I was pleased to be asked to do a last minute fill-in presentation for
ClueCon 2006. Owl River was present at Brian West's request, to provide
coverage
as to E-164 public ENUM registry,
CA Cert public, no-cost Certificate
Authority [the foregoing two having sponsored some of our travel and lodging
costs -- thanks], and the CentOS
community rebuild Enterprise Linux distribution, and RPM Package Manager.
Some present had missed the PNAEVL's announcement on July 13
2006 of their intent to be the Enterprise Linux for
telecomm; it seems to be a shot across the Carrier Grade Linux'
bow ...
As our presentation was added 'on the fly' to the schedule,
we built a presentation with a set of
pre-opened web-pages, to walk and talk through, and a 'sniffing' console
running tcpdump watching the traffic on ports 80 and 443 of a
webserver at: www.owlriver.org
containing my late mother-in-law's lasagna recipe; the goal was to
demonstrate how a certificate (free) from CACert permits us to secure a
connection.
Finally, we looked through an OpenVPN tunnel back
content in an otherwise non-accessible and non-routed network segment.
OpenVPN has application to securing SIP style content, as UDP will happily
route through such encryption protected tunnels; OpenVPN has 'hooks' to use
certificate authority counter-signed keying.
We will be adding a tcpdump trace, duly annotated, and some of the
commentary to this page from our talk. This placeholder page has been buit
through the 'wet noodle' bandwidth which resulted after the poor Cisco
switch at the hotel venue was melted down by conference attendees.
