[time-nuts] Time Server

[Simon Ritchie]

Apologies in advance if you already know some or all of this ...

The instructions that you mention show you how to build an Arduino with a
wired network connection.  It has IP address 192.168.1.251.  The Arduino
offers a time service to other machines on your network.

You then need to connect the arduino to your broadband modem using an
Ethernet cable.  Other machines on your network can then connect to the
time service using that IP address.

The instructions also explain how to configure your PC to connect over the
network:

"Download the Dimension 4 software to the client PC. To set the IP address
of the Time Server, select ‘settings’ then type 192.168.1.251in the Server
window and ‘Arduino’ in the Location window. Select OK. Under ‘Advanced’
check that ‘Use the selected server’ is selected. Under ‘How often’ on the
front page set the update rate as required (e.g. every 15 minutes)."

You are getting an error message about localhost.  That's just a name for
"this machine" on a network.  Is the error message coming from the Arduino
or from the PC that you are trying to connect?  Either way, you shouldn't
be trying to get a time service for this machine from this machine.  You
should be setting up the PC to get the time from the Arduino.

Hoping this helps.

Regards

Simon
