Hello:<br> I installed mpich2 on a ubuntu 6.06 machine, then share the install directory with a FC5 machine by using NFS. These two machines were connected to each other directly by a cable. The ubuntu machine is connected to a router which connects to internet. <br><br> My problem is that "when I 'mpdcheck -s' on ubuntu machine, "mpdcheck -c ubuntu-machine port " on FC5 succeed. But I can't do it reversely. I mean "when I 'mpdcheck -s' on FC5 machine, "mpdcheck -c fc5 port" failed with the following error:<br>--------------------------------------------------------------------------------------------<br>Traceback (most recent call last):<br> File "/home/xuying/mpich2-install/bin/mpdcheck", line 103, in ? sock.connect((argv[argidx+1],int(argv[argidx+2]))) # note double parens<br> File "<string>", line 1, in connect<br>socket.error: (113, 'No route to
host')<br>--------------------------------------------------------------------------------------------<br><br>please help!<br><br>---------------------------------------------------------------------------------------------<br><br><br><br><p>
