On Open Enterprise Server (OES) servers, the NetWare Core Protocol (NCP) Server provides the same services that are available with NCP Server on NetWare. With NCP Server, you can define NCP volumes (NCP shares on Linux POSIX file systems) and use OES Storage Services (NSS) volumes on Linux. Access to both types of volumes is controlled by using the OES trustee model. Windows and Linux workstations running Client for Open Enterprise Server software can access data and manage file sharing on OES servers just as they do on NetWare servers.
