Dear Experts,
On a couple of CentOS 7 workstations I noticed that user "(unknown)" is
logged to local X11:
~]# last
...
(unknown :0 :0 Wed Oct 15 14:40 still logged in ...
~]# who
(unknown) :0 2014-10-15 14:40 (:0)
...
Of course, it is real user who is logged in, and his screen is locked
(after some time of inactivity).
Is it just me, or other people saw this? Can somebody comment on this? It
is quite likely that I just copied relevant to that person's account lines
into /etc/passwd, /etc/shadow, /etc/group, and /etc/gshadow from different
box. No, of course, not that bad, I indeed created the account, then just
copied password hash. But I used /sbin/groupadd and /sbin/useradd command
line utilities. Could that be the reason? If yes, are we to do everything
trough GUI on CentOS 7? What do you, clever people, do to copy account
from one machine (likely with different system, say, CentOS 6, or CentOS
5) to another (running CentOS 7)?
Thanks for all your answers.
Valeri
