做渗透测试或提交漏洞单时，常常用到ping，来确认内外网IP，或者寻找资产的归属。

然而ping并不支持url parse。我们写个简单的extended ping脚本。

vim /usr/bin/eping

#!/usr/bin/env python

# Extented Ping

import sys
import urlparse
import platform
import os


if __name__ == '__main__':
    if len(sys.argv) == 1:
        print '  Usage: python %s URL' % sys.argv[0]
        sys.exit(0)
    target = sys.argv[1].lower()
    if not target.startswith('http'):
        target = 'http://%s' % target
    host = urlparse.urlparse(target, 'http').hostname
    param_count = '-c4 ' if platform.system() != 'Windows' else ''
    os.system('ping %s%s' % (param_count, host))

chmod +x /usr/bin/eping

Windows下使用pyinstaller生成一个exe文件，copy到C:\Windows\System32

pyinstaller –onefile eping.py
