Linux Assessment Rehearsal - adaley0518/Tech_Journal GitHub Wiki

Centos 7 (hopefully) 1 set machine to LAN

Networking

  • use nmtui
  • address: 10.0.5.4/24
  • Gateway: 10.0.5.2
  • DNS servers 10.0.5.6
  • search domain: amber.local
  • {X} automatically connect
  • then okay
  • set host name: blog01
  • in centos 'systemctl restart network'

Create sudo user

  • log in as root: Ch@mpl@1n!19
  • 'useradd amber'
  • 'passwd amber' (make password)
  • 'usermod -aG wheel amber'
  • type exit
  • log back in as amber
  • Testing:
    • ping c1 google.com/ ad012-amber/ fw01-amber

Secure SSH

  • nano /etc/ssh/sshd_config
  • find 'PermitRootLogin yes' --> change to no and remove #
  • restart ssh --> service sshd restart
  • logout and log in again, so host name takes hold
  • try ssh from ad01 to blog01
    • sudo -i
    • ping champlain.edu

Linux Domain Join

Adjust DNS

  • possibly ad01- check DNS forward lookup zones/ reverse lookup zones

Blog installation

Hopefully this all works! ah
