windows server 2012 R2 install openssh
windows install ssh
linux itself uses ssh without installation
1. Download
Visit the Openssh official website and follow the instructions Select the appropriate installation package according to the number of bits of the operating system
After entering the official website, select the appropriate installation package according to the number of bits of the operating system. However, 64-bit systems can also support 32-bit installation packages. For the 64-bit system here, I installed the 32-bit installation package.
2. Unzip the downloaded installation package to the C:/Program Files/ directory
Open the powershell terminal and enter the folder containing the ssh executable exe file cd C:\OpenSSH-Win32 \OpenSSH-Win32.
3. Install ssh service
Enter the following command in the powershell terminal:
powershell.exe -ExecutionPolicy Bypass -File install-sshd.ps1
After successful installation, the following will appear:
4. Configure ssh service
Open port 22 in the firewall: Enter the following command in powershell:
netsh advfirewall firewall add rule name=sshd dir=in action=allow protocol=TCP localport=22
Start ssh service
net start sshd
5. Add environment system variables
will contain ssh Add the path to the executable exe file (in my case: C:\Program Files\OpenSSH-Win32\OpenSSH-Win32) to the environment system variables.
Finally open cmd or powershell, enter ssh and the following image appears, which means the installation has been successful.
6. Set the sshd service to start automatically at boot
Open "Server Manager" in sequence -> "Tools" - "Service"
Enter the service list interface and find the OpenSSH SSH Server service
Change the openssh authentication agent in the picture below Do the same as in the picture above.
Windows that come with their own ssh service (such as windows 10) enable the ssh service
1. Client installation
Start-> Applications and Features-> Optional Features-> Add Features
There is an option for OpenSSH client in the list
Click to install OpenSSH client
After installation, you can use Windows PowerShell Directly use the ssh command
2. Server installation
Start-> Applications and Features-> Optional Features-> Add Features
There is an OpenSSH server in the list Options
Click to install the OpenSSH server
After the server is installed, you need to perform some configuration
3. Server configuration
Run Windows as administrator PowerShell
Enable SSHD service
Start-Service sshd
Set the service to start automatically
Set-Service -Name sshd -StartupType 'Automatic'
Confirm whether the firewall is open
Get-NetFirewallRule -Name *ssh*
Check whether OpenSSH-Server-In-TCP is enabled After the configuration is completed for True
, other clients can use ssh to connect to windows. The username and password are the username and password of windows

Java code can run on different operating systems without modification, because Java's "write once, run everywhere" philosophy is implemented by Java virtual machine (JVM). As the intermediary between the compiled Java bytecode and the operating system, the JVM translates the bytecode into specific machine instructions to ensure that the program can run independently on any platform with JVM installed.

The compilation and execution of Java programs achieve platform independence through bytecode and JVM. 1) Write Java source code and compile it into bytecode. 2) Use JVM to execute bytecode on any platform to ensure the code runs across platforms.

Java performance is closely related to hardware architecture, and understanding this relationship can significantly improve programming capabilities. 1) The JVM converts Java bytecode into machine instructions through JIT compilation, which is affected by the CPU architecture. 2) Memory management and garbage collection are affected by RAM and memory bus speed. 3) Cache and branch prediction optimize Java code execution. 4) Multi-threading and parallel processing improve performance on multi-core systems.

Using native libraries will destroy Java's platform independence, because these libraries need to be compiled separately for each operating system. 1) The native library interacts with Java through JNI, providing functions that cannot be directly implemented by Java. 2) Using native libraries increases project complexity and requires managing library files for different platforms. 3) Although native libraries can improve performance, they should be used with caution and conducted cross-platform testing.

JVM handles operating system API differences through JavaNativeInterface (JNI) and Java standard library: 1. JNI allows Java code to call local code and directly interact with the operating system API. 2. The Java standard library provides a unified API, which is internally mapped to different operating system APIs to ensure that the code runs across platforms.

SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
