| 會員 | ping 不到可能只是對方檔掉 ICMP datagram 而已, 不一定表示連不上對方 |

沒事最好不要隨便幹這種事, 曾經看過整個 class C 被國外 tier-1 ISP blackhole 掉的例子. 一般來說, host scan/port scan 都是被視為極度不友善的動作, 可能會被判斷為入侵的前兆. | |

頂多是看一下用什麼系統架的站 http://uptime.netcraft.com/up/graph 如果是正常的站, 應該不會用奇奇怪怪的 PORT. 通常都是地下站比較會用奇奇怪怪的 PORT. 既然是地下掃一下又何訪. 這又讓我想到, 逛百貨公司難道不買就不能看嗎? 走在路上難道不能看一下妹眉漂不漂亮? | |

| 會員 | Ping 跟 掃 Port 是不一樣的，第一種只是用來測試彼此連線的網絡狀態，第二種才是有某種目的，至於好意或惡意就見仁見智啦！ |

像 Netcraft 這種特定的系統辨別測試和 port scan 是不同的. port scan 就好像有人在你家外面敲門敲窗子一樣, 是沒有人會歡迎的. host scan 的狀況也類似, 看到有人每家每戶都去敲敲門, 感覺自然就很不好, 更何況這會造成網路設備不必要的負擔. 或許這還算不上犯法(是個灰色地帶), 但是這種行為不受歡迎是肯定的, 你做了以後可能是你的 ISP 要替你擦嘴. | |

我認為 host scan 只是想知道有哪些人, port scan 是想知道有什麼服務. 就像到店面一看沒有看板, 不知道是做什麼生意, 所以仔細找了一下也問一下店主人. 喔.... 原來這家叫什麼, 喔.... 原來不做正經生意, 純賣白粉. 不犯法可能不代表就是對的. 但是通常掃 port 或是 host ; ISP 或是被掃的人應該有紀錄. 像session wall-3 或是 real secure 等的軟體或是 Server 的 Log 應該都有紀錄. 我的 APACHE WEB SERVER 也有人要這個檔案一堆 [Sat Aug 04 20:20:29 2001] [error] [client 203.204.88.195] File does not exist: c:/mrtg/default.ida [Sat Aug 04 20:22:42 2001]

| 會員 | 老兄我真是服了你了, 這是木馬程式在傳染, 難道你還歡迎光臨嗎? host scan/port scan 之所以不受歡迎, 正因為它往往就是入侵的前兆. 實際上你看到的來源 IP 可能只是個替死鬼, 很多搞不好是在頻寬極大的 colocation 機房裡, 被用來做入侵的跳板而已. 用 traffic 灌爆它? 自己不要先死就不錯了. |
