Activating ssh server is a must for your ubuntu box. This howto shows the installation and setup for the openssh client and server, while you are running Ubuntu 13.10 Saucy Salamander.
First of all update your system (note, this could take a long time)
Install the client:
My client was already installed and updated. 8)
Now install the server:
Edit (as sudo) /etc/ssh/sshd_config, search for line (Port 22) and change 22 in a number greater than 2048, this will secure your system just a little. When you'll try to connect to your ubuntu box using ssh client you shall specify the number of port you have selected.
now let's restart the server
Let's give a try:
develop@develop:~$ ssh -l develop localhost
ssh: connect to host localhost port 22: Connection refused
I activated the server on a different port, as I shown obove. So let's give another try:
So the server is working
See you soon,
