Explanation of Mac connecting to remote servers through SSH in different terminals

Mac uses Shell (Terminal) SSH to connect to the remote server

Prerequisite: You need to have the IP address, port number, account and password of the server you need to connect to

1. First open the terminal, then enter sudo su - Enter to enter the root directory

2. Then enter: ssh -p port number server username@ip (for example ssh -p 22 [email protected]) and press Enter. You will be asked to enter yes or no to confirm whether to connect. Enter yes and press Enter.

3. Then enter the user password on the server and press Enter

4. Now you have entered the directory of your account on the server, which means the connection is successful. Finally, enter sudo su - to enter the root directory of the server and perform operations.

Mac remotely connects to the Linux server through the built-in Terminal SSH

1. When using Windows, Xmanager and the Xshell tool in it are very convenient, but they do not support OS. I learned on the Internet that Mac can remotely connect to Linux server through SSH protocol directly in the terminal.

2. The command format for connection is very simple:

$ ssh [email protected]

ssh space username@target machine IP address

It is worth noting that there may be two situations here

The password set by the backend buddy contained a field: p0st. I later asked someone for help and found out that the circle was a 0, not a capital O. So when the password is wrong, you may also see permission denied . Be sure to "check" the password and username.

Then the second situation is also encountered more frequently on the Internet. I have already set it up before, so after the password is correct, I can connect successfully directly:

permission denied or authentication denied , which means insufficient permissions

Here you need to modify the value of a configuration file to pass

vi /etc/ssh/ssh_config

Click i to enter the edit state and set PasswordAuthentication to yes

Then remove the # sign in front of PasswordAuthentication to make it effective.

Then shut down the ssh service using the command

sudo launchctl unload -w /System/Library/LaunchDaemons/ssh.plist

Then restart and remove un

sudo launchctl load -w /System/Library/LaunchDaemons/ssh.plist

Enter a command to view the restart status

sudo launchctl list | grep ssh

If there is a line with -0 or something, it is successful

Then reconnect and it should be able to connect
