Hi,

It’s apparently a common issue / misconception about running Ansible on JunOS. See: Understanding the Ansible for Junos OS Collections, Roles, and Modules | Ansible for Junos OS Developer Guide | Juniper Networks TechLibrary

Use junipernetworks.junos.junos_ping module or ansible.netcommon.net_ping module instead.

Hi,

Thanks for keeping me posted.
I tried to use the junipernetworks.junos.junos_ping module but still I get the error

My concern is why there is warning message showing SFTP while i am trying to do Ping and i created a play and try to execute it but it still throws the same error.

Hello @Saran307,

I don’t have much experience with juniper but I’ve read something around here about similar problems. Check this out:

Probably because Ansible is trying to copy the module over, as it’s not an ICMP ping but a script executing locally.

In addition to @jbericat answer, also ensure you are using network_cli connection plugin, as stated in documentation:

This module works only with connection network_cli.
