Network Info

Gather network configuration and connectivity details on Linux including interfaces, IP addresses, routing tables, DNS settings, and listening ports. Use when the user asks about IP configuration, network interfaces, connection issues, DNS resolution, open ports, routing, or network troubleshooting. Use when this capability is needed.

Network Information Skill

Explores network configuration and connectivity on Linux systems.

Suggested Workflow

Run ./scripts/netinfo.sh for a structured overview of interfaces, IPs, routes, DNS, and listening ports.
Check ip addr for interface status and assigned addresses.
Verify routing with ip route and DNS with cat /etc/resolv.conf.
Inspect listening services with ss -tuln to identify open ports.

Commands Reference

Network Interfaces

ip addr or ip a - Show all network interfaces and IP addresses
ip link - Show interface status (up/down)
cat /sys/class/net/*/address - MAC addresses

Routing

ip route - Show routing table
ip route get 8.8.8.8 - Show route to a specific destination

DNS Configuration

cat /etc/resolv.conf - DNS servers
cat /etc/hosts - Local host mappings
systemd-resolve --status - DNS status (systemd systems)

Active Connections

ss -tuln - Show listening TCP/UDP ports
ss -tupn - Show established connections with process info
cat /proc/net/tcp - Raw TCP connection data

Network Statistics

ip -s link - Interface statistics (bytes, packets, errors)
cat /proc/net/dev - Network device statistics

Tips

Use ip commands (modern) over ifconfig/netstat (deprecated)
The -n flag prevents DNS lookups for faster output
Check ss -tuln to see what services are listening
