Network configuration in Ubuntu 18.04 LTS using netplan
With Ubuntu 18.04 onwards, configuring IP addresses stands different from the older versions.

Netplan has been presented by Ubuntu engineers in Ubuntu 17.10 where we no longer use the “interfaces” file to configure IP address but does the task using a YAML file with all default arrangement documents found under /etc/netplan/ directory. In this blog, we will check on how to design static …

A serious vulnerability named Dirty COW has been discovered recently which has put the Linux kernel under risk. It is said that this vulnerability was noticed nine years ago (since version 2.6.22 in 2007) and remained unnoticed throughout this time. A researcher named Phil Oester was the man behind the detection of this serious threat. According to him, the vulnerability is described as a race condition where the Linux kernel’s memory subsystem handles the copy-on-write (COW) breakage of private read-only memory mappings. In this way, the attackers gain write access to …
