Changing Ssh Keys

Hello-

After setting up Raspberry Pi w/Kali Linux, I did change root password but while trying to change ssh keys evidently I screwed up, as when I ran:

cd /usr/local/src/re4son-kernel_4*

repeatedly recv'd

bash/bin... (no directory found?)

error message???

Have no idea if my keys were changed and/or properly updated or not.

Obviously a noob, I have no idea what I'm doing; thanking you in advance for your kind, generous help.

Great source of info, and on behalf of all the others who don't speak up please allow me to

thank you very much!!!

Respectfully,

Pepsy
