Problems of Using dnf

• dnf (a software to update the system) is needed in some of the lab exercises
• Due to the end of the support of the CentOS 8, the CentOS dev team moved the software repository to another location.
• In order to use dnf, please run the following commands:
  
  

  sed -i -e "s|mirrorlist=|#mirrorlist=|g" /etc/yum.repos.d/CentOS-*
  sed -i -e "s|#baseurl=http://mirror.centos.org|baseurl=http://vault.centos.org|g" /etc/yum.repos.d/CentOS-*

• Please type these 2 commands carefully. These 2 commands use regular expression to replace the old software repositories with the new destination

Overview

• The morning lecture will cover topics related to Linux networking administration
• These topics will directly tie into the lab exercises, making attendance crucial to save time on completing them independently
• Attendance will not be recorded during the morning lecture
