無理由會知我的ip address, 然後打入來試.

SuiYan

謝謝.

立即改了, 和加強了密碼.

SuiYan

謝謝. 我沒有開port 21/22 給router 入來.
我要時. remote wake on lan Power-on屋企部電腦, 再vnc 電腦去telnet/ssh..
另外PORT 8088 也沒有對外開放.

連續鑑測asterisk log, 這3天入有不斷入侵.
今天最利害, 全日每2小時一次, 每次半小時, 幾秒一次入侵. 早上8點至到現在.
所以, 剛剛關了那asterisk 和 router port forward.

SuiYan

我昨晚睡前. 把bb modem關掉. 好讓hkbn把我的ip address轉換另一個.
看看入侵者是根據IP ADDRESS 還是根據 DDNS DOMAIN

SuiYan

發現有些來源.

話說. 轉了ip Address後, 2天也沒有發現有被attack.
但今日下午約3:30. 在手機用過iptel.org 打過電話返屋企, 打的電話用 1234@xxxx.ddns.org 和
linphone.org 打去我的1234@xxxx.ddns.org.

跟住. 在5點多, 就開始發現有被ATTACK.

我的是nas, 放在buffalo link station pro
