Welcome to the Planet IT!

Another plugin that was released to the public. This plugin checks the status of HP Smart Array Controller Series by using "hpacucli.exe", the produced output is compatible with Nagios.

I'm starting a series of my Nagios plug-ins, first plug-in "Check Files - Windows NRPE plug-in". This plug-in counts the number of files in given directory and its sub-directories, with optional filters applied. The output is compatible with Nagios.

So, I decided to switch to Nagios 3 (at last)! In order to make sure that the switch will worth it I was waiting for Centreon to support Nagios 3. In this guide I will go through all steps required to build a fully ready Nagios 3 with Centreon environment.

I've recently migrated one of my servers to Debian 5.0 (Lenny) which by default using RSyslog as its logging daemon, but PHP-Syslog-NG designed to work with Syslog-ng daemon. I didn't want to replace the default RSyslog, so after some Googling, I found a way to make PHP-Syslog-NG to work with RSyslog. This step by step guide explains how I did it.

This is my second article about publishing the Outlook Web Access using reverse proxy. This time I'll cover the configuration of Reverse Proxy using Nginx. Nginx (pronounced as "engine X") is a lightweight, high performance web server/reverse proxy and e-mail (IMAP/POP3) proxy. The reason that pushed me to use Nginx and not Apache is that I started to have some issues with Apache after I moved to Exchange 2007. Everything worked fine except of ActiveSync, which caused connection errors for not Windows Mobile phones like Nokia E61/E71. The other reason is the Nginx is very little resource consumer, and I wanted to improve performance of my Reverse Proxy.

Installing Antivirus Software on Microsoft Servers needs some attention. Therefore, it has always been a long argument to install and configure different antivirus software on different Microsoft Server Platforms. Some IT consultants do not even recommend installing antivirus software on Critical Servers. Of course vendor documentation is very important and must be analyzed before installing any antivirus products to servers. But Microsoft has its own recommendations and Best Practices to take into consideration.

Certificate Signing Requests (CSR) are sent to a Certificate Authority (CA) to be signed. Once signed, a certificate will be returned. At no point should the private RSA key be sent anywhere. Be sure to check with the CA in question for any instructions not covered here.

When you install a latest update rollups for Exchange 2007 with or without SP1, you may discover that Exchange services are not starting anymore. Even though Microsoft provides a workaround for this problem, I solved this issue differently...

This little trick will help you to improve performance on Servers that run in virtualized environment. Specifically that run on free VMWare Server.

If you are running on the cutting edge, with Ubuntu Hardy 8.04, and recently decided to install VMware Server Console on that machine you may have gotten a very strange error message...
