设置 ssh 登录服务器时的提示文字
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在 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 reloadmotd
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。
