Overview

Each time the Customer Premise Equipment (CPE) contacts the Front-end Server, Java errors mentioned, are raised:

2015-03-06 09:35:57,078 [62.167.34.8] INFO ACS - IP: null, CPE: c0b05c26c4e733c28ed2ea23bdace144, Received: Inform , Event: 0 BOOTSTRAP
2015-03-06 09:35:57,357 [62.167.34.8] ERROR ACS - Unexpected error occurred java.lang.IllegalArgumentException: Invalid IP address java.lang.IllegalArgumentException: Invalid IP address

Environment

• Solaris 10
• Oracle 10g
• jboss4.0.4.GA
• Apache-5.5.25

Root Cause

The root cause of the failure is the Auto-Configuration Server (ACS) does not have the IP-Address of Customer Premise Equipment (CPE), as the DeviceIPAddressSource is not using the Connection Request URL.

Resolution

To solve the issue mentioned previously, On the front_end within the tomcat service folders, a setting in ACS.properties called DeviceAddressSource needs an extra search string.

To update the settings, replace the following string:

DeviceIPAddressSource=EXTERNAL_IP_ADDRESS

in ACS.properties files for both ACS-server and ACS-API, with:

DeviceIPAddressSource=EXTERNAL_IP_ADDRESS,CONNECTION_REQUEST_URL

To update the settings, follow the steps mentioned below:

1. Modify the ACS.properties file on ACS-server:

   1. Navigate to the folder:

      tomcat_home_dir/webapps-acs/ACS-server/

   2. Copy ACS.properties to ACS.properties.<timestamp>-acs using the below command:

      cp ACS.properties ACS.properties.<timestamp>-acs

   3. Edit ACS.properties file using the vi editor (or any other preferred editor):

      vi ACS.properties

   4. Replace

      DeviceIPAddressSource=EXTERNAL_IP_ADDRESS 

      with

      DeviceIPAddressSource=EXTERNAL_IP_ADDRESS,CONNECTION_REQUEST_URL

   5. Save the file.

   6. Move ACS.properties.<timestamp>-acs using the following command:

      mv ACS.properties.<timestamp>-acs /<home_dir>

2. Modify the ACS.properties file in ACS-api:

   1. Navigate to the folder:

      tomcat_home_dir/webapps-api/ACS-api/

   2. Copy ACS.properties to ACS.properties.<timestamp>-acs using the below command:

      cp ACS.properties ACS.properties.<timestamp>-acs

   3. Edit ACS.properties file using the vi editor (or any other preferred editor):

      vi ACS.properties

   4. Replace

      DeviceIPAddressSource=EXTERNAL_IP_ADDRESS 

      with

      DeviceIPAddressSource=EXTERNAL_IP_ADDRESS,CONNECTION_REQUEST_URL

   5. Save the file.

   6. Move ACS.properties.<timestamp>-acs using the following command

      mv ACS.properties.<timestamp>-acs /<home_dir>

3. Rebuild both ACS-server.war and ACS-api.war with the updated ACS.properties files:

   1. Navigate to the folder:

      tomcat_home_dir/webapps-api/ACS-server/

   2. Create the war file with updated properties using the command below:

      jar uf ../ACS-api.war ACS.properties

   3. Navigate to the folder:

      tomcat_home_dir/webapps-api/ACS-api/

   4. Create the war file with updated properties using the command below:

      jar uf ../ACS-api.war ACS.properties

4. Restart Tomcat Service.

Confirmation

After implementing the steps detailed previously and restarting the Tomcat Service, CPE connects with the front end, without raising any error.
