Paramiko with PaloAlto

Mohit — Sun, 04 Dec 2016 21:27:29 GMT

Hi There,

I am very new to Python scripting and have started to learn through my lab PaloAlto Firewall.

I wrote a basic script to just return me the output of an operational command. This script works on my lab SRX but hangs on the PaloAlto.

The code snippet : (indentation is correct)

root# vi PAoutTest.py

#!/usr/bin/python

import paramiko
import time
import inspect

ssh = paramiko.SSHClient()

ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())

timeout = 30

endtime = time.time() + timeout

iin = paramiko.sys.stdin
out = paramiko.sys.stdout
err = paramiko.sys.stderr

ssh.connect("x.x.x.x",username="xxxxx",password="xxxx")

iin, out, err = ssh.exec_command("show clock")

print out
#print out.read()

while not out.channel.eof_received:
time.sleep(1)
if time.time() > endtime:
out.channel.close()
break
print out.read()

I have included a while loop because without it the script would just hang forever and I have to manually kill the process.

So after the while loop the script times out without providing any output.

Is this not possible with PaloAlto or only way to automate is via API?

Please help.

Yes it is possible to log into the Palo Alto using Paramiko, as long as you get all the timing and everything correct.

I use this instead of using exec, I believe exec is only able to run one command.

channel = ssh.invoke_shell()
output = channel.recv(10000)
print output
print "connected to device"

channel.send('show interface all\n')
output3 = channel.recv(1000000)
