Ansible | Some issues

In this post I want to share with you some problems that I was facing and that I managed to fix by searching on Google, making debugs and talking with friends.

#1) Problem to connect to devices using playbook:

fatal: [XXX]: UNREACHABLE! => {
    "changed": false,
    "msg": "Failed to create temporary directory.In some cases, you may have been able to authenticate and did not have permissions on the target directory. Consider changing the remote tmp path in ansible.cfg to a path rooted in \"/tmp\", for more error information use -vvv. 
    "unreachable": true
}

Workaround: type those commands into your ansible:

mv /usr/bin/sleep /usr/bin/sleep.dist
ln -s /bin/true /usr/bin/sleep

#2) Problem to connect to devices with crypto:

"msg": "p must be exactly 1024, 2048, or 3072 bits long"

Workaround: Try this commands below:

ssh -o HostKeyAlgorithms=ssh-dss -c aes256-cbc login@ip-address

Inside the host file, insert:

ansible_ssh_common_args="-o HostKeyAlgorithms=ssh-dss -c aes256-cbc"

Make sure your router is using the same encryption as you are sending!

#3) Problem with ssh service:

root@DRM:/etc/ansible# service ssh status
 * sshd is not running

Workaround: Try to restart the process.

root@DRM:/etc/ansible# sudo service ssh start
 * Starting OpenBSD Secure Shell server sshd   
 [ OK ]

root@DRM:/etc/ansible# service ssh status
 * sshd is running

---

#4) Packages and commands to installation and complete operation of Ansible:
