w and who don't list users in FreeBSD 9.0 and 9.1

[Istvan Gabor]

Hello:

I have both FreeBSD 9.0 and 9.1 on two different computers.
w and who commands do not list logged in users in any of them
(either for root or a regular user).

The output of w is:

root@:/root # w
 4:56PM  up 10 mins, 0 users, load averages: 0.18, 0.26, 0.20
USER       TTY      FROM                      LOGIN@  IDLE WHAT
root@:/root #

And the output of who:

root@:/root # who
root@:/root #

Why is this and how can I fix it?

Thanks,

Istvan

ps: I tried google search but w and who are not good search terms.
