rhnsd is a client-side daemon for traditional clients only. As of SUSE Manager 4, it is only available on non-systemd systems (SUSE Linux Enterprise 11 and Red Hat Enterprise Linux Server 6). For later versions, a systemd timer (rhnsd.timer) is available.


rhnsd is a primary component of SUSE Manager. It performs the following functions in the stack.

  • Client-side daemon for traditional clients

  • Periodically calls mgr_check (symlinked to rhn_check)

  • Randomizes check time not to overload the server
