issue.net & motd

新开了阿里云的机器之后机器 ssh 过去的默认提示是:

Welcome to Ubuntu 14.04.4 LTS (GNU/Linux 3.13.0-86-generic x86_64)

 * Documentation:  https://help.ubuntu.com/

Welcome to aliyun Elastic Compute Service!

可以加一些内容。一共两个与之相关:

  • issue.net : Display a banner message before the password login prompt.

  • motd : Display a banner message after the user has logged in.

设置 issue.net

在下面文件中添加想要添加的内容

# vim /etc/issue.net

Text to ASCII Art Generator (TAAG) 上面生成了 ASCII Art。

Ubuntu 14.04.4 LTS

  ______ _____  _____ 
 |  ____/ ____|/ ____|
 | |__ | |    | (___  
 |  __|| |     \___ \ 
 | |___| |____ ____) |
 |______\_____|_____/ 

改 config

# vim /etc/ssh/sshd_config

搜索 Banner 并取消掉它的注释

#Banner /some/path

需要 reload ssh

# service ssh reload

motd

Message of the Day 的意思,内容放在 /etc/motd,另外还可以用 UpdateMotd 动态生成的内容,参考 UpdateMotd

这里先不深究,而是直接 apt-get install landscape-common。landscape-common 会显示一些机器的信息。
