Mop probe utility

Usage

mopprobe [{-3 | -4}] [-aov] interface

Overview

mopprobe prints the Ethernet address and nodename of DECserver 100/200/250/300 on the Ethernet connected to interface or all known interfaces if -a is given. If -o, inhibits all messages but the first from a node. With -v all MOP/RC SID messages will be shown (e.g., machines running DECnet).

The options are as follows:

-3

Ignore MOP V3 messages (Ethernet II).

-4

Ignore MOP V4 messages (Ethernet 802.3).

-a

Listen on all the Ethernets attached to the system. If -a is omitted, an interface must be specified.

-o

Print a node just once.

-v

Show all nodes sending MOP/RC SID messages.
