问题 I'm using Android with Api level 8 and I want to get the Address of my Ethernet interface (eth0). On API level 8, the NetworkInterface class don't have the function getHardwareAddress(). The WifiManager also does not work since this is not an Wireless interface. Thanks in advance! 回答1: Assuming your ethernet interface is eth0, try opening and reading the file /sys/class/net/eth0/address . 回答2: This is my solution based on the Joel F answer. Hope it helps someone! /* * Load file content to

问题 I've got a school demo tomorrow and because I don't have a laptop I need to use remote desktop to access a DB on my home machine for the demo. I can access my desktop from another machine on my ethernet by using the IP address I get from ipconfig, but here's the problem: The address of my home machine from ipconfig is of the form 192.168.1.XXX where my subnet mask is 256.256.256.0 I'm worried that once I'm on a machine outside of my ethernet the 192.168.1.XXX address will no longer work

问题 I'm performing network monitoring with a software developed by my company. For each machine, I have the mac address of the card used to connect to the network. I'm looking for a way to know, from the MAC address (for example), if the card is an Ethernet card or a wireless card. I can use nmap and openvas sensors results in my analysis. The final goal is to get a hint to know if the machine is a workstation or a laptop. I'm programming in python, but any other solution is welcome. Thanks 回答1:

问题 I am trying to do something very simple that does not work: With my C# application I simply want to listen for UDP packages on a specific port. With Wireshark I can see very well that the packages that I desire are received perfectly fine (CRC and everything ok). However, none of the codes I found on internet work. For example this one failes as well: private void ReceiveAsync() { UdpClient Client = new UdpClient(new IPEndPoint(IPAddress.Any, 51200)); try { Client.BeginReceive(new

问题 I've to write an application on Linux that has the requirement to talk with a device with custom Ethernet type. There are many solutions even in SO how to write such an application. A drawback is that for this root access is needed (AFAIK). Releasing the root rights afterwards could be an option, but it raises the problem that the program is developed in an IDE, which I don't like to run as root. In my special case the main application is written in Python which would mean to give root access

问题 I'm using an ethernet shield for Arduino to connect it to a socket server (different computer) so that I can receive messages from it to activate some routine. Here is my code: #include <Ethernet.h> #include <SPI.h> byte mac[] = { 0x90, 0xA2, 0xDA, 0x0F, 0x5A, 0x21 }; byte ip[] = { 192,168,1,11 }; //ip shield byte server[] = { 192,168,1,7 }; // ip server EthernetClient client; String readString; int ledPins[] = {19, 17, 2,3, 5, 6, 7, 8, 9}; // leds pins int pinCount = 8;// number of leds int
