2.3.2. SGD Server Requirements for the SGD Gateway

The following requirements apply for the SGD servers used with the SGD Gateway:

• Secure mode. By default, the SGD Gateway uses secure connections to SGD servers. You must enable

secure connections on your SGD servers. Firewall forwarding must not be enabled.

In a standard installation, an SGD server is configured automatically to use secure connections.

• SGD version. The SGD servers must be running at least version 4.5 of SGD. It is best to use version

4.7 of the Gateway.

• Clock synchronization. It is important that the system clocks on the SGD servers and the SGD

Gateway are in synchronization. Use Network Time Protocol (NTP) software, or the rdate command, to

ensure that the clocks are synchronized.

2.3.3. Apache Web Server

The Apache web server supplied with the SGD Gateway is Apache version 2.2.22. It includes the standard

Apache modules for reverse proxying and load balancing. The modules are installed as Dynamic Shared

Object (DSO) modules.

2.3.4. Java Technology Version

The SGD Gateway includes Java Runtime Environment (JRE) version 1.6.0_33.

2.3.5. SSL Support

SSL support for the SGD Gateway is provided by the Java Runtime Environment (JRE) supplied with the

Gateway. See the Java Platform documentation for more details.

The SGD Gateway supports Privacy Enhanced Mail (PEM) Base 64-encoded X.509 certificates. These

certificates have the following structure:

-----BEGIN CERTIFICATE-----

...certificate...

-----END CERTIFICATE-----

The SGD Gateway supports the use of external hardware SSL accelerators, with additional configuration.

By default, the SGD Gateway is configured to support the following high grade cipher suites for SSL

connections:

• SSL_RSA_WITH_RC4_128_MD5

1 2 ... 18 19 20 21 22 23 24 25 26 27 28 ... 51 52
