debian登陆信息修改

2015-01-15 tech linux 6 mins 1 图 2366 字

一般我们ssh登陆debian会出现以下的信息。

Linux kelu.org 3.18.1-x86_64-linode50 #1 SMP Tue Jan 6 12:14:10 EST 2015 x86_64

修改和添加的方法很多。在此记录一下。

登陆前提示信息文件是 /etc/issue 和 /etc/issue.net. 登陆前的信息我们不管了，就来看登陆后的信息好了。

##start######## /etc/update-motd.d/10-uname #######################

motd的意思是message of the day——每日消息

接下来是

/etc/ssh/sshrc ssh登陆之后会加载里面的内容。

/etc/bash.bashrc 值得注意的是，screen时候也会加载这个文件。

在/etc中的配置文件，会对所有用户生效。如果只希望对当前用户做自定义的配置，就在用户目录下进行配置。

我最后改成了这样：

/etc/update-motd.d/10-uname 文件：

echo "YUKI.N > SELECT シリアルコード \n         FROM データべース \n         WHERE コードデータ \n         ORDER BY 攻性情報戦闘 \n         HAVING ターミネートモ
ード"

/etc/motd文件：


YUKI.N > If you are reading this,
         then I'm probably no longer myself

YUKI.N > When this message apprears,
         it means that you, me, Suzumiya Haruhi, Asahina Mikuru and
         Koizumi Itsuki are all present.

YUKI.N > That's the key.

YUKI.N > This is ermegency escape program.
         To activate it, press enter.
         Otherwise press any other key.

         If you activate it,
         you will be a given time to repair space-time continuum.
         However there's no guarantee of your safe return.

YUKI.N > This program can be start only once.
         Once execute it will be erased.

         If you choose not to activate it, it will also be erased.
         READY?
