Hi,

I don't know much about ports and networking things.  I am  using cygwin 
under Windows XP. I followed the cygwin directions for installing 
sshd,and I believe its  running, ie



$ ssh localhost
Last login: Sun Jan 31 09:37:39 2010 from 127.0.0.1:0.0


and ...



I    4220       1    4220       4596    2 1007 02:33:34 /usr/bin/bash
     2152       1    2152       2152    3 1007 09:37:35 /usr/bin/xterm
     5440    2152    5440       3928    4 1007 09:37:38 /usr/bin/bash
     2628    5440    2628       3468    4 1007 09:53:03 /usr/bin/ssh
     1608    3684    1608       5752    ?   18 09:53:05 /usr/sbin/sshd


I have an (open source) process I would like to run  that in theory 
creates and manages a cluster of computers using sshd under cygwin  The 
configuration file examples use ports 9000 and 9001,and I went with 
these, the configuration files look like:

<name>fs.default.name</name>
<value>hdfs://localhost:9000</value>
</property>
<property>
<name>mapred.job.tracker</name>
<value>localhost:9001</value>
</property>


However, when I run it, port 9000 isn't cooperating:



10/01/31 09:46:34 INFO ipc.Client: Retrying connect to server: 
localhost/127.0.0.1:9000. Already tried 0 time(s).
10/01/31 09:46:36 INFO ipc.Client: Retrying connect to server: 
localhost/127.0.0.1:9000. Already tried 1 ti



when I netstat  -an     I get::

     127.0.0.1:1327         ESTABLISHED
  TCP    127.0.0.1:1324         127.0.0.1:1328         ESTABLISHED

  TCP    127.0.0.1:5152         127.0.0.1:1366         CLOSE_WAIT
  TCP    127.0.0.1:5354         0.0.0.0:0              LISTENING
  TCP    127.0.0.1:6000         127.0.0.1:2874         ESTABLISHED
  TCP    127.0.0.1:27015        0.0.0.0:0              LISTENING

port 9000 and 9001 don't show up. what do I do next? Do I need to do 
something to activate them,ot configure the process to run on other 
ports? I guess that ssh is a tcp process, and that works  only on 
certain ports?

Thanks,
Brian
