求救：改了环境变量后不能登录系统了

唉，搞了一天总算是把软件装上去了，但改了环境变量后重启不能登录系统了，肯定是环境变量改得有问题，大神们帮我看看吧，昨晚搞到凌晨3点实在是顶不住了

就是这在里不管用什么账号都登录不了，输入完密码确定后过屏幕一黑又回来这里了

请问下大家，我刚把别人的bashrc改完进系统运行swb 提示这些：
[eda@cad]$ swb
License lookup failed: Cannot connect to license server system.

The license server manager (lmgrd) has not been started yet,

the wrong port@host or license file is being used, or the

port or hostname in the license file has been changed.
Feature:swb_all

* feature is "swb_all"

* version is "2013.03"

* STROOT is "/home/eda/synopsys/sentaurus/bin/.."

* hostname is "cad"

* display is "/dev/pts/0"

* user is "eda"

我把hosts里面加入了我的主机名 cad啊，怎么还会这样
127.0.0.1localhost localhost.localdomain localhost4 localhost4.localdomain4 cad
::1localhost localhost.localdomain localhost6 localhost6.localdomain6 cad

请问你解决了吗?我也出现这个问题

Thanks.......
