Install lsof, then you can:
lsof -i | grep LISTEN

You will see all the processes listening on network ports

For a web server, the only service you need is apache, but you will also
need a way for people put their files up for publishing and possibly
editing apache config etc.

Consider using ssh and have the students use sftp or psftp.exe or
filezilla's SFTP2 mode to transfer files to the webserver.
