. To do that press "Menu->Update DB". I refresh and upload this database weekly.
For more information about port numbers see here: http://www.iana.org/assignments/port-numbers
Please email me with any bugs/problems/feature requests. I cannot reply to market comments which can make debugging difficult.
