Python for Networking Powerful for Automation
- 1. Python for Networking Automate, Monitor, and Manage Networks with Python Presented by [Your Name]
- 2. Agenda • Introduction to Python Networking • Key Libraries • Sockets Programming • Network Automation with paramiko, netmiko, napalm • Packet Inspection using scapy • Real-world Examples • Q&A
- 3. Why Use Python for Networking? • Easy to learn and use • Cross-platform compatibility • Rich ecosystem of libraries • Good for automation and scripting
- 4. Key Python Libraries for 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: Server Example • 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: Client Example • import socket • s = socket.socket() • s.connect(('localhost', 9999)) • print(s.recv(1024).decode()) • s.close()
- 7. Automating SSH with Paramiko • 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 with Scapy • from scapy.all import sniff • def pkt_callback(pkt): • print(pkt.summary()) • sniff(prn=pkt_callback, count=5)
- 11. Real Use-Cases • Monitoring device uptime • Backing up router configs • Automating firmware upgrades • Intrusion detection systems
- 12. Summary • Python is powerful for network automation • Multiple libraries support different layers • Use the right tool for the job • Great for both beginners and pros
- 13. Q&A • Any questions? • Contact info / GitHub link (optional)
