I previously had Raspbian Wheezy, on which my SSH worked fine. However, on my new version of Jessie I cannot connect the SSH from my laptop to my Pi. I have checked that the SSH is enabled and running, and I am almost certain that there is no problem with the firewall. Does anyone have a solution to my problem?
Is your Pi connected via ethernet LAN?
If so, enter the command in Pi:
Using a SSH client (e.g. Putty), enter the IP address, leave the port no as 22, and connect. You should be prompted to enter your Pi password (by default it is "raspberry")
At this stage you should have successfully SSHed into Pi.
I'm using Jessie and no problem accessing Pi via SSH using the method above. If you are accessing via a Wifi dongle then there are different settings you need to perform.
