You can configure it to be used on any network. Setting up a Nagios server on any Linux distribution is a very quick process however to make it a secure setup it takes some work. This article will not show you how to install Nagios since there are tons of them out there but it will show you in detail ways to improve your Nagios security. http://www.linuxsecurity.com/content/view/144088 --- Never Installed a Firewall on Ubuntu? Try Firestarter ----------------------------------------------------- When I typed on Google "Do I really need a firewall?" 695,000 results came across. And I'm pretty sure they must be saying "Hell yeah!". In my opinion, no one would ever recommend anyone to sit naked on the internet keeping in mind the insecurity internet carries these days, unless you really know what you are doing. Read on for more information on Firestarter. http://www.linuxsecurity.com/content/view/142641 --> Take advantage of the LinuxSecurity.com Quick Reference Card! <-- --> http://www.linuxsecurity.com/docs/QuickRefCard.pdf <-- ------------------------------------------------------------------------ * EnGarde Secure Community 3.0.21 Now Available (Oct 7) ----------------------------------------------------- Guardian Digital is happy to announce the release of EnGarde Secure Community 3.0.21 (Version 3.0, Release 21).
