Hi,

I have created juniper ned by using ncs netconf ned creation method, but after adding a new device using the same ned getting connection refused.

Package Reload Successful and also there is no error during compilation.

Did you get the host keys from the device?
Try doing "devices device Newnedrouter ssh fetch-host-keys", and then try connecting to the device.

Ping works because it is over ICMP, and does not need the host-keys. To connect over SSH, NSO needs the host-keys from the device (you can disable host-key verification if you want, but it is not recommended).

Or perhaps the netsim device is not running. That seems more in line with the error "connection refused".

Are you sure you started the netsim device?
