When we want to connect to amazon server instance through linux terminal then you need to install the ec2-api-tools in your linux box. For installing the ec2-api-tools in linux box follow the steps.
You will find the rpm package in following URL:
http://www.rpmfind.net/linux/rpm2html/search.php?query=ec2-api-tools&submit=Search+…&system=&arch=
Use following commands for installing the api-tools.
[root@localhost www]# cd /tmp/
[root@localhost tmp]# wget ftp://195.220.108.108/linux/rpmfusion/nonfree/fedora/releases/12/Everything/i386/os/ec2-api-tools-1.3.36506-1.fc12.noarch.rpm
After this when I started to connect my amazon server instance then I got following error message.
Permissions 0755 for ‘ec2-project.pem’ are too open.
It is recommended that your private key files are NOT accessible by others.
This private key will be ignored.
bad permissions: ignore key: ec2-project.pem
For solving the issue you need to change the key file permission to 700. For that use following command
[root@localhost EC2key]$ chmod 700 -R ec2-project.pem
[root@localhost EC2key]$ ssh -i ec2-project.pem root@ec2-59-16-79-85.compute-1.amazonaws.com
