It had been awhile since I have installed NRPE or Nagios Remote Plugin Executor running through xinetd so once I thought I had everything configured I attempted to restart xinetd but NRPE was not working properly. Below I describe the error in more detail along with how I resolved the issue. In the below example the server was running CentOS Linux.
I recently upgraded the Project Management Software, which happened to be Redmine, for a company and after the upgrade I received some complaints regarding SVN not functioning properly. I initially thought there is no way that the upgrade caused an issue with SVN since SVN and Redmine are completely separate however you can browse the SVN repositories from within Redmine. Below I describe the error in more detail including an image of the error from TortoiseSVN, what I did to resolve the issue, and another possible resolution if your issue is different than the one mentioned in this article.
I recently moved Nagios monitoring from one server to another and ran into a couple minor issues. I wanted to point out some of the errors and the steps I took to resolve those errors on a CentOS Linux server. The biggest pain about moving Nagios for me was the fact that I use Monarch to manage the Nagios configuration files and reconfiguring Monarch was a pain because of some of the Perl modules required and the fact that CentOS still favors Perl 5.8.8 instead of Perl 5.10 which includes some of the necessary Perl modules. Anyway once I got past the Monarch issues I still had some minor problems with Nagios which are pointed out below. The errors are from the Nagios web interface.
The below steps will allow you to set up a TFTP server on Linux but specifically on a CentOS server. All you need to do is install a couple files with yum, enable the server, and restart xinetd.

- [root@centos-server ~]#yum install tftp-server
