Portable Wi-Fi dual-nic configuration + Windows 7 multi-user remote connection + some companies' network environment restrictions, wifiwindow7
The company only provides several machines, and the machines are limited to connecting to the internal office network at the same time,
On the other hand, we have a lot of manpower, and the project is tight, while the other party's application procedures are troublesome,
I asked the other party's network manager about the solution.
In my attempt, I finally found a solution;
Pre-resolution problem:
1. In Windows 7, only one remote user is allowed. When a second user logs on, the current user is automatically exited. When several users use the same machine at the same time, the user needs to be used in different time periods, extraordinary war;
2. The machine has only one Nic and the development environment is disconnected from the Internet,
Solution:
1. You can remotely connect to this machine ..... to develop ...... many remote redirects. In this way, you need to crack the single-user limit. The multi-user patch of window found on the internet is UniversalTermsrvPatch. Download and install the patch, and restart the patch to enable multi-user logon, it does not affect the current user, but it is found that when some software is used by a user on a local machine + n remote users, such as chrome, the remote user can open but cannot see the rendering problem, in fact, the page is already in the visible area (right-click to see the chrome menu), that is, the window cannot be seen. When the user on the local machine is exited, chrome is no problem when it is used by all remote users;
2. Use portable wifi to add a second network card to the machine. One problem here is that Windows has heard that (I have not studied it carefully. If you can specify the network card that goes through the Internet, the network card can go through the Intranet, or multiple external networks can be specified independently.) When routing is processed, problems may occur. Its logic is to use the recently used route, rather than directly identifying the Intranet, that is the Internet, and the correct request is sent to the correct Nic. No, in this case, in order to ensure that the intranet development environment is normal (window prompts that this is an Internet connection, in fact, it is not accessible to the Internet, this is a big problem. I haven't studied it for the time being.) if I don't change the internal network card, I just need to do my work on wifi: Write the ip address and mask of ip4 on the wifi network card directly, if none of the other settings are configured, the Wi-Fi is connected to the vro (Internet route), but it cannot be connected to the network. All Internet requests will be automatically sent to the Intranet Nic. the output result of route print in cmd shows that there is only one route. however, this machine can be connected to other machines in the same domain on the Internet route. even though it cannot be connected to the Internet, other machines can remotely access the Internet and copy files or something. It is very convenient to remotely use mstsc;
Here, you need to ping the Intranet for one remote user to keep its route always active. Otherwise, sometimes the gateway cannot be found.
These studies solve the problem of no Internet machine in a development environment shared by many people.
Which network environment should be selected during Windows 7 system installation on the lan?
Home Network
Linux Server dual-network card 192 and 22 network segments, I can ping some ip addresses in the 22 network segment, and some cannot be pinged, I can set it
Check the route table settings and check whether there are any problems with the route. Generally, you can ping your own CIDR block. If you set two NICs, you need to set the route table when you ping the third network segment.
