Maintaining Multiple Servers With Monitoring Software
As an IT guy here at iEntry, I wear a lot of hats (i.e. programmer, system administrator, "my email stopped working" guy, etc.) and with so much going on in a day, it's easy to miss when one server out of 40 or so goes haywire and stops serving web pages. We employ an open-source monitoring software called Nagios to help us ensure that are always aware of network down times.

Most of us system administrators often get treated as though we only keep the Internet up, and the replacement hardware and software installed.

Responding To The Growing Threat Of DDoS Attacks
Sony PSN, Qriocity, MasterCard, PayPal, Visa--what do these have in common? They have all sustained DDoS attacks in the past 6 months, PSN and Qriocity just this past month.
