What kind of internet connection do I need? 2 MBit? 4 MBit? 1 Mbit?

Well – I had to face that question the last days. So I started to look at the services hosted on my machines:

• Webserver
• Mailserver
• Fileserver / FTP
• DNS services

I have to admit that a 4 MBit SDSL Line sounds delicious, but is it really necessary? As I am running ntop I could have a look at the bandwidth eaters of my network. The only service eating bandwidth like hell is the fileservice because of the malware distribution.

My ISP offers a cheap but good sdsl line at 2 MBit, which is more than sufficient for everything I do there if I place my transfer machine outside of my network which I will do.
