====== How to setup SSH on Ubuntu ======
Consider that 192.168.1.1 is a host, and "denis" is a user on the host side.

1. Installing server
  sudo apt-get install ssh


2. Setting up server
  sudo gedit /etc/ssh/sshd_config
<file>
Port 2000
PermitRootLogin no
AuthorizedKeysFile	%h/.ssh/authorized_keys
</file>

  sudo service ssh restart


3. Setting up client

  ssh-keygen -t dsa
(empty answer for every question)

  ssh-copy-id "denis@192.168.1.1" -p 2000


4. Close server access for user without dsa-authorization:
  sudo gedit /etc/ssh/sshd_config
<file>
PasswordAuthentication no
</file>

  sudo service ssh restart
 
5. Connect from mc:
   open panel`s "shell-connection" paste needed machine denis@192.168.1.1. Type password - enjoy.
