The output from the NETSTAT DOS command was: netstat dos VM TCP/IP Netstat Level 530 Maximum Number of Half Open Connections: 258 Denial of service attacks: Attacks Elapsed Attack Attack IP Address Detected Time Duration -------- --------------------------------------- --------- --------- --------- Smurf-IC 10.17.2.5 210 0:04:46 0:04:45 Does anyone know what this means and if it is a real problem? It looks like the ATTACKS number is rising quickly.
