NAME¶dnping - Loopbacks diagnostic packets through a remote node
SYNOPSIS¶dnping nodename [user pass] count
dnping nodename [options] nodename
[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.
- -c number
- Number of packets to send (default 10)
- 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.
- Quiet mode (default off)
- -s size
- size of frame to send in bytes (40 data + 68 hdr)
- 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.
- 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
