IPアドレス設定をPython+tkinterにて

WindowsにてIPアドレス設定アプリケーションを、Python+tkinterにて実現してみた。ただし、機能不足（おそらく不具合も）があることに留意されたし。

まずは結論

起動すると、下記のように、ネットワークアダプタごとの情報が表示される。
一覧.png
アダプタを選択して、Editをクリックすると、下記のような編集（設定）画面となる。

方針

netshやPowershellのネットワーク系コマンドをSubprocessでハンドリングした方がEasyだったが、ここでは、pythonからWindowsの情報を取得できるWMI(Windows Management InstrumentationWindows Management Instrumentation)を利用。下記リンクなど参照。

ソースコード

Import

import wmi
import ctypes
import time
from socket import inet_aton
import tkinter as tk
from tkinter import messagebox

ここは説明なし。

WMIからの情報取得

### Network Adapter and Configuration List ###
AdapterList = []
NetConfList = []

### Network Interface Status ###
IF_State = ['Disabled', 'Connecting', 'Connected', 'Disconnecting', 'Hardware Not Present', \
            'Hardware Disabled', 'Hardware Malfunction', 'Disconnected', 'Media Disconnected', \
            'Authenticating', 'Authentication Succeeded', 'Authentication Failed', \
            'Invalid Address', 'Credentials Required']

### Get Network Interfaces ###
def Get_IF_Status():
    AdapterList.clear()
    EnabledAdapters = wmi.WMI().Win32_NetworkAdapter(NetEnabled=True)
    for adp in EnabledAdapters:
        AdapterList.append(adp)
    DisabledAdapters = wmi.WMI().Win32_NetworkAdapter(NetEnabled=False)
    for adp in DisabledAdapters:
        AdapterList.append(adp)
    NetConfList.clear()
    for i in range(len(AdapterList)):
        netif = wmi.WMI().Win32_NetworkAdapterConfiguration(InterfaceIndex=AdapterList[i].InterfaceIndex)
        NetConfList.append(netif)

WMIの情報は下記参照。

少々説明。

  • IF_Stateはネットワークアダプタの状態（上記リンクの情報）をあらわす。
  • インストールされているアダプタの内、NetEnabledに値（True or False）を持つものだけを対象とする。
  • アダプタ情報をAdapterListに、IP関連情報をNetConfListに格納。

IPアドレス情報の確認

### Exsitence of Address Information ###
def IPaddrStr(idx):
    if NetConfList[idx][0].IPAddress is not None:
        str = NetConfList[idx][0].IPAddress[0]
    else:
        str = ''
    return str

def NetmaskStr(idx):
    try:
        str = NetConfList[idx][0].IPSubnet[0]
    except:
        str = ''
    return str

def GatewayStr(idx):
    try:
        str = NetConfList[idx][0].DefaultIPGateway[0]
    except:
        str = ''
    return str

def DNS1Str(idx):
    try:
        str = NetConfList[idx][0].DNSServerSearchOrder[0]
    except:
        str = ''
    return str

def DNS2Str(idx):
    try:
        str = NetConfList[idx][0].DNSServerSearchOrder[1]
    except:
        str = ''
    return str
  • IP関連情報からアドレスなどを文字列化。
  • 情報がない時は、空文字列をリターン。
    • 情報なしチェックは、「not None」か「try except」を利用。

IPアドレスチェック

### Check IP Address Format ###
def is_valid_ip(addr, flag):
    if (len(addr) == 0) and flag:
        return True
    try:
        inet_aton(addr)
        return True
    except:
        return False

記事「PythonでIPアドレスの文字列表現が正しいフォーマットか確認する」を内容を少々アレンジし、入力値がなくてもフラグがTrueのときは正常とした（後述）。

  • 管理者権限チェック、権限無し時にはメッセージを表示し、クローズ。
  • NetConnectionStatus（Win32_NetworkAdapter クラス）の値が0以外でアダプタが有効化されており、0で無効化されている。
    • 有効状態から無効に変更されたときは、メソッドDisable()をCallしリターン。
    • 無効状態から有効に変更されたときは、メソッドEnaable()をCall。有効化には時間がかかるようなので、5秒程待つ。
  • DHCPによるIPアドレス取得（dhcpState.get() == True）、かつ、現在の状態が固定IPアドレス設定（DHCPEnabled == False）
    • 現在のIPアドレスをGatewayに設定するとGateway設定がクリア（Win32_NetworkAdapterConfigurationクラス記載より）。
      • ただし不具合があるようで、アダプタの無効化→有効化しないと完全にはクリアされないようだ。
    • DNSサーバーアドレスの削除。
    • DHCPによるIPアドレス取得有効化（EnableDHCP()）。
  • 無効なIPアドレス形式入力時にはメッセージを表示。
    • ただし、DHCPからIPアドレス取得時のIPアドレスなどの空入力はOKとしている。
  • 固定IPアドレス設定時には、EnableStatic()およびSetGateways()により、アドレスを設定する。
  • DNSサーバーaddressを適宜設定する（1stが未入力の場合は2ndの入力があっても無視している）。
  • ダイアログボックスのクローズ。
