Mac adresse ip herausfinden linux

Your Answer

This option tells Nmap not to do a port scan after host discovery, and only print out the available hosts that responded to the scan. This is by default one step more intrusive than the list scan, and can often be used for the same purposes. It allows light reconnaissance of a target network without attracting much attention.

Knowing how many hosts are up is more valuable to attackers than the list provided by list scan of every single IP and host name.

Nmap sends an ICMP type 8 echo request packet to the target IP addresses, expecting a type 0 echo reply in return from available hosts.. Unfortunately for network explorers, many hosts and firewalls now block these packets, rather than responding as required by RFC [2]. For this reason, ICMP-only scans are rarely reliable enough against unknown targets over the Internet.

But for system administrators monitoring an internal network, they can be a practical and efficient approach. Use the -PE option to enable this echo request behavior.

I am trying to learn about this layer of networking and the tools to monitor it. You can use arp command: The MAC layer headers of input packets are stripped out by the router, and new ones added to the outgoing packet.

From the manual: I don't know of an existing Python module to get this information. You could use ctypes to call the ioctl directly. Thank you for your interest in this question.

You can import the mac finding function into your own code easily: Armin Ronacher Armin Ronacher I just tried this on a Windows box and it works great Just a word of warning if you want to use this code. Just a warning: If you look at the getnode documentation it says that it will return a random long if it fails to detect the mac: The pure python solution for this problem under Linux to get the MAC for a specific local interface, originally posted as a comment by vishnubob and improved by on Ben Mackey in this activestate recipe!

Peter Turner 4, 8 54 The first time this runs, it may launch a separate program, which could be quite slow. If all attempts to obtain the hardware address fail, we choose a random bit number with its eighth bit set to 1 as recommended in RFC Not that the value of the 8th is 1 precisely because it cannot be used by a network card. Just checking this bit is enough to detect whether the address is faked or not. The check is just done with: Sometimes we have more than one net interface. A simple method to find out the mac address of a specific interface, is: Julio Schurt Julio Schurt 1 6 Not super useful for OS X or Windows.
