问题 I have a java process that make use of ServerSocket API (Java 8) and bind to the local port 12000. Process runs under a Windows service Wrapper (exe4j). I have a scheduled task that runs at 4am that stop the service and restart it after a couple of seconds. That process is installed over 400 customers locations. Everything was running smooth until about last friday. A few processes failed to restart properly at 4am. On 2 servers I was able to connect and verify, the restart failed with both a

How find PID by port in windows and kill found tasks using java

江枫思渺然 提交于 2019-12-11 03:59:51
问题 I need kill process in java code by process port. I can do it manually in cmd like: C:\>netstat -a -n -o | findstr :6543 TCP 0.0.0.0:6543 0.0.0.0:0 LISTENING 1145 TCP [::]:6543 [::]:0 LISTENING 1145 C:\>taskkill /F /PID 1145 In java I could execute cmd command like: ProcessBuilder builder = new ProcessBuilder("cmd.exe", "/c", "netstat -a -n -o | findstr :6543"); But I don't know how get PID as output of netstat and transfer it to the "taskkill" command. Could anyone suggest me? 回答1: You can

Netstat -ban (or -oan) equivalent in .NET

一个人想着一个人 提交于 2019-12-10 17:13:29
问题 I'd like to know if a particular process is using a given port, i.e. netstat -ban . I came across using IPGlobalProperties to get the list of active connections, but this doesn't seem to include process information. It would be nice if there exists some class in C# that lets me do this programmatically. Ideally, I wouldn't have to pipe the cmd shell Process output. 回答1: Please see this question... Which PID listens on a given port in c# Basically you PInvoke GetExtendedTcpTable() 来源: https:/

Port Stuck in Time_Wait

问题 I have a TCP Tunnel in C#. I need to open and close the tunnel which is my app between a server and a client. I'm using this to close the data connection to test out another app. I have to use particular ports. On the second, third, nth connection depending on how long I wait to reconnect, I receive a 10048 error code - "Address already in use" when binding my socket. When closing the sockets, I do perform ShutDown.Both and Close in hopes of clearing out the ports, but when I do a netstat in

netstat命令总结 https://www.cnblogs.com/chenqionghe/p/10654109.html nestat介绍 netstat是一款命令行工具,可用于列出系统上所有的网络套接字连接情况,包括 tcp, udp 以及 unix 套接字,另外它还能列出处于监听状态(即等待接入请求)的套接字。 使用参数说明 与路由有关的参数 -r : 列出路由表,功能如route命令 -n : 不使用主机名与服务名称,使用ip与port number,如同route -n 与网络接口有关参数 -a : 列出所有的连接状态,包括tcp/udp/unix socket等 -t : 仅列出tcp数据包的连接 -u : 仅列出udp数据包的连接 -l : 仅列出已在listen(监听)的服务的网络状态 -p : 列出pid进程号与program文件名 -i : 打印网络接口 -g : 显示IPv4和IPv6的多播组信 -c : 可以设置几秒后自动更新一次,例如-c 5为每5s更新一次网络状态 -s : 显示网络统计数据 -e : 显示更多的信息(如用户ID、网卡IP等) 使用示例 1.列出当前路由表的状态,以ip及port number显示: netstat -rn 2.列出当前所有的网络连接,以ip与port number显示 netstat -an 3

Why is my socket's open port not listed by netstat?

问题 If you run this example, you'll see the port is never listed by netstat . Why?
