asadmin create-domain fails: all ports are in use

Question

I'm trying to create a new domain with the asadmin tool, but it fails every time reporting that all ports are in use. The OS is Fedora 19. What could be the problem?

$ ./bin/asadmin create-domain testdomain
Enter admin user name [Enter to accept default "admin" / no password]> 
Default port 4848 for Admin is in use. Using 52447

I had the same issue and it finally turned out that my hostname was not configured inside of the /etc/hosts file. The error given by asadmin is somehow misleading. :-(

You could check if your hostname was correctly configured by:

ping `hostname`

If you get a "ping: unknown host" error you have to fix your hostname.

Login as root and fix your hostname using:

hostname "<YOUR_HOSTNAME>"

and to make it permanent by

echo "<YOUR_HOSTNAME>" > /etc/hostname

You also have to check that your /etc/hosts file contains a line like:

127.0.0.1        <YOUR_HOSTNAME>

after doing this you should not get the unknown host error when using ping.

I got the idea for the solutions from replies to this question.
