mickey (who is logged in as root) tries to use goofy's account to ssh into goofy.com.
root@mickey:/#su goofy && ssh goofy.com
however this fails to login goofy on goofy.com, instead: goofy@mickey:/$ (only su goofy worked, so goofy exits:
goofy@mickey:/$ exit exit Permission denied (publickey).
I'd expect the permission error for any user other than goofy. How can I do
su goofy ssh goofy.com
in one line?
