Hello Group,
New to Ansible and the Project, but like what I see so far!
I am running Ansible 2.4.0 on RHEL7.4. I have SSH keys setup on several
hosts and can connect to the remote hosts using the SSH Key Pair from my
Ansible Control node and not be prompted for passwords, all as the root
user in my POC.
The issue I am seeing is that even though I can use the SSH keys to
connect, Ansible is failing in anything but a "raw" connection. I am
guessing there is some oddity in my system or root shell profile (bash),
but I have tested working machines in my Lab to non-working machine in the
Dev environment.
The issue seems to be stringing commands together over the SSH connection.
I can see this issue when even running commands over SSH. But I know for
certain that the actual login process using the SSH keys does work. Below
is an example of the debug output when trying to run an ad-hoc command, I
tired to include what I thought was the most relevant info, but if more is
needed, please let me know!

To this appears to be making the SSH connection as the Banner is displayed,
but when Ansible tries to string a couple commands together, the second,
and subsequent, command fails, which is causing the play to fail.
I have tried comparing /etc/profile and any .profile/.bashrc files between
working and non-working nodes, but I must be missing something as I cannot
get the non-working nodes, to, well, work.
Below is a success using the 'raw' module for the same host:
# ansible broken-host -m raw -a 'uptime'
broken-host | SUCCESS | rc=0 >>
Shared connection to broken-host closed.
An SSH session, we do have root logins set to "forced-commands-only" so not
sure if this is an issue, I did test setting this to "yes" and restarting
SSH but still my Ansible commands fail:
# ssh -q broken-host "grep Root /etc/ssh/sshd_config"
PermitRootLogin forced-commands-only
I am just not sure where to go from here, any help would be greatly
appreciated!
Thanks,
-Mike
