I want to thank everyone for contributing to solving the implementation
problem I was having. It seems in the end it was an "operator" problem. To
summarize the results:
- regarding sshd port change - uncomment port, and change the port number
entry in /etc/ssh/sshd_config. Restart the sshd service. Update
/etc/sysconfig/iptables to reflect the port number change from 22 to the
port number specified in / etc/ssh/sshd_config, then restart iptables
service.
- PasswordAuthentication no - this requires an additional option to be
change, "ChallengeResponseAuthentication no". Having made both of these
changes, causes the login to abort is a valid ssh key is not specified.
Again many thanks to everyone.

Subject: sshd options - centos 5.3
I have installed cento 5.3. I enabled the ssh deamon. I have found that 2
options that I normally use does respond as I expect. Has anyone else had
similar problems with the following options in sshd_config:
- Port 6666 - if I set the port to anything other than 22 (default), using
ssh -p6666 name at servername, does not work. Yet if I leave keep the default,
then ssh name at servername allows me to login.
- PasswordAuthentication no - if I set this option to "no" (default is
"yes"), and my ssh key is either missing or in error, I will be prompted for
user system login password. If this is set to "no", it should not allow me
to login if I have not ssh key specified or in error. Has anyone else run
into this problem.
Is there a workaround? What are my options? Please help.
