Errors while trying to run rsh swingle -n true
Unexpected response from swingle:
--> connect to address 192.168.3.1: Connection refused
connect to address 192.168.3.1: Connection refused
trying normal rsh (/usr/bin/rsh)
If your .cshrc, login, .bashrc, or other startup file
contains a command that generates any output when logging in,
such as fortune or hostname or even echo, you should modify
that startup file to only print such a message when the
process is attached to a terminal.  Examples of how to do
this are in the Users Manual.  If you do not do this, MPICH
will still work, but this script and the test programs will
report problems because they compare expected output from
what the programs produce.

The test of rsh <machine> true  failed on some machines.
This may be due to problems in your .login or .cshrc files;
some common problems are described when detected.  Look at the
output above to see what the problem is.

If the problem is something like 'permission denied', then the
remote shell command rsh does not allow you to run programs.
See the documentation about remote shell and rhosts.

The ls test failed on some machines.
This usually means that you do not have a common filesystem on
all of the machines in your machines list; MPICH requires this
for mpirun (it is possible to handle this in a procgroup file; see
the documentation for more details).

Other possible problems include:
The remote shell command rsh does not allow you to run ls.
See the documentation about remote shell and rhosts.
You have a common file system, but with inconsistent names.
See the documentation on the automounter fix.
