TOSS 5 must not have the rsh-server package installed.

The "rsh-server" service provides unencrypted remote access service, which does not provide for the confidentiality and integrity of user passwords or the remote session and has very weak authentication. If a privileged user were to login using this service, the privileged user password could be compromised. The "rsh-server" package provides several obsolete and insecure network services. Removing it decreases the risk of accidental (or intentional) activation of those services.

Verify the "rsh-server" package is not installed using the following command:

$ sudo dnf list --installed rsh-server

Error: No matching Packages to list

If the "rsh-server" package is installed, this is a finding.

Remove the "rsh-server" package using the following command:

$ sudo dnf remove rsh-server
