内网可以，但外网无法ping通 在配置完网络文件以后，我发现只能ping通内网，但是却无法连上外网 为了解决这个问题，我找到了三种方法 方法一 修改vim /etc/reslov.conf 但是这种方法每次重启虚拟机nameserver就没有了，还需要重新填 方法二 修改eth0里面的文件 vim /etc/sysconfig/network-scripts/ifcfg-eth0 但这个修改过以后要重启网络 service network restart 方法三 如下图所示操作 最后输入 ping www.baidu.com就OK了 来源： CSDN 作者： 3.14159265358979 链接： https://blog.csdn.net/weixin_44988131/article/details/103464884

Get the IP of a server through powershell when it doesnt respond to a ping

由 夙愿已清 提交于 2019-12-11 02:43:18
问题 Due to firewall constraints, the servers I deal with do not reply to a ping, but do give their IP address for eg, if I do : ping myhost.com I get Pinging myhost.com [192.1.1.1] with 32 bytes of data: Request Timed Out. How can I just get the IP of the server from powershell? I know it can be done various ways if a server responds to a ping (Test-Connection or Ping-Host) , but I cant figure it when it ignores ping requests 回答1: You can use the System.Net.Dns.GetHostAddresses method.

Applescript to ping test each client prior to ssh connection

由 自古美人都是妖i 提交于 2019-12-11 01:26:45
问题 I'm trying to make an Applescript that connects to a list local ssh machines, with each connection opening in a new terminal window. Prior to attempting the ssh connection, I'd like to ping the client to see if it's available: if it is, run the ssh command, if not then iterates to the next client. When I run the script it seems to work for the first connection but then gives me --> error number -10004 for the remaining clients (and hangs the debugger). Any feedback would be greatly

问题 Im currently doing research towards my final year BSc project. The final product will include indoor location tracking functionality. The traditional, or most utilised method seems to be RSSI triangulation, but I am keen to attempt to improve the accuracy of the PING method as I think this would be better suited to locations that may suffer from signal attenuation (the locations I am intending to use the device may have a moderate ammount of radio interference). I was wondering if it was

问题 Looking for a better way to do this rather than the "by-hand" method I'm used to, because it's a process I have to go through fairly regularly. I have a range of IPs to ping, from 10.0.1.15 to 10.0.50.15 . The third octet refers to a physical location and the last octet refers to a device at that location. I need to see which locations DO NOT have that device hooked up to the network. My current solution is: FOR /L %i IN (1,1,50) DO ping -n 1 10.0.%i.15 >> C:\path\to\output\file.txt This

Is there a way to “ping” an IPhone to see if it's turned on?

问题 I am currently working for a tech support company. I want to set up a script for our phone system that will check and see if a person's IPhone is powered on, and if not move to the next person in the escalation list. Or possibly try alternative numbers that we don't want to give out to the customers. (Personal cells, and in a real emergency there home number.) I tried getting the IP address of my phone from what's my IP .com but I can't seem to ping that number. :( 回答1: In most cases (all?)

问题 I am developing an universal windows app for Windows 10 IoT using VB.NET. I am checking for two things - first is, if there is any network at all. I am using Imports System.Net NetworkInformation.NetworkInterface.GetIsNetworkAvailable for this. But what this does not tell me is if I really do have internet access, it only indicates if I am connected to a network. Is there any way to ping an address (like 8.8.8.8)? I cannot find a solution. The device will only be used for private purposes,
