Hello,

Today, I  would like to share with you the nmap test.


  • -A comprehensive/comprehensive scan, the scan time is slow, you can specify ip/host, network segment scan:

nmap -A 192.168.10.102

Use the option --packet-trace to see the scanning process. The source host will initiate a TCP connection request to many ports of the target host. If the target host responds, the target host is online. During the test, it was found that the scan results sometimes succeeded and sometimes failed, until the reason. Please know the senior guidance.

The scan results show that the host is not up

44444

Scanning again shows that the host is online


TRACEROUTE 

HOP      RTT         ADDRESS

1       3.18ms       192.168.10.102

OS and Service detection performed. Please report any incorrect result at http://nmap.org/submit/.

Nmap done: 1 IP address (1 host up)  scanned in 93.49 seconds


  • -sP/-sn Ping scan, only ping scan

Send Arp request

ccccccc


  • -P0[protocal list] IP protocol ping

The source host initiates a TCP handshake connection request for many ports to the target host. If a response is returned, the target host is online.


When no protocol is specified, TCP, UDP, and ICMP are used by default. 

User Datagram Protocol (UDP) is a communications protocol that is primarily used to establish low-latency and loss-tolerating connections between applications on the internet. UDP speeds up transmissions by enabling the transfer of data before an agreement is provided by the receiving party.

The Internet Control Message Protocol (ICMP) is a protocol that devices within a network use to communicate problems with data transmission. In this ICMP definition, one of the primary ways in which ICMP is used is to determine if data is getting to its destination and at the right time.


The protocol can also use numbers. The value corresponds to the value of the protocol field in the header of the IP data packet: 1-ICMP, 2-IGMP, 6-TCP, 17-UDP


ppppppp 

  • -PS TCP SYN ping scan

Send a TCP SYN connection establishment request to the port of the target host

  • -PA TCP ACK ping scan

Send a TCP ACK to the target host port. Use this scan to detect hosts that block SYN packets or ICMP Echo. Send an ACK-identified packet to the target host. If the host is not online, there will be no response. If the host is online, it will return an RST packet.

  • -PU UDP ping
