I am using Windows and trying to run this python code as mentioned below but unable to get past this error:
from jnpr.junos import Device
ModuleNotFoundError: No module named 'jnpr'
The script is pretty straightforward as outlined in document below:
https://kb.juniper.net/InfoCenter/index?page=content&id=KB34524&cat=MX_SERIES&actp=LIST&showDraft=false
In the following example, we are connecting to the address: 10.1.1.1, with the user root and Password: test123 using Python Script:
from pprint import pprint
from jnpr.junos import Device
from jnpr.junos.utils.start_shell import StartShell
hostname= Device(host='
10.1.1.1
', user='
root
', password='
test123
'
)
ss = StartShell(hostname)
ss.open()
hostname.open()
pprint(ss.run('cli -c "show version | no-more"')) #
<-- For regular CLI commands
pprint(ss.run('cprod -A fpc0 -c "show route summary"')) #
<-- For VTY commands
hostname.close()
ss.close()
Save the above contents as ".py" file and run it using the following command:
python3 filename.py
You can also save the outputs to a file instead of printing them on the console:
python3 filename.py> save logfile.txt
Greetings,
This error is because of reason that the module not installed and you are trying to use it.
Use this link :

That is the first thing that I have tried but it didnt work.
I have tried this on python3 and I get the following error:

I also used Pycharm but that fails on error too:

Any help would be much appreciated.

There seems to be indeed any issue with the junos-eznc package. It worked for me with Python 3.7.3, then I upgraded to 3.8.3 and loaded the junos-eznc again, now I get the error message:
>>> import jnpr.junos
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
[...]
ModuleNotFoundError: No module named 'fcntl'
I have managed to successfully connect to my router but using Linux not Windows. think there is an issue with windows and jnpr.junos.
My next query is how to I make my output look user friendly as its all fudged up.from pprint import pprint
I also need to run command show chassis hardware to get s/no of unit but that is not showing either.
Please anyone help.
from pprint import pprint
from jnpr.junos import Device
from jnpr.junos.utils.start_shell import StartShell
hostname= Device(host=1.1.1.1, user='root', password='eb08fb5d')
ss = StartShell(hostname)
ss.open()
hostname.open()
pprint(ss.run('cli -c "show version | no-more"')) # <-- For regular CLI commands
pprint(ss.run('cprod -A fpc0 -c "show route summary"')) # <-- For VTY commands
hostname.close()
ss.close()
Please execute this on your Windows environment:
pip install git+
https://github.com/Juniper/py-junos-eznc.git
After performing this it should work. At least it worked for me.
It appears my code only runs on old python 2.7.8 if anything above 3 is used it fails.
I have tried to run pip install git+
https://github.com/Juniper/py-junos-eznc.git
but getting below error:
ERROR: Error [WinError 2] The system cannot find the file specified while executing command git clone -q
https://github.com/Juniper/py-junos-eznc.git

ERROR: Cannot find command 'git' - do you have 'git' installed and in your PATH?
Make sure that you've just installed Python 3 (doesn't matter if 3.7 or 3.8)
At first, if not already present, install GIT for Windows:
https://git-scm.com/download/win
After that, reboot your device.
Then try to upgrade pip:
python -m pip install --upgrade pip
After that execute the download of junos-eznc again:
pip install git+
https://github.com/Juniper/py-junos-eznc.git
After that it should work:

Many thanks Sir your solution with git has saved me.
I have run this code now and it works however indentation is not great with lots of \r\n etc
(True,
'cli -c "show version | no-more"\r'
'\r\n'
'Hostname: Test001-001\r\n'
'Model: srx300\r\n'
'Junos: 15.1X49-D150.2\r\n'
'JUNOS Software Release [15.1X49-D150.2]\r\n'
'root@Test001-001% ')
(False,
'cprod -A fpc0 -c "show route summary"\r'
'\r\n'
'================ scb ================\r\n'
'Broken pipe\r\n'
Any ideas how to get rid of all these \r\n to make out look bit pretty?
please check if this helps you to get rid of these characters:

Hi Simon
The startshell function actually returns a tuple with the first element as True/False and second element as the output of the command.
You can try to print the second element of the tuple to print only the output.
Also you can use the links suggested by F1ght3r to remove /r/n from the output.
I have a requirement to logon to juniper devices using a port other than ssh 22 - This mean to ssh but using port say 8022 instead.
How do I edit this code or has any one got some examples:
from pprint import pprint
from jnpr.junos import Device
from jnpr.junos.utils.start_shell import StartShell
hostname= Device(host='
10.1.1.1
', user='
root
', password='
test123
'
) ** port required is 8022 instead of 22**
ss = StartShell(hostname)
ss.open()
hostname.open()
pprint(ss.run('cli -c "show version | no-more"')) #
<-- For regular CLI commands
pprint(ss.run('cprod -A fpc0 -c "show route summary"')) #
<-- For VTY commands
hostname.close()
ss.close()
Save the above contents as ".py" file and run it using the following command:
python3 filename.py
You can use the port parameter from the Pyez and that should work.
hostname= Device(host='
10.1.1.1
', user='
root
', password='
test123 , port = 8022
'
)
By default the port will be 22.
Make sure that device also has the same port configuration for ssh otherwise the connection will be refused.
Hope this helps.
I get an error
retry_on_signal(lambda: sock.connect(addr))
TimeoutError: [WinError 10060] A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond
This works fine if you make ssh connection using port 8022 though.
Just checked. StartShell code is using port 22 only. This was done because, PyEZ use 830 port for netconf.
Looks like startShell left it hard coded for 22. We might need to look into this.
I think start shell uses the paramiko to access the shell and in the startshell code i do not see port number so you are right the port 22 is hardcoded. However if you directly use paramiko you may get the option for port. However i am not sure if the junos will allow the ssh from a different port number for an inbound connection.
Yes, you are right, seems to be a known issue on the Web.
As per my understanding something is blocking this on your device. This might as well be due to antivirus/firewall. Verify if the
project settings has the module(jnpr) installed in PyCharm also
.
Refer this python forum thread for a few steps to resolve this.
Bypassing the Firewall or running as admin might be of some help:
https://python-forum.io/Thread-Import-Error-jnpr-junos
Let me know if this works.
Hope this helps.
