Hi list,
I'm having a problem with some of of my instances. I'm receiving the
following error when trying to do an apt-get install: Could not resolve '
us.ec2.archive.ubuntu.com'
Any ideas on how to solve this?
TIA

Re: unable to SSH after vmbuilder-created instance launches

Nate:
I've posted working samples of using vmbuilder to build EC2 AMIs here:

You could compare this to what you're doing to figure out where things
might be going wrong.

Thanks, Scott. I wrote up samples of steps to create an EBS boot AMI by
downloading the Karmic images you build instead of using vmbuilder:
[link]
I don't think this process is trivial yet for the average user and would
still love to see official EBS boot AMIs.

Re: [ec2ubuntu] Auto Terminate Instance: Possible or Not?

simon.l...@gmail.com (Simon Lord) — Fri, 08 Jan 2010 08:44:47 UT

You can invoke the linux shutdown command
([link]) to terminate instances.
If your running instances have access to your aws credentials then you
could prgramatically terminate the instance via AWS
terminate-instances method

Is it possible to have a node terminate itself?

.....and in what appears to be a clear cut case of pebkac... the
server version doesn't have the tools installed that the base version
does...
hence the script fails since the tools aren't in the right place or
any place at all. The 9.10 karmic server version from aws doesn't
even have ami tools installed as base... and attempts to install them

I've gone back and checked some of my earlier posts on experts
exchange.
I've installed CPAN, perl as well, and the script is not functioning
as per planned.
I am trying to set it up so that after significant changes are made to
a server it can be bundled then uploaded so we have a running
progression of backukps as the server config goes through it's various

hrm, nope that wasn't the cause. I copied the script from my social
text page that did not have the "-" before the x on that page, but the
script does have it. A pathing issue perhaps since I noticed the
normal ec2 directory is not in /etc/ in 9.10

I've been working this week on ec2init for lucid, and it will/does
transparently support gzipped user data.

Oh,. the smallest errors are always the hardest to spot. Thank you
very very much.
I am actually trying to do both, well for some of the servers
anyways. Our DB servers I have an autosnapshot script that I've found
that backs up our db, every 4 hours courtesy of crontab
But I do want the auto bundle feature to work as well since some of my

An update. My snapshot script now stores these values in the
snapshot description. Afterwards I can run another script:
snapclone snap-01010101
The snapclone script extracts the values from the description and
runs a cloned ebs-backed instance after first registering the
image (which is optionally deregistered after the instance is

Kernel Updates?

ja...@jamesward.org (James Ward) — Thu, 07 Jan 2010 15:27:01 UT

Hi,
Newbie question... Today apticron told me that I have a kernel update:
linux-image-2.6.31-17-virtual 2.6.31-17.54
linux-image-virtual 2.6.31.17.30
linux-virtual 2.6.31.17.30
Could updating these packages without actually updating the kernel
referenced by my EC2 instance break anything? And suppose that these

Re: [ec2ubuntu] Supporting gzip-compressed user data

ehamm...@thinksome.com (Eric Hammond) — Thu, 07 Jan 2010 10:29:00 UT

Thanks, Tom.
I committed the patch to revision control and it will go in the next release of the AMIs.
If you really need this feature going forward, you'll want to convince the ec2-init package maintainers (Ubuntu server team) to incorporate it in their startup code.

Re: [ec2ubuntu] mkswap on ephemeral block device at boot?

) What's the problem on 64-bit?
Amazon chose not to enable swap by default on the 64-bit instances. I don't know why.
I prefer no swap for my servers all around.
) Mine are registered simply as
)/dev/sdb=ephemeral0,/dev/sdc= ephemeral1
Looks ok to me.

Supporting gzip-compressed user data

tom.e.wh...@gmail.com (Tom White) — Wed, 06 Jan 2010 21:30:11 UT

For our Hadoop AMIs ([link]
_getting_started.html) we've been using a slightly modified version of
ec2-run-user-data ([link]
init.d/ec2-run-user-data) which will check if the user data is gzip-
compressed, and decompress it before running it. This is a useful way
