python-Monitoring Log Exercise

There is a access.log log, formatted as follows, with each line starting with an IP address:

1. Demand:

#1, if you access more than 200 times within the same IP address 60s, add IP to blacklist
#需求分析:
   #1, 60 seconds to read a file
   #2, split, take the first element, IP address
   #3, add all the IP to a list, if the IP number more than 200 times, blacklist

Import time
Point  = 0 #文件指针
While True:
   IPS = [] #存放所有的ip地址
   Blk_set = set () #存放需要加入黑名单ip
   With open (' Access.log ', encoding= ' utf-8 ') as F:
      F.seek (Point)
      For line in F:
         ip = line.split () [0]
         Ips.append (IP)
         #10.125.1.1
         If Ips.count (IP) >200:
            Blk_set.add (IP)
      For IP in Blk_set: #这里是因为防止ip重复加入黑名单 because the collection is de-heavy, there is no duplicate IP inside
         #os. System (' Jiaurru%s '%ip) #挨个将集合中的信息 blacklist
         Print (' Add blacklist%s '%ip)
      Point = F.tell ()
      Time.sleep (#隔30s) monitoring once
