       dnping - Loopbacks diagnostic packets through a remote node


       dnping nodename [user pass] count
       dnping nodename [options] nodename
       [qsv]  [-c  number] [-i interval] [-p password] [-s size] [-u username]
       [-w timeout]


       This utility sends to remote DECnet node nodename the number of packets
       specified by count to test the link between the two systems. Optionally
       a username and password may be specified for the connection as well  as
       several  other  options.  NOTE  that if you dnping another Linux box it
       must have dnetd running.
       NOTE also that dnping is not really like an IP "ping" in that it  needs
       a  registered  object  at the other end to connect to. So, just because
       you cannot ping a machine does not, necessarily, mean that  machine  is
       not  available,  just that the MIRROR object is not available. There is
       not (to my knowledge) a low-level equivalent in DECnet of the ICMP ping


       -c number
              Number of packets to send (default 10)

       -d     Debug mode (default off)

       -i interval
              interval between packets in microseconds (default 0)

       -p password
              Access  control  password.  If  this  is  "-"  then  you will be

       -q     Quiet mode (default off)

       -s size
              size of frame to send in bytes (40 data + 68 hdr)

       -t     timestamps mode (default off)

       -u username
              access control username

       -w timeout
              Specifies a timeout (in seconds). If not  response  is  received
              after  this  time then dnping will abort. The default is to wait

       -v     verbose mode (default off)


       Pings 10 packets through remote node "mv3100"

           # dnping mv3100 10
       Make it look a bit like IP ping:

           # dnping  -vti 1000000 marsha
