I confirm this on 8.x. I do not think there is any easy to change it. The best bet is to probably open support case and try to convert it into change request. ________________________________________ From: toasters-bounces@teaparty.net [toasters-bounces@teaparty.net] On Behalf Of Jan-Pieter Cornet [johnpc@xs4all.nl] Sent: Wednesday, May 02, 2012 19:26 To: David.Lee@ecmwf.int Cc: toasters@teaparty.net Subject: Re: Getting a quick "connection refused"
FYI. I tried replicating in my environment, and our toaster returns an immediate 'connection refused' for any portnumber, above or below 1024, doesn't matter.
Are you sure you aren't talking to some default firewall somewhere? Maybe run a test from a host that is connected to the same VLAN as the toaster.
(Ontap 7.3.6, if that matters).

Here the behaviors of a handful of operating systems: Windows: Silence for both upper and lower ports Linux/Solaris/OpenVMS: TCP RSTs for both upper and lower ports ONTAP: TCP RSTs for upper ports; Silence for lower ports
So, I think your question can be refined as follows: Is there an Option which changes the TCP stack's behavior, such that it issues a TCP RST for all TCP Ports (on which no daemon is listening), not just for the upper ports?

A TCP connection towards an arbitrary high port number (>=1024) on the NetApp seems to return "connection refused" instantly.
By contrast, a connection towards a low port number waits for several minutes, then something times out. I imagine this is related to assisting security etc.
