connectivity

问题 I'm making a simple script that pings an address and save the results in a txt file. The purpose is solely to make it convenient for the lay user that don't know how to: open the "run" box; open cmd; ping an address; copy results; past to a txt file. So far, I have made this .bat file, but I wanted it on vbs for more functionalities and better visual. .BAT APPROACH @ECHO OFF :LOOPSTART time /T >> PingTest.txt ping 1.1.1.1 -n 100 >> %userprofile%\Desktop\PingTest.txt exit GOTO LOOPSTART .VBS

问题 In an Android app, I'm trying to test that the user has a working Internet connection. If you are interested, there is some background in a previous question Detecting limited network connectivity in Android? The code is basically like: try { HttpParams myParams = new BasicHttpParams(); HttpConnectionParams.setConnectionTimeout(myParams, 10000); HttpConnectionParams.setSoTimeout(myParams, 10000); httpClient = new DefaultHttpClient(myParams); request = new HttpHead(url); response = httpClient

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 So, I have this method that let's me know if the user has an active internet connection. It works well. However, leak canary has identified a memory leak associated with the connectivityManager. I am presently not closing the connectivityManager anywhere in my code at any time that I know of. I've tried to close the connectivityManager in onDestroy. Either that isn't an option or I don't know the code. Truth be told, I simply tried to get auto fill to tell me how to do it. No luck. public

问题 I am trying to install Zabbix Monitoring server on Linux Cent OS 6.x. I have installed Zabbix 2.4 version on it. I have followed the following article of Zabbix to configure it: https://www.zabbix.com/documentation/2.4/manual/installation/install_from_packages Once I reach at IPAddress/zabbix at browser settings, I have successfully passed PHP settings and configuration stage. But, when I go to next steps where I have to apply database settings, it is not working. However, I have created

The code I am using is as follows: Which I am sure

问题 Using PKCS11Interop on Safenet HSMs, I got this error "Method C_OpenSession returned 2147484548" the error, in my documentation, is CKR_SMS_ERROR: " General error from secure messaging system - probably caused by HSM failure or network failure ". This confirm the problem it happens when the connectivity is lacking. The problem is when this happens, the service isn't able to resume the communication when the connectivity is back, until I restart manually the service managing the HSM access .

问题 public boolean requestRouteToHost (int networkType, int hostAddress) This method in ConnectivityManager if used with networkType set to wifi interface always returns false. requestRouteToHost android says it was never implemented for the wifi interface. Even InetAddress.isReachable() always returns false for publicservers like google.com, java.com Is there any specific reason why they fail? The only way I could test if there was connectivity was by executing the "ping" by using runtime exec()
