UDP tuning and monitoring
Also, any hints on monitoring UDP. Is there a way to see packet counters for a specific interface rather than for all of TCP/IP?
Any suggestions would be great! Thanks.

Re: UDP tuning and monitoring
Google kicks over a few similar discussions, based on some keyword searches -- though none exactly specific to OpenVMS. (I'd expect to find these recommendations from Oracle.)
I tend to use out-board monitors for network traffic analysis. Check snort or such. Most of these tools can be configured on most any handy Windows, Linux or Mac OS X box, and for little or no money, and will provide you with details of what your network is doing.
This also avoids loading stuff onto the server.

Re: UDP tuning and monitoring
I agree with Hoff, an outboard monitor is the correct way to go, as a starting point. Always to science.
Ethereal (now WireShark) is available as freeware and quite usable (see http://www.wireshark.org ). I would isolate the traffic that is relevant and make sure that I do reliable experiments. Be careful of other devices in the path, they will likely have a significant impact.

Re: UDP tuning and monitoring
I neglected to mention this is on a VMS system, so that definitely seems to mean Wireshark would be running on another server.
