60 second vi intro

blog, Linux, Ubuntu
vi is neat.  Most of the engineers I work with like nano or pico but I like vi.  For some reason it makes me feel more like a geek when I'm using it.  In fact, I've been using it so often lately that I have been trying to use vi command in notepad (obviously without success).  This tutorial will cover only the basics but that should be enough to get you started.  A much better tutorial is available here. vi /etc/network/interfaces - opens /etc/network/interfaces in vi i - insert / - search G - [Shift] g - go to bottom of page dd - delete the line d <- or d -> - d [left or right arrow] delete 1 character in that direction 10G - 10 [Shift] g -…

Getting Ubuntu Ready for “REAL” use…

Linux, Ubuntu
I love Ubuntu...it's undubitably the best free OS on the planet. However, there is one thing that I absolutely hate about Ubuntu.. My inability to SSH into the system from anywhere. I know it is this way by design and that it's a "security" feature but it still annoys me. So the following commands are what I use to get the system ready for use after a fresh install. apt-get install openssh-server openssh-client That's it. If you want to play around a little more you can configure Ubuntu's firewall in just a few simple steps as well. In my example I will enable tcp/80, tcp/443, tcp/22 and udp/53 inbound. ufw disable ufw allow 80/tcp ufw allow 443/tcp ufw allow 22/tcp ufw allow udp/53 ufw enable And then you can validate…

Switchvox PBX replaced my trixbox

Linux
This was a pretty quick change but one of my friends recommended that I try out Switchvox which is an IP PBX build on Asterisk and is owned by Digium. I took a few looks at the webpage and I was pretty much sold. It looked so easy (and pretty). I installed it on a separate machine that I just picked up from a school district that was getting rid of PC's for dirt cheap from an old computer lab. The setup was almost the same as trixbox but had fewer questions for me to answer making it simpler overall. Once installed, the first thing that I noticed was the SSL based access to the box was the only way to manage the server. This was cool and questionable at…

trixbox now working

Linux
Well, a few weeks ago I really wanted to get a home phone setup for my house. My wife an I have been using our cell phones for pretty much everything for the last 2 years and thought it would be a good time to get something else. So instead of taking the easier route with a telephone company, I chose to setup Asterisk on an old extra computer with a Sipura SIP converter connected to a traditional home phone. My VoIP provider is TelIAX out of Colorado and so far has been pretty cheap. I would say the support isn't the best but as long as you know what you are doing, the system is always online. The real reason I chose them was their IAX2 support. I didn't…

Everyday Free Tools – Tech Stuff

blog, Linux, pfSense, Ubuntu
Each and every day I use a set of tools, mostly free or open source ones that help me get through the day. I though I would list of a few of them for you so that you can give them a shot as well. Home Computer I have a Panasonic Toughbook laptop running Ubuntu 7.04 that I really haven't modified too awful much because I like the look and feel of the OS as it is. Here's a list of things that I use everyday or every so often to accomplish a task without spending any money. Operating System - Ubuntu 7.04 - Stable, clean, easy to install, based on GNOME and very well supported by the community. I would say that the forums for Ubuntu are better than…
