Configuring the eStreamer Reference Client

Chapter 6

Configuring Communications for the eStreamer Reference Client

The reference client uses the Secure Sockets Layer (SSL) for data 

communication. You must install OpenSSL on the computer you plan to use as a 

client and configure it appropriately for your environment.

For initial installations on Linux operating systems, you must install 

the 

libssl-dev 

component as part of this download.

To set up SSL on your client:

1. Download OpenSSL from 

2. Unpack the source to 

/usr/local/src

.

3. Configure the source by running the Configure script.
4. Make and install the compiled source.

Loading General Prerequisites for the Perl Reference Client

Before you can run the eStreamer Perl reference client, you must install the 

IO::Socket::SSL

 Perl module on the client computer. You can install the module 

manually or use 

cpan

 to do so.

If the 

Net::SSLeay

 module is not installed on the client computer, 

install that module as well. 

Net::SSLeay

 is required for communication with 

OpenSSL.

You also need to install and configure OpenSSL to support an SSL connection to 

the eStreamer server. For more information, see 

Loading Prerequisites for the Perl SNMP Reference Client

Before you can run the Estreamer SNMP module of the Perl reference client, you 

must install the latest 

net-snmp

 Perl modules available for the client operating 

system on the client computer.

Downloading and Unpacking the Perl Reference Client

You can download the 

EventStreamerSDK.zip

 file that contains the eStreamer 

Perl reference client from 

.

Unpack the zip file to a computer running the Linux operating system, where you 

plan to run the client.
