Today test Selenium call Firefoxdriver, the driver can not run in a no-interface environment, need to remotely connect to the server to operate, so there is the process of installing teamviewer below.Previous attempts have been made many times and have not run up TeamViewer8, the main problem is that when the installation is started, there is no "accept" button at the time of authorization and cannot continue to run it. After unremitting efforts, fina
If you use Remote Desktop to connect to the past to open TeamViewer, when you quit "Remote Desktop", the external network with TeamViewer connection will appear this problem.Workaround:Do not use the remote connection in the past to open the TeamViewer, directly on the computer to manually turn on the TeamViewer on the
TeamViewer please add a link descriptionTeamViewer is a remote PC support/control and Screen-sharing tool. You can remote control a partner's desktop to give online assistance, or can show your screens to a customer without Wo Rrying about firewalls, IP addresses and NAT.TeamViewer is a remote Access application this grants you access to other computer and work on it as if it were the one yo U is in front of. The first thing you has to install
System environment: CentOS 7.3.10.0-693.el7.x86_64TeamViewer version: v12.0.85001 (RPM)1, TeamViewer download
# wget https://dl.tvcdn.de/download/version_12x/teamviewer_12.0.85001.i686.rpm
2, yum Installation
# yum-y Install teamviewer_12.0.85001.i686.rpm
Installation is complete if no accidents occurPS: In the case of "yum" requiring a missing public key, the public key file needs to be downloaded and the key is imported as an administrator using
options for L3 protocols to meet the needs of various advanced network applications.
2. Comparison with L2 Switching
The distributed L3 switch supports popular routing protocols and organically combines the advantages of L2 switches with vrouters. l3 switches can control IP addresses, making it easier to build large-scale local area networks.
3. Differences from centralized layer-3 core exchange
Distributed layer-3, which can be managed to each grass-roots network, greatly reducing the backbone

Differences from centralized layer-3 core exchangeDistributed layer-3, which can be managed to each grass-roots network, greatly reducing the backbone burden. The network management capability is balanced, replacing the core network architecture with stacked, large capacity, high backboard bandwidth, and expensive centralized management.

recently, in the deployment of the relevant DNS system services for the company's customers, for resource scheduling services, but the customer export lack of public IP address, can not easily manage this server, began to think of using teamviewer to do transit, penetrate the intranet, but in the CentOS environment, According to the TeamViewer official manual to try to install several times, did not, always
Teamview network can penetrate intranet, and support LAN. Client has a PC side, there are mobile terminals, interested friends to search engines themselves. (Sunflower only support networking through the intranet, the client has a PC side, there are mobile terminals, interested friends to search engines themselves)
This article only describes the PC side of TeamViewer and the operation of the mobile side

The querystring. parse method in node. js is described in node. jsurl. parse.
Method description:
Converts a string to an object. To put it bluntly, the parameter string on the url is converted into an array object. (See the example)
Syntax:
Copy codeThe Code is as follows:Querystring. parse (str, [sep], [eq], [options])
Receiving parameters:
Str string to be converted
Set the separator for sep. The default value is ''
The eq value assignment operator. The default value is '='
[Options] maximum
386, it is the CPU level.
I586-is a 586-level computer, including the first generation of pentum mmx cpu, AMD K5, and K6 system CPU (socket7 pin.
I686-pentum 2 after the Intel system CPU and K7 after the CPU level belongs to this 686 level.
You can query your CPU level through the/proc/cpuinfo file.
II. View CPU information
We can view CPU information through the/proc/cpuinfo file.

Just like the address path in my log, let Index.php?action=onedo=two

With this class, we can encode the string in the previous example:Querystring Qs = new querystring ("PG", "Q ");Qs. Add ("Kl", "XX ");
common in kernel programs. This is different from the case where we scold goto as a zombie when learning programming, this is related to the event trigger mechanism of the kernel. In this example, when the buffer read is full, we use goto to provide a uniform exit, so that the entire program looks neat and easy to read.
