Trying to install a AWS ec2 instance. Tried the following steps but unable to ssh to the instance or open the instance url in the browser.. kindl help me out. Thanks in advance.
Step1: Created a keypair
(prompt$) ec2-add-keypair ubuntuInstance10.4Keypair1
KEYPAIR ubuntuInstance10.4Keypair1 87:11:8f:c9:c5:53:14:6e:2a:92:07:20:03:7a:10:fb:7a:01:07:c3
-----BEGIN RSA PRIVATE KEY-----
<keypair code here>
-----END RSA PRIVATE KEY-----
Step2: Saved the above private key in a file (ubuntuInstance10.4Keypair1)
Step3: Changing the permissions of the private key
(prompt$) sudo chmod 600 ID_RSA_ubuntuInstance10.4Keypair1
Step4: Running the instance having the AMI as "ami-5ed62337"
(prompt$) ec2-run-instances ami-5ed62337 -t t1.micro -k ubuntuInstance10.4Keypair1
RESERVATION r-22efba4f 791715039698 default
INSTANCE i-aa558cc5 ami-5ed62337 pending ubuntuInstance10.4Keypair1 0 t1.micro 2011-03-27T15:12:51+0000 us-east-1d aki-754aa41c monitoring-disabled ebs
(prompt$) ec2-describe-instances
RESERVATION r-22efba4f 791715039698 default
INSTANCE i-aa558cc5 ami-5ed62337 ec2-67-202-5-28.compute-1.amazonaws.com ip-10-204-202-127.ec2.internal running ubuntuInstance10.4Keypair1 0t1.micro 2011-03-27T15:12:51+0000 us-east-1d aki-754aa41c monitoring-disabled 67.202.5.28 10.204.202.127 ebs
BLOCKDEVICE /dev/sda1 vol-296a5541 2011-03-27T15:13:08.000Z
Step5: Authorizing the port (this command failed)
(prompt$) ec2-authorize default -p 22
Client.InvalidPermission.Duplicate: The permission '0.0.0.0/0-1-22-22' has already been authorized on the specified group
Step6: SSHing to the instance (This command failed)
(prompt$) sudo ssh -i ID_RSA_ubuntuInstance10.4Keypair1 root@ec2-67-202-5-28.compute-1.amazonaws.comip-10-204-202-127.ec2.internal
ssh: Could not resolve hostname ec2-67-202-5-28.compute-1.amazonaws.comip-10-204-202-127.ec2.internal: Name or service not known
Also tried to open the instance(ami-5ed62337) in browser as http://ec2-67-202-5-28.compute-1.amazonaws.comip-10-204-202-127.ec2.internal
this resulted in the following messages
"Oops! Google Chrome could not find ec2-67-202-5-28.compute-1.amazonaws.comip-10-204-202-127.ec2.internal"
