Ejabberd: Configuration
Guys, we don't exactly know why it seems to be so hard for you to drop the default ejabberd.cfg packaged by Debian. But it seems it badly hurts your feelings. We are sorry, but the default Debian ejabberd.cfg is a configuration for basic chat server (which is very great for a chat server). Archipel needs more advanced options to be a full XMPP server. So please, rm /etc/ejabberd/ejabberd.cfg, copy the following sample in a new file named /etc/ejabberd/ejabberd.cfg, and replace the occurrence of FQDN by your actual FQDN (and also eventually update the path of the TLS certificate). Please, stop trying to adapt the default config file because most of the time, you miss several tokens and it makes Archipel sad. If you really can't remove the original file for sentimental reasons, rename it to ejabberd.cfg.orig. Then, later, you will be able to print it, frame it, and cherish it until the rest of your life :)
Important note: If you can't start ejabberd with this config file, this is mainly because something is wrong with your module installation, and Archipel will certainly not work.
This sample file contains the ejabberd configuration needed for Archipel. It is not ready for production, but allows you to quickly start playing with Archipel.
WARNING: some file paths may need to be tweaked to match your ejabberd install.

sed -i 's/FQDN/your.fqnd.com/' /etc/ejabberd/ejabberd.cfg
If you have not access to a DNS, you need to add in all the /etc/hosts files of your platform:
X.X.X.X your.fqdn.com
Generate your self-signed certificate if you don't have any.
Important note: Be sure to enter your FQDN when asked for "Common Name (e.g. server FQDN or YOUR name)".
openssl req -new -x509 -newkey rsa:1024 -days 3650 -keyout /etc/ejabberd/privkey.pem -out /etc/ejabberd/ejabberd.pem
openssl rsa -in /etc/ejabberd/privkey.pem -out /etc/ejabberd/privkey.pem
cat /etc/ejabberd/privkey.pem >> /etc/ejabberd/ejabberd.pem
rm /etc/ejabberd/privkey.pem
You then can start Ejabberd with the following command:
ejabberdctl startWait 10 seconds and check if it is started:
ejabberdctl status
> The node ejabberd@FQDN is started with status: started
> ejabberd 2.1.8 is running in that nodeIf you are getting Failed RPC connection to the node ejabberd@localhost: nodedown, modify your /etc/ejabberd/ejabberdctl.conf:
ERLANG_NODE=ejabberd@FQDN
You need to register a XMPP admin account (if you want archipel to work out of the box, just name it admin):
# ejabberdctl register admin your.fqdn.com yourpassword
Do not create any other account for virtual machine or hypervisor. You can create as much as user accounts as you want.
