Are there any lightweight XMPP server that works well on Ubuntu Desktop 11.04; I basically wanted to learn, test and develop some small application that uses XMPP features.
Available from the software center its claim to fame is "easy to set up and configure, and light on resources."
It appears to be actively developed - detail on the linked website. The PPA on launchpad doesnt look like it is being maintained anymore - so perhaps avoid this and use the deb from the linked website for testing the latest version i.e. Natty is v0.7 whilst the current latest is v0.8.
