Wow. Batshit V8-based server-side JavaScript environment. Can be used to write web servers, but also just about anything else. Also, has a totally hardcode ‘nothing blocks, ever’ philosophy that means that just about everything happens in closure-based callbacks, letting you write a single-threaded web server that can deal with many incoming connections at once.

Building the MacOS caldav server on linux. Works, too.

I like to run my own jabber server, so that I can be contacted as tom@jerakeen.org. Also, I’m a sucker for punishment. I’ve run serveral different Jabber servers over the last year or so, and yesterday I started toying with ejabberd. It was probably the easiest to set up of any of the servers I’ve tried, and I recommend it.
I’m running Debian etch, and installing the daemon was a matter of:
sudo apt-get install ejabberd
Once installed, edit /etc/ejabberd/ejabberd.cfg. A ‘%’ at the beginning of a line is a comment, and lines finish with a ‘.’ character. This config file is read only once, and the settings are put into the ejabbed server database on startup. Unfortunately, that’s probably already happened, so uncomment the override_acls. directive - this makes the server re-read the ACL settings from this file on next startup.
I’ll assume that you own the ‘example.com’ domain and want the JID ‘user@example.com’. Uncomment the line below ‘%% Admin user’. It wants to be something like
%% Admin user
{acl, admin, {user, "user", "example.com"}}.
Change the line below ‘%% Hostname’ to set the hostname of the server:
%% Hostname
{hosts, ["example.com"]}.
You may want to look through the rest of the settings. But don’t bother, they’re all very boring. Now restart the server, to pick up the new settings:
sudo ejabberdctl restart
ejabberdctl can also register your admin / jabber user if you’ve turned off anonymous registration:
sudo ejabberdctl register user example.com <password>
Right, you’re done. Assuming that the DNS A record for example.com resolves to the machine you’ve been playing with (it doesn’t have to, see below), you now have a Jabber server with an admin user. You can visit http://example.com:5280/ to administer your server, but there’s not a huge amount to do there.
If the A record for example.com doesn’t resolve to your server you can still run a server for example.com by pointing DNS SRV records to your server. In fact, you should do this anyway, in the same way that your email will arrive if the A record for your domain points to the mail server, but MX records are still a good idea.
Assuming your Jabber server runs on a machine called jabber.example.com, you’ll want the following scary DNS records:
_xmpp-client._tcp 900 IN SRV 5 0 5222 jabber.example.com.
_xmpp-server._tcp 900 IN SRV 5 0 5269 jabber.example.com.
_jabber._tcp 900 IN SRV 5 0 5269 jabber.example.com.
You can check that they’re been set properly using this excellent tool, but it’ll probably take a while for the DNS updates to propagate. If you have the dig command line tool, you can also try
dig -t srv _xmpp-client._tcp.example.com
to ask your local DNS server for one of the SRV records.
You don’t have to use ejabberd. Viable alternatives are:

Rui’s LDAP server is based off this thing. If I’m eventually to release my own Net::LDAP::Daemon, I’ll need permission..
