In any regular Linux distribution "~/" should point to the users home (as in the environment variable "$HOME"). If the "~/.ssh" directory does not exist then you can create it as regular user with
Code:
install -d ~/.ssh -m 0700
and then create the file with
Code:
( umask 077 && touch ~/.ssh/config )
* 'man ssh_config' specifically holds the "Host" and other declarations should you want to read about it.
