Data Collector Stops Collecting CDRs on Linux Based Collectors

Introduction

When a HP WXP Collaboration Data Collector running on a Linux server is restarted, the Call Detail Record (CDR) collection may stop. This issue occurs because the Linux firewall rules are not saved. After a system reboot, the firewall reverts to the last saved configuration, which may block CDR collection.

Resolution

To resolve this issue, save the required firewall rules so they persist after a reboot. On the Linux server hosting the Data Collector, run the following commands. The save option ensures that the firewall configuration is retained permanently.

sudo iptables -t nat -A PREROUTING -p tcp -m tcp --dport 21 -j REDIRECT --to-ports 2121
sudo service iptables save
