Invisible user?
Posted by busfault on Sun 4 Feb 2007 at 19:40
I have used Linux for a while now, though I have yet to learn all of the intricacies of System Administrating. I occasionally run 'uptime' to see my loads, how long my system has been up, and users on. Now this has me puzzled because I was the only one logged onto my machine, yet it shows up as users 2 `uptime` reports:
Valhalla:/etc# uptime

I just tested something. Workstation with no network access, just me logged on at the console.
$uptime
22:06:44 up 8 days, 9:05, 1 user, load average: 0.16, 0.25, 0.23
I then start screen and open two 'screens':
$uptime
22:07:46 up 8 days, 9:06, 2 users, load average: 0.21, 0.23, 0.22
it sees two users, although I am the only one here. Maybe you have logged in at 2 VT (virtual terminals)?

Only one login connection. I am only connected via STTY0, which is the only direct connection that I have to the box, a "headless" system. I suppose that perhaps there is some connection that borked and is floating. I am thinking maybe that is why two pts/2 connections show up under who -a? I looked through my ps listing to see if any of the pts connections show up as a parent, which they don't. There aren't any other shells running either, besides the current login. If I am not even logged in, the STTY login shows '1 user' on the login screen.
