Experience in Internet buildingJanuary 1993 - Suryono (Texas) install
a packet radio 1200bps to LAPAN.LAPAN 1200bps to BPPT & Internet
64Kbps.286 PC as gateway! to connect the
whole ITB campus.Software NOS (running on DOS) as
gateway.

ITB in 1995
Telkom Leased Line at 14.4KbpsRISTI-Telkom to BPPT 64Kbps.ITB uses FreeBSD (UNIX) as Router &
Server.For the first time ITB sees Web in
Internet.ITB learns to build a campus network
(how to handle the lightning).
