Constructing Grid on Fedora

I have a cluster of several PCs, each is running Fedora, either 14 or 15.
I want to make this PCs grid enabled, so I installed globus (
http://www.globus.org/ ) and made a server with a global IP and with
a subdomain. My main objective is to be able to run parallel
programming (mpi), harnessing the idle CPUs of onlines nodes.
The stage at a moment, I have successfully set up simple-CA and the
GSI of the server.
Globus commands works fine, for example:
$ globus-hostname-lookup fedora.org
Resolving address (fedora.org)...
Numeric address: 67.40.49.xxx
Expected DN suffix: /CN=host/hoxx.trippy.org
Your identity: /O=Grid/OU=GlobusTest/OU=simpleCA-localhost.localdomain/OU=localdomain/CN=
Enter GRID pass phrase for this identity:
Creating proxy ............................................ Done
Your proxy is valid until: Wed Nov 2 05:01:04 2011
I tried but failed to copy a file from one node to a server.
$ globus-url-copy file:///home/username/Grid/Codes/cpi.c gsiftp://domainname/
The message is as follows,
error: globus_xio: Unable to connect to domainname:2811
globus_xio: System error in connect: No route to host
globus_xio: A system call failed: No route to host
It seems something to do with the port 2811. Checking /etc/services
of the server gave the port number and the protocol
root$ less /etc/services | grep gsi
gsigatekeeper 2119/udp # GSIGATEKEEPER
gsiftp 2811/tcp # GSI FTP
gsiftp 2811/udp # GSI FTP
gsidcap 22128/tcp # GSI dCache Access Protocol
As I do not have any experience, I have no idea how to fix it.
I mainly rely on internet searching, but still can not find the answer.
I expect from this list some suggestions or any comment.
Thank you very much in advance.
