SSH is based on Key verification and accelerates SSH connection, and key verification ssh connection speed
Authentication Method for SSh service logon:
Password-based security verification
1. When the client initiates an ssh request, the server will send its own public key to the user.
2. the user encrypts the password based on the public key sent from the serve

Our school has an electronic reading room with 24 computers. When we applied for an Internet connection through ADSL, we all said that ADSL is a broadband network, but we can use it on our own. The Internet speed is always low. When many people access the Internet, I download a software that uses about 6 kbps, Which is slower than ISDN. My original
When the USB device is connected, the USB system automatically detects the connection and identifies the data transfer rate it uses. USB uses the method of increasing the pull-up resistor on the d+ or D-line to identify low-speed and full-speed devices .USB supports 3 types of transfer rates: low-speed transmission of
user information of the destructive software.
Workflow: First of all, the local MAC through ARP spoofing broadcast to the local area network, so that the workstation in the local area network is mistaken for the gateway. This process will cause the LAN to disconnect from the Internet connection and the game to the server. When the user restarts the game and makes an account login, The account information does not go directly to the proxy server via

Before setting up, let's explain what duplex mode is.
Duplex: The way information can be sent in two directions simultaneously between two points.
The meaning of duplex can be two-way transmission at the same time, as usual in the phone call like that. Devices such as walking on a phone are half-duplex or simple duplex.
Set the steps as follows:
1, on the desktop to find the "Network Neighborhood" icon, right click, select "Properties";
2, the new window will see the "Local

The first approach: we can speed up the broadband connection. The specific mode of operation is as follows: First, we press the keyboard Win+r shortcut key to open the computer's running window, then we enter the regedit in the Run window and click Enter, and then we navigate to [hkey_local_machine]--[software]--[ Policies]--[microsoft]--[windows], add an item named [psched], add a DWORD value [NonBestEffor
Background information:Currently, the configuration management of the servers in the project has all migrated from puppet to Ansible, and the slow problem of SSH channels, which had previously been considered not to be troubling, is clearly exposed.Because many times need to update hundreds of servers at the same time, there are many servers and Ansible host is not the same IDC room.Accidentally found an article, referring to open SSH controlmaster and persistent socket

Because the company is in the education network, access to the company's servers at home through ADSL is very slow, but the remote desktop program does not provide a place to set up proxy servers, in this case, we can use a third-party proxy tool to solve the problem of using proxy for Remote Desktop. Proxy can improve the connection speed of remote control, and can also remotely control the server when the
In ASP, Join and Array are used to speed up the character connection. Today, I saw a lot of test data on the Internet, so I was too lazy to read it and copied the conclusion.
For example
Dim a (10000), I, t
T = Timer
For I = 0 to 10000
A (I) = CStr (I)
Next
Response. Write Join (a, vbCrLf)
