    I want to change the dns in resolv.conf

    This is almost impossible in putty – I want to use the editor in WinSCP

    BUT

    How do I get root access ????

    Then wscp as root

    Ooops!

    Doesn’t work.

    sudo passwd root allows successful change

    BUT

    access is denied on login

    ?????

    Something else going on
    Did it many times with no problems
    Did you try ssh in as root?
    Did you change anything else?

    No changes. Login as pi, sudo passwd root … changed successfully. Login as root … access denied

    Tried su with root password – changed password again – successful change. Login as root … access denied

    Must need a root login routine enabled.

    Hmmm ….

    To enable SSH login for a root user on Debian Linux system you need to first configure SSH server. Open /etc/ssh/sshd_config and change the following line:
    FROM:
    PermitRootLogin without-password
    TO:
    PermitRootLogin yes

    Had a look at the file and it doesn’t contain any PermitRootLogin line ???

    Adding the line works.

    What a performance!

    Of Course but never had to
    By default is enabled on most of Linux flavours
    I usually had to do the other way around
    Disable root ssh in

    Apart from the above task …. changing the dns in Jessie requires the following:

    Using DNS Servers in Debian/Jessie

    and

    add the line

    name_servers=n.n.n.n (the actual dns nameserver address)

    to /etc/resolvconf.conf

    It should be a lot easier than this!
