I was asked today to set up an IM server for internal use,   originally they were specifying Windows messanger but I was able to suggest we try a proper standards based system instead 🙂

So I need a server,  a few clicks in the Proxmox interface ( a rather nice way of handling OpenVZ virtualisation) and I have a new blank Debian lenny box already to play with.

Added the non-free option to the apt repository (as we will need the Sun JRE) and off we go :)   Apt decided to moan about :

W: There is no public key available for the following key IDs:
9AA38DCD55BE302B
W: GPG error: http://security.debian.org lenny/updates Release:
The following signatures couldn't be verified because the public
key is not available: NO_PUBKEY 9AA38DCD55BE302B

Which was solved by this post here 🙂

A quick :

apt-get install debian-archive-keyring

and off we go again 🙂

Next stop is the Java monster,  mercifully simple to install nowadays:

apt-get install sun-java6-jre

Next we grab the latest openfire deb,   then install:

dpkg -i openfire_3.6.4_all.deb

Which seemed to be too painless…

Fire up the Wizard on port 9090 from a browser and you are done 🙂
