This question already has an answer here:
scp command between two machine i.e, A(192.168.1.220) and b(192.168.1.242).
When I'm running command from A(192.168.1.220)
sudo scp success.tar.gz firstname.lastname@example.org:/home/user/bkp
it keep asking me for password for remote user
What should I do in order to execute the
scp command without entering password?
