Auswipe, I believe they are talking about ids that show up when you do a who -a that are "old".

I see this on my systems as well. With who -q, I have 6 users logged in, but my who -a shows many other ids that are latent. Folks who are not logged in, but have been in the past.

Here are a few examples of what I think he is talking about.

user 1 pts/13 Oct 28 15:14 old 24395 id= 13 term=0 exit=0
user2 ttyp3 Nov 11 16:44 old 5342 id= p3 term=0 exit=0


Is that what you are talking about yls177???
