Hi All, I'm hoping you can help me with a more sysadmin type issue. Over the past few days we have been unable to maintain a responsive TDS server for 24 hours. The remedy is to restart tomcat and then we are good to go. In the past, I've had issues with foreign IP addresses scanning directories and initiating large NCSS downloads, but I've blocked everything outside of the US. Looking through the logs, I'm seeing mostly US Govt affiliated connections, and some ISP/AmazonCloud servers. I kinda sorta know how to use netstat, but I'm having trouble id'ing the culprit or the culprits. Admittedly, the hardware is old (soon to be replaced), but I have a hunch this is related to NCSS, since that was always the service that brought us down in the past. So, I was wondering if any of you can help with suggestions/best practices/tips that you use to monitor and secure your incoming connections with TDS. Thanks, Tom
