0.0.0.0(INADDR_ANY)是“任何”地址(不可路由的元地址)。这是一种指定“任何IPv4接口”的方法。 这意味着,所有的接口都侦听端口12345
要列出所有网络接口,我会建议使用像this
库如果你使用Linux,你可以这样做:
import array
import struct
import socket
import fcntl
SIOCGIFCONF = 0x8912 #define SIOCGIFCONF
BYTES = 4096 # Simply define the byte size
# get_iface_list function definition
# this function will return array of all 'up' interfaces
def get_iface_list():
# create the socket object to get the interface list
sck = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
# prepare the struct variable
names = array.array('B', '\0' * BYTES)
# the trick is to get the list from ioctl
bytelen = struct.unpack('iL', fcntl.ioctl(sck.fileno(), SIOCGIFCONF, struct.pack('iL', BYTES, names.buffer_info()[0])))[0]
# convert it to string
namestr = names.tostring()
# return the interfaces as array
return [namestr[i:i+32].split('\0', 1)[0] for i in range(0, bytelen, 32)]
# now, use the function to get the 'up' interfaces array
ifaces = get_iface_list()
# well, what to do? print it out maybe...
for iface in ifaces:
print iface
