开启Mac OS X ssh 服务器

====方式1: UI设置开启==============

系统偏好设置 => 共享＝>勾选允许远程登陆。

====方式2:手动设置开启==============

1. 配置文件路径：

/etc/sshd_config

2. 生成秘钥：

sh-3.2# ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/var/root/.ssh/id_rsa): 
Enter passphrase (empty for no passphrase): ［直接回车］
Enter same passphrase again: ［直接回车］
Your identification has been saved in /var/root/.ssh/id_rsa.
Your public key has been saved in /var/root/.ssh/id_rsa.pub.
The key fingerprint is:
97:e9:5a:5e:91:52:30:63:9e:34:1a:6f:24:64:75:af root@cuican.local
The key's randomart image is:
+--[ RSA 2048]----+
|       .=.X .    |
|       . X B .   |
|        . = . .  |
|         . + o   |
|        S = E    |
|         o . .   |
|          o .    |

|        . .      |

3.  修改配置文件

Port 22
#AddressFamily any
#ListenAddress 0.0.0.0
#ListenAddress ::


# The default requires explicit activation of protocol 1
Protocol 2


# HostKey for protocol version 1
#HostKey /etc/ssh/ssh_host_key

#HostKey /etc/ssh/ssh_host_rsa_key
#HostKey /etc/ssh/ssh_host_dsa_key
#HostKey /etc/ssh/ssh_host_ecdsa_key
HostKey /var/root/.ssh/id_rsa

4. 启动ssh服务。

which sshd //查找sshd的位置。

Mac 上sshd的位置在 /usr/sbin/sshd

在终端输入/usr/sbin/sshd即可启动sshd服务。
