python发送以太网报文_Python原始套接字到以太网接口（Windows）
我正在尝试创建一个DHCP服务器，第一步是通过以太网端口发送数据包。我试图将数据包发送到我的以太网接口，但突然出现了一个错误。
代码如下。import socket
def sendeth(src, dst, eth_type, payload, interface = "eth0"):
"""Send raw Ethernet packet on interface."""
assert(len(src) == len(dst) == 6) # 48-bit ethernet addresses
assert(len(eth_type) == 2) # 16-bit ethernet type
#s = socket.socket(socket.AF_PACKET, socket.SOCK_RAW)
s = socket.socket(socket.AF_INET, socket.SOCK_RAW, socket.IPPROTO_RAW)
From the docs: "For raw packet
sockets the address is a tuple (ifname, proto [,pkttype [,hatype]])"
s.bind((interface, 0))
return s.send(src + dst + eth_type + payload)
if name == "main":
print("Sent %d-byte Ethernet packet on eth0" %
sendeth("\xFE\xED\xFA\xCE\xBE\xEF",
"\xFE\xED\xFA\xCE\xBE\xEF",
"\x7A\x05",
"hello"))
我对创建套接字的方式有问题。AF_包无法识别，所以我假设它只适用于Linux。我把它注释掉，在下面加了一行。我再次运行它，我开始得到一个错误如下所示。Traceback (most recent call last):
File "eth.py", line 27, in
"hello"))
File "eth.py", line 19, in sendeth
s.bind((interface, 0))
File "C:\Python27\lib\socket.py", line 224, in meth
return getattr(self._sock,name)(*args)
socket.gaierror: [Errno 11001] getaddrinfo failed
有人知道为什么会这样吗？
