This is part of a guide to setting up an Ubuntu server for a small/medium business. The server will provide DHCP, DNS, LDAP, Kerberos and NFS services such that users can login to any machine on the network and all their files and settings will be the same across the entire network.
This section will help you configure NFS using Kerberos to secure it.

OpenLDAP is a directory service. Think of it as a database for storing all your users, their passwords and groups. In time you can use it to store much more, but initially we’re going to use it as a centralised authorisation system. Clients will check usernames and permissions against those stored in the directory on the server. Though it is also possible to store passwords in LDAP and use it for authorisation, we’ll be using Kerberos for this purpose.

Your server will automatically request the time from the Ubuntu NTP servers on every boot… but hopefully you’re not going to reboot it very often. It is useful for the server time to be correct when debugging and it is ESSENTIAL for the server and all the clients on the network to have the same time (+-5mins by default) for Kerberos to work.

The first thing to get your server to do is act as a DHCP and DNS server. This will allow you to map hostnames to IP addresses (and vice versa!) automatically. This means all network clients will know that neo.danbishop.org and 192.168.0.2 are one and the same. This is ESSENTIAL if you plan to use Kerberos later on.

The console on Ubuntu 10.04 server is painfully slow under VirtualBox. The solution is to disable the frame buffer module like so:
sudo nano /etc/modprobe.d/blacklist-framebuffer.conf
Then append “blacklist vga16fb” to the end of the file, save and reboot. Problem solved 
There’s been significant progress made with WebLex in the last few weeks. Mainly through avoidance of revision… Anyway, there is now a beta version out for both Ubuntu and Windows. These can be found at http://www.weblex.org/
The latest version is written in Python and will hopefully be coming to Apple’s OS X shortly too. French and Spanish support are still extremely limited, but this will be improved over time.

Loading ...Yup, facebook chat, notorious for being the world’s worst chat platform (yes even worse than MSN) now allows you to connect using XMPP (the best chat protocol in the world).
All you have to do is set a facebook username, then you can connect using username@chat.facebook.com and your facebook password… it really is that easy!
You can see more details and instructions for specific chat clients here: http://www.facebook.com/sitetour/chat.php
