vpn mystery
i've got two remote subnets connected ala 'virtual private
network' through the internet. but there's some oddness going
on.
i'm using debian potato and the "ip tunnel add"/"ifconfig" tools
to set up the tunnel.
anybody around these parts have any experience with VPN this
way? i'd love to pick your brain for a moment or two, if you can
help me out...

DEBIAN NEWBIE TIP #19 from Dave Sherohman <esper@sherohman.org>
:
How do you determine WHICH NETWORK SERVICES ARE OPEN (active)?
Try "netstat -a | grep LISTEN". To see numeric values (instead
of the common names for services using a particular port) then
try "netstat -na" instead. For more info, look at "man netstat".
Also try "lsof -i" as root. "man lsof" for details.
