RTCHK (ROUTING_CHECK) -- Test traffic between adjacent routers.
usage:  RTCHK [-N net.node_id] [-DEV[ICE] dev-name [dev-num]] [-S n]
                                        [-DAT|-NODAT]


FORMAT

  RTCHK [options]


  RTCHK performs a simple test to verify that the router is able to pass packets
  to and from an adjacent router.  RTCHK is for use in a DOMAIN internet.

  Use the -DEVICE option to specify a network controller to test. You must  give
  a  device  type (e.g. RING, IIC) to the device option. The RTSVC program, with
  no command line options, shows you which network devices your node has.

  Older versions of RTCHK used a different command line syntax  to  specify  the
  type  of  network hardware checked. The old command line options still work in
  RTCHK version 9.6, but are no longer supported.

  For more information on RTCHK, see Managing DOMAIN Internets.


OPTIONS

  Default options are indicated by "(D)."

  -N net.node_id
                     Test  packet  transmission  to and from the specified node.
                     The network ID 'net' must be  a  network  that  the  router
                     touches.  If  you  use  -N without -DEV, you must specify a
                     net.node_id.  If you use -N with  -DEV,  you  must  specify
                     only the node_id, without the network number.

  -DEV[ICE] dev-name [dev-num]
                     Test packet transmission over a  specific  network  device.
                     Use  the  RTSVC  program  to  display  the  names (used for
                     'dev-name') and controller numbers (used for 'dev-num')  of
                     the network devices attached to your node.

                     If  you  do  not also specify a -N option, RTCHK broadcasts
                     its test packets. If the network  contains  more  than  one
                     other  node,  RTCHK  receives  more  responses  to its test
                     packets than expected and prints warning messages.  If  you
                     do  specify  a  -N option with the -DEV option, RTCHK sends
                     the test packets only to the node you specify.

  -S n               Specify the number of test packets  to  exchange  with  the
                     other  router.    If  -S  is  not specified, 10 packets are
                     exchanged.

  -DAT         (D)   Specify that each test packet carries 1024  bytes  of  test
                     data.

  -NODAT             Omit test data from the test packets.


EXAMPLES

  $ rtchk -n 3CE02A8.4851 -s 1000          Exchange 1000 test packets with
                                            node 4851 on network 3CE02A8.
                                            The router must be attached to
                                            that network.

  $ rtchk -nodat                           Exchange 10 short test packets
                                            with the other node attached to
                                            the IIC or T1 connection.

  $ rtchk -dev iic -s 100                  Exchange 100 test packets with
                                            the other node on the IIC or
                                            T1 network.

  $ rtchk -dev ring -n 666                 Exchange 10 test packets with
                                            node 666 on the ring network.
