Contact Methods

There are a number of ways that the SUSE Manager Server can communicate with clients. Which one you use depends on your network architecture.

The SUSE Manager daemon (rhnsd) runs on traditional client systems and periodically connects with SUSE Manager to check for new updates and notifications. It does not apply to Salt clients.

Push via SSH and Push via Salt SSH are used in environments where clients cannot reach the SUSE Manager 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 SUSE Manager Server.

OSAD is an alternative contact method between SUSE Manager and its clients. OSAD allows registered client systems to execute scheduled actions immediately.
