问题 This question already has answers here : Not able to start Genymotion device (24 answers) Closed 4 years ago . This question might seem a duplicate of this question but it's not because i've tried almost everything in this world to get a device run in genymotion. Everytime i try to start a device i get the error: after some minutes looking for the log file i could found it and the last line (where it get stuck) says this: Mar 27 04:01:31 [Genymotion Player] [Error] Can't detect device IP

实操 ：华为DHCP中继服务配置

由 大憨熊 提交于 2019-12-11 20:59:05
前言： 该实验是华为模拟器eNSP模拟器、dhcp中继实验 #DHCP中继的应用场景： 通常在DHCP分配网段过多的情况下，网关路由器上配置DHCP服务，压力过大， 一般我们用第二路由器，或则第二台DHCP服务器来分担业务 dhcp 中继 这里设置一台专用的DHCP服务器为pc机配置IP地址 LSW1 <Huawei>system-view Enter system view, return user view with Ctrl+Z. [Huawei]sysname LSW1 [LSW1]un in en Info: Information center is disabled. [LSW1]vlan bat 10 20 Info: This operation may take a few seconds. Please wait for a moment...done. [LSW1]int e 0/0/1 [LSW1-Ethernet0/0/1]p l a [LSW1-Ethernet0/0/1]p d v 10 [LSW1-Ethernet0/0/1]un sh Info: Interface Ethernet0/0/1 is not shutdown.

eNSP——配置全局地址池的DHCP

由 放肆的年华 提交于 2019-12-11 17:05:36
原理： 拓扑图： 实验编址： 1.基本配置 2.配置全局地址池的DHCP Server 在R1上开启DHCP功能，使用ip pool命令创建一个全局地址池，名字自己定。 在全局地址池配置网段、掩码、租期、出口网关地址、DNS服务器地址。（上一个随笔有） 开启接口的DHCP功能。使用该命令配置设备指定接口采用全局地址池为客户端分配IP地址。 因为我们有两个PC机，要分配不同的IP地址，所以需要两个全局地址池。 我们可以用 display ip pool 来查看一下IP地址池的信息。 我们看一下，分配好IP了吗 因为我们对 qiyaun2 地址池没有禁用IP地址范围，所以DHCP给他分配的IP是192.168.2.253 来源： https://www.cnblogs.com/qi-yuan/p/12023608.html

eNSP——配置基于地址池的DHCP

由 久未见 提交于 2019-12-11 16:50:30
原理： 实验案例： 拓扑图： 实验编址： 1.基础配置 根据实验编址进行实验的基础配置。 2.基于接口配置DHCP Server功能 在R1上开启dhcp 功能，在接口上开启dhcp服务功能，指定从接口地址池分配地址。 3.配置基于接口的DHCP Server租期/DNS服务器地址 配置DHCP服务器接口地址池中IP地址的租用有效期，默认值是1天，超过租期后会重新分配。 配置接口地址池不参与自动分配的IP地址为192.168.1.1-192.168.1.10 分配DNS服务器地址为8.8.8.8 现在我们已经配置好了，我们去看一下可以分配的地址 在IPv4上点DHCP PC2也像PC1这么配置就可以了 来源： https://www.cnblogs.com/qi-yuan/p/12021887.html

Is there a way to use the IP address in a VagrantFile that Virtualbox assigned by DHCP?

由 元气小坏坏 提交于 2019-12-11 14:27:56
问题 I am creating a VirtualBox machine with Vagrant. In the provisioning I need to know the IP address of the box that was assigned by the VirtualBox DHCP. Is there any way to use that assigned IP address in the Vagrantfile? Vagrant.configure(2) do |config| # ... some more config config.vm.network "private_network", type: "dhcp" # ... some more config config.vm.provision "shell", inline: <<-SHELL sudo -i /vagrant/my_provisioning_script.sh <insert ip here> SHELL end 回答1: You can do an ifconfig

How to setup PXE on separate DHCP server [closed]

由 ≡放荡痞女 提交于 2019-12-11 13:01:47
问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 2 years ago . my network has a DHCP server incapable of serving PXE requests (you cannot set next-server option at all) and thist server MUST remain as DHCP server. I would like to have a PXE booting on the network, but as I said earlier, I cannot do that with this current DHCP server. Is it possible to for example setup

问题 Closed . This question needs to be more focused. It is not currently accepting answers. Want to improve this question? Update the question so it focuses on one problem only by editing this post. Closed 5 years ago . I want to get the list of all IP addresses (i.e devices) present in a local area network. I don't want to use nmap, other networking tools. And also I don't want to ping each Ip address in a sub-net range and find live IP addresses? Is there any way by using C, C++? 回答1: There is

sendto function setting “network is unreachable” errno

由 你说的曾经没有我的故事 提交于 2019-12-11 08:13:43
问题 I'll apologise for any lack of clarity, and I'll do my best to update with any missed info, but I'm struggling to understand what I need to do to figure out why the network is unreachable. I'm getting the output "sendto failed Network is unreachable" from the function int send_dhcp_packet(void * buffer, int buffer_size, int sock, struct sockaddr_in* dest) { int result; result = sendto(sock, (char*) buffer, buffer_size, 0, (struct sockaddr*)dest, sizeof(*dest)); if(result < 0) { printf("sendto

Programmatically Create DHCP Reservation in C#

由 扶醉桌前 提交于 2019-12-10 21:05:01
问题 I have been assigned the task of creating an application that takes in a MAC address and creates a DHCP reservation for that MAC address. Is there any API built into .NET to easily accomplish this? 回答1: When I was writing apps for infrastructure there was a COM library called Dhcpobjs.dll in the Windows 2000 Resource Kit. This could be dynamically loaded by a VBScript using IDispatch like so: Set DhcpMgr = CreateObject("Dhcp.Manager") Set DhcpServer = DhcpMgr.Servers.Connect("192.130.1.5") I
