Turn off Memcached UDP listening in Ubuntu 16.04 to prevent Memcrashed

Submitted by quang on Thu, 03/01/2018 - 09:50

This website is running out of the box with Ubuntu 16.04 and Memcached on. Today, I receive an email which tells me that "a lot about amplification attacks happening on the internet". I don't want to have any harmful thing destroy my VPS, so, I check my Memcached configuration and turn off UDP.

Why should Memcached with UDP port be disabled?

Snap, snaps, snappy, snapd, snapcraft don't make me cry

Recently, I am surprised at a concept which sounds "snap". Unintentional, I visited a website and installed a code editor called Atom. It is easier than downloading *.deb file and type some commands...

Snap, snaps, snappy, snapd, snapcraft will make you confused. But, they all are one method/ tool to package a (or a bundle of) software in Linux family OS. In the past, many software packages methods  as RPMs, DEBs, file .run, file .sh, and zip packages,... Novices will be stuck in a jungle and give up trying Linux before they could recognize it is a beautiful world.

Submitted by quang on Tue, 01/30/2018 - 19:17

Sometimes, you want chit-chat with your readers. Drupal 8 has comment feature but I think it is very simple, not good for real world. So, I have just installed a module for commenting, it named Disqus.

Step by step

1. Register an account at disqus.com

2. Login into Admin Dashboard of your Drupal, and go to admin/modules/install

3. Paste https://ftp.drupal.org/files/projects/disqus-8.x-1.0-rc3.tar.gz into Install from a URL text box and click Install button.


Comming back after more than a year off

Hello Everybody,

Rerouting has been returned. The website disappeared, the domain expired. I cannot control anything because of some changes in my life. I left Saigon to return my hometown - Nha Trang City. Many busy things made me AFK (sounds like I am a genuine hacker) from the day. I am a shopkeeper with a very small shop in a Vietnamese traditional market.

Today, I want to say that "Website rerouting.org is returning". 

I will post some articles when I have some spare time. Playing with a computer makes me happy.
