Remote root login on SL Micro

For enhanced security, new installations of SL Micro 6.1 and later do not allow password-based remote root login anymore, which also affects server and proxy container hosts running on SL Micro and managed SL Micro clients. Also SLE Micro 5.5 clients with password-based remote root login which will when be migrated to 6.1/6.2 will suddenly lose this access and must be newly configured. For more information, see SL Micro Release Notes 6.1 (https://www.suse.com/releasenotes/x86_64/SL-Micro/6.1/index.html#jsc-SMO-405).

While deploying components of Uyuni such as a Uyuni Proxy, by default, password-based remote root login is required. You can enable password-based remote root login with the following steps.

Procedure: Enable SSH root login with a password on SL Micro

  1. On the container host, start a transactional shell:

    transactional-update shell

    1. In /usr/etc/ssh/sshd_config file, set:

      PermitRootLogin yes

    2. Leave the shell with exit to save the new configuration.

  2. Reboot the container host to activate the new configuartion:

    transactional-update reboot
