       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

       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 server.

       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.
