20 years ago, I should have started offering dial-up, virtual server, and hosting services as a local mini ISP (internet service provider).
What I owned is a set of simple equipment, such as a 16-port modem pool, a hardened FreeBSD as RADIUS, DNS, WWW, and mail server, Moxa Async Server as network access server or RADIUS client, a 10BaseTX switch hub, and a Cisco 1601 router.
The WAN connection is a 64Kb leased line and a Class C public IP address.
The business was closed after one and a half years of operation. It was closed because of the dot-com bubble.
That’s a good old day story!
