Star How Many Linux Users Are There? Will We Ever Know?
Linked by Amjith Ramanujam on Fri 15th Aug 2008 04:15 UTC, submitted by computerishcat
Linux The traditional market share numbers would say that Linux is currently at less than 1%, but some more recent numbers suggest that it might, in fact, be almost even with the Mac. This all brings the question of how many Linux users are there really? Unfortunately, we may never know. Certainly, there is no way of knowing currently, but it should be possible to at least get a rough estimate.

Counting IPs wouldn't work because a lot of hosts hide behind a NAT firewall. However you could count MAC addresses.


Unfortunately you cannot. MAC Addresses are not transmitted past the first router. After that only IP is transmitted (not counting special cases like packet encapsulation for VPN traffic and such).

Once on the local segment ARP is used to match up IP address (or whatever protocol is being used if not IP) to MAC address.

Exactly. But this wouldn't stop firefox from sending your Mac address as an anonymous usage statistic if you chose to do so. It could send the mac address of the default network interface, along with the operating system and other stats. Obtaining the mac address of a network interface is trivial enough for a program running locally.
