Unable to open socket connection to xcatd daemon on localhost:3001.

When I did a tabedit site to check my configuration, I encountered this error

Unable to open socket connection to xcatd daemon on localhost:3001.
Verify that the xcatd daemon is running and that your SSL setup is correct.

The solution to this error is quite easy. You just need to check your /etc/hosts. Have you # out your. In other words, make sure you have a line like this in your /etc/hosts

127.0.0.1       localhost.localdomain                   localhost

That's it.....
