You can access the server through either SSH or SFTP using your usual username and password. In your homedirectory you will find a directory called public.www, all files and directories within this special directory will be available on the web at https://med.hosted.hr.nl/<employee_code>/, all other files in your homedirectory are private and are not reachable on the web. Furthermore you can manage your database using the web interface at https://sql.hosted.hr.nl.
