OMPI got that IP address from somewhere; probably by a name resolution

Hi Sun
i forgot to add that once you've called gethostname(), you can
determine the length of the name by using strlen() on your array
'name'.

parameter, specifying the length of the array your passing
as the first parameter. The name of the host will be placed in the
array, but it will truncated after len characters.
I don't know how to determine the length of the host

I've tried gethostname() by myself but an abnormal result generated.
My code is:

OMPI doesn't use ssh by default to launch a daemon local to mpirun -
instead, we locally fork/exec the orted.
The problem here is that OMPI doesn't realize that you are launching
on the local machine. This is usually caused by confusion when IP
resolving the hostname returned by get
Hello,
I have two questions about ssh and details follow.
Questions:
Is there any way to prevent the usage of ssh on my local desktop and
