can't change ssh config file

#1 Post by DebianNoob83 »

hi there. i'm trying to change some of the values in my ssh config file in order to harden its security,based on ssh hardening tutorials i've found online. but i can't seem to open ssh config through terminal even as root, still says permission denied.
also i can't change the file directly because its set to read only, what am i doing wrong here?

If you are accurate in your description, then yes it is peculiar. You should provide us with some basic information:
-File permissions. That can be achieved by typing into the terminal

Code: Select all

ls -la 
-Terminal output. What error is returned when you try to alter the contents of the file?
-What program do you use to edit the file? Most people use vi, vim or nano.

Even though it is generally not considered to be a good practice, have you tried staying logged on as the root in the terminal?
Lastly, have you tried shutting down the ssh service? I think that some services lock their configuration files when active.
