I have a raspberry pi which for a given user I can directly logon to the machine and I can also putty in.But then I connect an Ethernet between the pi and Ubuntu laptop, execute ip addr add 10.3.4.21/24 dev eth0, and then ssh myuser@10.3.4.21, and it asks me for a password, but states Permission denied.Why?
Password is denied under certain circumstances
ssh;password;authentication
