IOU安装的license问题

loopbackying

1.L2IOU 单独安装的时候可以正常运行。
2.L3IOU单独安装的时候，不能运行，后来改了license 为B0ACC48944F31BD4 ， af369ed2c95da783后可以正常运行。
3.L2IOU和L3IOU一起安装的时候，L2IOU提示错误了。错误提示如下：
root@lry-iou:/home/lry/桌面/IOU# ls
L2IOU  L3IOU  start  TOP

4.网上搜到“....license一个美丽的谎言”的帖。看到说“用root建立/etc/hostid这个文件”。然后在ubuntu里面搜索etc的文件出现了很多个etc文件，进的是哪个etc文件夹？而且怎么查看绝对路径？终端要到那个文件夹下才能创建hostid文件对不对？不知哪个啊。Linux第一次接触。。求具体解决过程。。我想先安装好iou做实验。懂的都要说说啊。。感激不尽
