助教您好,我是學號112950026
我也發生了和其他同學類似的問題:
router和cp1都已經加入了judge的ssh pub key,router wireguard也正常運作中:
judge@router
:
~
$ sudo wg show wg0
interface
:
wg0
public key
: RxgopjfScXv/kypGj9jUrb+VQCy3gdgTdpM4EoYMThQ=

我用
sudo journalctl -u sshd 並沒有看到OJ嘗試連入
感謝助教
Best Regards,

助教好 已經解決了
原來是router在HW1的防火牆設定會擋住VPN來的ssh連線
我自己拿掉該規則後就有看到文字說明:
Note that this conflicts with the HW1 rules. Please remove that rule when proceeding with HW2-1.
但要先通靈修好才能看到,再麻煩助教改進OJ了
謝謝助教
