NETPATH is a program to trace a path between any two arbitrary DECnet nodes.

It requires NETMBX privilege, and access (via proxy login or default DECnet
account) to the NML object on each node along the path.  By default, NETPATH
traces the path from your current node to the node you specify.  However,
by specifing two nodes at the prompt NETPATH will trace the path from the
SECOND node to the FIRST node (backwards from what might be considered
natural;  however, the second node is labelled as the "starting point").

Please note that not every router supports NML (in particular, neither
cisco nor Proteon support NML), so NETPATH cannot always trace a path from
one place to another.  The estimated round-trip time (RTT) for packets in
milliseconds is also displayed for each node along the path.

Nodes can be specified by name or by address in either 16 bit decimal
number format or in area.node format.

E.G.,

$ r netpath
