Description:

The remote host is running a 'discard' service. This service
typically sets up a listening socket and will ignore all the
data which it receives.

This service is unused these days, so it is advised that you
disable it.


Solution :

- Under Unix systems, comment out the 'discard' line in /etc/inetd.conf
and restart the inetd process

- Under Windows systems, set the following registry key to 0 :
HKLM\System\CurrentControlSet\Services\SimpTCP\Parameters\EnableTcpDiscard

Then launch cmd.exe and type :

net stop simptcp
net start simptcp

To restart the service.


Risk factor : Low
