將 sshd, ssh-keygen 複製到 ARM target board /usr/bin/
將 libz.so 複製到 ARM target board /usr/lib/

執行 sshd, 一定要用絕對路徑＠＠＠＠
/usr/bin/sshd

會依次出現下面的錯誤訊息

/usr/local/etc/sshd_config: No such file or directory
    將 sshd_config 複製到 ARM target board /usr/local/etc
Privilege separation user sshd does not exist
    在/etc/passwd 中添加下面這一行
    sshd:x:74:74:Privilege-separated SSH:/var/empty/sshd:/sbin/nologin
Could not load host key: /usr/local/etc/ssh_host_rsa_key
Could not load host key: /usr/local/etc/ssh_host_dsa_key
Could not load host key: /usr/local/etc/ssh_host_ecdsa_key
Disabling protocol version 2. Could not load host key
sshd: no hostkeys available -- exiting.
    ssh-keygen -t dsa -f /usr/local/etc/ssh_host_dsa_key
    ssh-keygen -t rsa -f /usr/local/etc/ssh_host_rsa_key
    ssh-keygen -t dsa -f /usr/local/etc/ssh_host_ecdsa_key
Missing privilege separation directory: /var/empty
    mkdir -p /var/empty


再執行 /usr/bin/sshd, 應該就好了。可以用 ssh 測試看看

ssh root@192.168.199.99（target board 的 ip）
然後輸入 root 密碼就就可以了.
