affirm virtual card

I recently tested the voice function of Lync. The environment has been set up in a virtual machine, but the sound card is not supported in Hyper-V. the test has not been successful yet. After some attempts, the test is successful. The details are as follows: 1. The real machine is Win7 Enterprise Edition, and the virtual machine is also Win7 Enterprise Edition. (

source host is manually configured IP).Any execution of the following commands is useless anyway:/etc/init.d/network restartIfup eth0Workaround:1. Edit the eth0 configuration file: Vi/etc/sysconfig/network-scripts/ifcfg-eth0, delete the hwaddr address the line and UUID lines are as follows:hwaddr=00:0c:29:08:28:9fUuid=cee39dbb-6a10-4425-9daf-768b6e79a9c9Tip: Of course you can also modify the actual hwaddr and UUID without deleting it. See/etc/udev/rules.d/70-persistent-net.rulesEth0 Nic File mo

I installed the VMware virtual machine, but the installation of Mac system, the process is more troublesome, so I have installed a copy of the classmate Mac virtual machine files, copy and then add to the virtual machine inside, the boot time has been open in the boot loading interface, The solution to this problem is the same as the one in my last blog post, whi

1, run the command prompt as the administrator. Start → run, enter cmd. 2. At the command prompt, enter the command: netsh wlan set hostednetwork mode=allow ssid= The name of the wireless network you want key= the password you want to set. 3, then open the Network Sharing Center-Change adapter settings, you will find one more Microsoft Virtual WLAN Miniport Adapter, this is the wireless network adapter that we just invented. 4.

In Linux, we can use the loopback interface to simulate ROUTING decisions in two stages. The first stage is to go through the PRE/post routing process to complete NAT implementation, the second stage completes pure route forwarding. However, you need to hook the child on Netfilter to cancel the route entry associated with skb and cancel the conntrack information associated with skb, because in the pure routing process in the second stage, I don't want any more conntrack-based actions. Therefore,

Environment: VMware System: centos-7.0-1406-x86_64-everythingFirst, configure the network card vim/etc/sysconfig/network-scripts/ifcfg-eno16777736CENTOS7 network card name with the previous CENTOS6 name has a relatively large change, the original rules of the ETH0,ETH1 name Wood has!!It looks awkward, so it's good to use table completion when editing the NIC 2. Modify the configurationType=eth

Under the cmd command line, enter the Platform-tools directory. 1. Create SDcard mksdcard-l Mycard 256M E:\android\myCards\mysdcard.img This creates a virtual image of an SD card in this directory.Where the-l command-line parameter represents the volume label of the virtual disk. 256M is the size of the virtual sdcard

After cloning, the VMware virtual machine discovers that the original eth0 of the cloned host will be gone, instead there will be a new Mac Nic Eth1. This article solves how to reasonably change the NIC to eth0. Ifconfig eth1 determine the MAC address of the new network card.Nmcli con determine the UUID of the new NIC 2Vim/etc/udev/rules.d/70-persistent-net.rulesDelete the relevant information of the original eth0 and change the name of Eth1 to

Version: Centos-6.5-i386-minimal virtual machine: after installing VMware 11.1.2, the NIC information is not visible, as follows: We edit the configuration information for the NIC Etho: the onboot option Value to Yes: save to exit and restart the Network service: Review the networking configuration again: complete. Note that if it fails, the configuration options for the virtual machine network adapter are

When learning Linux, it is often necessary to clone multiple virtual machines to build an intranet environment. However, cloning the generated virtual machine Nic Mac error, but not the normal network.After a search, finally found a solution:1.ifconfig-a # Note the MAC address 00:0c:29:7b:93:9e650) this.width=650; "src=" http://s3.51cto.com/wyfs02/M02/6E/97/wKiom1WARViD-c_FAADn2jpFzIc455.jpg "title=" 1.png

In some special cases, we need a "virtual NIC" in the Windows system to achieve certain working environments, Windows 8 is created in a way that is different from other systems, and this article uses pictures to demonstrate how the "virtual network card" is created. First of all, under the traditional desktop, the mouse to move to the lower left corner of the sc

processing(11) Control IOCTL of network equipmentThe main function of Linux network device is the initialization of network equipment, the configuration of network equipment, and the sending and receiving of data packets.The following code is a sample of network-driven virtual hardware2. Code#undef pdebug/* undef it, just in case */#ifdef snull_debug# ifdef __kernel__/* This one if debugging I s on, and kernel space */# define PDEBUG (FMT, args ...)

1, enter the Linux, input Setup command: Network Configuration→device configuration→eth0 (two card, temporarily with the first) (configuration temporarily select the dhcp→ configuration is complete, click "OK" → "Save" → "Savequit" → "Quti".#该配置实质是修改网卡的配置文件 content of/etc/sysconfig/network-scripts/ifcfg-eth02. Command: Ifup eht0#启用eth0, let eth0 get the IP address.3. Command: Ifconfig#查看获取到的ip, you can also directly correspond to the NIC name: Ifconfi

The vmware Virtual Network Card in win7 shows that the solution to VMware Network Adapter VMnet1 and VMnet8 is identified by the firewall as [unrecognized Network-public Network], which is blocked and cannot use port ing, the VM port 80 cannot be passed in, and data packets can only be sent out. The public network cannot be changed to a home or work network.Solution:1. Go to the registry [HKEY_LOCAL_MACHINE
