Not clear on what you are doing, so here is the brief description:

- you have two machines - say "midas" and "frontend"
- you run mttpd, mlogger, etc on "midas"
- you want to run some frontend on "frontend"

Do this:
- on "midas", open a new terminal, run "mserver -p 7071"
- on "frontend", open a new terminal, run "odbedit -h midas:7071"

If you did follow all the online instruction correctly, at this point, your odbedit on "frontend" would have 
connected and all commands would work same as if run locally on "midas".

If I understand you correctly, you got this far.

Next do this:
- on "frontend", open a new terminal, run "your_frontend.exe -h midas:7071"

If all is good, the frontend would start, would connect to midas, you would see
it in odbedit "scl" and on the midas status page and you would be able to stop
it from the midas "programs" page. (this last bit is important).

I guess this is where things go wrong and you do not get anything working.

Do this:
a) cut and paste all the output from the terminal window where you are running the mserver (including the 
command you used to start the mserver)
b) cut and paste all the output from the terminal window where you are starting the frontemd (again, 
including the command you used to start the frontend)
c) cut  and paste the contents of midas.log (in the experiment directory) from the time you started the 
mserver until the very end.

Paste all this as reply to this message or email it to me at olchansk@triumf.ca

With this additional information we should be able to get you going (and hopefully improve the 
documentation so the next person does not run into the same problem - whatever the problem turns out to 
be).

K.O.
