# dnping(1)

Loopbacks diagnostic packets through a remote node

## 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\
