As a worker , especially 996,、007 The job of , Besides cooking , The most intense and exciting thing is to sneak away occasionally at work , Go and fish in the pond .
What fish do ordinary people touch ？ Chat 、 Microblogging 、 WeChat friend circle 、 Little games 、 A novel 、 Stock funds, etc .
What is the biggest obstacle to fishing ？ Of course, the contractor （ Boss ） 了 , They want workers 24 Work hour after hour .
But human energy is limited , You can only concentrate on a few hours a day , Other times need to be adjusted by fishing , So as long as we fish without being found by the contractor , That's quite a pleasant thing .
So , I use Python I wrote a little tool ——BOSS coming , To monitor the boss , Reduce the probability of catching fish .
We know , Each computer or mobile phone terminal has a fixed Mac Address , And our company has several office areas AP , Everyone's mobile phone is connected to the nearest one AP , So in theory, if I know the owner's mobile phone Mac Address , Then scan the LAN for all Mac Address , If the boss's mobile phone appears Mac Address , So the boss is probably near me , Fishing is dangerous at this time ; If there is no boss Mac Address , Then the boss may be far away from me , It's safer to fish at this time .
Based on the above ideas , All I have to do is get the boss's mobile phone Mac Address , All LANs are polled continuously Mac Address , Once the boss's mobile phone appears Mac Address , I'll work honestly , Once the boss Mac The address disappeared , You can fish .
How to get the boss's mobile phone Mac Address ？
Many people may feel hopeless when they hear this ！ You can't steal the boss's mobile phone , Then go to the settings to find it .
Heaven never shuts one door but opens another , As long as you use your head , There are many ways ！
My approach is this . When other colleagues don't move , When the boss comes , Save the LAN once Mac Address information , Save it again when the boss leaves , And then compare them , Find out the owner's mobile phone Mac Address . To ensure accuracy , Try it a few more times .
First step , Use ipconfig/all command , You can find the current network segment ：
The second step , Use the polling command one by one ping In a segment IP , This step is to establish ARP surface . The order is as follows ：
for /L %i IN (1,1,254) DO ping -w 1 -n 1 192.168.1.%i
among ,192.168.1.%i Is the network segment to query .
The third step , Use arp Command can query all Mac Address , The order is ：
arp -a
After running , You will see results similar to the following ：
<figcaption >mac Address list </figcaption>
The idea has been verified , The preparations have been made , Next is the code implementation .
First , We follow the above ideas , First write a to get all the information on the LAN Mac Address method .
def get_macs():
# function cmd Control window , Input “arp -a”, And deliver the content to res in
res = os.popen("arp -a")
# Read res data , Convert to readable data
arps = res.read()
print(arps)
# What will be obtained counts The data in is based on “ A newline ” To split and slice
result = arps.split('\n')
# Set an empty list to load ip
ips = []
# Set an empty list to load mac
macs = []
# Traverse
for i in range(1, len(result)):
# Get... In the list idx Data
line = result[i]
if ('Internet' in line) | ('' == line) | (' Interface ' in line):
continue
# according to “ ” Slice
line_split = line.split(" ")
index = 0
for l in line_split:
if l != '':
index += 1
if index == 1:
ips.append(l)
elif index == 2:
macs.append(l)
return ips, macsthen , Write a timed poll .
# Boss's Mac Address bossMac = "01-00-5e-0b-14-01" sleep_time = 5 while 1 == 1: time.sleep(sleep_time) ips, macs = get_macs() is_come = 0 for mac in macs: if mac == bossMac: is_come = 2 # If boss coming , Every other day 5 Scan every minute sleep_time = 300 # Prompt alarm choice = g.msgbox(msg=" There's an inner ghost , Terminate the transaction ！", title="OMG") break if is_come == 0: # If boss go , Every other day 5 Scan every second sleep_time = 5 g.msgbox(msg=" Everything is all right ！", title="OMG")
What I'm setting here is ： If the boss shows up , Every other day 5 Poll every minute , Because if the boss is here , Concentrate on your work , Don't think about fishing too often . If the boss leaves , Every other day 5 Poll every second , It's better to give frequent early warning when fishing ！
Run the program , When the boss comes , The warning pop-up window is like this ：
When the boss disappears , The content of the pop-up window is like this ：
Of course , If the boss doesn't drive WiFi , Then this method fails . Or the boss comes , however The response of the mobile phone is slow , Didn't switch to this side AP , There will also be danger . So don't rely entirely on this gadget , When fishing, you should occasionally observe the surrounding environment .
