1. 查明登陆端口和登陆人
|
1 2 3 4 5 |
$ who secure :0 2015-07-22 03:03 (:0) secure pts/0 2015-07-23 00:27 (192.168.176.1) secure pts/1 2015-07-23 00:29 (:0) secure pts/2 2015-07-23 01:44 (192.168.176.1) |
2. 通知登陆用户将要关闭他
|
1 |
$ echo "I will close your connection" > /dev/pts/2 |
3. 关闭用户连接
3.1. 关闭某用户某链接
|
1 2 3 4 |
#安装fuser包 $ yum install -y psmisc #关闭某ssh会话 $ fuser -k /dev/pts/2 |
3.2. 关闭指定用户所有链接
|
1 2 3 4 |
#查看ssh登录用户 ps aux |grep sshd #关闭指定用户所有链接 kill -9 xxx |
4. 验证是否已经关闭
|
1 2 3 4 |
$ who secure :0 2015-07-22 03:03 (:0) secure pts/0 2015-07-23 00:27 (192.168.176.1) secure pts/1 2015-07-23 00:29 (:0) |
