ECHO: No Response From Server
This protocol anomaly triggers when it detects excessive ECHO client-to-server data that the server does not reply to. This can indicate a hung server or data tunneling over ECHO packets.
Extended Description
The presence of multiple client to Echo server transmissions with no response could indicate a network configuration error, a tunneling attempt, or an Echo server crash..
