PuTTY and WinSCP Configuration
# PuTTY Configuration
Host name: bitnami@<domain name> (or IP address if no domain is there). Port 22.
Config -> Connection -> SSH -> Auth -> set PPK file for authentication (convert the PEM to PPK in PuTTYgen)
Config -> Connection -> SSH -> Tunnels -> forward source port 8888 to localhost:80, required to connect to phpMyAdmin from local machine.
# WinSCP Configuration
Change connection protocol to SCP instead of SFTP
In Advanced -> Environment -> SCP/Shell, change shell to "sudo su -", whilst using "bitnami" user for login.
