ssh in network

[Michael Havens]

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

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

If the connection is seen on the host (but has some problem due to FQN
