Often times I still come across .daa files. Although we can burn these to disc as a image I prefer the .iso format. Anytime I get a .daa file I normally convert it to .iso for storage. .iso files seem easier to work with and more burning programs supChange into the newly port its format. I decided to make a quick post on converting these in Linux. As with every thing in Linux I am sure there are lots more ways to do this however my way is all via command line so it can be easily done via ssh on servers which, for me is very useful.
I wrote a previous article about obtaining the BIOS version on a Dell Poweredge 650 server which had the end goal of updating the BIOS version on the server if a new BIOS version was available. So after obtaining the BIOS version of the Poweredge 650 server I needed the Dell Service Tag from the server so I could use Dell’s web site to see if a new BIOS version was available. Below is information on how to obtain the Dell Service Tag as well as the Dell Express Service code for the server if it is running a Linux operating system.
If you are a system administrator you probably manage one or more email servers so things eventually will go wrong and need to be resolved as quickly as possible. It is beneficial to know how to troubleshoot email servers using telnet via a shell so you don’t have to rely on a GUI mail client. Below I describe how to login to an Exim email server using telnet, authenticate via SMTP authentication, and then send test emails. The below examples will be run from a terminal window on Linux however they should be very similar too running the commands from a Command Prompt on Windows 7 or any other operating systems using a terminal window or similar.
We previously published an article on how to convert .WRF and .ARF files generated from WebEx presentations to .WMV format to be viewed without requiring the WebEx Player. Since many people have iPhone’s, iPod Touch’s, and use Mac’s running OSX it makes sense to follow up on that article and show how to take the .WMV files to .MP4 format so it can be synced to your iPhone or iPod Touch or simply played in QuickTime on your Macintosh computer. Follow the directions below to convert the WMV file, which was generated from a WRF/ARF file in this article, to MP4 format.
Someone sent me a WebEx webcast they wanted me to view this afternoon. The file had a .WRF file ending which stands for WebEx Recording Format which is one of the two file formats that WebEx webcasts are saved as. The other format that WebEx files are saved as is the ARF or WebEx Advanced Recording Format. Typically you could simply download the WebEx Player available by clicking here however you may want to convert this video, which requires the WebEx Recording Editor, to provide to others in a format they can view without having to install an application. It took me awhile to figure out how to convert this file properly since I only seemed to be able to find the older WebEx Editor versions. I finally signed up for a trial account and was able to download version 3 of the WebEx Recording Editor which allowed me to convert to WMV format and from that I was able to convert to any other video format including AVI, MP4, XVID, and MPEG. Follow the directions below to first convert the .WRF to .WMV and then the second set of directions if you want to convert to another video format.
