Package: xrdp
Version: 0.5.0-2
Severity: important
User: debian-...@lists.debian.org
Usertags: debian-edu
I discovered this while testing xrdp with Debian Edu Wheezy. I would
log in using rdesktop, use the desktop for a while, and suddenly the
rdesktop window would just disappear. The cause was the killer package,
killing all non-niced processes of users that no longer was logged in.
And the reason why it mistook my session as a no longer active login was
that xrdp fail to register the session in /var/log/utmp. Thus 'who' did
not show that I was logged in, KDE would not get a notification from
shutdown and killer would kill all the users processes every hour. I
assume it also will cause other problems. :)
Normally the display manager (kdm,gdm, etc) will register the session
with utmp and wtmp when the user log in, and remove/update it when the
user log out. But xrdp fail to do so. Please change xrdp to register
all active sessions in utmp and wtmp.
This is the console output from pstree and who, showing that there is an
active session, that do not show up in who when I run who from a root
shell logged in via ssh:
