The only difference is that ping sweeping is the procedure to find more than one machine availability in specific network range. Concept of Ping SweepĪctually in one or other sense, ping sweep is also known as ping sweeping. The above process of sending ICMP request is also called ping scan, which is provided by the operating system’s ping command. It involves sending an ICMP ECHO Request to a host and if that host is live, it will return an ICMP ECHO Reply. This scan is useful when we have to check a number of live hosts in a network. ICMP is not a port scan but it is used to ping the remote host to check if the host is up. Port Scanner using ICMP (Live hosts in a network) We can change this range and can check for other ports. The output shows that in the range of 50 to 500 (as provided in the script), this port scanner found two ports - port 135 and 445, open. The above script generates the following output − That is why it is advisable to use port scanner on localhost or your own website (if any).
Port scanning is akin to going to someone’s house and checking their doors and windows. We should never execute a port scanner against any website or IP address without explicit, written permission from the owner of the server or computer that you are targeting. When we run the above script, it will prompt for the hostname, you can provide any hostname like name of any website but be careful because port scanning can be seen as, or construed as, a crime. Print('Time taken:', time.time() - startTime) Target = input('Enter the host to be scanned: ') Following is a Python script for port scanner using socket − Now, we will build a simple port scanner using socket. In our previous chapter, we discussed what a socket is. User or registered ports: from 1024 to 49151 System or well-known ports: from 0 to 1023 These 65535 ports can be divided into the following three ranges − As it always advisable to close unnecessary ports of our system hence essentially, there are more than 65000 doors (ports) to lock. Both of the protocols have 0 to 65535 ports. As discussed earlier, TCP/IP protocol suite, use for communication over internet, is made up of two protocols namely TCP and UDP. Port scanning is just like a thief who wants to enter into a house by checking every door and window to see which ones are open.

Information about OS and MAC address of the target host. Information about the services running on each port. Now, consider the information we can get after running the port scan − We can configure the port scanner according to our requirements to get maximum information from the target system.
Network administrator, penetration tester or a hacker can use this technique. Port scanning may be defined as a surveillance technique, which is used in order to locate the open ports available on a particular host.
