If you are planning to have multiple Euphony installations active at the same time on your local network, you should know that with default installation you will have hostname conflict since all Euphony machines will have the same default hostname: 'euphony'.

You need to change the default hostname: 'euphony' to some other name so each Euphony installation has a unique hostname.
Note that valid characters for hostnames are ASCII(7) letters from a to z, the digits from 0 to 9, and the hyphen (-).
