Issue/Introduction

When trying to configure HTTPS with 23.3.11, we are unable to connect to the Data Agrgegator

The following error is seen in the DA's /opt/IMDataAggregator/apache-karaf/data/log/karaf.log:

Unable to start Pax Web server: Failed to bind to @LISTENING_ADDRESSES@/<unresolved>:8582
java.io.IOException: Failed to bind to @LISTENING_ADDRESSES@/<unresolved>:8582

Environment

DX NetOps Performance Management 23.3.11

Resolution

Modify jetty.xml, located by default in /opt/IMDataAggregator/apache-karaf/etc

On lines 149 and 150 you will find:

149         <Set name="name">@LISTENING_ADDRESSES@:<Property name="https.port" default="8582" /></Set>
150         <Set name="host"><Property name="jetty.host" default="@LISTENING_ADDRESSES@" /></Set>

 

They need to be altered to:

149         <Set name="name">0.0.0.0:<Property name="https.port" default="8582" /></Set>
150         <Set name="host"><Property name="jetty.host"  /></Set>

 

1. Changing @LISTENING_ADDRESSES@ to 0.0.0.0 and ensuring the trailing : is kept
2. Removing default="@LISTENING_ADDRESSES@" entirely

 

Once this is accomplished, restart the dadaemon service:

systemctl restart dadaemon
