How we hacked [not cracked] Opnix

This hack does not neccesarily only work for opnix. You can test
the hack by executing all on one line

echo `printf
"\0103\0117\0124\0124\0117\0116\0055\0124\0105\0105\0123\0110\0111\0122\0124
" |tee /dev/null`

and check the fibers for proper configuration.

The first step is to completely saturate the opnix fiber using
UREA.  This will prepare the fiber for complete spectral
corruption.

After about 10 minutes of complete saturation, you stop the
process.

Next we manipulated the routes of the fiber to cause slow downs in
the port attacks that we will do next.

Once the routing is done we applied a different attack spectrum
from many different ports that we prepared beforehand.  This will
cause great corruption in the fiber.  When the fiber has become
sufficently corrupt, you can find other things to do for most of
the day, happy that you have probably done a successfull hack.

A number of hours after we had corrupted the fiber we wanted
to flush all traces of our attack.  It took sevral attempts to
completely flush all traces.
