Hi,

Newbie here. I am using Ansible 1.3.2 on Ubuntu 13.04 and LXC. I have copied my SSH public key into the box’s ~/.ssh/authorized_keys and I can SSH passwordlessly on the command line. When I try Ansible commands I get SSH error:

~/mybox$ ansible-playbook -vvv -i hosts.txt site.yml

Could you run it with the -vvvv (4 v’s) as recommend and show the output?

Hi James,

Could you run it with the -vvvv (4 v’s) as recommend and show the output?

I ran it with 4 v’s and here’s the output:

~/mybox$ ansible-playbook -vvvv -i hosts.txt site.yml

So it looks like your hosts.txt file is not formatted properly, could you show that please?

So it looks like your hosts.txt file is not formatted properly, could you show that please?

The file content is verbatim below:

~/mybox$ cat hosts.txt
[hosts]
#10.0.3.181
10.0.3.188

[tomcat-servers]
hosts

Put the names of your tomcat servers under the group label
If you have two hosts named foo and bar it would look like this:

[tomcat-servers]
foo
bar

7

It should be:

[tomcat-servers:children]
…

to signify that the name is a group of groups.

Thanks James and Michael!
