Hi K.O.,

Thanks for your reply. I have tried your way but I got the same error: 

[midas.c:8623:rpc_server_connect,ERROR] mserver subprocess could not be started 
(check path)

My front-end and back-end computers are on the same network connected by a router. I 
have allowed port 7070 in the firewall and done the port forwarding in the router (for 
connecting from outside the network). From the error message it seems that some 
processes can not be started automatically. Could it be related to some security 
settings such as the SELinux?

Best Regards,
Jimmy
