On Most of the Linux distribution IPV6 are enabled by default, which may cause your Internet are workding slow, so If your NE Twork do not supportor don't setup IPv6 network, you should better toDisable IPV6Protocal in the Linux system and it maybe increate your Web browsing speed or network security. So what do I-disable IPV6 on Linux operating system? This arti
To install Linux on a virtual machine for practice, a very important step is to connect the network, the following:1. Set the virtual machine to Internet mode as NATNote: In the Red box, select2. Set the IP acquisition mode of VMNET8 virtual network in host local machine to DHCP3, set the IP acquisition mode of Linux as DHCP (take centos6.4 as an example)(1) Input command: Setup popup box(2) Select network

Have always thought that their own Linux also said the past, in fact, has not kept up with the ever-changing application needs.There are no ready-made documents to look at, too many mistakes. However, after years of accumulation, it is possible to organize an accurate document.Native IP settings:# static interfaceAuto Eth0Iface eth0 inet StaticAddress 192.168.127.11Netmask 255.255.255.0Network 192.168.127.0Broadcast 192.168.127.255Gateway 192.168.127.
In the proxy mode below, set the agent for Eclipse, native manual several modes are not, do not set the proxy.1. Problem: Under the proxy mode setting, MAVEN or marketplace are not connected to the extranet . To view the error message (in the Console error log field in Eclipse):.................. System Property Socksproxyhost isn't set but should be 172.15.18.80 ...........According to this hint, the problem is that when setting up a network proxy, only the HTTP protocol is set, and HTTPS and
commands operate as follows:
See if the host has a br0 bridge and it does not exist;
Add a NIC named Eth1 to the test01 and configure the IP172.18.18.36/24;
If there is already a default route in test01, delete it and set 172.18.18.1 as the default route L
Connect the test01 container to the br0 on the previously created bridge;
This process is similar to the previous process of using IP command configuration, pipework is actually code written in Shell.Pipework in fact
server of the VMNET8 (NAT) virtual network and cannot be modified manually, so the virtual system cannot communicate with other real hosts on the local area network.3.host-only (host mode)In some special network debugging environments, it is required to isolate the real environment from the virtual environment, then you can use the host-only mode. In host-only mode, all virtual systems can communicate with each other, but the virtual system and the real network are separated.Settings: Whether y
