Automation

Hi folks!

I installed ez-library and as is prescribed here https://forums.juniper.net/t5/Automation-Programmability/Python-for-Non-Programmers-Part-2/ba-p/216983 try to establish connection to ex3300 switch, but error occures:

>>> from jnpr.junos import Device
>>> dev = Device(host='10.10.0.10', user='test', password='test')
>>> dev.open()
No handlers could be found for logger "ncclient.transport.ssh"
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/local/lib/python2.7/dist-packages/jnpr/junos/device.py", line 483, in open
raise cnx_err
jnpr.junos.exception.ConnectError: ConnectError(host: 10.127.97.10, msg: 'EntryPoint' object has no attribute 'resolve')

I have found somewhere, that "No handlers could be found for logger "ncclient.transport.ssh"" is because PyEZ tries to connect to NETCONF over the RFC-defined port 830, so i added port parameter, this line about handlers disappeared, but all the rest is here:

>>> dev=Device('10.127.97.10',user='user',password='passwd',port=22)
>>> dev.open()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/local/lib/python2.7/dist-packages/jnpr/junos/device.py", line 483, in open
raise cnx_err
jnpr.junos.exception.ConnectError: ConnectError(host: 10.127.97.10, msg: 'EntryPoint' object has no attribute 'resolve')

Any thoughts where the cause is?

Thank you in advance!

Hi,

This sounds like netconf hasn't been configured on the device, although, it might also be worthwhile checking to see which version of ncclient is installed too (pip  show ncclient), and upgrade it to 0.4.7 which is the latest stable release for Python2 as of Jan 2016).  e.g.  "pip install -U ncclient" or "pip install ncclient==0.4.7) etc.

system {
    services {
        netconf {
            ssh;
        }
    }
}

Regards,

Andy

Hi Andy,

checked both things: netconf on device is configured as like you showed, and version of ncclient on server is exactly 0.4.7

Umm..... not a message that I've seen before, and took a look through my archives and still none the wiser.

Could you check the following versions and see if you get any differences...?

junos-eznc : 1.3.1
lxml : 3.6.0
ncclient : 0.4.7
setuptools : 20.4
paramiko : 1.16.0
scp : 0.10.2
jinja2 : 2.8
PyYAML: 3.11
netaddr : 0.7.18

Hello everyone.

I have the same message here in my test. I'm try to work with MacOSX 10.11

HunterNET:PyEz JN$ python teste.py 
No handlers could be found for logger "ncclient.transport.ssh"
Traceback (most recent call last):
  File "teste.py", line 5, in <module>
    dev.open()
  File "/Library/Python/2.7/site-packages/jnpr/junos/device.py", line 787, in open
    raise cnx_err
jnpr.junos.exception.ConnectError: ConnectError(host: 10.151.10.228, msg: 'EntryPoint' object has no attribute 'resolve')

Any help will be great.

Hello Asharp,

I did a downgrade from my Cryptography package from Python and they works fine.

sudo pip install cryptography==1.2.1

I found this issue in: 

Cannot get dev.open() to work

Thanks for your help.

I'm having this same issue too.

[root@centos6 junos_python_scripts]# python2.7 dev_facts.py
No handlers could be found for logger "ncclient.transport.ssh"
Traceback (most recent call last):
File "dev_facts.py", line 7, in <module>

raise cnx_err
jnpr.junos.exception.ConnectError: ConnectError(host: 10.0.0.1, msg: 'EntryPoint' object has no attribute 'resolve')

And I did this to fix it:

Here is the new output
