==Additional Resources==
*My true production domain name is computerisms.ca. Since I find it confusing to have the test and the real environment be the same name, computerisms.com will be the domain we are building. I already have ownership of the name

==Physical Hardware==

<h4>Windows Workstation - adminlian.computerisms.com</h4>
*required for testing and configuration
*configured to run in a "work" network environment, and enable discovery.
*configure ip address to be 192.168.26.100/gw=192.168.26.1/dns=192.168.26.10
*dns won't work yet, this is not a problem now.
*In this case I will be using Windows 7 SP1 freshly installed and updated on a Virtual Machine installed on my:

<h4>SSH Client - worklian.computerisms.com</h4>
*generate an ssh key (ssh-keygen -b 2048 -t rsa)
*in this case I will be using my ubuntu workstation

<h4>Digital Signage Remote - dslobby.computerisms.com</h4>
*An ubuntu virtual machine
*configure with IP address 192.168.26.25
*No special config required; by the time you need this, everything else will be in place

<h4>Firewall - porchlian.computerisms.com</h4>
*computer does need to be reliable, but not smart. Use an old workstation.
*this computer must have at least 2 network cards. larger networks with multiple subnets will probably need at least 3
*in this case I am using a very old dell dimension with 3 NICs
*install debian testing (jessie)
*create the file /root/.ssh/authorized_keys and put your public ssh key in it.
*cp /etc/vim/vimrc /root/.vimrc
**edit /root/.vimrc and find the line 'set compatible'; uncomment it and change it to 'set nocompatible'
*edit /root/.bashrc, enable colours and any other personal preferences
*set apt repositories to contain contrib and non-free (optional, if needed for drivers)
*apt-get install ssh ntp rsync tcpdump nmap
*apt-get remove rpcbind nfs-common
*mkdir /root/scripts
*configure external eth0 interface as 192.168.25.15/gw=192.168.25.1/dns=192.168.25.1
*configure internal eth1 interface as 192.168.26.1/255.255.255.0
*configure internal eth2 interface as 192.168.27.1/255.255.255.0

<h4>Server - houselian.computerisms.com</h4>
*this will be the workhorse of the network. This will be the PDC and lots of other things
**for a network of one for testing, I am sure any p3 or better will work fine.
**in a production environment you will need to split this into multiple machines
*in this case I am using a ~10 year old HP rackmount server
*install debian testing (jessie)
*create the file /root/.ssh/authorized_keys and put your public ssh key in it.
*cp /etc/vim/vimrc /root/.vimrc
**edit /root/.vimrc and find the line 'set compatible'; uncomment it and change it to 'set nocompatible'
*edit /root/.bashrc, enable colours and any other personal preferences
*set apt repositories to contain contrib and non-free (optional, if needed for drivers)
*apt-get install ssh ntp rysnc build-essential bind9
*apt-get remove rpcbind
*mkdir /root/scripts
*configure your resolv.conf to use 'nameserver 127.0.0.1'
*configure eth0 interface as 192.168.26.10

<h4>Backups - shedlian.computerisms.com</h4>
*this computer really does not need to be smart, only reliable
**in a testing environment, huge storage is not required
***However, install the OS on a small partition and leave the majority of the disk to be partitioned later
**in production this machine needs to have plenty of sata ports or some such
*in this case I am using another old dell dimension
*install debian testing (jessie)
*create the file /root/.ssh/authorized_keys and put your public ssh key in it.
*cp /etc/vim/vimrc /root/.vimrc
**edit /root/.vimrc and find the line 'set compatible'; uncomment it and change it to 'set nocompatible'
*edit /root/.bashrc, enable colours and any other personal preferences
*set apt repositories to contain contrib and non-free (optional, if needed for drivers)
*apt-get install ntp ssh
*apt-get remove rpcbind
*configure eth0 interface as 192.168.25.11

<h4>Switch</h4>
*for a one person test scenario, you can use a hub.
*scale up accordingly
*in this case, I am using a linksys wireless G unit flashed with openwrt.
**The wan port is taped over to prevent accidents. Always do this when you use wireless routers for switches.

==Plug It In==
*everything has a fixed ip, so test basic connectivity. make sure everybody can see everybody.

==Notes==
*dpkg --clear-avail<br>^^ This command fixes the "dpkg: warning: parsing file" errors
