MAKING THE VIRTUAL MACHINE ITSELF PUBLICLY AVAILABLE IS NOT OFFICIALLY RECOMMENDED.
This is rather atypical as we would have expected that all of you would either use a dedicated setup using only the scripts or the extremely convenient “Thin” server methodology.
What follows is only relevant if you are making our virtual machine image publicly reachable (usually through the “Bridged Adapter” setting in VirtualBox).
If you are using a “Thin” server, the steps are still recommended, but not strictly necessary if you trust the “Thin” server operator.
If you use a dedicated setup with only the scripts, the steps are not required.
If you have initialized your virtual machine before April 22, 2020, 10:34 am GMT+2, please open the “Terminal Emulator” and execute the following to set a new password for the “lab” user:
Please set a strong and secure password.
This prevents unwanted logins into the virtual machine using SSH. Please remember that you will have to use the new password everywhere you previously used the builtin standard password “lab”. So you will have to use the new password on the login screen, when using FileZilla, and so on.
Changing the root password is not required because our stock VM image already prohibits root logins.
If you do not wish to use FileZilla or SSH, please consider disabling sshd altogether:
sudo systemctl stop sshd
sudo systemctl disable sshd
On April 22, 2020, 10:34 am GMT+2, I introduced a change that forces users to change the password during the initialization: https://gitlab.com/cler1/ztree-unleashed/-/commit/d3ad254fcb55d93d87373752e66832d5ae718540
If you are the single person using the VM, please consider setting the password to something random and only use public key cryptography: https://debian-administration.org/article/530/SSH_with_authentication_key_instead_of_password
In any case, we recommend using
to always use the latest version of z-Tree unleashed.
