Delete SSL certificates from Amazon IAM account

gnufreakz — Wed, 16 Nov 2011 14:03:25 +0000

Each account in the amazon has a limitation to hold 10 SSL certs and if you exceed this value, you wont be able to upload/attach any more SSL certificates to the load balancers (ELB’S). It will throw an quota exceed error.

You cannot delete amazon SSL certificates through GUI. Amazon API tools is required for this task.

Download the IAMCli utilities from amazon and untar it in /root

export AWS_IAM_HOME=/root/IAMCli-1.2.0/

List the available SSL certificates in the account

# /root/IAMCli-1.2.0/bin/iam-servercertlistbypath –aws-credential-file /root/my-account-creds.txt
arn:aws:iam::609154335954:server-certificate/answerable-com-lb-ssl-cert
arn:aws:iam::609154335954:server-certificate/cdn-olokiran-certif
arn:aws:iam::609154335954:server-certificate/cert
arn:aws:iam::609154335954:server-certificate/dsp-olokiran-com-cert
arn:aws:iam::609154335954:server-certificate/ostk-kik

Delete the unwanted certificate using the following command

/root/IAMCli-1.2.0/bin/iam-servercertdel –aws-credential-file my-account-creds.txt -s dsp-olokiran-com-cert

where

# cat /root/my-account-creds.txt
AWSAccessKeyId=XXXXXXXXX
AWSSecretKey=xxxxxxxxxxxxxxxxxxxxxx

Using the same tools you can even attach SSL certificates to the ELB’s.

Share EC2 instances among multiple load balancers

gnufreakz — Wed, 16 Nov 2011 13:13:15 +0000

Download amazon Elastic load balancer API tools

export the home:-

export AWS_ELB_HOME=/root/ElasticLoadBalancing-1.0.14.3/

Add your credentials in /root/my-account-creds.txt

# cat /root/my-account-creds.txt
AWSAccessKeyId=XXXXXXXXX
AWSSecretKey=xxxxxxxxxxxxxxxxxxxxxx

Suppose kiranchand.com is the name of loadbalancer you have created. In this way you can share a set of EC2 instances across different load balancers.

# /root/ElasticLoadBalancing-1.0.14.3/bin/elb-register-instances-with-lb kiranchand-com –instances i-e4515989,i-fedad293,i-4974fc27,i-70c6ed10 –aws-credential-file /root/my-account-creds.txt
INSTANCE_ID i-e4515989
INSTANCE_ID i-fedad293
INSTANCE_ID i-4974fc27
INSTANCE_ID i-70c6ed10

How to create an AMI backup out of EC2 instance

gnufreakz — Wed, 16 Nov 2011 12:49:16 +0000

Create the bundle of the Operating system. You should avoid big disks like EBS while creating the bundle

ec2-bundle-vol –cert /root/key/cert-XXXXXX.pem –privatekey /root/key/pk-XXXXXX.pem -d /mnt -e /ebs –user 4091-5433-5954 -r x86_64 –debug

-e = exclude

-d=destination where file has to be created.

Upload the bundlie:-

ec2-upload-bundle -b Server-backup-$MONTH –manifest /mnt/image.manifest.xml –access-key XXXXXXX –secret-key bKxxxxxxxxxxxxxx

ec2-register “Server-backup-$MONTH/image.manifest.xml” -C /root/key/cert-XXXXXXXX.pem -K pk-xxxxxxxxx.pem Server

Thats it !!… You can find the AMI in amazon aws console. If you want to create a new instance out of it, right click AMI -> create new instance and follow the instructions.

Scrummworks admin password reset

gnufreakz — Mon, 04 Jul 2011 11:39:16 +0000

To reset your administrator password do the following:

1) Shutdown ScrumWorks Basic, if it is running.
2) Navigate to your ScrumWorks install directory.
3) Go to ‘server/scrumworks/data/hypersonic’
4)Open the scrumworks.script file and search for ‘administrator’, the first result should be your admin user account.

There will be a value with the current password in front of it. Remove that value and the current password text and replace it with the plaintext password you want for your administrator.

You can now login as administrator and change other users’ passwords.

Nagios installation and SMS alert using clickatell

gnufreakz — Thu, 17 Mar 2011 06:45:48 +0000

Installing nagios:-

I used this script for installing nagios

================================================================

#!/bin/sh

# Any Failing Command Will Cause The Script To Stop
set -e

# Treat Unset Variables As Errors
set -u

echo “***** Starting Nagios Quick-Install: ” `date`
echo “***** Installing pre-requisites”
yum -y install httpd
yum -y install gcc
yum -y install glibc glibc-common
yum -y install gd gd-devel

echo “***** Setting up the environment”
useradd -m nagios
echo “bharathi” |passwd –stdin nagios
groupadd nagcmd
usermod -a -G nagcmd nagios
usermod -a -G nagcmd apache

echo “***** Getting the Nagios Source and Plug-Ins”
cd /usr/local/src
wget http://prdownloads.sourceforge.net/sourceforge/nagios/nagios-3.2.0.tar.gz
wget http://prdownloads.sourceforge.net/sourceforge/nagiosplug/nagios-plugins-1.4.14.tar.gz
tar xzf nagios-3.2.0.tar.gz
tar xzf nagios-plugins-1.4.14.tar.gz

echo “***** Installing Nagios”
cd /usr/local/src/nagios-3.2.0
./configure –with-command-group=nagcmd
make all
make install
make install-init
make install-config
make install-commandmode
make install-webconf

echo “***** Setting up htpasswd auth”
htpasswd -nb nagiosadmin bharathi > /usr/local/nagios/etc/htpasswd.users
service httpd restart

echo “***** Setting up Nagios Plug-Ins”
cd /usr/local/src/nagios-plugins-1.4.13
./configure –with-nagios-user=nagios –with-nagios-group=nagios
make
make install

echo “***** Fixing SELinux”
chcon -R -t httpd_sys_content_t /usr/local/nagios/sbin/
chcon -R -t httpd_sys_content_t /usr/local/nagios/share/

echo “***** Starting Nagios”
chkconfig –add nagios
chkconfig nagios on
service nagios start

echo “***** Done: ” `date`

=====================================================================

After executing the above script you can get the nagios installed in /usr/local/nagios/. Check the localhost.cfg file and you can get the remote host configuration. What I did is I created a domain template file having the file

I had a hell out of time for the configuration of nagios and clickatell SMS gateway configuration…Finally I made it…:)

You can get the latest template based configuration from the URL

Apple TV review (2010)

By Joshua Topolsky posted Sep 29th 2010 12:55PM

Review

You’ve been waiting, and it’s finally here: the Apple TV review. Months before Steve Jobs announced the new set top box at Apple’s annual fall event, we had been reporting on news that the company would strike out again into the TV market, offering a small, low-cost box that had more in common with the iPhone than the iMac. When those rumors came to fruition, we were presented with the completely revamped Apple TV — a tiny black puck of a device priced at a staggering $99, and centered around a handful of completely new ideas (for the folks in Cupertino at least) about getting content onto your TV screen.

Playstation Phone !!!

gnufreakz — Wed, 27 Oct 2010 06:25:49 +0000

It’s hard to believe that what we’re looking at is real — but we assure you, the picture above is in fact the PlayStation Phone you’ve long been waiting for. As we reported back in August, the device you see is headed into the market soon, likely boasting Android 3.0 (aka Gingerbread), along with a custom Sony Marketplace which will allow you to purchase and download games designed for the new platform. The device snapped up top (and in our gallery below) is sporting a 1GHz Qualcomm MSM8655 (a chip similar to the one found in the G2, but 200MHz faster), 512MB of RAM, 1GB of ROM, and the screen is in the range of 3.7 to 4.1 inches.
