NAME

       dnping - Loopbacks diagnostic packets through a remote node

SYNOPSIS

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

DESCRIPTION

       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 message.

OPTIONS

       -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 prompted.

       -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 forever.

       -v     verbose mode (default off)

EXAMPLES

       Pings 10 packets through remote node "mv3100"

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

           # dnping  -vti 1000000 marsha
