This directory contains Scripts which explains how to use Paramiko Library for communicating with Cisco Devices.
* Demonstrates the use of SSH Hostkey policy. Different ways to use hostkey policies :
```
session.set_missing_host_key_policy(paramiko.AutoAddPolicy())
session.load_host_keys('/home/evolve/.ssh/known_hosts')
session.set_missing_host_key_policy(paramiko.WarningPolicy())
```
* SSH Keybased Authentication Using Paramiko:
* Paramiko SSH exec_command Example
* Paramiko invoke_shell example
* SSH Password Based Authentication

## Directory : [02_Configure_Device_Using_CSV](https://github.com/network-evolution/Python_for_Network_Engineers/tree/main/02_Configure_Device_Using_CSV)
This directory contains Scripts which explains how to read Device IP Address and configuration lines from CSV file and configure respective devices using Python.
* Sample CSV FIle Used for Configuring the Device :
* The above CSV file will create a Dictionary in below format
```
conf_dict={'192.168.0.50': ['terminal len 0',
'config t',
'int gi1',
'no shut',
'exit',
'exit',
'show ip int brie',
'show run int gi1'],
'192.168.0.51': ['terminal len 0',
'config t',
'int lo0',
'ip add 10.0.0.1 255.255.255.0',
'int lo1',
'ip add 11.0.0.1 255.255.255.0',
'do show run int loopback0',
'do show run int loopback1'],
'192.168.0.53': ['terminal len 0', 'config t', 'int gi3', 'no shut'],
'csr1.test.lab': ['terminal len 0',
'config t',
'int gi2',
'no shut',
'ip address 2.2.2.2 255.255.255.0',

## Directory : [03_Cisco_Config_Parser_Regex](https://github.com/network-evolution/Python_for_Network_Engineers/tree/main/03_Cisco_Config_Parser_Regex)
This directory contains Scripts which explains how to parse configuration lines from Cisco Devices Using Regex in Python
### Sample Parsed Output :
*Show Version Parser
*Show Running Config Parser Output:
* Regex Patterns Used for Show Version Parser:
```
version_pattern = re.compile(r'Cisco .+ Software, Version (\S+)')
model_pattern = re.compile(r'cisco (\S+).+bytes of memory\.')
serial_no_pattern = re.compile(r'Processor board ID (\S+)')
uptime_pattern = re.compile(r'(.+) uptime is (.*)')
```
* Regex Patterns Used for Show running Parser:
```
hostname_pattern = re.compile(r'hostname (\S+)')
domainname_pattern = re.compile(r'ip domain name (.+)')
pid_pattern = re.compile(r'license udi pid (\w+) sn (\S+)')
netconf_pattern = re.compile(r"netconf-yang\r\n")
username_pattern = re.compile(r'username (\S+) privilege (\d{2})')
interface_pattern = re.compile(r'interface (\S+[.]?\d*)\r\n.+?\r?\n?\s?ip address ([\d\.]+) ([\d\.]+)')
interface_prop_pattern = re.compile(r'interface (?P\S+[.]?\d*)\r\n\s?.+?\r?\n?\s?ip address (?P[\d\.]+) (?P[\d\.]+)')
default_route_pattern = re.compile(r'ip route 0.0.0.0 0.0.0.0.+?([\d.]+)\r\n')
static_route_pattern = re.compile(r'ip route (?P[^0][\d\.]+) (?P[^0][\d\.]+) (?P[\d\.]+)')
