Subject: Error connecting to back-end computer 
Dear All,

This is my first time running an experiment on separate computers. I followed 
the documentation (https://midas.psi.ch/htmldoc/quickstart.html) to setup the 
files:
/etc/services
/etc/xinetd.d/midas
/etc/ld.so.conf
/etc/exptab

but when I started the frontend program in the front-end computer I got the 
following error (computerB is my back-end): 

[midas.c:8623:rpc_server_connect,ERROR] mserver subprocess could not be started 
(check path)
[mfe.c:2573:mainFE,ERROR] Cannot connect to experiment '' on host 'computerB', 
status 503

In both front-end and back-end computers only a file '.SYSMSG.SHM' was created 
after the attempt. If I start the frontend program somewhere in the back-end 
computer by connecting to 'localhost', seven .SHM files are created in the 
experiment directory together with a .RPC.SHM in the directory where I run the 
frontend program.

Is that I misconfigure something? I cannot find a solution...

Thanks.

Best Regards,
Jimmy
