  Agenda • Introduction toPython Networking • Key Libraries • Sockets Programming • Network Automation with paramiko, netmiko, napalm • Packet Inspection using scapy • Real-world Examples • Q&A
• 3.
  Why Use Pythonfor Networking? • Easy to learn and use • Cross-platform compatibility • Rich ecosystem of libraries • Good for automation and scripting
• 4.
  Key Python Librariesfor Networking • socket – Low-level networking • paramiko – SSH protocol handling • netmiko – SSH for network devices • napalm – Multi-vendor network automation • scapy – Packet crafting and sniffing • requests – HTTP communication
• 5.
  Python Sockets: ServerExample • import socket • s = socket.socket() • s.bind(('localhost', 9999)) • s.listen(1) • conn, addr = s.accept() • print('Connected by', addr) • conn.sendall(b'Hello') • conn.close()
• 6.
  Python Sockets: ClientExample • import socket • s = socket.socket() • s.connect(('localhost', 9999)) • print(s.recv(1024).decode()) • s.close()
• 7.
  Automating SSH withParamiko • import paramiko • client = paramiko.SSHClient() • client.set_missing_host_key_policy(paramiko. AutoAddPolicy()) • client.connect('hostname', username='user', password='pass') • stdin, stdout, stderr = client.exec_command('ls') • print(stdout.read().decode())
• 8.
  Simplified Automation with Netmiko •from netmiko import ConnectHandler • device = { 'device_type': 'cisco_ios', 'host': '10.10.10.1', 'username': 'admin', 'password': 'admin' } • net_connect = ConnectHandler(**device) • output = net_connect.send_command('show ip int brief') • print(output)
• 9.
  Configuration Management with NAPALM •from napalm import get_network_driver • driver = get_network_driver('ios') • device = driver('10.0.0.1', 'admin', 'pass') • device.open() • print(device.get_facts()) • device.close()
• 10.
  Packet Inspection withScapy • from scapy.all import sniff • def pkt_callback(pkt): • print(pkt.summary()) • sniff(prn=pkt_callback, count=5)
• 11.
  Real Use-Cases • Monitoringdevice uptime • Backing up router configs • Automating firmware upgrades • Intrusion detection systems
• 12.
  Summary • Python ispowerful for network automation • Multiple libraries support different layers • Use the right tool for the job • Great for both beginners and pros
