Hello Friends!! I am new to Linux forum and old windoze user who is keen to start using Linux forever now! I love it, it is far better. Does anyone know EXACTLY how to take a .config file from sshd and can one just change the code in it? I assume using the cp command as one wants backup.(?) Incidentally, where should backup file be stored? Using new Ubuntu 2021. Thank-you awesome friends!

It would be helpful if you were a little more specific. A config file for what and is it a system file or a file in your /home/user directory? Are you using sshd to access the machine or trying to modify an sshd config file? Backup files are generally stored on a separate physical drive since one purpose is to have a backup if the drive in use fails.

If what you mean is ~/.ssh/config then mine looks something like

Code:

Host f
HostName foo
User user1

Host b
HostName bar
User user2

Then I can just ssh f and it will translate to ssh user1@foo.
