MSN havent updated all of their servers to the new cert version, so this was causing intermittent problems. The fix here is updated (if you dont want to or cannot upgrade to latest version yet) and the below information is correct and working as of 24/11/2010.

Easy cpanel WHM or linux remote backup – SSH pull rsync backups for security and integrity using incremental
So you have a cpanel/WHM web server, you have it set to back up all of its accounts. Thats either costing you a lot of FTP bandwidth to send to a remote server, or you are being less than resiliant by only backing up to a local disk. Perhaps you have remote rsync SSH backup already, but havent really thought of the implications of running a SSH/rsync ‘push’ system. This howto is your solution. This howto is not just relevant for Cpanel/WHM servers and you can adapt it to any kind of Linux backups you make.
I recently had some interest from a prospective employer who were looking for someone with JBoss and Tomcat experience. Having had extensive use of these systems in my previous role, I figured I would write a quick howto to get people up and running with JBoss in a short time period. Jboss AS (application server) is an open source Java Enterprise Edition (Java EE) based application server, similar to Goldfish. As it is Java based, it runs on multiple platforms and architectures. Jboss features clustering, fail over, load balancing, distributed deployment, deployment API, management API and much more so its a very versatile platform for serving up your applications.
Many a time I have re-installed my system from scratch or created a new system, but get sick of continually installing the same packages over and over. Its annoying when 2 or 3 months down the line you want to use a program you used to have (or have on another system) only to find its not yet installed. Sure, an apt-get install only takes a few minutes for a single piece of software, but that’s a few minutes a geek like me could better spend doing something productive.
What is swap?
Even if you encrypt data on your partitions, something that is often overlooked is your swap partition. Swap is where linux ‘swaps’ programs (and their stored data) from physical system memory onto the hard disk when they are not used. When those programs become used again, the system ‘swaps’ them back into memory. This approach can allow you to run more programs than you have RAM for, at the cost of delay – for example when programs are swapped back into RAM from disk.
You may have noticed that the default installation of Ubuntu doesn’t get your full speed on downloads when updating. This is down to the fact every installation of Ubuntu comes with the main Ubuntu APT repository set as default, and those servers can get overcrowded with the amount of people out there running a default installation.
