How To : Install Nagios Core 4 on Ubuntu Linux

Nagios is one of the most popular Open Source application being used for the purpose of IT Infrastructure and Network Monitoring. Basically, this tool is available in two editions, namely, Nagios Core edition which is Open Source and absolutely free to download and Nagios XI edition that has to be purchased by the user. Of course, Nagios XI will have additional features as compared to Nagios Core, but when configured with additional open source plugins and softwares, Nagios Core can provide you with similar or exact results as those in Nagios XI. But, using open source tools is always preferred by most of the users.

Different Quality Backup Idea

My idea is simple. For media that depends on lossy compression it should be possible to ”patch” the media file with a smaller file of same resolution but a lower quality. The backup file is smaller due to more lossy compression. For this to work on image files the format probably need to loose some dependency on the previous block. One error should not affect the rest of the image. On the blocks you then perform some checks. The idea is then that if you encounter a error in the original big image file then you can patch it with the block of pixels in the smaller backup file. The block in the backup file would be of lower quality but look similar. You probable would not notice that the image has been fixed.

 

For a .jpg photo of 3.3MB I saw that I would only need a 350k version. To keep it simple one could store both versions in the same file as an option. For those who don't make backups I think this would make it easier to recover otherwise lost photos.

 

I hope you found this idea interesting.

 

Low Resolution Preview Idea for Open Source Video Editing

 

An idea to speed up the process and use less resources when editing HD video would be to use a low resolution version of the video as a guide. Akin to 3D software, this would be like rendering the animation first at a low resolution.

So with this you first create a low resolution version of the video. Do all the cuts and effects. Then you preview the result. If the result is good you render the video with the high resolution. With the actions as a script.

How To : Secure Shell (SSH) Password-less Login using SSH-Keygen

    Secure Shell, as the name tells, is the open source and most secure and hence, most used protocol that is used to execute command remotely on a Linux host or to transfer files from one Linux host to another within a network using Secure Copy (SCP). Find more details about Secure Shell in our article- Secure Shell in Linux.

Schedule Your Jobs in Linux With CRON

Most of the Linux users are aware of how commands are run, processes are manipulated and scripts are executed in terminal. But, if you are a Linux system administrator, you might want them to start and execute automatically in the background. As an example, you might consider running a backup job every day, at a specific time, automatically. Or you might consider an example of collecting inventory data of the systems deployed across your network, by running a script automatically on monthly basis. But, how to schedule these jobs and execute them automatically in Linux?

    There is an utility in Linux known as CRON with which you can start your jobs automatically at a desired time and schedule them to get executed periodically.

    Cron utility consists of two parts: The cron daemon and the cron configuration files. Cron daemon is just like any service that is started automatically whenever your system boots. Cron configuration files hold the information of what to do and when to do. The main job of cron daemon is to inspect the configuration regularly (every minute to be more precise) and check if there is any job to be completed.

    In the /etc directory, you will find some sub-directories namely cron.hourly, cron.daily, cron.weekly and cron.monthly. You can put your scripts in these directories, and as their names suggest, they will be automatically executed after certain period of time. For example, if you wish to run a job or service regularly after every week, simple put the script in /etc/cron.weekly directory.
