Telnetlib output into text file to be called on as a variable later

I have a program that i'm trying to create for the purpose of searching the network for specific mac addresses.
When I run the cisco command "show mac-address-table" it gives output that's saved to MH2. If that output has "000c." in it all the output is saved into a txt file that i'm hoping i'll be able to filter through and pull the vlan from based on the command used (show mac address-table vs show mac-address-table) as the vlan location for the line with the mac address could be to the left or the right. I'm planning on figuring that part out later, but for now it doesn't seem that my script is reading the file(which is getting the correct output and has a "000c." entry in it) I'll enter the code below:
#!/usr/bin/env python3
from time import sleep
import telnetlib
from getpass import getpass
# f is the .txt document that lists the IP's we'll be using.
f = open("devicess.txt")
#
username = input("please provide your username:")
password = getpass()
#
for line in f:
device = (line)
print('Starting to collect information, please wait')
#For those devices in the above list, connect and run the below commands
def loopstart():
for device in f:
tn = telnetlib.Telnet()
tn.open(device, 23, 20)
#Remove # in the line below for debug
#tn.set_debuglevel(2000)
tn.read_until(b"Username:", timeout = 20)
sleep(.25)
tn.write(str(username + "\n").encode("ascii"))
sleep(.25)
tn.read_until(b"Password: ", timeout = 10)
sleep(.25)
tn.write((password + "\n").encode("ascii"))

"if ("000c.15") in (CPMAC)" is the part of the code that I believe i'm having trouble with. any help is appreciated!

Not really sure what you are trying to achieve but check the line OP1 = mactable.read read is a function that should be written as OP1 = mactable.read()

So the below is what has worked for me so far, I'm able to run the command "show mac address-table", take that output and put it into a text file, search line by line through the output for 000c.15 and use that line for further output later down the road. I think the important thing was to decode the output(bytes) into a string before writing it to the text file. Also, using the seek(0) function was helpful for taking me back to the beginning of the txt file before starting to read. Line.strip seems to get rid of all the white space being interpreted as lines. not 100% sure on that last one. Still having issues with getting that code to send the command but i'm making progress at least. Thanks everyone for your help.
if (b"000c.15") in MH2:
print("000c.15 in MH2, line 57")
try:
print ("line 59")
sleep(.5)
mactable = open("mactable.txt", "w+")
mactable.seek(0)
mactable.write(MH2.decode('utf-8'))
mactable.truncate()
mactable.seek(0)
OP1 = mactable.readlines()
for line in OP1:
line = line.strip()
CPMAC = line

python ssh paramiko save to file

I would like to save to file all my output from ssh connection(s). The ssh connection works fine, the output is ok too to a stdout. I want to create a file for every connection individually in a file. I have changed the output lines to the lines below and also moved it above
output_filename = ip_address + ".txt"
file = open(output_filename, 'w')
file.write(output.decode)
file.close()
What is missing?
I receive this error:

And it just don't save the output. the file is created, but in blank.

This happens only in Python3, because except now expects a class that is a subclass of BaseException. And the integer 10060 is not.
>>> try:
... raise ValueError
... except 10080:
... print('dfsdf')
...
Traceback (most recent call last):
File "<stdin>", line 2, in <module>
ValueError
During handling of the above exception, another exception occurred:
Traceback (most recent call last):
File "<stdin>", line 3, in <module>
TypeError: catching classes that do not inherit from BaseException is not allowed
So Paramiko is raising some other error, but error handling dies when it tries to evaluate the except 10060 statement.

Netmiko library returns pattern never detected in send_command_expect

I am working as a network engineer and I have tried to automate routine tasks with some python scripts. We are using cisco so I thought it would be nice to implement netmiko library.
Here is the part of the script which is used to connect to device and edit access-lists:
def Connection (DevParameters, device, HostAddress):
try:
net_connect = ConnectHandler(**DevParameters)
except:
print device[0] + ': Authentication failed or device unavailable'
return
access_class = net_connect.send_command("sh run | inc access-class")
if access_class == '':
print device[0] + ': No access-class configured.'
net_connect.disconnect()
return
access_class = access_class.splitlines()[0].split(' ')[-2]
acl_type = net_connect.send_command("sh ip access-list " + access_class).splitlines()[0].split(' ')[0].lower()
net_connect.send_command('configure terminal')
net_connect.send_command('ip access-list ' + acl_type + access_class)
if acl_type == 'extended':
net_connect.send_command('permit tcp host' + HostAddress + ' any eq 22')
elif acl_type == 'standard':
net_connect.send_command('permit ' + HostAddress )
else:
print device[0] + ': Unexpected ACL type. Connection closed.'
net_connect.disconnect()
return
print device[0] + ': Configured.'
net_connect.disconnect
return
It works nicely from IDLE writing command line by line but when executing script it fails with:
Traceback (most recent call last):
File "C:\Users\User\Desktop\MAT.py", line 145, in <module>
Connection (DevParameters, device, HostAddress)
File "C:\Users\User\Desktop\MAT.py", line 90, in Connection

search_pattern))
IOError: Search pattern never detected in send_command_expect: HQ\_F3\_2960\_D\-5\#
I tried to implement sleep() after send_command() to no avail. What could be the issue?

I've got a similar problem, but I solved it with set length 0.
I share my code, I hope to help you.
extrm_X460 = {
'device_type': 'extreme',
'ip': ip,
'username': 'username',
'password': 'password',
'port' : 22,
}
try:
# Connect
print "Trying to connect to: " + ip
net_connect = ConnectHandler(**extrm_X460)
# Get info
print "Connected to: " + ip
net_connect.send_command('set length 0')
output = net_connect.send_command('show mac port ge.*.*')
print output
except (IOError, EOFError, SSHException, NetMikoTimeoutException, NetMikoAuthenticationException) as e:
print e
continue

Use send_command_timing instead of send_command.
send_command is detecting a device prompt (pattern-based) (it will work with "show" commands).
send_command_timing is delay-based and doesn't look for the device prompt (will work in configuration mode [conf t])
Example: net_connect.send_command_timing

Python ftplib.dir() Function Not Working

I Have this Code... i want to see this directory on my ftp server. In that dir i have 3 files but my code reads only 2. And it throws an error which i handle. Take a look on the code and the output
import datetime
import ftplib
import os
errors = 0
default_ftp_name = 'username'
default_ftp_pass = 'pass'
host = 'ftp.example.com'
print('Connecting To ' + host)
try:
ftp = ftplib.FTP(host)
print('Successfully connected! ')
except:
print('[!]Failed To Connect')
errors += 1
print('Logging with: ' + default_ftp_name)
try:
ftp.login(default_ftp_name,default_ftp_pass)
print('Login Success')
except:
print('[!]Couldnt log in')
errors += 1
print('Changing Directory to /Public/ConnectedUsers/')
try:
ftp.cwd('/Public/ConnectedUsers/')
except:
print('[!]Directory failed to change')
errors += 1
try:
print('Retrieving Files...')
files = ftp.dir()
print(files)
except:
print('[!]Didnt Get The Files')
errors += 1
print('[t] Total Errors: ' + str(errors))
connection = False
if connection is True:
#Dosomehting
var = 10
else:
print('Connection Error')
See the output right here.
it shows 2 items but i have 3.
What do i need to change in order to access all files?
Take a look here

ftp.dir prints the output to stdout, so files is currently None. You want to replace that call with ftp.nlst (or ftp.retrlines with a callback handler). See the docs.

Multithreading my simple SSH Brute forcer

I've coded a simple SSH Bruteforcer , and I am trying to make it multi-threaded as it is running very slowly at the moment. As you can see in the last few lines I have given it an attempt, but don't understand threading fully. I have read a few examples but I don't quite understand it fully, so I felt adding into my program will make me understand it better.

The problem is embarrassingly parallel. You can run concurrently the ssh connection attempts both for different ips and passwords:
#!/usr/bin/env python
# remove .dummy to use processes instead of threads
from multiprocessing.dummy import Pool
def check(params):
ip, username, password = params
# emulate ssh login attempt #XXX put your ssh connect code here
import random
successful = random.random() < .0001
return successful, params
def main():
creds = {}
ips = ["168.1.2.%d" % i for i in range(256)] #XXX dummy ip list, use yours
usernames = ["nobody", "root"] #XXX dummy user list, use yours
def generate_args():
for ip in ips:
for username in usernames:
for password in generate_passwords():
if (ip, username) in creds:
break
yield ip, username, password
pool = Pool(processes=20)
for success, params in pool.imap_unordered(check, generate_args()):
if not success:
continue
print("Found: %r" % (params,))
ip, username, password = params
creds[ip, username] = password
pool.close() # no more tasks
pool.join() # wait for all tasks in the pool to complete
if __name__=="__main__":
main()
where ips is a list if all ips you want to try and generate_passwords() is a generator that yields one password at a time, here's an example:
def generate_passwords(pass_file):
return (line.strip() for line in open(pass_file))
About errors
ValueError: too many values to unpack
your code has found.put((username,password,ipaddress)) (a tuple with 3 values) but print_results() function expects ip, password = found.get() (2 values). The error "too many values to unpack" is because 3 is larger than 2.
'NoneType' object is not iterable
attempt() function returns nothing (None) but you put it in the place for generate_passwords() that must generate passwords (see the example implementation above).
