    How To Configure The AIDE (Advanced Intrusion Detection Environment) File Integrity Scanner For Your Website A file integrity scanner is something you need to have.  Imagine a hacker placing a backdoor on your web site, or changing your order form to email him a copy of everyone's credit card while leaving it appear to be functionally normally. By setting up daily reporting, this notifies you within, at most, 24 hours of when any file was changed, added, or removed.  It also helps establish an audit trail in the event your site is compromised. These instructions are designed for an end user, where you don't need to have root access, to implement and assumes your server has the aide binary installed.  Most hosts will have this installed already, or will install it for you upon request.

  • Flexnet License Monitoring With rrdtool

    tux Author: gbiTags: , , , Comments: 0

    Flexnet License Monitoring With rrdtool Some of you may know the commercial Flexnet Licencing Application (©Macrovision). It's a client-server based solution for managing the usage of socalled Flexnet-enabled applications. You can hold licenses of more than one product on one license-server. As you typically have to buy licenses and licenses can be expensive it would be nice to have a monitoring solution, to see the utilization of the precious licenses, wether they are underutilized (so money is wasted) or are always fully utilized (so that you can suspect that sometimes people can not do their work, or only delayed) which is also a waste of resources. As far as I know there are commercial applications for performing such reports, but again you have to spent money. Why not build a simple system yourself, which shows the actual and past usage in an "MRTG style"?

    Server Monitoring With munin And monit On Mandriva 2010.0 In this article I will describe how you can monitor your Mandriva 2010.0 server with munin and monit. munin produces nifty little graphics about nearly every aspect of your server (load average, memory usage, CPU usage, MySQL throughput, eth0 traffic, etc.) without much configuration, whereas monit checks the availability of services like Apache, MySQL, Postfix and takes the appropriate action such as a restart if it finds a service is not behaving as expected. The combination of the two gives you full monitoring: graphics that lets you recognize current or upcoming problems (like "We need a bigger server soon, our load average is increasing rapidly."), and a watchdog that ensures the availability of the monitored services.
