Public DMVPN network.

Saturday, October 3rd, 2009

I was thinking about a new project idea. I was thinking of setting up a dynamic multipoint VPN concentrator. Put a small LAN behind it with a couple of servers. Put the configuration instructions on a webpage for Juniper and Cisco devices. I was thinking to run BGP routing protocol over the interface as it scales reasonably well.

The important part here is I wanted to create a web form which requests the internal and external address ranges of anyones network. Once that person submits that information I will have a Peal script pull those messages from the web form, parse the information, insert the networks and IP addresses into a J-Script template and apply it to my Juniper SRX router automatically.

This project will enable Cisco and Juniper students to participate in the environment and create a public VPN network where p2p APPS and anything else can run over the network without having to worry about any prying eyes. I want to see how far this project will scale. I was even envisioning a time when other people with idle equipment can volunteer to become a secondary hub to take some of the load once my connection reaches 10 thousand or so tunnels. Because of the way DMVPN works. The tunnels between sites will open up as needed when a user from site A needs to talk to site B. This combined with using BGP as the routing protocol will mean that it will require very little bandwidth as traffic destined from site A to C will not transit site B if site B in this scenario is the hub.

Anyways if anyone out there is interested please leave a comment.

Send me questions and feedback!

I see a lot of you out there find this site through various search engines and many of you are searching for information on gre tunnels. I just wanted to say how much I appreciate the traffic and I want to let everyone know that creating an account is free and I would love to hear your feedback on articles and any questions you might have.

New TechCast Posted

I have been busy lately, I am in the middle of a Data Center migration at work, which is eating up hours of my personal time, and I have a million other projects on the burner. I have fresh content coming but in the mean time, I did a TechCast on Junos, please view the video at http://www.exiletv.com.

We have added a new forums section to techinvasion.net. We hope these forums will become a big part of the site and allow all the users to participate, ask questions, and get answers. The link to the forums is along the left hand side of the page in the categories section. You can also go directly to the forums by going to http://www.techinvasion.net/forum.

We are also looking for writers to post relevant articles such as the ones that have been posted by our 3 writers so far. If you are interested in writing for techinvasion.net please send an email to admin@techinvasion.net.  

MIT student arrested for fake bomb

Saturday, September 22nd, 2007

An MIT student was arrested in Logan intl Airport for wearing a sweatshirt with a prototyping board on it and a 9 volt battery which lit up some led’s that said MIT course VI which is the numerical designation for computer and electrical engineering majors. The shirt which she has and has been wearing for a long time, was something that a class of students made as a project. The police surrounded her in the airport with automatic weapons and arrested her, then commented that she was lucky to be alive. As you can see from the link to the article below anyone who has half a brain can see that it is a piece of techno art. However I just wanted to post this to solicit your opinions about the fear of electronics in this country and the sad state of affairs. This is even worse considering that MIT is known for its research in embedded computers in clothing and the airport is right around the corner from MIT! Also she walked up to the airline desk and asked when a flight was coming in because she was picking up a friend. She did not even try to get through the security checkpoint.

Open Solaris 10 sandbox

Monday, July 2nd, 2007

Thanks to those friendly people from Digg.com who decided it would be fun to bring my Solaris box to its knees by forking and other things to DDOS my Solaris zone. I have learned many ways of enhancing the security of Solaris zones. I have limited the Sandbox zone to 1% of total CPU usage. I have limited the total number of processes to 1000 and I have installed the Solaris Jass security hardening script. I plan to post many of my discoveries in the future. Work has been busy lately and it is on the burner of things to be done along with part 2 of solaris zones.

First Production ZFS server today

Monday, July 2nd, 2007

I have plenty of small business clients and sooner or later they all face one big challenge. They all outgrow the initial 80GB tape drives that we put on their servers. The problem is that most of these are small businesses and most of them could just afford the initial network, and asking them to pony up $2000+ for a new tape drive or worse yet autoloader is out of the question.

TV Networks Just Don’t Get it

Monday, July 2nd, 2007

I t seems to me that the big four tv network either don’t understand what people want or simply don’t care. If you look at the cable networks you have stimulating things to watch like Nip Tuck, Dexter, Sleeper Cell, Battlestar Galactica, Monk, and too many other good dramas to mention. However when you turn to the major networks they simply show one copied worn out reality show after another.

Until recently I assumed they just didn’t get it, but then I found out that it cost the networks on average 4 to 8 times as much money to produce a script based show. Kind of makes you think doesn’t it?
