Hi Ronald,
Sorry about the seemingly abrupt responses last night, I was typing on
my phone. Did you get this sorted out?
Regards,
Nathan

So, did debug verbosity (-vvv) or specifying a port (-p 2222) help any to
understand the problem?

Try ssh - vvv? That should give a bunch more data...

I need some feedback from the group. By the way I have gone to
the Ubuntu and Internet forums and found answers all over the place
about this problem.
One of the sub-projects I am working on is to set up a Hadoop
testbed (single-node cluster) on Ubuntu 11.10 (just a stripped down
32 bit P5 loaded with hard drives). I am working from a paper by
Michael G. Noll, dated August 5, 2007 (last updated: June 29, 2012) .
The part where I am having problems is to get the SSH set up by
connecting to the local machine with the hduser user. I keep getting
the following message:
no4@no4-PCV-RX550-UC:~$ ssh localhost
ssh: connect to host localhost port 22: Connection refused
no4@no4-PCV-RX550-UC:~$
I have run through a number of steps to make sure I have both the
ssh server and client loaded, reloaded – working and running. But I
still run into the same error message. What am I missing?
Any help would be appreciated.
Thanks, Robin
