This block of code is what everyone seems to use: try { InetAddress address = InetAddress.getByName("172.16.2.0"); // Try to reach the specified address within the timeout // periode. If during this periode the address cannot be // reach then the method returns false. boolean reachable = address.isReachable(10000); System.out.println("Is host reachable? " + reachable); } catch (Exception e) { e.printStackTrace(); } My

System.Net.NetworkInformation.Ping crashing

阅读更多关于 System.Net.NetworkInformation.Ping crashing

问题 So, I have a site with over 600 devices. I'm trying to ping them all one by one using the standard .NET ping class. For some reason, this thread is crashing - it just stops responding after a few days. All it does is ping devices on the network. We're using Microsoft Windows Server 2008 R2. Is there any problems with the .NET ping class? I also seem to be experiencing memory leaks which I'm guessing is due to the pinging. Should I just write a win32 ping dll to do the job for me or am I doing

IPv4 ping命令给一台 Linux 主机分配了一个 IPv4 的 IP地址，如何使用 ping命令确定该 IP地址能否 ping 通呢？ 1、查看主机的 IPv4 的 IP地址信息命令如下： ip addr | grep net 通过命令可以看到，该主机的 IPv6 的IP地址为： 192.168.254.117 2、使用 ping 命令进行 ping IPv4 的 IP 命令如下： ping 192.168.254.117 执行命令后，可以看到该 IPv4 的 IP地址可以 ping通。 PS：强烈推荐一款个人常用的 SSH客户端神器 MobaXterm ，比 Xshell 更好用，请参考如下博文： https://www.cnblogs.com/miracle-luna/p/12008869.html 如何 ping IPv6 的 IP地址，请参考如下博文： https://www.cnblogs.com/miracle-luna/p/12017740.html 希望能帮到大家，谢谢！来源： https://www.cnblogs.com/miracle-luna/p/12017857.html

C# perform a TNSPing programmatically

问题 Is it possible to perform a TNSPing on an Oracle Database programmatically? I'm aware I could probably call the TNSPing program and parse any output generated but I'm looking for a more robust method of handling the database TNS Ping. Having seen the Ping class on MSDN, I tried to use the example code found, but I think I would need some way to resolve the TNS name into an actual IP address for this method to work. Is this possible? 回答1: This Forum seems to suggest that attempting to use

问题 I am in the process of writing a simple program that extracts computer names from MySQL Database then stores those names into a String array list (this part works fine).

Here is the code for that class: public class Ping { public void pingHost(String hostName) { try { InetAddress inet = InetAddress.getByName(hostName); boolean status = inet.isReachable(5000); if

问题 I want to make a little tk app that continuous ping an ip and only show the MS, like, "10ms" how could I do? 回答1: If you want to use Windows ping , you'll have to parse the output from the command line. This is very specific, but should work: import os while(1): ping = os.popen('ping www.google.com -n 1') result = ping.readlines() msLine = result[-1].strip() print msLine.splot(' = ')[-1] 回答2: To continuously ping an IP os.system("ping -t 192.168.1.1") 来源： https://stackoverflow.com/questions
