CYGWIN sshd 服務正在啓動 .
CYGWIN sshd 服務已經啓動成功。
ubuntu下面使用靜態ip方法：
http://os.51cto.com/art/201210/361003.htm
主要是設置一下文件：
1. 啓動虛擬機Ubuntu系統，打開終端，利用如下命令打開並編輯網絡接口配置文件：
sudo vi /etc/network/interfaces
2. 編輯文件如下：
auto lo iface lo inet loopback # Assgin static IP by eric on 26-SEP-2012 iface eth0 inet static address 192.168.91.200 #change to your static IP netmask 255.255.255.0 #change to your netmask gateway 192.168.91.2 #change to your getway #We must specify dns-nameserver here #in order to get internet access from host dns-nameservers 192.168.91.2 auto eth0
