What best practices and preventative measures can help avoid the recurrence of 'Hercules TCP error 10061'?

To prevent recurrence of TCP error 10061: 1. **Consistent Configuration:** Maintain well-documented and consistent IP addresses and port numbers for all Hercules and connected services. 2. **Automated Service Management:** Ensure critical network services that Hercules relies on (e.g., TN3270 servers, CTCI partners) are configured to start automatically and reliably on system boot. 3. **Careful Firewall Management:** Implement precise firewall rules, avoiding overly permissive or restrictive settings. Regularly review and update these rules as your network configuration changes. 4. **Port Availability Checks:** Before starting Hercules or a related service, ensure the required ports are free using `netstat`. 5. **Error Logging:** Enable verbose logging for Hercules and connected applications to capture early warning signs or detailed error messages that precede a 10061 error. 6. **Dedicated IP/Ports:** If possible, assign dedicated IP addresses or specific port ranges for Hercules components to minimize conflicts.
