For a more secure terminal (SSH) environment, you can add a second factor to authenticate a user. I personally run Ubuntu and i implemented the Google Authenticator on my Ubuntu system using the Google Authenticator Library of Google in combination with my iPhone with the Google Authenticator App.

Zabbix 1.8.6 has been released on August 4th. Within this relase several new features have been added and even more improvements are implemented:
On-demand reload of configuration cache
Added ability to force configuration cache reload of a running server and proxy, which, in the case of active proxy, will also force config re-read from the server.

Zabbix will complain if there are unsupported attributes in server, proxy or agent configuration files.
Compatibility with PostgreSQL 9.x
It is safe to use Zabbix with the latest releases of PostgreSQL.
Monitoring of LVM devices

Hosting in the cloud(s)
As of today my websites are hosted fromout a cloud environment at OVH. I was interested in what way cloud computing could offer me cost savings and flexibility. I will test the current environment for a few weeks to see if it can offer the same performance- and uptime characteristics as my local VMWare ESXi 3.5 environment.
As a pay for every hour i will play around with amount of internal memory. Please notify me if my site gets too slow 🙂
