[英]bind/connect to network interface card using python
我正在尝试连接/绑定到特定的网络接口卡(NIC)或无线网络接口。 例如,当我创建套接字时,我想使用网络名称(例如'wlan0'或'eth0')进行连接,而不是使用IP地址。 在JAVA中,我可以使用以下代码轻松完成此操作:
//Initializing command socket
//String networkCard = "wlan0"; //or could be "eth0", etc.
NetworkInterface nif = NetworkInterface.getByName(networkCard);
Enumeration<InetAddress> nifAddresses = nif.getInetAddresses();
// IP address of robot connected to NIC
SocketAddress sockaddr = new InetSocketAddress("192.168.1.100", 80);
sock = new Socket();
// bind to the specific NIC card which is connected to a specific robot
sock.bind(new InetSocketAddress(nifAddresses.nextElement(), 0));
sock.connect(sockaddr,10000);
我想把它翻译成Python,但我很难过。 有关如何做到这一点的任何建议?
我正在使用sockopt和AF_CAN,但没有任何工作。
非常感谢你!!!
实际上答案很简单。 它类似于Idx在之前的回答中所做的:
def findConnectedRobot():
'''
Finds which robots are connected to the computer and returns the
addresses of the NIC they are connected to
'''
robot_address = [] # stores NIC address
import netifaces
# get the list of availble NIC's
for card in netifaces.interfaces():
try:
# get all NIC addresses
temp = netifaces.ifaddresses(\
card)[netifaces.AF_INET][0]['addr']
temp2 = temp.split('.')
# see if address matches common address given to NIC when
# NIC is connected to a robot
if temp2[0] == '192' and int(temp2[3]) < 30:
print('appending address: ' + temp)
robot_address.append(temp)
except BaseException:
pass
return robot_address
在我得到“机器人地址”后,我可以像普通插座一样绑定/连接它们。
谢谢您的帮助!
你需要libnl及其python绑定:
#!/usr/bin/env python
import netlink.core as netlink
import netlink.route.link as link
import netlink.route.address as Address
sock = netlink.Socket()
sock.connect(netlink.NETLINK_ROUTE)
cache = link.LinkCache()
cache.refill(sock)
intf = cache['wlan0']
addr_cache = Address.AddressCache()
addr_cache.refill()
for addr in addr_cache:
if addr.ifindex == intf.ifindex:
print addr
