Tarmoq holatini tekshirish

Linux serverda muammoni aniqlash uchun interfeys, routing, DNS va socket holatini ketma-ket tekshiring.

ip addr
ip route
ping -c 4 1.1.1.1
getent hosts example.com
ss -tulpn
traceroute example.com

ping ICMP javobini tekshiradi; u bloklangan bo‘lishi mumkin. IP manzilga ping ishlashi DNS ham to‘g‘ri degani emas. getent hosts nom yechilishini tekshirishga yordam beradi.

Troubleshooting tartibi

1. Link va interface holatini tekshiring.

2. IP address va subnetni tekshiring.

3. Default route va gateway'ni tekshiring.

4. DNS resolution'ni tekshiring.

5. Firewall va service portlarini tekshiring.
