OK, that tells me what I needed to know.

When I run the excas program on the netBSD machine, I get a message saying the server isn't attched to a network.  Looks like I haven't got the dependent code quite right.  I'll correct it now that I know what doesn't work.

Thanks for the info.

Hi:

So you built EPICS base on a Linux machine and NetBSD?
Then you can test some things before you get into striptool etc.

EPICS base comes with a 'excas', 'cainfo' and 'camonitor'
commandline program.
Run excas on one machine.

While it's running, type
	camonitor fred

You should see values.

Try the same on the other machine. Same result.

Now try 'excas' on one, 'camonitor fred' on the other.
Doesn't work?
Are they on the same subnet?
If not, try
   EPICS_CA_ADDR_LIST=<ip of the machine that runs excas>  camonitor  
fred

Still doesn't work?
