    Debian 9 - Networking issues

    Dear all, I would need some advice on the following:

    1. SELKS 4.0 desktop.
    2. Installed on physical server.
    3. /etc/network/interface (File settings)
    > auto lo
    iface lo inet loopback

    iface eno1 inet static
    address 10.0.106.61
    netmask 255.255.255.0
    network 10.0.106.0
    broadcast 10.0.106.255
    gateway 10.0.106.1
    4. sudo vim /etc/resolv.conf (Settings with nameservers)

    When I run ifup eno1, RTNETLINK answers: File exists, ifup: failed to bring up eno1.
    "Network not configured" error displayed.
    Run "ifconfig" only displaying one network which is "lo"

    Run "cd /etc/network >> ls"
    - eno1
    - eno2
    - eno3
    - eno4
    - lo

    Run "cd /etc/network >> ls"
    - if-down.d
    - if-post-down.d
    - if-pre-up.d
    - if-up.d
    - interfaces
    - interfaces.d

    Restarted network settings: service networking restart

    ..... After performing all the above, including a system reboot, there is still no network on the machine. Kindly advise.

    Did you manually retype or use cat to display data?
    As this has an extra space.

    SSH from other server: timeout, cannot connect - port 22
    Route -n: no result
    ifup eno1: RTNETLINK answer: File exist, failed to bring up eno1.

    Re: Debian 9 - Networking issues

    Have anyone faced Debian network issue like this? Understand that its a based OS and Ubuntu is based on this Debian, in certain ways it is smarted compared to Debian, and certain processes are automated. I have also came across this link, https://packages.debian.org/stretch/network-manager, is it something I missed out to install this network manager manually?
