Echo Service Detection

Info Nessus Plugin ID 10061


An echo service is running on the remote host.


The remote host is running the 'echo' service. This service echoes any data which is sent to it. This service is unused these days, so it is strongly advised that you disable it, as it may be used by attackers to set up denial of services attacks against this host.


- Under Unix systems, comment out the 'echo' 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\EnableTcpEcho HKLM\System\CurrentControlSet\Services\SimpTCP\Parameters\EnableUdpEcho Then launch cmd.exe and type :

net stop simptcp net start simptcp To restart the service.
