We have a TFTP server running on our network and sometimes we need to get a handle on the requests on the server.  By default if you are using linux and the tftp server through xinetd you won’t have a log file to look at.  Thus you need to use TCPDUMP… here is how you [...]

We have a server in my office we reference a lot.  After X time period it would fall asleep and someone would have to hit the keyboard to see the latest information.  After digging for a bit (and never really finding the answer) I figured it out and decided to document it because I will [...]

To mount an NFS share using fstab (/etc/fstab) you need to know a few things, the hostname or IP address of the NFS server, the share name and where you intend to mount the share at.

If you happen to have a Asterisk solution for voice on your network occasionally it is nice to be able to send faxes from your network without the need of a PSTN line at your endpoint. At my company we do this by running a fax server on an OpenVZ VPS on the same subnet [...]

PLEASE NOTE: I have posted an update for CentOS5.4 and GhostScript 8.70! Today I needed a newer version of ghostscript on my server pool for some back-end processing we do. Updating ghostscript for RHEL5 / CentOS 5.2 turned out to be a pain! I was nearly stucked into RPM hell! **** Warning: An error occurred [...]

I updated the Browser.php class today to detect Google’s Chrome Browser. Additionally, thanks to an idea from Daniel ‘mavrick’ Lang, I added isBrowser($browserName) as a function to version 1.1. Visit the Browser.php class page today to grab the update! Interested in a PHP4 version? Daniel is maintaining a version for PHP4. Example Usage: 1 2 [...]

After digging through the Internet looking for a solution to install PBX in a Flash on an OpenVZ VPS and coming out empty handed I decided to dissect the installation myself and I came up with the following method for installing the PBX system on an OpenVZ VPS. Now, that being said I could not [...]
