Send email on ssh login
提问by Tech4Wilco
I want to make sure everytime someone is login into my server I receive an email saying:
我想确保每次有人登录我的服务器时，我都会收到一封电子邮件：
ALERT Shell Access on: Tue Jun 16 11:04:10 CDT 2009 user123 pts/0 2009-06-16 11:04
ALERT Shell 访问时间：Tue Jun 16 11:04:10 CDT 2009 user123 pts/0 2009-06-16 11:04
So I put this code:
所以我把这个代码：
echo 'ALERT Shell Access on:' `date` `who` | mail -s "Alert: Root Access from `who | cut -d"(" -f2 | cut -d")" -f1`" [email protected]
in the .bashrc.
在.bashrc.
Why I don't receive any emails?
为什么我收不到任何邮件？
Thank you for your help, J

.bashrc is executed when bash is run as a interactive non-login shell, which is not the case when you ssh. Add the same code in .bash_profile which should be run when the shell is a login shell
.bashrc 在 bash 作为交互式非登录 shell 运行时执行，而 ssh 则不是这种情况。在 .bash_profile 中添加相同的代码，当 shell 是登录 shell 时应该运行
Note: Many distributions source .bashrc from .bash_profile, I may be wrong and the issue may not be about .bashrc / .bash_profile
注意：许多发行版从 .bash_profile 获取 .bashrc，我可能错了，问题可能与 .bashrc / .bash_profile 无关
