In-Reply-To: <5.1.0.14.0.20021002130602.0399e3e8@mail.stdnet.com> I've emailed Jonathan privately, but I'll post here as well in case others have experienced this as well. I'm one of the lead security engineers for the ClearPath MCP environment (NX, LX, etc), and have run security scanners against the MCP environment dating back to the MCP 5.0 software release. I've just completed running them against the MCP 8.0 networking release, and have never experienced a fatal system error because of them. Excessive logging, yes, since the current design does log an entry for each "SYN received for unknown port" that occurs into the system sumlog. I'd like to get some more detailed information about this so that we can see what can be done to help and clarify what is being seen. Please contact me directly.
