All you need to make a NetBSD system into a web server is a permanent
connection to the internet, and a httpd daemon.  NetBSD comes with
{C}SLIP and PPP, which is all you need to connect to an Internet
Service Provider offering those services.  

I don't know why your friend thought that you would need additional
software.  Perhaps his experience is with older UN*X systems like
SunOS where you had to obtain SLIP and/or PPP separately.

After you have a net connection, all you need is a httpd daemon.
I know nothing about this.  But most should compile and install
easily on a NetBSD system.
