[Hadoop-common-user] Query

I tried to set up hadoop with cygwin according to the
paper:http://developer.amazonwebservices.com/connect/entry.jspa?externalID=873
But I had problems working with dyndns.I created a new host
there:prerna.dyndns.org
and gave the ip address of it in hadoop-ec2-env.sh as a value of MASTER_HOST.
But when I do bin/hadoop-ec2 start-hadoop the error comes:
ssh:connect to host prerna.dyndns.org,port 22:connection refused
ssh failed for [email protected]
Also a warning comes that:id_rsa_gsg-keypair not accesible:No such
file or directory though there is this file.

Thanks
Prerna

I didn't try to run on cygwin, but you may need to install a ssh.

Already installed.
but still ssh to the newly created host in dyndns site is not working

ssh -i path to id_rsa prerna.dyndns.org..

It wasn't too difficult though I do not remember the details.
Maybe searching the WWW does reveal the details
