When you do the experiment, you may need more than one virtual host, if you have to install from scratch is certainly unreasonable. There are two ways to do this: the first is to copy a virtual host directly into the folder and then import it into VMware.650) this.width=650; "Src=" Http://s2.51cto.com/wyfs02/M00/84/53/wKiom1eNgtbzFlrUAAAlyeF2czk359.png-wh_500x0-wm_3 -wmp_4-s_1982224013.png "title=" () 3@w]7nwjvgdo3c]980~h0.png "alt=" Wkiom1engtbzflruaaalyef2czk359.png-wh_50 "/> Clone a virtual

Q:route Print command mean? A:metric is in decimal. It represents which route windows prioritizes when multiple routes to the same prefix appear. The metric value is about the higher the small priority value. For example, for 172.16.0.0/16 this network, if one of the routes has a metric of 40 and the other is 39, then Windows takes precedence over the metric route 39. If at some point the route is not valid (for example, a network outage), then the route with metric is 40. If the route to metr

The following settings are passed under the Host:winpro SP2 GUEST:RH9 environment. First in the setting, the virtual machine's NIC is set to Host-only. (1) Check the properties of your network card connected to the network, select the "Advanced" tab, set it to allow sharing, and set the allowed network interface to VMNET1. (2) again to look at the properties of your VMnet1, look at the TCP/IP protocol settings, you found that has been automatically

Symptom Description: After starting the local connection normal, but not the Internet, open Task Manager on the network prompts "cannot find the active network card." Solution: On the boot, press F8 (some computer is F2) into Safe mode, right click on "My Computer"--> "Properties"--> "Hardware"--> "Device Manager", expand the "network adapter" item, uninstall the NIC, then restart the computer, the boot will automatically load the driver, If you cann

Sometimes it may need to be updated, sometimes to reinstall, small set

Method One, 1, first double-click on the desktop computer icon, and then in the Open interface, click the top of the "Uninstall or change program" option; 2, then in the bounce out of the program and function, select the driver needs to uninstall (here to uninstall Realtek NIC driver as an example), find the name with Realtek Ethernet Controller name of the software, and then click on the right click to select "Uninstall", follow the on-

There are users in the use of WiFi sharing master to create a WiFi network will appear when the network card does not open the prompts, you can follow the following methods to deal with. 1. Check the wireless card switch is open There may be several ways to turn on the wireless card switch on your notebook, and here are two common types. The first is to hold down the notebook at the same

When using the network card, it is found that the signal of the NIC is not normal. The status of the signal can be detected using XP's "Wireless network Connection" or "wireless card" attached software. In XP, you can open a window that shows the status of a connection by clicking the Network Connection icon in the taskbar. If 4 or 5 green lines are displayed, the network is in good condition. If there are only 1 to 2, it means the signal is in a bad

For a 2.6 kernel, there is a struct pointer inside the Net_device,struct dev_mc_list *dev->mc_listBy accessing it, you can loop through all of the multicast MAC addresses.However, the new kernel (at least 3.10) has changed, insteadstruct netdev_hw_addr_list mc;We can obtain the corresponding data by directly accessing the MC, or we can take advantage of the macros provided by the Linux kernel.netdev_mc_count(dev)This macro can get the current total number of multicast MAC addresses, the specific
