[SciPy-user] cow socket.error

[Cory Davis]

Hi All,
Can any one tell me what is going on here?
It seems that some socket error is stopping my cluster from starting up.

In [6]: slave_list = [ ('slave.number.one',2345),
('slave.number.two',2345)]
 
In [7]: cluster = scipy.cow.machine_cluster(slave_list)
 
In [8]: cluster.start(timeout=200)

    163         print 'servers running!'
    164
 
TimeoutError: None

And when I look at /tmp/crud2345, which is where the output of the ssh
command is piped to I get ...

[cory at slave.number.one tmp]$ cat crud2345
starting server on slave.numer.one:2345

Any ideas?

Cheers,
