       cutter - cut tcp/ip connections


       cutter ipaddress1 [ port1 [ ipaddress2 [ port2  ]  ]  ]


       Cutter is an open source program that allows Linux firewall administrators to abort TCP/IP
       connections routed over the firewall or router on which it is run. it is not  designed  to
       work  on the systems hosting the server or client using the connection, it only works on a
       linux firewall or router over which the connection is made, and it must be run by the root
       user of the firewall.


       Cutter  has  been  designed for use as a administrators tool for Linux firewalls. It's use
       (as is, or modified) for any other purpose is not sanctioned by the author. So  -  do  not
       use this tool as a parachute, or to dry your cat, chill meat, answer your phone, drive you
       car, teach your kids to read or attack other people's computer systems or networks.

       This software has been  designed  for  legal  and  appropriate  use  by  network  security
       administrators  and  the  like.  It  has  been  written as part of a larger Linux firewall
       project, targeting at controlling traffic from peer-to-peer software such as Kazaa,  iMesh
       and  others  into and out of a private network. It is not designed as a tool for malicious
       use and the author in no way sanctions such use.

       Users of the software should be aware that it's actions  are  easily  detectable  using  a
       number  of readily available network monitoring tools, and it makes no attempt to disguise
       it's actions. Malicious use of "cutter" could result in a jail sentence  in  a  number  of
       countries around the world.

       The  author  is  not  responsible  for  the  results  of using this software or documented
       technique(whether in it's original form, or modified). It is provided "as is" in the  hope
       that it will be useful, but no guarantees are made about it's use.


       Cutter can be called using one of the following four syntaxes.

       cutter ip-address


              Cuts  all  connections  passing  through  the  firewall  between  any  ports on the
              specified ip-address (either a "private" or "public" address) and any other  hosts.
              This can be used to close down all incoming connections to a particular server, all
              outgoing connections from a particular client or  all  outgoing  connections  to  a

       cutter ip-address port

              cutter 80

              Cuts all connections to or from the specified ip-address/port pair. This allows the
              user to be a little more specific than the previous example and allows targeting of
              specific services on specific hosts.

       cutter ip-address-1 port-1 ip-address-2

              cutter 22

              Cuts  all connections between ip-address-2 and ip-address-1/port-1. This allows the
              user to cut connections between a specified "client" and a particular service on  a
              specified  host.  Our  example  closes  host's SSH connection to server

       cutter ip-address-1 port-1 ip-address-2 port-2

              cutter 22 32451

              Cuts the specific connection between the two ip/port number pairs given.


       Cutter 1.04 should be considered EXPERIMENTAL.  The author is releasing a tool that  works
       on  the systems which he has access to (namely: IPCop and RedHat Linux), and he is seeking
       input on it's use on other systems, ideas for improvement, offers of sponsorship - etc.
