我使用telnet登陆服务器,但是,无论登陆是否成功,都会打印系统信息出来,这样我觉得有很多安全隐患,不知道是否可以屏蔽掉这些信息
信息如下:
login: jsz

Last login: Thu May 18 14:50:17 2006 from 222.70.223.114 on pts/2
Linux jsz 2.6.8-2-686 #1 Tue Aug 16 13:22:48 UTC 2005 i686 GNU/Linu

一键入密码之后就显示如上信息了。
刚开始telnet www.xxx.net后的系统我已经屏蔽掉了,
在/etc/issue.net文件里面,但是如上的信息就不知道在那里屏蔽了,还得继续麻烦大家,谢谢! |
