It usually manages more than 130 Linux physical hosts, so it is difficult to deploy applications to find out the IP information of each host!

There are two files in the main modification area of shell.

1. Modify/etc/issue (when operating on site in the IDC, you can know the host application according to the display prompt information)

2. Modify/etc/motd (when connecting to the remote terminal through ssh, you can follow the terminal prompts to know the host application, etc)
