If you're lucky to be working with a recent enough version of Red Hat Enterprise Linux (RHEL) – namely, anything after RHEL 5.7 and RHEL 6.1, then you should know what software subscriptions are and how to list them.
List active subscriptions in Red Hat
subscription-manager is a Linux command in RHEL, you run it with the list option to show what current subscriptions are active for your server.
Here's how this looks on my recently build RHEL8 beta virtual machine:
[root@rhel8 ~]# subscription-manager list +-------------------------------------------+ Installed Product Status +-------------------------------------------+ Product Name: Red Hat Enterprise Linux for x86_64 Beta Product ID: 486 Version: 8.0 Beta Arch: x86_64 Status: Subscribed Status Details: Starts: 23/11/18 Ends: 22/11/19
If you attempt running the same command as a regular user, you'll probably need to authenticate (tell the root password) first:
[greys@rhel8 ~]$ subscription-manager list You are attempting to run "subscription-manager" which requires administrative privileges, but more information is needed in order to do so. Authenticating as "root" Password: ...
List all the available subscriptions in Red Hat
It may well be that you have multiple subsriptions available as part of your setup – for instance, you might have additional software installed that is maintained and supported by Red Hat, but uses separate subscription channel instead of being supplied with the default OS one.
You can use the same subscription-manager command to list all the available subscriptions:
[root@rhel8 ~]# subscription-manager list --available +-------------------------------------------+ Available Subscriptions +-------------------------------------------+ Subscription Name: Red Hat Developer Subscription Provides: dotNET on RHEL Beta (for RHEL Server) Red Hat Enterprise Linux for SAP Red Hat Enterprise Linux Resilient Storage (for RHEL Server) Red Hat Ansible Engine RHEL for SAP HANA - Update Services for SAP Solutions Red Hat Enterprise Linux Scalable File System (for RHEL Server) - Extended Update Support RHEL for SAP HANA - Extended Update Support Red Hat Container Images Beta Red Hat Enterprise Linux Atomic Host Beta Red Hat Container Images Red Hat Enterprise Linux High Availability (for RHEL Server) - Extended Update Support Red Hat Enterprise Linux Load Balancer (for RHEL Server) Red Hat Container Development Kit Red Hat Beta Red Hat EUCJP Support (for RHEL Server) - Extended Update Support RHEL for SAP (for IBM Power LE) - Update Services for SAP Solutions MRG Realtime Red Hat Enterprise Linux Load Balancer (for RHEL Server) - Extended Update Support dotNET on RHEL (for RHEL Server) Red Hat Enterprise Linux High Availability - Update Services for SAP Solutions Oracle Java (for RHEL Server) Red Hat Enterprise Linux Server - Update Services for SAP Solutions Red Hat Software Collections (for RHEL Server) Red Hat Enterprise Linux for ARM 64 Red Hat Enterprise Linux High Availability (for RHEL Server) Red Hat Enterprise Linux High Performance Networking (for RHEL Server) Red Hat Enterprise Linux Scalable File System (for RHEL Server) Red Hat Enterprise Linux for Real Time Red Hat Enterprise Linux High Performance Networking (for RHEL Server) - Extended Update Support RHEL for SAP - Update Services for SAP Solutions Oracle Java (for RHEL Server) - Extended Update Support Red Hat Enterprise Linux Atomic Host Red Hat Enterprise Linux Server - Extended Update Support Red Hat Developer Tools (for RHEL Server) Red Hat Software Collections Beta (for RHEL Server) Red Hat Enterprise Linux Server Red Hat Developer Tools Beta (for RHEL Server) RHEL for SAP - Extended Update Support Red Hat Developer Toolset (for RHEL Server) Red Hat Enterprise Linux High Performance Networking (for RHEL Compute Node) Red Hat Enterprise Linux Resilient Storage (for RHEL Server) - Extended Update Support Red Hat Enterprise Linux for SAP Hana Red Hat S-JIS Support (for RHEL Server) - Extended Update Support SKU: RH00798 Contract: Pool ID: 8a85f99a65c8c8a1016698f9e87423fe Provides Management: No Available: 16 Suggested: 1 Service Level: Self-Support Service Type: Subscription Type: Standard Starts: 21/10/18 Ends: 21/10/19 System Type: Physical
Pretty impressive, isn't it? Can't wait to try some of these out, Red Hat Developer Tools, Red Hat Container Images and Red Hat Enterprise Linux High Availability all sound fun!
