nping Utility

• nping
  • an advanced network packet generation and testing tool
  • allows users to generate network packets of a wide range of protocols, letting them tune virtually any field of the protocol headers.
  • Require root privilege.

CMD	DESC
nping --icmp example.com	Test ICMP requests (default)
nping --tcp -p 80 example.com	Test http requests
nping --tcp -p 443 google.com	Test https requests
nping --udp -p 53 example.com	Test DNS requests
nping --arp 192.168.204.1	Send ARP requests (local network)
nping --icmp --count 5 example.com	Number of packets to send
nping --ttl 64 example.com	Set Time-To-Live value for packets
nping --rate 1000 example.com	Send num packets per second

• Example

nping --tcp-connect -p 80 --rate 10000 -c 50 dest_url
# --tcp-connect: TCP connect mode
# -p:   ports to connect to.
# -rate: the number of probes that Nping should send per second.
# -c: the number of times that Nping should loop over target hosts (and in some cases target ports).
