I was googling the 'no route to host' and found a suggestion to add a route that poimts to the routerr with the command 'sudo ip route add 192.168.1.0/24 dev eth0'. So I thought that sounded good but after I did not only could I not ssh out of the computer but I could no longer ssh into the computer. I then tried to remove the route with the command 'sudo ip route del 192.168.1.0/24 dev eth0', but that didn't help any. I just realized that the ip address is wrong.... my router is 192.168.0.1 but:

sudo ip route add 192.168.0.1/24 dev eth0

sudo apt-get install openssh-server

openssh-server is already the newest version.
openssh-server set to manually installed.

You run a ssh server and you use a ssh client as a user.

# ssh myusername@targetserverIP

# grep Root /etc/ssh/sshd_config <--------------- 'root' not in file

Make sure you used "Root" like
# sudo grep Root /etc/ssh/sshd_config

there it is..... PermitRootLogin yes

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:

Hmmm? Go look in var log and see what this system logs to:

# sudo tail /var/log/messages
# sudo tail /var/log/syslog

bmike1@Michaels-PC:~$ sudo tail /var/log/messages;sudo tail /var/log/syslog

Add this to /etc/hosts.allow:

/etc/hosts.allow looks:
ALL : 127.0.0.1
sshd : 192.168.0.0/24, 78.207.132.32
This example shows an external address you might want to use to connect from outside your internal network (once you open or port forward port 22).

This is the hosts.allow file that I added. Does this look right?

ALL : 127.0.0.1
sshd : 192.168.0.0/24, 192.168.0.1/24, 192.168.0.2/24, 192.168.0.3/24, 192.168.$ <this goes on to x.y.z.10/24>
#shows address to use from outside of network#, 78.207.132.32
Now the /etc/hosts.deny file:

ALL : ALL
Do this and your apt-get/aptitude will be fixed:
# sudo apt-get install make
make is already its current version
