Wrong DNS Settings, php_network_getaddresses: getaddrinfo failed Name or service not known, nslookup

问题 The problem originally looked like this: Warning: file_get_contents() [function.file-get-contents]: php_network_getaddresses: getaddrinfo failed: Name or service not known in /home/ / /ppk_hotweb.class.php on line 58 I used cURL as well, it just returned null, that's it.. Both (file & cURL) were enabled. Tried file_get_contents('google.com') and it worked! Why doesn't file_get_contents('domain.com.au') work then? So I started reading relevant stackoverflow posts and people say that this is a

问题 Issue with command output: I am attempting to have a continuous ping report back to a text file. Started with: ping 127.0.0.1 -t >> C:Textping.txt Works great I also want to have timestamps listed before each ping So Wrote: Dim str Do While Not WScript.StdIn.AtEndOfStream str = WScript.StdIn.ReadLine WScript.StdErr.WriteLine now & " - " & str Loop Saved it as timestampLog.vbs on my desktop and dropped a copy into my system 32 folder. Put all of this into a batch file: ping 127.0.0.1 -t |

问题 I need to create application which will be pinging multiple addresses in loop. I read a lot of examples here at stackoverflow and finally got working code: public void Check(List<string> addresses) { List<Task<PingReply>> pingTasks = new List<Task<PingReply>>(); foreach (string address in addresses) { pingTasks.Add(PingAsync(address)); } Task.Factory.ContinueWhenAll(pingTasks.ToArray(), _ => { }).ContinueWith(t => { StringBuilder pingResult = new StringBuilder(); foreach (var pingTask in

.NET Ping() giving false timeouts?

问题 I have a script that is looping through and sending a ping to a host every second. The purpose of which is to test wireless performance on my home network. The issue is, I seem to be getting timeouts from my script, while a standard "ping -t" on either client (pingER and pingEE) have no such timeouts. In fact, not once in the last 30 minutes has either timed out, while my script has received timeout replies every few minutes. My essential script is below. In all cases, when it does happen, my

What does “2>&1” in a Windows Command Do?

由 ぐ巨炮叔叔 提交于 2019-12-22 06:31:10
问题 Doing some maintenance on a script, I found this line: ping -n 40 127.0.0.1 > NUL 2>&1 I know from this question that everything up to the NUL causes the script to sleep for 39 seconds. But I don't know what the rest of the command does. What does the 2>&1 do? 回答1: Decomposing the line ping -n 40 127.0.0.1 Send 40 ping packets to local host. If there is not any problem the default behaviour is to wait 1 second between packets, so it generates a 39 second delay >nul or 1>nul Redirects anything

VMware安装CentOS后网络设置

　　在使用CentOS虚拟机后，出现了无法上网的情况，使用主机ping虚机地址可以ping通，而虚机ping不通主机，同时虚机也无法ping通其他的网址或ip，显示内容为Network is unreachable，后来经过在网上查找找到采用NAT模式的解决方法，解决问题，记录如下： 1、打开服务（services.msc），确保VMware的DHCP和NAT服务开启。 2、修改虚机的接入方式，可以在“编辑虚拟网络”中查看，如下： 打开后界面如下： 3、点击VMnet8，设置相关信息：一般采用默认配置即可，若图中1处的子网IP自己调整，相应的2、3也需要做对应的调整： 4、在虚机设置中选择NAT连接方式，，如果没有网络连接方式需要自己添加一下。 5、打开虚机看看虚机的网络设置了。命令如下 #vi /etc/sysconfig/network-scripts/ifcfg-eth0 其中部分内容如下： DEVICE=eth0 #设备名称，可根据ifcofnig命令查看到。 BOOTPROTO=dhcp #连接方式，dhcp会自动分配地址，此时不需要在下面设置ip和网关 HWADDR=00:0C:29:AD:66:9F #硬件地址，可根据ifcofnig命令查看到。 ONBOOT=yes #yes表示启动就执行该配置，需要改为yes 网上会有些方法需要在这里添加ip地址，子网掩码

【教程】虚拟机安装CentOS 7 ping不通百度/并且使用Xshell 连接

最近需要在电脑虚拟机上安装CentOS 7 ，之前对虚拟机并不熟悉，捅咕了两天时间，如果终于安装成功。 之前遇到的坑：安装完CentOS 7 之后一直ping 不通www.baidu.com 网上查询多个资料，最后参考： https://jingyan.baidu.com/article/363872ec796dfc6e4ba16f09.html 这篇文章安装成功。 说到底就是dns地址配置的问题，现在把dns 和ip设置的重要步骤记录一下，以防以后忘记： 1：首先下载最新版 CentOS镜像： http://isoredirect.centos.org/centos/7/isos/x86_64/CentOS-7-x86_64-DVD-1810.iso 2：之后虚拟机VM安装CentOS 7 由于步骤过长我就不截图了，其中过程中重要的就是配置虚拟机IP地址 3:安装过程中ip配置很重要，博主查下本地的ip地址 cmd->ipconfig /all 其中ip地址要和本地的在一个网段上 4：安装完之后编辑 vi /etc/sysconfig/network-scripts/ifcfg-ens33 文件。图中框出来的很重要 这里的ip是自己设置的，前三个地址一致，最后一个要同一网段，不同ip， 网关和子网掩码要和当前wifi连接配置的一致 参考设置地址： https://blog
