[mpich-discuss] mpich hangs

[Syed. Jahanzeb Maqbool Hashmi]

I feel sorry to not able to provide more information and keeping the thread
long.
But still there is no ufw in my /usr/sbin.

Actually, I am using an ARM development board (ORDROID-X2) which has ubuntu
linaro image. I suppose that due to space limitation, this image may not
include additional utility features like firewall but only the core
functionality.
