nic

问题 I have a problem with a a particular licensed software that I have installed on a VM, and the software license should be tie to a public IP address on the NIC of the VM. The software checks the IP address of the server where the application is installed and verifies against the public license server of the application manufacturer, and if the IP address doesn't match, the software stops working. The software company has issue temporary license to my VM using private IP address, since I wasn't

问题 I have to differentiate between the real addresses and the VM addresses using any Windows API. I'm using GetAdaptersAddresses API to populate a list of IP addresses for the local machine. I need to extract only the "real" addresses apart from the addresses associated with the VMware network adapter and other addresses (auto-configuration and tunnel adapter addresses). I've not been able to find any API or any flag to differentiate this. Is there any way this can be done? PS : The IfType flag

问题 While working with large codebase for legacy applications, whenever I have seen a piece of code that checks whether an internet connection is active or not, I have mostly seen the uses of functions such as: InternetCheckConnection(L"http://www.google.com",FLAG_ICC_FORCE_CONNECTION,0) //or BOOL bConnected = IsNetworkAlive(&dwSens) //or InternetGetConnectedState(&dwReturnedFlag, 0) //or some other functions but there exists a very very simple way to do this where you wouldn't need to include

问题 I'm trying to come up with a solution to programmatically enable/disable the network card - I've done a ton of research and nothing seems to be a workable solution in both XP and Vista environments. What I'm talking about is if you went into the Control Panel 'Network Connections', right clicked on one and picked either enable or disable. Ideally I'd like to use a library, but if worse comes to worse I supposed I could call out to a commandline app, but that's absolute worst case. Here's what

问题 I am trying to find an active NIC, an active NIC is one where the command wil return UP for me. In my command: # cat /sys/class/net/eth0/operstate I am returned a value of UP In another command, I type: # cat /sys/class/net/eth1/operstate I get a value of DOWN Overall I have 4 eth's. I basically have to use the command to determine UP or DOWN /sys/class/net/eth[0|1|2|3]/operstate = up | down I want to be able to write a program where I will be able to return the eth[0|1|2|3] value that is UP.

问题 With the below code I am getting an error "Invalid interface LAN: specified". This code works in Win7, however, does NOT working in windows XP. I suspect it has something to do with the "!adapterName!" conflicting within XP. I utilize this script to obtain the NIC Name in case it changes in the future some how and would like to keep this scheme. Any ideas how I can continue with such script in an XP environment? :: Set primary and alternate DNS for IPv4 @ECHO OFF for /f "tokens=* delims=0" %

问题 How can I programmatically check whether my machine has internet access or not using C/C++, is it just a matter of pinging an IP? How does NIC do it ? I mean something like: I am using Windows 7. 回答1: If you work on Windows, just try this #include <iostream> #include <windows.h> #include <wininet.h> using namespace std; int main(){ if(InternetCheckConnection(L"http://www.google.com",FLAG_ICC_FORCE_CONNECTION,0)) { cout << "connected to internet"; } return 0; } 回答2: There is nothing of that
