Python script implementation of corporate office network IP paragraph usage

Because the company is using VMware virtualization technology, each time the virtual machine to allocate a connection to the external network IP address, in addition to the company scale, the new people also need to assign IP address, it is easy to cause the IP address of the bad and IP address conflict,

So we decided to use a script to troubleshoot the idle usage of IP, reduce the time cost of operations, and less IP collisions:

The script reads as follows:

If you want to use an IP address that can be modified to your own company:

#/usr/bin/env Python

#-*-conding:utf-8-*-

Import subprocess

Import threading

Import time

Import re

Ip_num = 256

List_ping_result = []

Class Pingthread (threading. Thread):

def __init__ (self, str_ip, Sleep_time, G_list_p_r):

Threading. Thread.__init__ (self)

Self.sleep_time = Sleep_time

SELF.STR_IP = Str_ip

Self.list_p_r = G_list_p_r

def run (self):

Time.sleep (Self.sleep_time)

Ftp_sub = subprocess. Popen ("Ping%s-n 3"% self.str_ip,

Stdin=subprocess. PIPE, Stdout=subprocess. PIPE, Shell=true)

ret = Ftp_sub.stdout.read ()

Str_ret = Ret.decode ("GBK")

ret_s = Re.search ("TTL", Str_ret)

If ret_s:

Self.list_p_r.append (' ping ok ', self.str_ip)

Else

Self.list_p_r.append (' ping error ', SELF.STR_IP)

def cmp_s (TOUPE_STR):

Str_val = toupe_str[1]

Ret_group = Re.match ("\d*", Str_val[::-1])

Str_ret = Ret_group.group ()

return int (str_ret[::-1])

thread_id = []

For I in Range (Ip_num):

Thread_id.append (0)

Thread_id[i] = Pingthread ("198.9.6.%d"% i, int (I/20), List_ping_result)

Thread_id[i].start ()

Print (I, end= ")

While True:

If Len (list_ping_result) >= Ip_num:

List_ping_result.sort (key=cmp_s)

For I in List_ping_result:

Print (i)

Break

The results are as follows:

Can be verified by a flat command:

Tested using 28 and 29IP:
