Getting a quick "connection refused"
|
|
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.
As part of our transition from our previous non-NetApp fileserver, it
would be very useful if we could persuade the NetApp to return a quick
"connection refused" on a particular low port number. But we cannot see
a way to adjust this behaviour (either for a particular low port or for
all low ports). Is this possible? If so, could you point us to the
relevant documentation, please?
(If it is not possible, we can probably put a workaround in the external
application.)
