Authentication Monitor for Debian and Ubuntu

What is Authentication Monitor?

If you have a Linux server running Debian or Ubuntu and want to be notified when certain users gain access to one or more of your critical services (e.g. “ssh/sshd” and “proftpd”), then Authentication Monitor might be just what you’re looking for.

Authentication Monitor runs silently in the background as a system service and monitors a user-defined list of services running on you server. Whenever a user successfully authenticates with one of these services from an unknown IP-address, you will receive an e-mail notifying you of the incident.

We sometimes buy new hardware and when faced with discontinued models, we of course have to find new ones. Last time we decided on the HP t5550 Thin Client, which were to prove a bit of a challenge when we had to upgrade our Debian installation with a newer kernel.

How I Got “lm-sensors” Working on my Via Epia SN1800 Motherboard

via.8azvymjas0kc0s4k4s8wg8kk4.17ldmg3f9ou8088wk04c40sgo.thI’ve been the owner of a Via Epia SN1800 motherboard for quite some time now, and ever since I got it, I’ve always wanted to be able to monitor the CPU temperature from inside the operating system.
