LEGO

![lego.jpg](uploads/__moin_import__/attachments/LuisOntanon/lego.jpg "lego.jpg") </div> I'm a troubleshooter on GSM/UMTS networks working as a contractor for a major telecommunications manufacturer. I'm also a developer of Wireshark, usually "seen" as LEGO (which is a four letter acronym of my entire name: Luis Enrique Garcia Ontañón). In the past I've been an electrician, a pre-press specialist, a system administrator of a (very) small ISP, even an Operations "Manager" for a Mobile Operator. (Please note that I managed only machines... besides those I can barely manage myself wink ).
My e-mail is `<[email protected]>` . Please, do not contact me for issues regarding Wireshark development send your queries/suggestions to <[email protected]> instead.

I been a Wireshark contributor since 2003. As a Wireshark developer My principal contributions are:

  • display filter flexibility, my personal obsession smiley

    • an XML dissector that uses DTDs to create filter fields for XML documents

    • RADIUS dictionary support to create field filters for filtering the values of AVPS
