LEGO

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 ).

My e-mail is <luis@ontanon.org> . Please, do not contact me for issues regarding Wireshark development send your queries/suggestions to wireshark-dev@wireshark.org instead.

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

SIGTRAN/UMTS/GSM enhancements, my "normal" job
- H.248 package decoding
- H.248 context tracking
- SCCP connection tracking
- ALCAP (Q.AAL2) filter enhancements, and call tracking
- IuUP dissector
- SCTP TSN tracking
- added H.248, BSSAP and RANAP to the VoIP Calls tap
display filter flexibility, my personal obsession
- 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
- DIAMETER dictionary support, twice like above
- SNMP SMI based filtering, that create field filters from MIBs for filtering the values of SNMP variables and indexes
User Enhancement additions,
- Lua bindings
- Mate Meta Analysis Tracing Engine
- Display Filter Macros
Other things
- tektronix K12xx-K15 .rf5 and text file support
- SNMPv3 decryption
- editcap's -A and -B options to slice files from a time to another time
Things that only developers use
- I followed RonnieSahlberg when he created emem by writing the ep_ and se_ helpers (ep_strdup, se_strdup_printf, ep_memdup, etc.)
- UATs user editable tables for user preferences
