Contact Methods for Traditional Clients

Traditional clients can communicate with the SUSE Manager Server using a range of methods.

The SUSE Manager daemon (rhnsd) runs on traditional client systems and periodically connects with SUSE Manager to check for new updates and notifications.

Push via SSH is 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 traditional clients. OSAD allows traditional clients to execute scheduled actions immediately.
