每次要做什麼東西，跑到虛擬機裡邊來很麻煩，要想轉出去還得用Ctrl＋Alt，如果是作開發的話再打開 終端，當然也可以直接啟動在text mode下，但是那個模式下邊窗口很小，滾動之後上邊的東西就看不見了，所以我一致在尋找通過Windows的CMD操作虛擬機中的Linux的方法。終於找到了，那就是使用telnet。
1. sudo apt-get install xinetd telnetd
2. 安裝成功後，系統會有相應提示（我使用的是7.10）
--------- IMPORTANT INFORMATION FOR XINETD USERS ----------
The following line will be added to your /etc/inetd.conf file:
telnet stream tcp nowait telnetd /usr/sbin/tcpd /usr/sbin/in.telnetd
If you are indeed using xinetd, you will have to convert the
above into /etc/xinetd.conf format, and add it manually. See
/usr/share/doc/xinetd/README.Debian for more information.
3. sudo vi /etc/xinetd.conf並加入以下內容（該文件本身存在，只是加入幾行即可）：
# Simple configuration file for xinetd
#
# Some defaults, and include /etc/xinetd.d/
defaults
{
# Please note that you need a log_type line to be able to use log_on_success
# and log_on_failure. The default is the following :
# log_type = SYSLOG daemon info
instances = 60
log_type = SYSLOG authpriv
log_on_success = HOST PID
log_on_failure = HOST
cps = 25 30
}
includedir /etc/xinetd.d
