Echo Service Detection
Info Nessus Plugin ID 10061
SynopsisAn echo service is running on the remote host.
DescriptionThe 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.
Solution- 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.
