    After adding ens7 to

    network
    version:  2
    rendereder: networkd
    ethernets:
    ens3:
    dhcp4: yes
    dhcp6: yes 
    ens7:
    dhcp4: no
    dhcp6: no
    addresses:
    - 10.0.0.2/8
    gateway4: 10.0.0.1
    

    and checking with:

    $ sudo netplan apply --debug
    

    all seemed well, but I can no longer ssh into my box now. Why?

      Can you try this >>

      # telnet yournewipaddress 22
      

      that should tell you if open or available, also change the yes and no to true and false.

    How is it, that in 2018 the configuration of your networks is decades behind Redhat 6?? Since when have we been reduced to config file editing, when the old classic blue and red config menu’s were fantastic. I dunno, even Raspberry Pi has better tools out of the box…..

    Hi,

    Looking to set up a static IP address in preparation for setting up a personal VPN via raspberry Pi

    Cannot find not generate a netplan file at all

    Configuration of ethernet looks as follows:

    Just a “Rank-Pensioner” amateur who can copy & past but does not understand much about Linux!

      If there is no default netplan config file, try to generate one as shown in the article, then put your config in there. For more information, read the netplan man page.

  4. Pabs says:

    dhcp4: yes
    dhcp6: yes

    dhcp4: no
    dhcp6: no

    has to be changed to
    dhcp4: true
    dhcp6: true

    dhcp4: false
    dhcp6: false

    • Aaron Kili says:

      @Pabs

      Yes, this is correct but yes or no values also work. After i installed Ubuntu 18.04, one of the default interfaces using dhcp4 had a value of yes(see the screenshot in article).
