> Hi,
> 
> I installed mpich2 under ubuntu using synaptic package manager and 
> everything went fine. The problem I'm getting is I can't mpiexec as a 
> regular user , only as root
> 
> I have an /etc/mpd.conf file set as chmod 600
> I have a /home/user/.mpd.conf file
> I have run mpd & as user and/or root
> but I get this error:
> 
> /shared/bin/mpdroot: open failed for root's mpd conf 
> filempdtrace (__init__ 1171): forked process failed; status=255

> I had to change a couple of things to get mpiexec to work as user:
>     run mpd --daemon as root
>     chown user\: /etc/mpd.conf
>     chown user\: /tmp/mpd2.console_root
> to get mpiexec to work.
> 
> This is not a good solution. Does anyone have a good explanation for 
> this behaviour. My user wants to user the root mpd , why?
