A.2 Requirements

To set up SSL connections, you will need to download two programs in addition to Samba:


Eric Young's implementation of the Secure Socket's Layer (SSL) protocol as a series of Unix programming libraries

SSL Proxy

A freeware SSL application from Objective Development, which can be used to proxy a secure link on Unix or Windows NT platforms

These two products assist with the server and client side of the encrypted SSL connection. The SSLeay libraries are compiled and installed directly on the Unix system. SSL Proxy, on the other hand, can be downloaded and compiled (or downloaded in binary format) and located on the client side. If you intend to have a Windows NT client or a Samba client on the other end of the SSL connection, you will not require a special setup.

SSL Proxy, however, does not work on Windows 95/98 machines. Therefore, if you want to have a secure connection between a Samba server and Windows 95/98 client, you will need to place either a Unix server or a Windows NT machine on the same subnet with the Windows 9x clients and route all network connections through the SSL-Proxy-enabled machine. See Figure A.1.

Figure A.1

For the purposes of this chapter, we will create a simple SSL connection between the Samba server and a Windows NT client. This configuration can be used to set up more complex networks at the administrator's discretion.
