Why do we have the right to condemn the person that WAS VOTED INTO OFFICE TO DEATH because of his race/politics/choices? As Americans we have the right to vote him out of office, that it IT. THOU SHALT NOT KILL or have you forgotten your studies? Any responsible citizen should dispute the comments involving the death of the president, it was not put up with in the days of your parents, it should not be put up with now. They respected their elders, but they also had to make hard decisions, we do too, don’t give up on your point of view because your elders don’t respect the president. They should be citizens too, even if they don’t agree with him.

Encrypt it. Yes I know you have all heard this about a million times, but it is the first and best way to protect your privacy and long term sanity. Wireless antennas broadcast information in a 360 degree pattern from the base station, then means that when your wifi is near your neighbor’s window, he has just as good reception as you do. Encrypt access to your wireless, starting with a MAC block is a start, it would be best to also use WPA2 encryption as it has been proven that WEP encryption takes about 45 seconds to crack if you know the right tools. If you allow customers to acces your wifi, passwords and MAC addition can make using your wifi more trouble than it is worth. For these types of networks, I suggest obtaining a router or AP that offers wireless client isolation, this at least will prevent a wifi user on your network from easily attacking another user. Also, make sure that the business network is separate from the customer wifi, as this could give your customers access to all the business financial documents. When I say seperate, I mean behind a firewall that does not allow any access between the two.

Use a better router. I have found that an old computer with a P3 or comparable processor can be made into a very powerful router. Free software like PfSense, IPCop, or Clarkconnect, are designed to act as a firewall/router/server geared toward the professional or hobbyist that is willing to learn a little about what makes a good service. Computer based routers make things a lot more controllable because you can add software to meet your needs, and offer stateful packet inspection (SPI). Another advantage is the firewall configuration options, I use PfSense and have more options than I can think of using.

Block certain services. One of the more useful services that good routers provide is port blocking, I know that some of the better linksys routers offer the same service, but I have found that if you have more than about 5 people using it at once, it can overwhelm the router and leave it ‘bricked’. I block ports 6667-6999 because these are the standard bittorrent ports, while I have no personal issue with bittorrent, I have a legal problem with getting sued over a customer downloading music illegally. Also, someone using your wifi for bittorrent will end up bogging down your surfing as well as put you at risk. I also block 53 with the exception of the openDNS servers so users can’t easily bypass my content filtering. Which brings up our next subject.

Use a DNS server that offers content filtering. The reason for this is twofold, it provides you with details about what services your users are surfing, which might affect advertising, and it prevents unwanted activity from affecting your network or your users. I use a free service provided by openDNS.com that gives me a choice of 50 different block options and allows me to blacklist or whitelist sites as I see fit. An infected computer behind a firewall makes the firewall pretty much useless as the infected computer is already past the firewall, a malicious program accidentally found on an unsavory website can be the cause, so rather than wait until it is too late, I try to prevent my users from visiting sites that could be a potential risk.

There is no real way to make the internet safe and completely accessible, it is a constant balance between accessibility and security, one that never seems balanced to everyone. As long as the steps you take are reasonable, they are steps that you can defend when you do have a grumpy user, very few of us get it right the first time.

Example: Social Security.
Example: Welfare.
Example: Medicare.

Anyone who takes part in these programs benefits from government spending on its own people. So I ask, who out there who partakes in these programs voluntarily thinks that socialized medicine is a bad idea? In the long run it will lower medicare costs, reduce employee downtime, and make a more rugged society in general. Social security, Medicare, and Welfare are no less “socialist” than programs America has in place today. I urge any persons who are serious about denying social medicine a chance, to look at the programs they take advantage of and ask themselves why it is fundamentally different. If you still think it is wrong, stop signing that welfare or social security check, and stop letting medicare cover your medicine.

The jeep is unhappy. It has a leaking rear axle seal, a loose mounting between the springs and the axle, and three out of four tires. Time to spend a money and love in fixing it up. I have some spare tires that should work, but I ended up getting an aftermarket cover for the axle. I will be putting shims in place to reduce the driveline angle and make the axle more secure.

The trixbox server is now hooked up to line two, we shall see if it is reliable enough to cancel the other phone line. I am thinking that I will also be looking into time based answers, like when there is nobody at the office, we can have an automated answering system.

The suzuki cold air intake has been installed. I have not seen any sort of milage increase since installation, but it does have more low end torque. I want to spend time this spring break installing sheet metal on the undercarriage of the car. This is to reduce drag at higher speeds. Hopefully, it will increase milage and performance. The concern is proper cooling, if the transmission has the same temperature after the drag reducing additions, it will be a good thing.

What you are going to need:
A spare computer to act as the VOIP server with an ethernet port.
Minimal knowledge of linux command line, remember, when in doubt, google
trixbox 2.4, we will be going over how to get the trixbox 2.4 software.
Access to your router and internet device, namely the ability to open incoming ports.

The first thing we are going to do is download trixbox 2.4, this step is less trivial than one would think, but has been made easy by the availibility of the .iso on this site. The trixbox site only hosts the latest version (2.6 at the time of this writing) which gave me a lot of bugs upon first install.

Download the iso from either this site or another site.

Install trixbox 2.4 on the server, the details of this step are outside the scope of this writing. But can be found on the trixbox website.

Once installed, the trixbox server will be set to an automatic address on your local network, the issue with this is that getting to the web interface is more difficult. If you have a IP scanner on your computer, use it to find the IP of the trixbox server. If you still cannot find the IP, I suggest googling the commands for looking up the IP address directly from the server.

Now that we have found the ip address of the server, use your favorite web browser to access the server. Type the ip address of the server directly into the browser address. (i.e. http://192.168.1.25)

The web interface will give you a screen that has a link in the upper right corner called “switch”, click this and you will be prompted for a username and password. The username is ‘maint’ and the password is ‘password’. Enter these values and click OK. You should change these to prevent hacking.

Close the registration window. You are now logged in as the administrator, look for a link called ‘Asterisk’ and click on ‘FreePBX’.

This will take you to the FreePBX administaration screen. Here we can create the user accounts/extentions and configure the SIP Truck which handles calls to the outside world.

We will first start by setting up an extention in FreePBX. Click extensions, then click submit. This will set up a new SIP extension, which is what your computer will use to connect to the trixbox server. Give the first user an extension number (201 works good) to start, this is the number you use to dial this user internally. Next select give the account a display name and a password in the ’secret’ field. For a basic extention this is all we need so click submit. Add at least one more for interoffice testing.

We now have the server set up for basic interoffice communication. Time to set up some user computers.

download X-lite from http://www.counterpath.net/X-Lite-Download.html , Install it, run it. Under SIP account settings, add a new account. In the account properties, create a display name, this will be the name that will show up on caller ID. The username will be your extension, the password will be the value you entered for ’secret’ and the domain will be the IP address of the trixbox server. click the register with domain and receive incoming calls checkbox and select domian. then click OK.

If you have done everything correct, Xlite should discover the network and prompt you saying ready and listing your extension. You can now make calls to and from extensions on the local network. Try dialing another extension you have set up and see how it works.

Next step is to add the ability to call outside your local network, this includes dialing out, and with the right customer plan, dialing in. So far we have not actually signed up for any service, all we have done is install server software and played with it to allow dave in accounting to talk to jill in marketing using their computers.

We need to get a service provider for incoming/outgoing. This tutorial will be using voicepulse so from here on all SIP trunking will be related to setting up service with voicepulse. If you do not like them, have a great time on your own. I spent two weeks stuck using vitelity and hated them. So I use voicepulse.

First, we need to sign up for an account with VP. Go to https://www-business.voicepulse.com/Secure/SignUp/SignUpWizard.aspx?sp=trial , use Trixbox CE as your PBX. Set up an account, they will give you information on how to download the voicepulse module.

Once you have downloaded the voicepulse module, get back into FreePBX, then click Tools, then Module Admin. Next click Upload module. Next find the file you downloaded and select it to be installed.

Once installed, enable the module. Once enabled, a voicepulse menu should show up in the left hand menu when you click setup. Start by clicking status, this should give you a basic idea of what they are doing for you. Next click troubleshooting and find what is and is not working. There should be at least one thing not working.

When I installed my trixbox, it said I needed to install the curl library. To do this, you need to login using SSH to the server. once logged in, follow the directions given to you by the module. (i.e. ‘yum install curl….’)

once this was installed. It all ran smoothly. I was able to make calls. This meant anywhere in the world as long as I was willing to pay. I did add the ability to block 411 calls and a dummy least cost routing mechanism. Otherwise, that is about it.

example:
Display Name: John Smith
User Name: 2xx (this value will be your extension)
Password: xxxxxxxx (supplied by provider)
Authorization user name: (leave this field blank)
Domain: example.com
OR
Domain: xx.xx.xx.xx (use this if you are on the outside of the network)

7.Click the “Register with domain and receive incoming calls”
8.Make sure domain is selected and click apply.

If properly configured, the unit should now be set up.

I found a way to put Win XP on my desktop, I am using nLite to do so. The issues stems from the ability to install XP on a computer using SATA, a standard not supported by the original version. nLite solves this by allowing drivers to be installed while the instal utility is being loaded, very cool.

I am playing with VoIP, Trixbox, Asterisk, Digium, and FreePBX right now. I actually found a way to connect my office and my apartment to the same phone network, so now I call the office using an extension, NO PHONE BILL! It is pretty cool. It also means that I can get rid of our Qwest phone lines in favor of VoIP, it is way cheaper and there is less issues, I am looking at saving about $100 a month in phone bills by switching.

The important one in this argument:
2 c: a cause of anxiety

By this definition Obama IS a terrorist! Want to know why? Sarah Palin roused her Ohio convention crowd so much they shouted “Terrorist!” And “Kill him!” Would that make you anxious?

Obviously this Obama character makes them anxious. I would argue that Palin is a terrorist by the same definition. She was there to bring up the issue and make them anxious about him. I would also like to cite Andy Martin as a Terrorist for being the first person to claim that Obama is a terrorist.

Do not forget that by bringing this to your attention it technically makes me a terrorist too, so don’t listen to anything I say.

TA!

P.S. McCain is a terrorist too because the idea of him kicking the bucket in office and Palin being president makes me REALLY anxious.
