uptime, w, and who show nobody logged inI was working on a box for a client. They asked me to help. After fixing the problem, I checked to see if the client was still logged in. Here’s what I saw:
[root@p100:/var/log] # who [root@p100:/var/log] # w 9:21PM up 5:18, 0 users, load averages: 0.08, 0.09, 0.03 USER TTY FROM LOGIN@ IDLE WHAT
That’s wrong. You can’t issue a who or a w and get no users. You’re logged in. You should at least see you. uptime gave similar incorrect information.
Actually, you can be logged in and not seen. Here are the various things people have mentioned:
- screen will let you do this, using the deflogin off option in your screen rc. add a chmod 711 ~; touch .nofinger and you’re pratically invisible
My first thought was: someone has root’d this box.
So I asked on IRC and was told that it seems that my /var/log/wtmp is screwed. DOH!
So I logged out and back in again. Then everything worked:
[root@p100:/var/mail] # who dan ttyp1 Nov 1 21:24 (126.96.36.199) [root@p100:/var/mail] # uptime 9:50PM up 5:47, 1 user, load averages: 0.00, 0.01, 0.00
i’ve read the article ‘uptime, w, and who show nobody logged in’
then i try to find something like "screen" as stated on it :
screen will let you do this, using the deflogin off option in your screen rc.
So, can you explain me where exactly i must use screen rc? Is it like rc.screen or screen.rc or else? since i can’t finde rc like that. And second, the option "deflogin", how can i write it in my screen rc?
thanks for your answer

screen as in /usr/ports.
make search name=screen
I’ve also updated the article to include a link to the <A HREF="/screen.php">screen article</A>.
What is the maximum number for loadaverage in uptime? I am trying to script a simple utilization and I need to know that max
Thanks in advance.
My guess is there isn’t one.
Why does your algorithm need the maximum? What does your algorithm do that existing solutions don’t?
