Re: [OpenAFS] Multiple logins

Quoting Dirk Heinrichs :


... Is it possible to prevent users from logging in more than once ...


No, you can't. ...


Thought so. A workaround may be to install different desktop  
environments and applications on some hosts.



Which desktop env. is it that makes problems?


KDE, although I don't plan to use it at the site; it's too slow over  
the 2.5Mbps WAN links.



Maybe using another one is an option.


The current plan is to use Xfce, although I assume that I will see  
many of the same problems as with KDE (most of the apps will be the  
same).



OTOH, why can they start it up on the other host at all? There's no need
to install one in the first place since users can login using ssh with
X11 forwarding and their windows will popup on their local X server display.


Unfortunately, the staff aren't that knowledgeable and it must be  
possible to use the other workstations independently anyway. It's just  
that sometimes one of the buildings is understaffed and personnel find  
it very convenient to simultaneously login to hosts on different floors.


Cheers,

Jaap

And then there's VNC.
