Custom internal communication

Introduction

This procedure describes how to configure an alternative communication path between the nGeniusONE server and the InfiniStream. This procedure can also be used for vStream.

 

Procedure

Step 1:

Log into the nGeniusONE server and stop all nGenius processes

# cd /opt/NetScout/rtm/bin
# ./stop

Log into the InfiniStream and stop all nGenius processes

# isbin
# ./stopall

Step 2:

Drill a hole into the local firewall that is running on the InfiniStream. There are many different ways to accomplish this task. The below suggestion is a 'quick and dirty' one but it works well. Insert the following line in the iptables configuration file, just before the REJECT rule. Port TCP/7443 is the custom port that we are using

# vi /etc/sysconfig/iptables

-A INPUT -p tcp -m state --state NEW -m tcp --dport 7443 -j ACCEPT

# service iptables restart

Step 3:

Log into the InfiniStream and alter the 'NSPROCPORT_SECURED' directive.

# isbin
# vi procmanager.env

NSPROCPORT_SECURED=7443

Step 4:

Log into nGeniusONE server using the web browser.

1. Launch module "Device Configuration"
2. Select the corresponding InfiniStream
3. Change Communication Protocol to 'HTTPS'
4. Change HTTP/HTTPS Port to '7443'

 

Step 5:

Log into the nGeniusONE server using ssh and alter the serverprivate.properties and append the following line:

 

device.<InfiniStream_IP_address>.procman.port=7443

This approach gives the flexibility to use different TCP ports amongst the various InfiniStreams that are part of the distributed environment.

 

In case the use of this particular custom port is required for every InfiniStream please use the following line:

BaseEngineManager.ssl.port=7443

# cd /opt/NetScout/rtm/bin
# vi serverprivate.properties

 

Step 6:

Reboot both the InfiniStream and nGO server and relearn the InfiniStream using the module Device Confiugaration.
