How to gain root access to the NLS AWS EC2 AMI?

Hello,
I am trying to evaluate Nagios Log Server, but I run into setup and configuration problems.
I followed "
How To Create A Nagios Log Server Instance In The Amazon EC2 Cloud Environment" instructions and used
EU-West version of the image. When I tried to SSH in the first time, I got the message:
Code: Select all
Please login as the user "cloud-user" rather than the user "root".
I was able to log in as cloud-user instead. I am also able to log in to Nagios Log Server web console.
The first time I needed root access when I wanted to fix system timezone. Right now, I need root access to install tcpdump to follow
debugging instructions, otherwise I can not proceed with the evaluation.
How can I gain root access?
Thanks in advance.

Does the command sudo su work?

I have tried sudo su before.
Code: Select all
sudo -i
[sudo] password for cloud-user:
Sorry, try again.
[sudo] password for cloud-user:
Sorry, try again.
[sudo] password for cloud-user:
Sorry, try again.
sudo: 3 incorrect password attempts
I have tried a bunch of default passwords that know of. What's the correct password?

There is no root password on AWS instances. Have you tried following the part in the directions where it says:
When connecting you must use the username ec2-user NOT root. This user has full sudo access.

I did not try to log in as ec2-user because I got the following output.
Code: Select all
ssh -i key.pem -v XX.XX.XX.XX
.....
debug1: Remote: Forced command: echo 'Please login as the user "cloud-user" rather than the user "root".';echo;sleep 10
.....
Permission denied (publickey,gssapi-keyex,gssapi-with-mic).
Logging in as cloud-user worked. This has lead me to think that
cloud-user is the updated name of ec2-user.
Logging in and gaining root access as ec2-user worked.
Thanks for the quick response!

The underlying base AWS EC2 instance always has an ec2-user for RHEL derived OS installs. Glad I could help.
