[PLUG] route delete errors

[VY]

Thanks for your reply.  I am a networking novice so maybe there is something
that I am doing wrong.
I just did this:

   sudo  route  del  -net  98.171.145.0/24  dev  eth0

and got back

   SIOCDELRT: No such process


I do not have a static route to that subnet in my routing table but I want
to cut off traffic to any of the 255 hosts in that subnet for a short period
of time -- hence I want to delete access to that network.
Am I using the wrong tool?
