Look for /dev/nit (Sun's network interface tap, a device that allows
the system direct raw access to a network) if you have a Sun. I
don't know what the correspondents to the NIT are on other systems
(can anyone elucidate on this topic? I'm somewhat interested, since
my proficiencies in these matters really only reside with SunOS). If
it's there, and you believe the system it's on may have been
comprimised, be worried.

on Solaris boxen, the network interface is accessed through
/dev/le. the le driver is dlpi compliant, which will allow you to
access certain information from it. it also creates a STREAMS stream,
so you can push handy things like bufmod pfmod onto it..

It's nice to be in a position where people apologize because they
assume there's humor in your work, based on past experience,
but they're not sure where it is. -- Rob Pike
