Hosting at home...

Some notes i captured while i was experimenting hosting my website at home.

Setting up hosting on your home computer
source: http://www.boutell.com/newfaq/creating/hostmyown.html

Free DNS Hosting:
There are many options, i went with ZoneEdit.com

- Sign up for ZoneEdit.com (also check out dyndns - not free tho)
- Add Zones
- Provide your zone (domain you want to use)
- Provide the ip address - your current home ip address
- Copy the nameserver addresses
- Contact your registrar (example: www.godaddy.com) and tell them to change the nameservers for your domain, or use these nameservers when you buy a new domain.
- You can do this on your own.
- log into godaddy
- domain manager
- manage domain
- update nameservers


Getting Apache server on your linux
source: https://help.ubuntu.com/6.06/ubuntu/serverguide/C/httpd.html

sudo apt-get install apache2
- configurations : /etc/apache2/apache2.conf
- The default page is taken from /var/www/

sudo /etc/init.d/apache2 start

Setting up dynamic DNS on your home computer
Why? Cause your home computer IP will keep changing each time to login to the network
- I'm using http://sourceforge.net/apps/trac/ddclient
- check out the code

svn co https://ddclient.svn.sourceforge.net/svnroot/ddclient/trunk ddclient

- go through the README file once downloaded
- follow the steps
- to start
/etc/init.d/ddclient start

/usr/sbin# ddclient -daemon=0 -noquiet -debug -ip=71.198.38.193


Getting your home router to give you a static IP
- log into netgear (or your router)
- Attached Devices (see whats attached already)
- Lan IP Setup
- Address reservation
- Provide the IP and the devices mac address and you're all set.

Notes:
- To check your current IP I used http://www.ipchicken.com/

Smart Grid IPOs and Trilliant...


Here's an excerpt about the company i work for...:

Enter Trilliant, a prime candidate for a 2010 smart grid initial public offering (IPO).
The company makes wireless devices that attach to existing meters and devices at each tier of the electricity distribution system, allowing for the real-time relay of information about substations, outages, and the energy usage patterns of neighborhoods and schools.
For the tech savvy out there, Trilliant's products are better than their competitors because they support multiple modes of data transfer, including static IP, dynamic IP, and circuit-switched.
What's more, the company is in bed with the big boys. Their products are compatible with a number of branded meters, including models from GE, Landis+Gyr, and Obama's darling, Itron.
Consumers can even get the data on their cell phones. Trilliant's feed is compatible with Verizon, Sprint, AT&T, Telus, Rogers, and a number of other wireless service providers.
And Trilliant is allowing things to be done in the electricity industry that have never been done before...
  • Real-time pricing based on usage profiles of homes and neighborhoods
  • Remote connect/disconnect
  • Voltage reporting
  • Automated power outage reporting
Further down the line, Trilliant's systems will be used to optimize energy efficiency, enable demand response, help integrate distributed sources like wind and solar, and help with the adoption of charge-at-home vehicles.
What we're about to witness is the networking of the grid — the Internet for energy.
This was the aim of the $3.4 billion: to bring smart grid solutions to the table.
