corey, thanks for your input.

Just encountered an issue like this with a customer. Here are some steps to check:

check /etc/dekiwiki and make sure that mindtouch.host.conf exists

Exists.

If it does then move on and check /etc/init.d/dekiwiki and see if you find a line like this:
source /etc/dekiwiki/mindtouch.host.conf

Deki has to be run as a launch daemon in OS X, that's why there's no init.d script for it. (An identical copy of the same launch daemon runs on an ordinary OS X since weeks. No problem there.)

Here's the daemon:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
	<dict>
		<key>Label</key>
		<string>com.mindtouch.deki</string>
		<key>ProgramArguments</key>
		<array>
			<string>/usr/bin/mono</string>
			<string>/MindTouchDeki/bin/mindtouch.host.exe</string>
			<string>apikey</string>
			<string>xxx</string>
			<string>script</string>
			<string>/etc/dekiwiki/mindtouch.deki.startup.xml</string>
			<string>path-prefix</string>
			<string>@api</string>
			<string>http-port</string>
			<string>8081</string>
			<string>ip</string>
			<string>localhost</string>
			<string>notty</string>
			<string>connect-limit</string>
			<string>-5</string>
		</array>
		<key>StandardOutPath</key>
		<string>/var/log/deki-api.log</string>
		<key>RunAtLoad</key>
		<true/>
	</dict>
</plist>

Once that is done type hostname in the console and make sure that whatever comes up has an entry in your /etc/hosts file

example if the hostname is dekiwiki make sure your /etc/hosts includes:

127.0.0.1 dekiwiki

There's an entry and it can be properly resolved.

Let me know if this resolves your issue

Unfortunately that doesn't solve this mono issue.


As said above, the same configuration runs properly on OS X since weeks now. It's just the server version of OS X where mono doesn't seem to work as expected.


Steve's workaround helps, though... But I can't tell if it has any side effects as I left the Server version aside (mono seems to be too flaky for production on OS X Server - see this thread's issue) and am using Deki on an ordinary Leopard now. So running on Server is still interesting for the future, of course, but no issue for me at the very moment.

Steve - any news on the mono front on this issue?

Hi,

I am a fellow OSX user and have come across this problem too.

The solution is quite simple:
Define a valid DNS name on the default network card configuration. I think that is the only thing you did not try on your original post.

On OSX you'd have to:
1. Open preferences pane
2. Click on Sharing
3. Click on the "Edit button" right under "Computer Name"
4. Enter a valid DNS name (which maps to your ip address on your DNS server) in the Local Host Name field.


I had this problem on CentOS 5.3 and spent many hours racking my brain. I even re-installed the OS and Deki from scratch with no success until I came across the same error message when installing Oracle 10g on another Linux machine. The only way to get Oracle to work was to edit the hostname in the network preferences. I tried it on the Deki machine just for kicks and it came to life just like that.

On Centos I used the DNS tab of the Network Configuration GUI utility to enter the proper value in the hostname field

Thanks for sharing the solution to this problem!
