Linux is a different technology altogether unlike Microsoft and Mac OS. It requires more vigilance to be a good Linux User. Remember, we have already talked about in our earlier articles that Linux is not a product like Windows, but a technology that needs to be treated in a polished manner. If you understand few basics, you can make the most of the open source technology, which can definitely provide you various advantages over Windows or Mac OS. If you are using Ubuntu, you must be aware of package-management system and .deb packages from where you can downloads a range of free software and tools. Apart from this, there are various other applications that are available in source form and you can install them very easily. It is good if your install software from .deb packages and they work more smoothly. After software and applications, updates are the next thing that you should take care off. Don’t neglect them and keep updating the necessary updates installing in order to keep your system advanced.
When it comes to security, Linux is the first choice but if you have set up the root password very weak, you might be in trouble. You should try to keep it very strong. Don’t hesitate even if you have to store or encrypt the password.
Apart from this, you should also not forget to back up configuration files. If you upgrade X11 that ensure successful GUI operations for networked computers, you should back up the files using /etc/X11/xorg.conf. Likewise, you should also back up Samba, Apache and MySQL.
Some other Errors that you should be take care off are mentioned below:
Don’t ignore the Log Files:
Ignoring the Log Files can be very disastrous for you. You should keep a record of these files in order to run your system properly. To ensure reliable solutions, you can use different third party applications that would prepare a detailed report of issues based on the /var/log files. Remember /var/log/messages is the first thing where you should look in case of any fault.
Don’t log in as a Root User
Login as a root administration can cause you two problems; 1st if you commit a mistake, which is fatal it is going to destroy all your arrangements and 2nd it would allow malicious email and attachments to attach the root files directly.
Deep understanding of Command Lines
If you are a Linux user you should never never and never avoid the command lines. However the user interface would definitely take care of most of the command lines and you don’t have to really learn them by hearts.
Keep the latest Kernel installed
Keep updating the Kernel but remember whenever you update a new Kernel, the old one is still there and you are suggested to remove the same by using following command: rpm -qa
grep -i kernel > rpm-e kernel-{VERSION}.
No need to have a server boot to X
There is no need to have a server boot to X, even if you install X to make the administration work easy when a machine is a dedicated server. It would help you to save memory and CPU cycles. You can also stop the boot process and use the command line at runlevel 3, which would enable your server to access your resources.
