Such an attack can be used to gather information about a network before launching more sophisticated attacks. If a target host responds to the ping, its IP address is revealed to the attacker. By sending ICMP echo requests (pings) to multiple destination addresses, the attacker can determine which IP addresses are associated with active Internet Protocol (IP) endpoints. Using Ping Sweeps for Attack PurposesĪn attacker can use ping sweeps to identify active hosts on a network. Nmap can be used to perform a ping sweep of an entire subnet in order to quickly identify live hosts before performing more detailed scans. If an active host responds to the request, it indicates that the host is alive and reachable on the network. It works by sending ICMP Echo Request packets, commonly known as “pings”, to each IP address in the specified range.

That aid in the administration of local and remote systems named PsPing is part of a growing kit of Sysinternals command-line tools Simply add -u to have PsPing perform a UDPīandwidth test. Note that the test must run for at least one second after warmup for a IP address for 10 seconds and produces a histogram with 100 buckets. This command tests bandwidth to a PsPing server listening at the target Server, printing a histogram with 100 buckets when completed: psping -l 8k -n 10000 -h 100 192.168.2.2:5000 Measures the round trip latency of sending an 8KB packet to the target The -s option and the source address and port the server will bind to: psping -s 192.168.2.2:5000Ī buffer size is required to perform a TCP latency test.
