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.
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
