UFW (Uncomplicated Firewall) setup

UFW seems to be the best choice for a CL controlled firewall. iptables seem too complicated to me and Firestarter is designed for GTK, which is not installed, and, probably never will be.
So far the plans are:

1. Install and configure UFW
2. Install and configure SSH
3. Install Samba, Transmission
4. Create a user account which will host all required services and will be used to ssh to and to control things
5. Configure /etc/hosts to speed up things a bit
6. Write up the /etc/samba/smb.conf  

Have disabled the root account:

$ sudo passwd -l root

1: Install and configure UFW 

$ sudo apt-get install ufw

$ sudo ufw allow proto tcp from 192.168.1.101 to any port 22

Allows TCP connection to port 22/ssh from my MainPC (192.168.1.101)

$ sudo ufw deny

Disables all other connections Inbound or Outbound.

$ sudo ufw enable

Enables the firewall and adds to startup script.

2: Install and configure SSH on both PCs

$ sudo apt-get install ssh

Surprisingly enough it did not have to be configured. Security out of the box setup is questionable however.

3:  Install Samba, Transmission

$ sudo apt-get install samba samba-common smbclient samba-doc swat transmission-cli transmission-daemon transmission-common

Steps 4,5 and 6 require further reading, so will edit this later.
