Here's an example of sending 3 TCP syn packets to port 80 of scanme.nmap.org: # nping -tcp -c3 -p 80 scanme.nmap.org Starting Nping 0.7.40 ( https://nmap.org/nping ) at 2017-08-27 22:28 PDT SENT (0.0456s) TCP 192.168.0.108:49232 > 45.33.32.156:80 S ttl=64 id=9502 iplen=40 seq=1975150814 win=1480 RCVD (0.2278s) TCP 45.33.32.156:80 > 192.168.0.108:49232 SA ttl=52 id=0 iplen=44 seq=3623470103 win=29200 <mss 1460> SENT (1.0459s) TCP 192.168.0.108:49232 > 45.33.32.156:80 S ttl=64 id=9502 iplen=40 seq=1975150814 win=1480 RCVD (1.2477s) TCP 45.33.32.156:80 > 192.168.0.108:49232 SA ttl=52 id=0 iplen=44 seq=3639139057 win=29200 <mss 1460> SENT (2.0478s) TCP 192.168.0.108:49232 > 45.33.32.156:80 S ttl=64 id=9502 iplen=40 seq=1975150814 win=1480 RCVD (2.2678s) TCP 45.33.32.156:80 > 192.168.0.108:49232 SA ttl=52 id=0 iplen=44 seq=3654733783 win=29200 <mss 1460> Max rtt: 219.887ms | Min rtt: 182.099ms | Avg rtt: 201.251ms Raw packets sent: 3 (120B) | Rcvd: 3 (138B) | Lost: 0 (0.00%) Nping done: 1 IP address pinged in 2.32 seconds If you want to send the packets indefinitely, use -c0.
