What directory is linux .ssh in?

The path to the .ssh folder under linux, etc.

1.The .ssh folder under linux is in ~, directly cd ~/.ssh

2.tpThe watermark image format processed by the gd class is png

3. If you open other people's websites on the front end, you can open it locally If the same code segment appears, it may be dynamically added by js, just delete the original duplicate;

Note:

First for the root user:

" ~" represents the directory of the root user. It can be understood that each user has his own directory. When logging in as the root user, his personal directory is /root

. Secondly, for other ordinary users:
" ~" represents the logged-in user's personal directory, but this user's personal directory is located in the home directory under the root directory.

Related expansion introduction:

Secure Shell (Secure Shell, referred to as SSH) is a protocol used for secure remote login and other secure network services on unsecured networks.

SSH was developed by the Network Working Group of the IETF; SSH is a security protocol based on the application layer. SSH is a more reliable protocol designed to provide security for remote login sessions and other network services. Using the SSH protocol can effectively prevent information leakage during remote management. SSH was originally a program on UNIX systems and quickly expanded to other operating platforms. SSH, when used correctly, can close holes in your network. SSH clients are available for a variety of platforms. Almost all UNIX platforms—including HP-UX, Linux, AIX, Solaris, Digital UNIX, Irix, and others—can run SSH.

Traditional network service programs, such as ftp, pop and telnet, are inherently unsafe because they transmit passwords and data in plain text on the network. People with ulterior motives can easily intercept these passwords. and data. Moreover, the security verification methods of these service programs also have their weaknesses, that is, they are easily vulnerable to "man-in-the-middle" attacks. The so-called "man-in-the-middle" attack method is that the "middle-man" pretends to be a real server to receive the data you send to the server, and then pretends to be you and sends the data to the real server. After the data transmission between the server and you is changed by the "middleman", serious problems will arise. By using SSH, you can encrypt all transmitted data, so that "man-in-the-middle" attacks are impossible, and it can also prevent DNS spoofing and IP spoofing. An additional benefit of using SSH is that the transmitted data is compressed, so the transmission speed can be accelerated. SSH has many functions. It can not only replace Telnet, but also provide a secure "channel" for FTP, PoP, and even PPP.
