This one has me scratching my head....

Trying to connect to an EX-3400 using PyEz. I've done 'set system services netconf ssh'. I can connect fine using ncclient but PyEz gives me "ConnectAuthError". Here's my code:

import sys
from getpass import getpass
from jnpr.junos import Device
from jnpr.junos.exception import ConnectError

hostname = input("Device hostname: ")
junos_username = input("Junos OS username: ")
junos_password = getpass("Junos OS or SSH key password: ")

dev = Device(host=hostname, user=junos_username, passwd=junos_password)

try:
    dev.open()
except ConnectError as err:
    print ("Cannot connect to device: {0}".format(err))
    sys.exit(1)
except Exception as err:
    print (err)
    sys.exit(1)


print (dev.facts)
dev.close()​

I don't understand how ncclient works but not PyEz since they both use netconf. I've tried using the root user as well as a 'pyez' user that has read-only rights. Any help would be greatly appreciated.

Hi Joseph.

 'set system services netconf ssh' opens up port 22 for netconf connections, whereas I believe PyEZ tries to log into port 830 by default. Try specifying port 22 when creating your Device() object.
