However, a password is required every time, and a manual reconnection is required when the connection is timed out. Reconnection.
The first is to save the password input problem, you need to create a key, enter on your command line:
local:~ yourname$ ssh-keygen -t rsa
and press Enter in turn, enter the password, this password has nothing to do with the SSH account password.
The whole interface looks similar:
local:~ yourname$ ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/u/kim/.ssh/id_rsa): [Enter]
Enter passphrase (empty for no passphrase): 【First passphrase】
Enter same passphrase again: 【Second passphrase】
Your identification has been saved in /u/kim/.ssh/id_rsa.
Your public key has been saved in /u /kim/.ssh/id_rsa.pub.
Then transfer the key file to your SSH account:
local:~ yourname$ cd ~/.ssh
local:~ yourname$ cp id_rsa.pub authorized_keys
local:~ yourname$ scp -p ~/.ssh/authorized_keys hrothgar:.ssh/
The last step will prompt you to enter the password of the SSH account, not the password you just created the key.
If the last step prompts an error, it is usually because of a remote permission problem.
You need to log in to the remote machine as root, create a relevant directory for this SSH account, and set permissions:
set in the Home directory of the SSH account login:
