VPN網路測試
VPN Network Testing

1. 如果你已啟用VPN但仍然無法連上計分版，你可以透過下列方法進行VPN網路相關測試。If you have activated VPN but still cannot connect to the scoreboard, you can perform VPN network-related tests using the following methods.
2. 你可以在終端機使用ping指令檢查是否已連上VPN網路: ping 10.25.0.1。You can use the ping command in the terminal to check if you are connected to the VPN network: ping 10.25.0.1.
3. 若ping指令可以收到正確回覆，請用dig mfctf.ais.org或是nslookup mfctf.ais3.org指令確認網域名稱是否可以正確查詢。上述程式所使用的名稱伺服器應為10.25.7.101，且可正確解析mfctf.ais3.org網域。If the ping command receives proper responses, please use the dig mfctf.ais.org or nslookup mfctf.ais3.org command to confirm if the domain name can be correctly resolved. The name server used by the above programs should be 10.25.7.101, and it should correctly resolve the domain name mfctf.ais3.org.
4. 若ping指令可以收到正確回覆，但系統使用的名稱伺服器不同，或是網域名稱無法正確解析，你可以考慮人工設定名稱伺服器為10.25.0.1。If the ping command receives proper responses, but the system uses a different name server or the domain name cannot be resolved correctly, you may consider manually setting the name server to 10.25.0.1.
5. 若 DNS 查詢問題仍無法解決，本次初賽使用之範例/etc/hosts檔案內容供參考: 127.0.0.1 localhost 10.25.7.101 mfctf.ais3.org 10.25.7.101 pre-exam.ais3.org 10.25.7.111 chals1.ais3.org
