Some Handy and Fun configuration of mine!

DISCLAIMER Author will be not responsible for the harm cause done by using this configuration, Make Sure You have the backup before applying these settings

Please don't use this setting blindly, if you are looking default behavious and settings, it might not act like what you want because its specially tailored for my needs.

• timezone

  When the servers and you are few degrees of longitude away!

  #+BEGIN_EXAMPLE root@host # timedatectl set-timezone Asia/Kathmandu #+END_EXAMPLE

• Hostname

  I wonder why people just name their host as their name, choose the proper hostname, can save you from disaster.. like production machine or testing.

  it can be easily changed on live without changing hostname.

  #+BEGIN_EXAMPLE root@host # hostnamectl set-hostname myhostname #+END_EXAMPLE

** get machine info

#+BEGIN_EXAMPLE root@host # dmidecode | grep "System Information" -A20 #+END_EXAMPLE

• Keymap

  yeah I use dvorak! you might not want to copy this!

  #+BEGIN_SRC bash localectl set-keymap --no-convert keymap #+END_SRC

  which changes and creates =/etc/vconsole.conf= file for persistance.

• Swappiness

  The Linux kernel provides a tweakable setting that controls how often the swap file is used, called swappiness

  A swappiness setting of zero means that the disk will be avoided unless absolutely necessary (you run out of memory), while a swappiness setting of 100 means that programs will be swapped to disk almost instantly.

  #+BEGIN_EXAMPLE $ cat /proc/sys/vm/swappiness 60 #+END_EXAMPLE

  for persistance change add

  #+BEGIN_EXAMPLE vm.swappiness = 10 #+END_EXAMPLE

  to =/etc/sysctl.conf= as root and reboot

  You can also change the value while your system is still running

  #+BEGIN_EXAMPLE sysctl vm.swappiness=10 #+END_EXAMPLE
