Contact Methods for Traditional Clients
Traditional clients can communicate with the Uyuni Server using a range of methods.
The Uyuni daemon (
rhnsd) runs on traditional client systems and periodically connects with Uyuni to check for new updates and notifications.
Push via SSH is used in environments where clients cannot reach the Uyuni Server directly. In this environment, clients are located in a firewall-protected zone called a DMZ. No system within the DMZ is authorized to open a connection to the internal network, including the Uyuni Server.
OSAD is an alternative contact method between Uyuni and traditional clients. OSAD allows traditional clients to execute scheduled actions immediately.
Traditional clients will be deprecated with the next Uyuni version and will not be supported with future releases. Be aware that when migrating from traditional clients to Salt minions you do not have to delete the registered clients before. You can just register them as Salt minions and Salt will do the necessary steps with the traditional client. If you already deleted the traditional client and the registration as Salt minion is not possible anymore, see Troubleshooting.
