Python 扫描局域网存活设备 大无语了临近考试还在这里本末倒置的瞎搞！写这个没有什么技术含量的小工具，望各位大佬多担待一下。最近朋友的出租屋的网络出现多个DHCP服务器， 路由器有时候动态获取错误地址，所以使用 Python 编写了这个简单小工具以便了解局域网中哪些 IP 地址正在被使用和其主机名和MAC地址等信息（获取主机名和MAC还有点问题）。目前计划这个扫描工具实现以下功能：{timeline}{timeline-item color="#19be6b"}手动设置或者自动获取本地IP信息；{/timeline-item}{timeline-item color="#19be6b"}对指定或自动生成的子网内所有主机进行扫描，判断主机是否存活，并提取主机名、MAC地址和在线状态；{/timeline-item}{timeline-item color="#ed4014"}检测存活主机的端口使用状态；{/timeline-item}{timeline-item color="#ed4014"}手动设置检测超时时间；{/timeline-item}{timeline-item color="#ed4014"}手动设置线程；{/timeline-item}{/timeline}{lamp/}import ipaddress import socket import subprocess def scan_local_network(subnet=None): if subnet is None: local_ip = socket.gethostbyname(socket.gethostname()) subnet = ipaddress.ip_network(local_ip+'/24', strict=False) live_hosts = [] total_hosts = sum(1 for _ in subnet.hosts()) scanned_hosts = 0 for host in subnet.hosts(): scanned_hosts += 1 host = str(host) ping_process = subprocess.Popen(['ping', '-n', '1', '-w', '100', host], stdout=subprocess.PIPE, stderr=subprocess.PIPE) ping_output, _ = ping_process.communicate() if "TTL=" in ping_output.decode('gbk'): live_hosts.append((host, ping_output.decode('gbk'))) print(f"扫描进度：{scanned_hosts}/{total_hosts}", end='\r') return live_hosts def parse_ping_output(output): result = { "hostname": "", "mac_address": "", "status": "Offline" } # 提取主机名 for line in output.splitlines(): if line.startswith("Reply from"): hostname = line.split(" ")[2] result["hostname"] = hostname.replace(":", "") break # 提取 MAC 地址 for line in output.splitlines(): if line.startswith("MAC Address"): mac_address = line.split(":")[1].strip() result["mac_address"] = mac_address break # 判断端口状态 if "unreachable" not in output: result["status"] = "Online" return result def main(): # ASCII ascii_art = """ .--, .--, ( ( \.---./ ) ) '.__/o o\__.' {= ^ =} > - < / \\ // \\\\ //| . |\\\\ "'\ /'"_.-~^`'-. \ _ /--' ` ___)( )(___ (((__) (__))) ............................................. ping值稳定测精准 TanHaX 网络通畅似流云舒。 """ print(ascii_art) print("欢迎使用局域网IP扫描工具！") subnet = input("请输入要扫描的网段（例如 192.168.1.0/24），或 按回车键默认使用本地网段：") if subnet: try: subnet = ipaddress.ip_network(subnet, strict=False) live_hosts = scan_local_network(subnet) except ValueError: print("输入的网段格式不正确！") else: live_hosts = scan_local_network() if live_hosts: print("\n以下IP地址在使用中：") for host, output in live_hosts: parsed_data = parse_ping_output(output) print(f"[IP] {host} [Hostname] {parsed_data['hostname']} [MAC] {parsed_data['mac_address']} [Status] {parsed_data['status']}") print("扫描完成！") else: print("未发现任何活跃的主机。") if __name__ == "__main__": main()

使用 pyi-set_version 为 Python EXE 文件添加版本信息的方法 在开发软件时，为了方便用户了解软件的版本信息，我们通常会在软件的可执行文件（EXE 文件）中添加版本号等信息。而在 Python 开发中，我们可以使用 pyi-set_version 工具来为 EXE 文件添加版本信息。1. 要使用 pyi-set_version ，您需要先安装PyInstaller。您可以使用pip来安装它。在命Windows 终端(cmd)中输入以下命令：pip install pyinstaller2. 准备我们的 本版内容文件 可以引荐我之前的发布的模板 从 PyInstaller-pyi-grab_version 生成的可执行文件中提取版本信息3. 我们需要在 Windows终端 中进入您要添加版本的程序目录下，执行以下命令操作：pyi-set_version file_version_info.txt yourprogramname.exe打开程序的属性在详细信息就可以查看我们添加的版本信息了。

从 PyInstaller-pyi-grab_version 生成的可执行文件中提取版本信息 1. 要使用pyi-grab_version，您需要先安装PyInstaller。您可以使用pip来安装它。在Windows 终端(cmd)中输入以下命令：pip install pyinstaller2. 我们需要在 Windows终端 中进入您要获取版本的程序目录下，执行以下命令操作。pyi-grab_version yourprogramname.exe3.当命令执行完成后，会在目录下生成一个file_version_info.txt名称的文件。# UTF-8 # # For more details about fixed file info 'ffi' see: # http://msdn.microsoft.com/en-us/library/ms646997.aspx VSVersionInfo( ffi=FixedFileInfo( # filevers and prodvers should be always a tuple with four items: (1, 2, 3, 4) # Set not needed items to zero 0. filevers=(1, 0, 0, 0), prodvers=(1, 0, 0, 0), # Contains a bitmask that specifies the valid bits 'flags'r mask=0x16, # Contains a bitmask that specifies the Boolean attributes of the file. flags=0x0, # The operating system for which this file was designed. # 0x4 - NT and there is no need to change it.
