Working in a local area network , Many devices will be connected , The network device on the robot is 2 A the , A giant brother infrared , A Hikvision visible light . Robots have their own ip.
Sometimes robots hang too much , The equipment is under repair and replacement , I don't remember what happened ip What is it? , You can really scan it out with your own software , But it will take two windows Software in environment , time-consuming , Toss about . Just in linux, That's easy , Strike an order . nmap -P 192.168.1.0/24
You can scan it 192.168.1.0~192.168.1.255 All ip
But the premise is to install nmap
apt-get install nmap
But I always felt that I was beating mosquitoes with anti-aircraft guns —— overqualified
Then do it yourself python Well , So I copied and changed on the Internet .

thread modular , For Compatibility Use _thread Instead of , The safest use is to use threading modular datetime.datetime.now() Get the current time os = platform.system() Judge the current system type output = os.popen() Call the terminal , The return value is saved in output in python3 pingS.py 1
Parameters １ Is the specified network segment , If you want to scan 192.168.5.0~192.168.5.255
Then input. ：
python3 pingS.py 5
pyinstaller -F pingS.py Packaged into a single executable
Use the above command if... Is installed pyinstaller——-(pip intsall pyinstaller)
After running, a pingS The executable of
cp pingS /bin
Okay , To this step , Open the terminal input anywhere ：
pingS 1
All can be done 192.168.1.0~192.168.1.255 Scan
