Re: [Ubuntu Oregon] Ubuntu Hour
So, did debug verbosity (-vvv) or specifying a port (-p ) help any to understand the problem?

Yep. Try ssh -p . If that doesn't work, please show the full firewall rules.

Re: [Ubuntu Oregon] Ubuntu Hour
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.
