There are a number of solutions available on the Internet, mainly in the following ways:1 shut down Windows Firewall;2 Turn off IPv6 or set IPv4 preferences, specifically: In Device Manager, Show hidden devices, disable a network device beginning with "Teredo", Increase in Eclipse.ini file (last line parameter) OpenFile-vmargs-djava.net.preferipv4stack=true 3 Turn off the virtual NIC (virtual network adapter created by VMware, VirtualBox, etc.);My first do 2, 32 steps, have no success, f

When installing Oracle, the system often prompts the IP address assigned by DHCP. If you ignore the IP address, you can also install it. However, if the IP address is changed in the future, many dependent services may not be started. To solve this problem. You can install the loopback Nic. However, using the Add hardware wizard on Widnows 7 as usual does not allow you to install the device manually, as shown in: Does Widnows 7 no longer support

1, Linux network interface of literacy(1) Naming of network interfacesThere is no naming convention, but the definition of a network interface name is generally meaningful. For example:Eth0:ethernet, typically used for Ethernet interfaces.Wifi0:wifi is a wireless LAN, so wifi0 generally refers to a wireless network interface.Ath0:atheros, generally refers to the Atheros chip contains the wireless network interface.A shorthand for lo:local, generally referred to as a local

1. About the digital loopback mode In the digital loopback mode, the receive signals are connected internally through Multiplexers to the corresponding transmit signals. This mode allows testing of serial port code with a Single DSP device; the McBSP records es the data it transmits. 2. About the Clock Stop Mode The clock stop mode supports the SPI master-slave protocol. If you will not be using th

Sometimes a standalone block device is required, and loopback is a convenient option to create the following waysDD If=/dev/zero of=./loopback_file bs=1m count=1000losetup/dev/loop0./loopback_fileFirst set up a file of the specified size as the actual storage space, and then associate it with/DEV/LOOP0, the loop device seems to have a number of restrictionsYou can create a file system on it after the creation is complete, etc.When you need to remove,

Group Policy is applied to a user or computer in some way, depending on where the user and computer object is located in Active Directory. However, in some cases, the user may need to apply the policy only based on the location of the computer object. To apply a Group Policy object (GPO) only based on which computer the user is logged on to, you can use the Group Policy loopback feature. More information To set the user configuration for each comput

From: Http://wiki.wireshark.org/CaptureSetup/Loopback @ ++ Alternatives A required cial network sniffer called commview (from tamosoft) allows to capture packets on the localhost network adapter but it dissects fewer protocols, so you can capture packets with commview and save them into a file and open it with Wireshark. An other alternative is to add a route to your local machine going through the Network Gateway: Route add Wit

There are several virtual machines on the local machine. To allow virtual machines to communicate with each other without a network, you need to add a network adapter for Microsoft loopback adapter. It is easy to add in XP, and it takes a long time for me to find it in RC, I don't remember what I clicked during the search process, and the location I already looked for was reversed.
