SSH problem in hadoop installation
Hi,
Am trying to install Hadoop on a linux cluster(Fedora 12).
However, am not able to SSH to localhost and gives the following error.
*ssh_exchange_identification: Connection closed by remote host*
I know this is not the correct forum for asking this question. Yet it could
solve a lot of my time if any of you could help me.
Thanks,

By client I mean the machine from which you are trying to ssh. By server I mean the machine which you want to login. Can you paste the contents of your /etc/hosts, /etc/hosts.allow, /etc/hosts.deny files.

Hi,
@sourabh: its a simple cluster in lab. So nothing like server and
administrator..
We have always passwords with us only.

Hi,
Do you've access the to the server. If you don't you'll have to ask the administrator to check if the client's IP address is present in the server's /etc/hosts.allow and make sure it is not present in the /etc/hosts.deny file
There could be other reasons too like the Fingerprint Keys getting corrupted but this should be the first step and only then you should look for other options.
Thanks,
Saurabh Dutta
