The SunOS 4.x and Solaris 2.x operating systems from Sun Microsystems and the Kerberos Version 5 distribution from MIT are examples of systems which may be used to implement the scenario described above. Both systems from Sun Microsystems provide Secure RPC. In addition, Solaris 2.x provides Kerberos. The MIT Kerberos Version 5 distribution contains network service applications which use Kerberos for authentication and tools to develop such applications on Sun Systems and other Unix based systems. Remote login, remote execution, file transfer, and transparent file access can be provided with either Kerberos or Secure RPC in Solaris 2.x. These services, authenticated with Secure RPC, are provided in SunOS 4.x. How each of these services authenticated with Kerberos or Secure RPC are made available in each of the systems is summarized in table 10.1.
