Just remove it:

# apt-get remove openssh-server
# apt-get add openssh-server
# /etc/init.d/ssh start

That means that the connection times out.   Are you trying to ssh as root?
Sometimes root is excluded from connecting via /etc/ssh/sshd_config?

# grep Root /etc/ssh/sshd_config

Okay, you can do (verify ssh):
# /etc/init.d/ssh status
or
# netstat -antp |grep ssh
or
# ps -ef |grep ssh

Try your connection again!

# ssh yourname at targetprintserverip

If the connection is seen on the host (but has some problem due to FQN
(/etc/hosts) or /etc/hosts.allow files, it will be logged in either:

# tail /var/log/messages
# tail /var/log/secure

Okay we see the ports open, so we don't have a firewall in the way.

What is in your /etc/hosts.allow and /etc/hosts.deny on the ssh target?

Okay you can post to the Ubuntu boards, or google the exact *distro
version*[uname -a] with your question and find a great number of
people who have
already answered your question.
