Hosting server at home: secure services over the DSL connection

Broadband connections with up to 10 Mbit/s upstream allow to run the Internet server not only at a hoster. ZDNet explains how to become their own ISP and offering Internet services from the home server.

The server rooms of the large hosting providers such as 1 & 1, Strato and Host Europe look impressive. Many thousands of servers, usually in 19-inch rack format are installed in a confined space in the shelves. So, for example, hosts Strato over four million domains. Assuming three million .de domains in the Strato-out data centers, so are the 25 percent of German Internet – measured in domains.

This stratovolcano is not responsible for the loss of 25 percent of the German Internet, including the power supply was secured with a diesel generator. For its operation Strato requires a permit from the German Air Traffic Control (DFS). The amount of hot exhaust gases can be dangerous for the approaching jets in Berlin.

The fact that the hosting business in the last two decades has developed so rapidly, mainly because that either firms or for individuals willing were inexpensive Internet connections, which offered enough bandwidth in the upstream, to operate a public server at their location itself.

That has now changed. ADSL2 + connections there are between 800 and 1000 kbit/s upstream, VDSL offers the German Telekom with up to 10,000 kbit/s. Even with a standard ADSL connection – possibly an extra charge – almost always 512 kbit/s are offered. Meanwhile, the DSL provider goes on to offer the maximum speed at no extra charge, which allows the line.

While depending on the cable length often must accept restrictions on downstream, the upstream usually reaches full speed. This is because the upstream DSL is modulated in a lower frequency range than the downstream. A great length and a small cross-section of the local loop (ULL) makes it less noticeable than in the upstream downstream.
