Re: Help with the arm64 and ppc64el installation-guides needed



Just read the link re: PermitRoot --without-password

My comment - typical "developer" string - because many people are looking for passwordless login for root, and from my UNIX background I would take "--without-password" very literally. I suspect what is intended is "--no-password-auth-permitted", meaning some other form of authentication is accepted, e.g., PKI.

Because of the comment in sshd_config I was thinking it was something in the PAM configuration I needed to look at. And, FYI - if you follow the suggestion in the sshd_config (re PAM) no login for anyone (using passwords at least) is permitted.

Thank you for the link - I shall copy my keys in (later) and report back. And secondly, for the link - for the changes history! Excellent!

Maybe - last time I tried - I mistyped the login - because login from console is working for both - thanks for the reply.

re: root login on sshd - guess I need to read more carefully. I know about the cipher changes starting with OpenSSH 6.7, but had not yet stumbled on anything extra blocking root login.

My apologies for a false statement! Must test again and again (so I will have to reload ubuntu, opensles and fedora to see which ones of those refuse root login at console. If both are blocked (with the newer openssh) may make some maintenance work difficult.

Further - any interest in a different (in what way please) story on installing debian on PowerVM enabled systems?

The ssh part: yes, and that's documented in the release notes:
<https://www.debian.org/releases/jessie/powerpc/release-notes/ch-information.en.html#openssh>.

The console part: I don't think so; this is probably a bug in wheezy.
The last time I had that sort of problem, it was due to an omission from
the file /etc/securetty (list of devices that root may log in through).
But in wheezy that file does include hvc0.

Q.  Which is the greater problem in the world today, ignorance or apathy?
A.  I don't know and I couldn't care less.
