'''
不同平台,实现对所在内网端的ip扫描
有时候需要知道所在局域网的有效ip,但是又不想找特定的工具来扫描。
使用方法 python ip_scaner.py 192.168.1.1
(会扫描192.168.1.1-255的ip)
'''

get os 类型

if os == "Windows":
return "n"
else:
return "c"

cmd = ["ping", "-{op}".format(op=get_os()),
"1", ip_str]
output = os.popen(" ".join(cmd)).readlines()
flag = False
for line in list(output):
if not line:
continue
if str(line).upper().find("TTL") >=0:
flag = True
break
if flag:
print "ip: %s is ok ***"%ip_str

给出当前的127.0.0 ,然后扫描整个段所有地址
'''
