I trigger the below ansible playbook using Jenkins pipeline.
- name: Play 2- Configure Source nodes
hosts: "{{ location }}"
user: remoteuser
strategy: free
gather_facts: false
vars:
ansible_ssh_extra_args: -o StrictHostKeyChecking=no -o ConnectionAttempts=5
ansible_ssh_private_key_file: /app/automation/id_rsa
tasks:
- name: Execute script
shell: "/app/mybkp.sh"
The above ansible-playbook is run as below in debug mode:
ansible-playbook orabackup.yml_final -i ora.hosts -f 90 -e location=MYIP -e
ansible_ssh_use_tty=no -vvv
Below is the output where the Jenkins freezes and never completes.

The ssh constructed by ansible as visible in Jenkins log above, when
executed manually in putty terminal also freezes / hangs and never returns.
This issue does not happen with other IPs but is specific to this IP
10.0.0.111
I removed '/bin/sh -c '"'"'/usr/bin/python3 && sleep 0'"'"'' from the ssh
command, tried manually and it worked !!
I have uploaded the working ssh without '/bin/sh -c '"'"'/usr/bin/python3
&& sleep 0'"'"'' in debug mode here:
https://drive.google.com/file/d/1MGWpWK2IeWa_LlifixrLTCwxv1IfvH2t/view?usp=sharing
I have uploaded the failed(freezing) ssh with '/bin/sh -c
'"'"'/usr/bin/python3 && sleep 0'"'"'' here:
https://drive.google.com/file/d/1yXictTMKfNDqu4wqQejyt5TVM483v7s2/view?usp=sharing
Further, even '/bin/sh' hangs when i try
ssh -o 'IdentityFile="/app/automation/id_rsa"' -o
KbdInteractiveAuthentication=no -o
PreferredAuthentications=gssapi-with-mic,gssapi-keyex,hostbased,publickey -o
PasswordAuthentication=no -o 'User="remoteuser"' -o ConnectTimeout=10 -o
StrictHostKeyChecking=no -o ConnectionAttempts=5 10.0.0.111 '/bin/sh'
The target server 10.0.0.111 is AiX 6.1.
Can you please suggest how do I resolve this issue?
