<strong>Exceed</strong> <strong>onDemand</strong> 5 — A <strong>Technical</strong> <strong>Whitepaper</strong><br />
Figure 27 — Administrator can configure SSL settings in the Cluster Settings dialog box<br />
<strong>Exceed</strong> <strong>onDemand</strong> supports all ciphersuites that are available to OpenSSL 0.9.7e. When using<br />
ciphersuites that use the Digital Signature Standard (DSS), <strong>Exceed</strong> <strong>onDemand</strong> Client verifies the<br />
identity of the Server before establishing an SSL-encrypted session. Therefore the Server must<br />
have the private key file and certificate file. All flavors of <strong>Exceed</strong> <strong>onDemand</strong> Server come with<br />
the necessary utility to generate such files.<br />
Secure Shell<br />
While the implementation of SSL helps to secure the connections between <strong>Exceed</strong> <strong>onDemand</strong><br />
Client and <strong>Exceed</strong> <strong>onDemand</strong> Server, Secure Shell is used to secure the connections from the <strong>Exceed</strong><br />
<strong>onDemand</strong> Proxy to the host where the X applications reside. Secure Shell is an additional start<br />
method that is similar to other Remote command startup modes, such as Telnet, except it uses the<br />
SSH protocol and is able to offer strong security features that Telnet and other unsecured protocols<br />
cannot, namely encryption and X11 port forwarding.<br />
