Pingga javob bermaydigan mahalliy server bilan muammo qanday tashxis qilinadi?

AIdan javob

  1. Fiziki ulanishni tekshirish:

    • Tarmoq kabeli server va switch (yoki router) ga ulanganligiga ishonch hosil qiling.
    • Serverdagi tarmoq kartasidagi va switch/router portidagi faoliyat indikatorlarini tekshiring. Ular yoniq yoki chiroqlab turishi kerak.

  2. Serverning tarmoq sozlamarini tekshirish:

    • Server yoqilgan va operatsion tizim yuklanganligiga ishonch hosil qiling.
    • Tarmoq interfeysi faol va o’chirilmaganligini tekshiring.
    • IP-manzil, subnet mask va asosiy shlyuzni tekshiring. Ular to'g'ri sozlangan va ping manbai bilan bir xil subnetda ekanligiga ishonch hosil qiling.
    # Linuxda misol
ip addr show eth0  # eth0 interfeysining holati va sozlamalarini tekshirish
ip route show      # marshrutlash jadvalini tekshirish

    # Windows PowerShellda misol
Get-NetIPConfiguration -InterfaceAlias "Ethernet" # Ethernet interfeys sozlamalarini tekshirish
Get-NetRoute # marshrutlash jadvalini tekshirish

  3. Serverdagi firewallni tekshirish:

    • Firewall serverda ICMP so’rovlarini (ping) bloklamaganligiga ishonch hosil qiling.
    • Test uchun firewallni vaqtincha o’chiring (cheklangan muhitda, faqat diagnostika uchun!).
    # Linuxda misol (firewalld)
sudo firewall-cmd --state # firewalld holatini tekshirish
sudo firewall-cmd --zone=public --list-ports # ochiq portlarni tekshirish
sudo firewall-cmd --zone=public --add-rich-rule='rule protocol value="icmp" accept' --permanent # ICMP vaqtincha ruxsat berish
sudo firewall-cmd --reload

    # Windows PowerShellda misol
Get-NetFirewallRule -DisplayName "File and Printer Sharing (Echo Request - ICMPv4-In)" | Select Enabled # ICMP qoidasi holatini tekshirish
# Qoidani vaqtincha yoqing, agar o’chirilgan bo’lsa (administrator huqumlari talab qilinadi)
# Enable-NetFirewallRule -DisplayName "File and Printer Sharing (Echo Request - ICMPv4)"

  4. Tarmoq qurilmalarini ping manba va server o’rtasida tekshirish:

    • Agar server router ortida bo’lsa, uning mavjudligini tekshiring (masalan, ping qilish orqali).
    • Router konfiguratsiyasini tekshiring (firewall qoidalari, marshrutlash).
    • traceroute (yoki Windowsda tracert) yordamida serverga boradigan yo’lni aniqlang.
    traceroute <IP-manzil server>

    tracert <IP-manzil server>

  5. ARP jadvalini tekshirish:

    • Ping manba serverning to’g’ri MAC manziliga ega ekanligiga ishonch hosil qiling.
    # Linuxda misol
arp -a

    # Windows PowerShellda misol
arp -a

  6. Server yuklamasi va operatsion tizim holatini tekshirish:

    • Server haddan tashqari yuklangan yoki operatsion tizim to’xtab qolgan bo’lishi mumkin.
    • SSH orqali ulanishni yoki konsol orqali tizim holatini tekshirishga harakat qiling.

  7. Server va tarmoq qurilmalarini qayta ishga tushirish:

    • Oddiy qayta ishga tushirish vaqtincha muammolarni hal qilishi mumkin.

  8. Server loglarini tahlil qilish:

    • Tarmoq bilan bog’liq xatoliklar uchun serverning tizim loglarini tekshiring (masalan, /var/log/syslog yoki /var/log/messages Linuxda, Windowsda voqea jurnalini).
    • Firewall loglarini tekshiring, agar u o’rnatilgan va faol bo’lsa.
