Description Jan Stodola 2022-05-09 15:03:31 UTC

There needs to be a way to specify that root login via ssh can be allowed when running a kickstart installation.
anaconda part of this feature is tracked in bug 2033849.


+++ This bug was initially created as a clone of Bug #2033849 +++

Description of problem:

When we do a RHEL 9 install, we need to allow root for ssh based logins by
marking the checkbox. This thing is not recorded to the kickstart generated
for the installation and further it blocks the root account if the kickstart
is used as reference kickstart.

The installation works fine with original install and root login works but
when the resultant kickstart is used for other install the root can't loging
with ssh.

This is common practice administrators follow to have a procedure recorded to
kickstart so will create impact on automated installations and post
installation things.


Version-Release number of selected component (if applicable):

RHEL 9 Beta

How reproducible:

Everytime installing RHEL9 from kickstart recorded from a manual install.

Steps to Reproduce:
1. Install RHEL 9
2. In user section allow ssh based login for root
3. Copy the /root/anaconda-ks.cfg file for another install
4. The another install will not allow root login with ssh

Actual results:

Fails to record kickstart properly.

Expected results:

Shall record the option.

Additional info:

We don't see this to RHEL 8 so probably addition of this feature needs some
work in RHEL 9

There is a workaround via %post script for kickstart installations:

%post
echo "PermitRootLogin yes" > /etc/ssh/sshd_config.d/01-permitrootlogin.conf
%end

FYI, the workaround has been also added to the official documentation:

Proposing to 9.1.0 planning.

Comment 1 Brian Lane 2022-05-09 17:03:29 UTC

Are you saying that when you use sshkey https://pykickstart.readthedocs.io/en/latest/kickstart-docs.html#id57 to set a root ssh key (for the *installed* system's root) that they cannot login?

Or are you saying that it isn't included in the example kickstart that's generated?

Or something else :)

A couple example kickstarts would also be helpful.

Comment 2 Brian Lane 2022-05-09 17:12:14 UTC

Oops. I think I understand now, I missed the mention of 'password' somehow. My brain seems to assume all ssh access is via keys :)

So it looks like the problem is:
 * Anaconda has a GUI option to allow root password ssh logins
 * kickstart does not have a way to express that as part of 'rootpw'

So I think the solution here is to add a '--allow-ssh' option to the 'rootpw' command.

As always, this also needs to be added upstream first.

PR - https://github.com/pykickstart/pykickstart/pull/409

Comment 4 Jiri Konecny 2022-05-09 19:45:35 UTC

Thank you for creating the PR so quickly Brian.

Comment 7 Brian Lane 2022-05-31 21:29:43 UTC

rhel9-branch PR - https://github.com/pykickstart/pykickstart/pull/411 (had to replace F37 usage with RHEL9 and also tweaked the tests so they will run on py3.9 or py3.10 for easier local testing).

Comment 12 Brian Lane 2022-06-16 15:29:09 UTC

Adding https://github.com/pykickstart/pykickstart/pull/412

Comment 13 Jan Stodola 2022-06-20 15:43:49 UTC

Moving back to Verified:Tested, the patch from comment 12 is included in pykickstart-3.32.7-1.el9

Comment 17 Jan Stodola 2022-06-27 07:43:03 UTC

Checked that pykickstart-3.32.7-1.el9 is in nightly compose RHEL-9.1.0-20220627.0 and the prepared documentation looks good.

Moving to VERIFIED
