I am fairly new to Paramiko so my apologies if this question has been answered already
I am trying to automate login and execution to a PAN Firewall. The FW output is as follows:
Last login: Wed Apr 27 11:54:01 2022 from 10.54.90.24
Number of failed attempts since last successful login: 0
admin@PA-5440-F03_31> show transceiver-detail all
My code is below:
>>> import paramiko
>>> command = "show transceiver-detail all"
>>> client = paramiko.client.SSHClient()
>>> client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
>>> client.connect(hostname, username=username, password=password)
>>> _stdin, _stdout, _stderr = client.exec_command(command)
>>> client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
>>> client.connect(hostname, username=username, password=password)
>>> _stdin, _stdout, _stderr = client.exec_command(command)
My problem is that when I read _stdout:
>>> print(stdout.read().decode())
I get only the banner:
'\n\n\nNumber of failed attempts since last successful login: 0\n\n\n\n'
How do I get to the point where exec_command returns an output that is captured by stdout?
NOTE : I had to explicitly close the _stdout channel (_stdout.channel.close() ) before the read command worked. Not sure if this is standard procedure or if there is something I need to do to ensure the channel closes automatically.
Turns out that PAN has its own Python module - pandevice - that handles this issue.
from pandevice.firewall import Firewall
import xml.etree.ElementTree as ET
fw = Firewall(hostname, api_username=<username>, api_password=<password>)
result = fw.op(cmd='show transceiver-detail all')
>>> type(result)
<class 'xml.etree.ElementTree.Element'>
