Summary Steps

1. Establish a terminal connection
2. Set static IP address
3. Reserve static IP address

Detailed Guide

1. Establish a terminal connection

• Install and configure SSH & Web Terminal Addon
• Enter a temporary username and password in the Addon configuration

ssh:
  username: hasmaster
  password: HAS2019
  authorized_keys: []
  sftp: false
  compatibility_mode: false
  allow_agent_forwarding: false
  allow_remote_port_forwarding: false
  allow_tcp_forwarding: false
zsh: true
share_sessions: false
packages: []
init_commands: []

• Start the service

• Take note of the automatically generated keys in the log
• Copy and update configuration to include the rsa key fingerprint
• Remove temporary password

  username: hasmaster
  password: ''
  authorized_keys:
    - 'SHA256:YtNRRsnO...root@a0d7b954-ssh'
  sftp: false
  compatibility_mode: false
  allow_agent_forwarding: false
  allow_remote_port_forwarding: false
  allow_tcp_forwarding: false
zsh: true
share_sessions: false
packages: []
init_commands: []

• Start the Addon
• Refresh the log to see properly running

Note: if the default port 22 is in use, the addon will not start. change the port to something else

Alternatively, Access Terminal on VM

Connect to terminal window
Login as "root", no password
Type Login
Then proceed with commands below

2. Set Static IP Address

• Use nmcli to identify your connection

nmcli connection show

# nmcli connection show
# nmcli con show
# nmcli c s

nmcli connection edit "network-name"
nmcli> set ipv4.addresses 192.168.2.100/24
Do you also want to set 'ipv4.method' to 'manual'? [yes]:
nmcli> set ipv4.dns 1.1.1.1
nmcli> set ipv4.gateway 192.168.2.1

nmcli> print ipv4

nmcli> remove ipv4.addresses 192.168.1.100/24 (to remove addresses)

nmcli> save
nmcli> quit

3. Reserve static IP address

• Configure router so it doesn’t offer your static IP address via DHCP to other clients
