Connecting to Amazon Virtual Private Cloud using Linux

Hello internet,

I am trying to connect my Linux machine to Amazon VPC using end to end IPSec tunnel. I have set all the required VPC objects on Amazon side and now plan to set my Linux Laptop as a VPN gateway. But the only doubt I have is that my Laptop is behind NAT. Though I have opened and re-directed the necessary ports on my NAT device I am not sure if this thing is going to work.

Please let me know if this setup can work. I am trying to follow the following guide

http://openfoo.org/blog/amazon_vpc_with_linux.html

From what I understand so far in order to make this guide work for my setup I need to do some extra configuration. I have also found out that IPSec supports tunnels behind NAT devices but I am not sure if Amazon VPC will support such configuration.

Any help in this matter is highly appreciated.

Using Boxgrinder to build your own AMI for EC2

In my last article I showed on how to create your own AMI for EC2. The article basically demonstrated the whole process been done manually by executing commands. In this article I would like to cover Boxgrinder which reduces the manual effort completely and helps you get your own AMI registered on EC2 and in few minutes.

First thing is that we need to run boxgrinder on CentOS if we would like to build a CentOS AMI and on Fedora if we would like to build a Fedora AMI. The good thing about boxgrinder is that it uses the latest pvgrub kernel images provided by Amazon which basically lets you boot into your own kernel. So gone are the days when we had to use Amazon EC2 kernel. Thanks to Marek Goldmann for making this possible in boxgrinder 0.5

Creating your own AMI for Amazon EC2

It’s been long since I posted on this blog. This time I have come up with this new post which takes you through on how to go about creating your own Amazon Machine Image (AMI) for Amazon EC2. Note that there are several publicly available AMI’s on Amazon which one can use for various purposes but sometimes we require to have a AMI of our own which has all the require software / configuration to meet our daily requirements. That is time we need to know how to create our own AMI.

I would like to thank Phil Chen for his excellent post here http://www.philchen.com/2009/02/14/how-to-create-an-amazon-elastic-compute-cloud-ec2-machine-image-ami which I followed and have mentioned below with some extra addition and some modification.

Fedora 13 release party in Bangalore

I am a little late on writing about the release party we had last week on Saturday, was occupied with $work.  Well it all started with the mail of Rangeen to FSUG mailing list. That time I have just come to Bangalore and thought it will be great to meet all the Fedora folks in Bangalore during such party. Venue was a big issue initially as almost all the colleges in Bangalore were having exams. But I knew my friend Saket who has been pretty active in FSMK Bangalore. I contacted him and asked him if we can organize this release party at FSMK Bangalore office. I got a positive reply and after confirmation from the FSMK folks we finalized to have it at FSMK Bangalore office on June 5th.

I personally never expected many folks to turn up because of two reasons. One been that many colleges in Bangalore were having end semester exams plus we don’t have much Fedora folks here in Bangalore. Initially we (Me, Ankur, Hiemanshu , Dipjyoti and Rangeen) had a hard time finding out the office. Point to remember GPS in India will not be accurate enough with all these narrow lanes everywhere.

Cloud Computing is the future

Well for those who don’t know, since Jan 2010 I have been working on eucalyptus a open source software to setup private cloud inside organization premises.

I have seen lot of people blogging about eucalyptus specifically on Ubuntu Server edition. Well to be frank eucalyptus is a great software and it works with almost al latest linux distributions. Though I haven’t found time to test all the available linux distribution as I am stuck with work and Fedora but I have tested it on centos 5.4 and Fedora 12. Works great!

Few problems I have always faced but the IRC channel for eucalyptus on freenode as well as the online forums have been really helpful in solving my doubts.

I plan to write my experiences with eucalyptus on this blog in times to come. Besides eucalyptus creating virtual appliances in a automated way is also one of the areas I have worked on paste few weeks. This is all specific to fedora right now using boxgrinder. It is a alternative to vm-builder which ubuntu folks have got.

I am a strong support of the fedora project and love the way how the fedora community is structured and functions. Have been associated with it since the beginning (Fedora core 1).

In the end, for now, I would just like to say, cloud computing is the future and open source is the best medium we have all got to implement it.
