Non-RHCOS enabled locations in Sydney

The following network requirements are for outbound connectivity for Red Hat Enterprise Linux (RHEL) hosts for use with non Red Hat CoreOS enabled locations in the Sydney (au-syd) region.

The type of location that you create dictates the type of operating systems that can run on your hosts. If your location is RHCOS enabled, then you can attach hosts that are running either RHEL and RHCOS. If your location isn't RHCOS enabled, then you can attach only hosts that are running RHEL. You can check whether your location is RHCOS enabled. For more information about operating system support, see Planning your operating system.

You can verify your host setup with the satellite-host-check script. For more information, see Checking your host setup.

You can download a copy of these requirements.

Review the following outbound network requirements for RHEL hosts for use with non-RHCOS enabled locations in the Sydney (au-syd) region.

Destination hostnames: c-01-ws.au-syd.link.satellite.cloud.ibm.com, api.link.satellite.cloud.ibm.com
Protocol and ports: HTTPS 443

You can find the hostnames or IP addresses by running the dig c-<XX>-ws.au-syd.link.satellite.cloud.ibm.com +short command. Replace <XX> with 01, 02, and so on, until no DNS results are returned.

Allow hosts to be attached to a location and assigned to services in the location.

Destination IP addresses: 130.198.66.26, 135.90.69.66, 168.1.8.195, 104.94.220.125, 104.94.221.125, 104.94.222.133, 104.94.223.133, 104.96.176.125, 104.96.177.125, 104.96.178.127, 104.96.179.127, 104.96.180.124, 104.96.181.124
