WebTTY！太酷了！
这真是一件很Cool的事，在Web上操作Linux，请访问下面这个链接：
http://19.testape.com/webtty_page.php
于是你会看到页面中间的红色，一个小操作系统启动了，红色的最下方是一个bash-2.05b#
试着输入一下命令吧。
bash-2.05b# uname -a
Linux (none) 2.6.18 #2 Mon Dec 29 19:47:06 UTC 2008 i686 GNU/Linux
命令支持的不多，好像只是一个单机版的虚拟机，一但你打开网页时就起动一个。当然，也不排除其完全是假的，因为太简单了，一切都可以fake出来。

反应太慢了，打一个字母要隔几秒才出现在屏幕上！
ps/free/top/iostat/cpuinfo啥都木有
看看我的开源项目，应该比他这个要好，彩色终端和vi的支持，好像只有我这个可以
我这个软件也叫 webtty ，支持彩色终端，但目前对 vi 的支持不够，还要努力。。

欢迎试用，谢谢支持!
的确！你的更不错哦。
啊，太酷了，看上已经比较接近实用了，如果可以解决显示速度慢的问题就更好了：）
转眼就体会到vi支持不够是啥意思了-_-
哈哈，直接输入了
