    Have you tried a traceroute?
  3. Re: First time netplan, can't ssh to server from different subnet

    Well, that looks like the NIC is up and running, has an IP address,etc.
    Can you ping it?

    What is the output from

    ip a

    It may be as simple that your network card name is en01 (enzero1), not eno1

    If not using cloud-init, our netplan yaml should ideally be...
  6. Re: First time netplan, can't ssh to server from different subnet

    Netplan yaml files are fussy about indentation etc.

    try
    ip a
    and

    netplan --debug generate.

    Re: Ubuntu Server Network problem

    Sorry, I should have been clearer in stating that it was an example, to be adjusted to match his own network.

    Re: Ubuntu Server Network problem

    Make and model of PC might help.
    It might be that the network card is not supported, or needs firmware (very likely if it is wireless).

    Re: Ubuntu Server Network problem

    Depends on your network.
    for example, assuming yours is a home network with IP addresses in the 192.168.1.xxx range:
    network is 192.168.1.0, your router is 192.168.1.1, your subnet mask is...
  10. [server] Re: Samba on Ubuntu Server 18.04.1 via Webmin: Files can be read but *not* modified

    Samba is not really routable, so that might be your issue.
    I use it on my home network remotely, but I use it via VPN tunnel.
    You really shouldn't make a Samba server visible on the internet, it...
  11. [SOLVED] Re: How to get reply from website when use command ping in terminal

    resolv.conf is no longer used in 18.04. Netplan is used now.

  12. [server] Re: Samba on Ubuntu Server 18.04.1 via Webmin: Files can be read but *not* modified

    Might be obvious, but have you added the users as samba users as well as linux users?

    Posting the samba.conf file (with any sensitive info redacted) would help.
  13. [SOLVED] Re: How to get reply from website when use command ping in terminal

    pinging by hostname is the issue, the DNS serbver is returning ipV6 info, which ping can't use.
    Try changing your DNS server to 8.8.8.8, or use

    ping6 google.com
  14. [SOLVED] Re: How to get reply from website when use command ping in terminal

    That looks like an IPv6 address, which is a bit odd, as ping is ipv4, and ping6 is ipv6.
    Try


    ip-4 route
    and

    ip -6 route

  16. [ubuntu] Re: Security tools show several risks (rkhunter and chkrootkit)

    Duckhook is right.

    Unless you are running an internet exposed server, there is less reason to worry about Linux security than Windows.
    If this is not the first time that you have run rkhunter, a...

    Re: measures against rootkits

    A Bios password won't stop rootkits.

    try this:


    sudo apt install lynis
    sudo lynis audit system

    which will tell you of vulnerabilities, and advise how to improve your security.

    Re: Linux support for motherboards

    It might be worth looking on the manufacturer's website in the drivers section, to see if Linux is mentioned.
    Some manufacturers actively support Linux.
