In Raspian Jessie it should be activated allready. If not enable the SSH server by opening the raspi-config:

$ sudo raspi-config

In 8. Advanced Options you can activate SSH.

Look up your gateway:

$ netstat -r -n

Find you IP address:

$ ip addr

Give the Raspberry Pi a static IP address. Open the interfaces file:

$ sudo nano /etc/network/interfaces

Add these lines after “face eth0 inet dhcp”:

Or:

  # Ethernet
  auto eth0
  allow-hotplug eth0
  iface eth0 inet static
    address 192.168.0.121
    netmask 255.255.255.0
    gateway 192.168.0.1
    dns-nameservers 8.8.8.8 8.8.4.4
    

Save and quit, ctl+o, Return, ctl+x.

Disable the DHCP-Client:

 $ sudo service dhcpcd stop
 $ sudo systemctl disable dhcpcd       

Restart ethernet:

 $ sudo ifdown eth0
 $ sudo ifup eth0

Or/and reboot:

 $ sudo reboot

One can login from your computer with:

$ ssh pi@192.168.0.099

or with XWindows support:

$ ssh -XY pi@192.168.0.099

PW: raspberry

If the host key verification failed, one can remove the old key with:

$ ssh-keygen -R 192.168.0.099

And with

~.

one can terminate a broken ssh session.
