Answer 1

在循环中使用file.readlines()。

因此，守则将是：

f=open('output2.txt','r')
c=f.readlines()
for i in c :
     print ("IP address of attacker is ", i)
f.close()

Answer 2

从文本文件中获取IP地址并进行检查。 See my code on git.

import socket
import re


f = open('ip_list.txt', 'r') #Text file with many ip address
o = f.read()
ip1 = re.findall( r"\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}", o )
hosts = ip1
ports = [80]
for host in hosts:
    for port in ports:
        try:
            s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
            s.settimeout(1)
            result = s.connect_ex((host, port))
            if result == 0:
                    print("  [*] Port " + str(port) + " open!" + host)
            else: print("[+] CLOSE HOST " + host + ":" + str(port))
        except:
            pass

Answer 3

import sys
import os 
import time 
b='sudo tshark -i ens33 -Y "tcp contains "attack"" -T fields -e ip.src -a duration:20>output2.txt' 
a=os.popen(b) 
time.sleep(22)
with open(output2.txt,"r") as f:
    ip=f.read.split('\n')
for Ip in ip:
    print "IP address of attacker is ", Ip

您必须在每个换行符处拆分文件内容。

Answer 4

最好使用'with'在自己的上下文中打开文件。这样，它将在到达最后一行后自动关闭。然后循环通过线条并在每行之前添加文本。此解决方案的另一个好处是您不必将所有IP保留在内存中。 IP将一次一个地流式传输。

如果没有找到ip，此代码也会打印一条消息。

with open('output2.txt','r') as f:
    ip_not_found = True
    for line in f:
        ip_not_found = False
        print "IP address of attacker is {IP}".format(IP=line)
    if ip_not_found:
        print 'no ip address was found'

Answer 5

import ipaddress

ip_address_file = open('ip.txt', 'r')  # open text file with ip addresses
for i in ip_address_file:  # loop through the ip text file
    i = i.strip()  # read each line
    try:
        i = ipaddress.ip_address(str(i)) #validates either ip is ipv4 or 6

    except ValueError:  #catch error for invalid ip format
        print('invalid ip '.format(i))
        continue   # if line empty continue with loop
