It was based on Red Hat Linuxbut used a much more conservative release cycle. Later versions included technologies from the Red Hat—sponsored Fedora community distribution project.

    Red Hat Enterprise Linux release schedules do not follow that of Fedora around 6 months per release but are more conservative 2 years or more. Fedora serves as upstream for future versions of RHEL. RHEL trees are forked off the Fedora repository, and released after a substantial stabilization and quality assurance effort. By the time RHEL 6 was released, many features from Fedora 13 and 14 had already been backported into it. There was some cross-pollination between the two up until shortly before the first production RHEL 3 release.

    The Fedora project provides the following explanation: [15]. Fedora is a free distribution and community project and upstream for Red Hat Enterprise Linux. Fedora is a general purpose system that gives Red Hat and the rest of its contributor community the chance to innovate rapidly with new technologies. Red Hat Enterprise Linux is a commercial enterprise operating system and has its own set of test phases including alpha and beta releases which are separate and distinct from Fedora development.

    Originally, Red Hat's enterprise product, then known as Red Hat Linuxwas made freely available to anybody who wished to download it, while Red Hat made money from support. Red Hat then moved towards splitting its product line into Red Hat Enterprise Linux which was designed to be stable and with long-term support for enterprise users and Fedora as the community distribution and project sponsored by Red Hat.

Keep reading to learn how to share a directory with samba, and how to apply the appropriate SELinux context to it.

    The project provides both server and client software to allow interoperation with Windows machines, representing the ideal solution in mixed environments. In this tutorial we will see how to install Samba on Red Hat Enterprise Linux 8, how to setup a samba share, how the setup the firewall to allow access to shared resources, and how to apply the appropriate SELinux context.

    The first thing we have to do is to install samba on our machine.

    How to install and configure samba on RHEL 8 / CentOS 8

    The samba-client package is not strictly needed, but the utilities provided by it can be useful. The next step is the firewall configuration. We must open the appropriate ports, so that the samba-shared resources can be accessible from other machines. Luckily for us, there is no need to open ports manually: all we have to do is to add the "samba" service to our zone. A "service" is just an abstraction which let us allow traffic through all the ports needed by a service, by referencing the service name, instead of having to setup and remember each port used by it.

    In case we want to gather information about a "service", we can run:. To permanently add the service to the default zone, we can run:.

This is needed to allow anonymous access without having to provide a password. After this change, we must append a new stanza dedicated to our share at the end of the file. We will name the shared resource "linuxconfig":.

    To make the changes effective, we must restart the daemons:. To protect access to a resource with a login prompt, when samba is running as a standalone server, we must add an existing user to the samba database.

    The credentials of this user will be necessary to access the shared directory. For security reasons, it's a good practice to create a dedicated user for the task, omitting the creation of his home directory, and assigning him a fake shell:.
