1. 配置檔案路徑：

/etc/sshd_config

2. 生成祕鑰：

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): ［直接回車］
Enter same passphrase again: ［直接回車］
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

The key's randomart image is:

3.  修改配置檔案

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
# HostKeys for protocol version 2
#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


# Lifetime and size of ephemeral version 1 server key
KeyRegenerationInterval 1h
ServerKeyBits 1024


# Logging

SyslogFacility AUTHPRIV
#LogLevel INFO


# Authentication:


LoginGraceTime 2m
PermitRootLogin yes
StrictModes yes
#MaxAuthTries 6
#MaxSessions 10


RSAAuthentication yes
PubkeyAuthentication yes

4. 啟動ssh服務。

which sshd //查詢sshd的位置。

Mac 上sshd的位置在 /usr/sbin/sshd

在終端輸入/usr/sbin/sshd即可啟動sshd服務。
