ssh登录自动发邮件提醒

大前提：

因涉及到发邮件，debian下需安装exim4并可对外发邮件，centos则需安装mailx,sendmail。

方案1，对所有用户生效，创建文件

vim /etc/ssh/sshrc

加入以下内容

#!/bin/bash
[email protected]
mail -s "notification:user $USER login from ${SSH_CLIENT%% *}" $yourmail <<EOT
 the ip information : http://www.123cha.com/ip/?q=${SSH_CLIENT%% *}
 login date: `date +%Y/%m/%d" "%H:%M:%S`
 if this is not you , please contact xxx for help.
EOT

方案2，不影响他人，只针对自己的账户

vim ~/.bashrc

添加

echo 'ALERT Shell Access on:' `date` `who` | mail -s "Alert: Root Access from `who | cut -d"(" -f2 | cut -d")" -f1`" [email protected]
