If you are a VPS or Dedicated server user, you can set or change the Welcome message.
The welcome message is stored in /etc/motd folder. There is generally no actual command to change or modify. So, you have to change it manually.
Step-1: Login to your Linux server as root.
Step-2: Now we use vi command to edit the motd file. Enter the command below and hit enter.
vi /etc/motd
Now you can edit or remove the welcome message of your Linux server. Press i key to insert mode and edit.
Step-3: After editing, Press ESC to revert back to command mode. Now type :wq and press enter to save the file!
Finally restart the SSH terminal.
service sshd restart
Done!
