How to “unbind” a socket programmatically?

牧云@^-^@ 提交于 2019-12-04 13:18:12
1) The socket doesn't seem to unbind from the LocalEndPoint until the process ends. 2) I have tried the solutions from the other question, and also tried waiting a minute - to no avail. 3) At the moment I have tried the below to get rid of the socket and its connections: public static void killUser(User victim) { LingerOption lo = new LingerOption(false, 0); victim.connectedSocket.SetSocketOption(SocketOptionLevel.Socket,SocketOptionName.Linger, lo); victim.connectedSocket.Shutdown(SocketShutdown.Both); victim.connectedSocket.Disconnect(true); victim.connectedSocket.Close(); clients.RemoveAt

Paramiko SSH Tunnel Shutdown Issue

淺唱寂寞╮ 提交于 2019-12-04 13:17:07
问题 I'm working on a python script to query a few remote databases over an established ssh tunnel every so often. I'm fairly familiar with the paramiko library, so that was my choice of route. I'd prefer to keep this in complete python so I can use paramiko to deal with key issues, as well as uses python to start, control, and shutdown the ssh tunnels. There have been a few related questions around here about this topic, but most of them seemed incomplete in answers. My solution below is a hacked

Prevent windows shutdown from python

I want to prevent windows (xp and 7) from shutting down. For that it seems I have to intercept the WM_QUERYENDSESSION message and return False. Ok I have to correct my statement, this program works fine under Windows 7 but on Windows 7 embedded Standard Service Pack 1 it does not prevent the shutdown!? import ctypes from ctypes import c_long, c_int, c_wchar_p import time import win32api import win32con import win32gui import win32process oldWndProc = None def wndproc(hWnd, msg, wParam, lParam): print("wndproc received message: %s" % msg) if (msg == win32con.WM_QUERYENDSESSION): print("wndproc

Terminate Amazon EC2 instance using shutdown

非 Y 不嫁゛ 提交于 2019-12-04 11:27:04
I can terminate Amazon EC2 instances using the API command ec2-terminate-instances but I'm trying to find out how to do this while logged onto the EC2 instances themselves. I've tried shutdown -h now but this only "stops" the instance, without fully terminating it. Is there any way to do this? There is an option that you can set at instance creation that will allow the instance to terminate on shutdown. If you're using the ec2 command line tools, add the option: --instance-initiated-shutdown-behavior terminate After creating an instance with that option, issuing the shutdown -h now command

spring cloud踩坑指南

版本信息: spring cloud 版本Greenwich.SR2 spring boot 版本2.1.8.RELEASE gateway报错 DefaultDataBuffer cannot be cast to org.springframework.core.io.buffer.NettyDataBuffer 解决方式: springcloud的gateway使用的是webflux,默认使用netty,所以从依赖中排除 tomcat相关的依赖 ,就可以了。 我的问题: 排除了依赖还是报错。后来发现使用了 tomcat-embed-core 包导致的,删除再引文需要的jar包即可。 starter-openfeign starter-feign 区别( 来源 ) Feign Feign是Spring Cloud组件中的一个轻量级RESTful的HTTP服务客户端 Feign内置了Ribbon,用来做客户端负载均衡,去调用服务注册中心的服务。 Feign的使用方式是:使用Feign的注解定义接口,调用这个接口,就可以调用服务注册中心的服务 Feign本身不支持Spring MVC的注解,它有一套自己的注解 OpenFeign OpenFeign是Spring Cloud 在Feign的基础上支持了Spring MVC的注解,如@RequesMapping等等。

Android root poweroff

On my android app for root user, I perform a shutdown with su reboot -p It works ok, but I noticed that the phone is shutdown almost instantly (as opposed from showing the shutdown animation, and probably doing other stuff). Is this the correct way to shutdown an android phone programmatically? Are there some critical code that requires to be executed before shutdown? Yury In the Android source code, you can find the following: /** * Low-level function turn the device off immediately, without trying * to be clean. Most people should use * {@link android.internal.app.ShutdownThread} for a clean

Is there any API function for shutting down Windows while installing any pending updates?

烂漫一生 提交于 2019-12-04 02:47:20
I know the ExitWindowsEx() API function which simply shuts down Windows. But as far as I know, you cannot make Windows install any pending updates with it. Is there any API support for installing any pending updates (in that standard blue screen which says " n of m updates have installed - Please don't turn off or unplug your PC, Windows will shut down itself ") then shutting down Windows (equivalent to clicking the "Install updates and shutdown" menu option of the Windows user interface)? (OS Version: Windows XP and higher.) The best you can do is call InitiateShutdown and include the

What happens if System.exit is called from a shutdown hook?

a 夏天 提交于 2019-12-04 01:43:54
I have a rather complicated shutdown in Java - there's a lot of clean up work to do. In particular I'm trying to figure out how to error handle from a shutdown hook thread. My code includes this currently: try { return shutdownPromise = doShutdown(); } catch (Throwable exc) { logger.error("An exception was thrown while shutting down the application.", exc); System.exit(1); return null; } When I originally wrote this I essentially thought, an error in shutdown should just go straight to exit . But exit is not so low level; it calls the shutdown hooks. So I thought - What does calling exit from
