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
