SynopsisIt was possible to identify the status of the remote host (alive or dead).
DescriptionNessus was able to determine if the remote host is alive using one or more of the following ping types :
- An ARP ping, provided the host is on the local subnet and Nessus is running over Ethernet.
- An ICMP ping.
- A TCP ping, in which the plugin sends to the remote host a packet with the flag SYN, and the host will reply with a RST or a SYN/ACK.
- A UDP ping (e.g., DNS, RPC, and NTP).
