在看到介绍omnitty，其称“
linux系统管理员利器，重复劳动必备”，可以批量通过ssh登录多台linux机器，并且多台机器同时执行一样的命令。对于这个功能描述就很吸引人的，所以下来看看。
omnitty：
依赖：rote-0.2.8.tar.gz
我下载的是当前最新版本omnitty-0.3.0.tar.gz，编译安装很正常：

现在可以启动omnitty了。
omnitty的用法还是比较郁闷的，首先f5添加一个主机，添加类似如下“root@172.16.81.191”，然后让你输入密码，登录之后再添加第二个主机，继续添加第n个主机。添加完毕之后，假设有17个主机，可以按f2、f3上下选择不同的主机，在每个主机上面做不同的操作。
如果想批量，在所有主机上都做一个操作，必须按f1,打开菜单，按t选中所有的活动主机，然后按f7启动批量操作功能（右瞎角红色闪烁!!! multicast mode !!!），这时候，你的操作在所有机器上都起作用。可以f2/f3上下切换看看效果。
这个工具还是有很多缺点的：不能保存主机列表（左侧是主机列表），下次启动必须再挨个f5添加；如果链接断了，不能再登录了，只能删除重添加才能登录。有待完善的太多了。
