We will a create simple ping program using Python in Kali Linux. Asking user to enter any IP address and pinging to that IP address to check reachability and displaying the result.
First of all, open Linux terminal and type nano followed by name of the file.
Our file name is ping_host.py
root@kali:~# nano ping_host.py
Now entering Python3 commands after moving into nano editor.
Importing OS module so that we can be able to run operating system commands, such as we use ping command from terminal in Kali Linux to know whether host is alive.
Asking user to enter IP Address using input() function
host = input('Please enter IP address : ')
Creating below variable and assigning complete command to it.
cmd = 'ping -c 1 ' + host
-c is the number of count. We are sending only single ICMP packet to destination.
Now using os.popen() function. This function takes OS command as the argument. We will be submitting Kali Linux terminal command which is assigned to cmd variable and using result variable to store the output. Below is the command.
result = os.popen(cmd)
Using for loop to print each line of result variable.
for line in result.readlines(): print(line)
Saving and exiting the editor.
Using below command at the terminal to run the file ping_host.py
root@kali:~# python3 ping_host.py
Below is the output.
