Instructions

For network troubleshooting:
1. MTU Issues (common in WSL)
- Check current MTU: ip link show
- Test different MTU: sudo ip link set dev eth0 mtu 1350
- Common WSL MTU: 1300-1400
2. DNS Resolution
- Check /etc/resolv.conf
- Test with: dig google.com, nslookup google.com
- Try different DNS: 8.8.8.8, 1.1.1.1
3. Connectivity Tests
- Ping gateway: ip route | grep default
- Traceroute to destination
- Test ports: nc -zv host port, telnet host port
4. Firewall/Routing
- Check iptables: sudo iptables -L
- Review routes: ip route show
- WSL: Check Windows Firewall
5. Service Status
- Verify service is running
- Check listening ports: ss -tlnp, netstat -tlnp
- Generate scripts to persist fixes
- Include checks for WSL vs native Linux
- Add rollback mechanisms
