Hi, there. I have not recently run mserver through inetd, and we usually do not do
that at TRIUMF. We do this:

a) on the main computer: start mserver: "mserver -p 7070 -D" (note - use non-default
port - can use different ports for different experiments)
b) on remote computer: "odbedit -h main:7070" ("main" is the hostname of your main
computer). Use same "-h" switch for all other programs, including the frontends.

This works well when all computers are on the same network, but if you have some
midas clients running on private networks you may get into trouble when they try to
connect to each other and fail because network routing is funny.


K.O.
