- SSH Configuration:
hostname Router ip domain-name example.com crypto key generate rsa line vty 0 4 transport input ssh login local
4. Network Troubleshooting:
- Packet Capture: `tcpdump -i eth0 -w capture.pcap` – Captures network packets on interface eth0.
- Interface Statistics: `ifconfig eth0` – Displays detailed interface statistics.
5. Windows Networking Commands:
- IPConfig: `ipconfig /all` – Displays all current TCP/IP network configurations.
- Netstat: `netstat -ano` – Shows active connections and their process IDs.
- Tracert: `tracert
` – Traces the route to a network host.
