Rick,

OK, I was able to locate the Etherboss product information online, and note what
I had suspected. There are two types of monitoring.
# Active. The computer being monitored has to have an agent program running on
it. The agent program intercepts the IM conversation, and rebroadcasts it onto
the LAN. This is not the problem here; as noted by Etherboss,

No additional program installation is needed on the monitoring target computers.

# Passive. All computers on the LAN participate in one large open conversation.
This is reminiscent of classical, hub-based Ethernet. You most likely have a
switch, which conducts any conversation between any 2 hosts on the LAN as a
separate conversation, accessible only to those hosts. As noted by Etherboss,

You may need to enable your switch's monitoring feature, which is supported by
most current switch, in order to capture conversations from other computers.

In my experience, when this type of network monitoring is done in a large
(corporate) LAN, TWO things have to be done.
# The switch has to be set to "promiscuous" mode, to enable broadcast of all
traffic to all nodes.
# The LAN card on the monitoring computer has to be set to "promiscuous" mode,
to enable that computer to receive conversations not intended for it.

If you have a problem with executing #1, no problem. In spite of the Etherboss
claim "supported by most current switch", which may or may not be true, simply
buy a HUB, and connect both the router / switch, and both computers, to the hub.

I'm not too sure what you do about executing #2. Not all Ethernet cards support
promiscuous mode. Did you do this on yours? Without being in promiscuous mode,
your card will likely see packets between your sons computer and the switch as
another conversation, and ignore them. Unless Etherboss actually hooks the
Ethernet drivers, and forces promiscuous mode automatically.

This may be a case for Etherboss Customer Support.
