Linux under SSH using RSA Authentication login Macox

Due to the needs of the project, my side of Ubuntu often requires SSH access to another MacOS. Each time you enter a password a bit annoying, think of RSA public key and key authentication method. As is said in all tutorials, native execution [email protected]:~$ ssh-keygen-t RSA copies the public key to MacOS's/tmp and gives others read access: [email protected]:~$ SCP. ssh/id_rsa.pub [email protected]:/tmp [email protected] ' s password: id_rsa.pub                                    100%  390     0.4kb/s   00:00 so I landed on MacOS, and there was some preparation to do. There is no. ssh directory under the MacOS User directory. let alone. SSH under Authorized_keys file. dev-mini:~ devone$ mkdir. sshdev-mini:~ devone$ sudo chmod 740/tmp/id_rsa.pubdev-mini:~ devone$ sudo cat/tmp/id_rsa.pub >>/home/devone/.ssh/authorized_keysdev-mini:~ devone$ sudo chmod 740/home/devone/.ssh/authorized_ keysdev-mini:~ devone$ Exit For later SSH access I add a profile in this machine [email protected]:~$ CD. ssh/[email protected]:~/.ssh$ Vim Config Add the following host Dev-minihostname Dev-mini.localuser devoneidentityfile ~/.ssh/id_rsa after SSH access mac OS, I can directly [email  protected]:~/.ssh$ ssh Dev-mini But let's enter the password. I think it should be a sshd_config configuration problem on Mac OS. Not Ssh_config Oh. Enter the password dev-mini:~ devone$ sudo vim/etc/sshd_config modified as follows:# $OpenBSD: sshd_config,v1.89 -/ Geneva/ .xx: -: theDtucker EXP $
