Is your OS set up to have a long hostname? What does hostname --long show? I think Erlang expects to see something like <a href="http://mybox.domain.name">mybox.domain.name</a>. Very often, home or personal Linux installations are created without a domain name, so hostname --long returns something just like "mybox". You need to change this so that you have a domain name. To do this, I think you would need to set your box to have a static IP address (not DHCP) and modify /etc/hosts so that the static IP address for your box is known by a fully qualified name, e.g.<br>
<br>/etc/hosts:<br><a href="http://127.0.0.1">127.0.0.1</a> localhost<br><a href="http://192.168.1.100">192.168.1.100</a> <a href="http://mybox.mydomain.com">mybox.mydomain.com</a><br><br>If you're not actually on a real domain (which is probable), you'll need to make one up.<br>
<br>Hope this helps. It worked for me.<br><br><div class="gmail_quote">On Wed, Jun 18, 2008 at 9:48 PM, John Chandler <<a href="mailto:morph@growler.net">morph@growler.net</a>> wrote:<br><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
I was following an example and found that my configuration lacks the<br>
ability to "set long node name."  I checked the crash dump, and it<br>
wasn't informative to me.  I would attach it, but it's 180K, so I'll<br>
only do that if asked to.<br>
<br>
So, any idea what I should change in my configuration?<br>
