mac-address

问题 I'm trying to spoof the MAC address of the computer that executes my program. Right now I'm getting the current MAC address of the machine using the 'getmac' command via cmd, then I want to change it via the 'RegistryKey' class(windows.system32). The issue is that I don't know the string to pass to the OpenSubKey method. For example this is the method to read the current MAC with registry key reading: private string readMAC() { RegistryKey rkey; string MAC; rkey = Registry.LocalMachine

问题 I'm trying to understand what sort of structural changes happens to the IP packet during the Hop.

问题 I am building an app where I do not want a loginsystem. I still want to be able to know what user is sending information to my online database. As far as I know, the UDID is not allowed to upload to any servers, so that is out of the question. Can I use the iphones mac address for this? If it is dynamic, it will change from time to time, and I won't be able to track it. 回答1: We use the MAC address as a unique identifier now the UDID has been deprecated. MAC addresses are hardware based and

问题 i have a client server application in MFC using UDP where the server displays the IP address of connected clients in a listbox. If i run the client and server on the same computer the program displays the MAC address but if i try to run the client on a different computer the program crashes . Here are the 3 functions. I have an event handler for the listbox that displays the MAC address in a second listbox when an IP address is selected. PrintMACFromIP is the code for getting the MAC address

问题 I want to accesss the mac address of the computer using c#. I have used the following code to access mac address but there is some issue in this code. Code 1 foreach( NetworkInterface nic in NetworkInterface.GetAllNetworkInterfaces() ) { if( nic.OperationalStatus == OperationalStatus.Up ) { Console.WriteLine( nic.GetPhysicalAddress().ToString() ); checkMAC = nic.GetPhysicalAddress().ToString(); break; } } Code 2 ManagementClass mc = new ManagementClass("Win32_NetworkAdapterConfiguration");

问题 How may I use C or C++ PROGRAM (no command line) to get the MAC addresses (I'll take the IP addresses too if they are "free") on my (small) local network. It's an embedded Busybox Linux so I need a minimalist answer that hopefully doesn't require porting some library. I don't have libnet or libpcap. The arp cache seems to never contain anything but the MAC if the DHCP host. 回答1: Full source here. Open /proc/net/arp , then read each line like this: char line[500]; // Read with fgets(). char ip

问题 I have written some C# code that I am using to run an file "snmpwalker.exe" that is returning details about so cisco switches when I pass in the correct community string ip address and vlan information with an OID. I have been able to get enough information to be able to map the MAC addresses to the switch's ports but I want to also find out the ip addresses. Does anyone know what the OID for snmp would be to get back a list with mac addresses and ip addresses on a cisco switch? I haven't

问题 So I am TRYING to make a bash file that rotates my MAC address every 10 minutes with a random hexadecimal number assigned each time. I would like to have a variable called random_hexa assigned to the result of this command: openssl rand -hex 6 | sed 's/\(..\)/\1:/g; s/.$//' . I would then take the variable and use it later on in the script. Any Idea how to take the result of the openssl command and assign it to a variable for later use? Thanks! 回答1: Store the variable like so: myVar=$(openssl
