香港的GFW?
September 21st, 2006 by sidekick

認屎認屁,我懷疑我是提得最多 GFW 的香港 blogger。

年初時在豆瓣的豆郵,就有來自國內的會員告訴我:

很久前就看你的 blog过的,
从你那里才知道 GFW 那样可恶。

甚麼是 GFW?請看 Zola 的這篇,內有 isaac 關於 GFW 的解說及運作猜想圖。

作為一名香港 blogger,我很慶幸自己是香港人;自己的主blog已被內地GFW了年多了,我對於這些 censonship 當然心痛惡絕,而更深深體會到我可以在網上世界隨意馳騁的可貴。

在wikipedia 關於 GFW的條目,有以下的一段:

Internet censorship in the People’s Republic of China is covered under a wide variety of laws and administrative regulations. In accordance with these laws, more than sixty Internet regulations have been made by the People’s Republic of China government, and censorship systems are implemented variously by provincial branches of state-owned ISPs, business companies, and organizations.[1][2] The special administrative regions of Hong Kong and Macau have their own legal systems, so censorship does not apply there.

但,我懷疑原來香港也有 GFW、censorship!!
管制我們的,並不是特區政府,而是比政府更惡的人。

你在用哪家 ISP?我們一起來做個實驗:
你可以登入這個登入名為《不是南華早報》(Not The South China Morning Post www.ntscmp.com)的網站嗎?
是空白一片?還是大概像這個樣子?

ntscmp

我用“大概”,因為我用的是《網上行》,我不能成功登入那個網站,上面這幅圖,是我經google 的cache才看到的。
你也可以透過browseatcollege.com,用proxy server瀏覽 NTSCMP:

根據《Letters from China》的這篇“李澤楷法中共封網站乎?”所言,www.ntscmp.com是先被《網上行》封殺,後被《和記寬頻》封殺。

我不理www.ntscmp.com網站內有甚麼內容!
就算它是一個三仔四仔人獸交快閃強姦黨大中華救國聯盟網站也好,作為一家ISP,如果你替我封掉它不讓我瀏覽就是你不對!

以下,是 mister bijou 給電訊管理局(consumercomplaint@ofta.gov.hk) 的投訴信範本,大家可參考及參與投訴!
Blogger 們,請注意,請正視此事!(起碼,請留意此事的發展):wink:

I am a subscriber of PCCW’s Netvigator service.
Recently, I have attempted to access the website www.ntscmp.com but was unable to.
At first, I thought the website was down. But then it came to my attention that the website was still running, but it had been blocked by PCCW. I was prevented by PCCW from accessing ntscmp.com from my Netvigator account. I confirmed this by accessing the website at work, and found it to be working normally.
The administrator of ntscmp.com claims the site is being purposely blocked by PCCW. HGC have also blocked the site.
I am very upset that PCCW has decided to censor what I may access on the internet. I am a paying subscriber and I am entitled to access any internet site I wish. I cannot easily switch to another service provider, as I live in Causeway Bay and there are few others.
Please do something about this at once. I believe PCCW may be in violations of its licence conditions.

    最近網上鬧得熱哄哄的Not the South China Morning Post事件, 終於被推到上…

    係喎,係最下面,之前都留意唔到…:P
    其實而家肯定原因到未?
    嗯,再睇多一次呢到既留言,
    有少少意見…(愚見)
    一個網站站長如果想 Block 一個地方 既 IP,
    其實可以好簡單咁淨係 block 個 ISP
    即係可以輸入想 block 既 ISP 名,
    例如:填入 “netvigator.com” 就可以禁止所有 netvigator.com 用戶上泥,
    因為通常一間 isp 都唔止一組 ip 字頭,
    就咁入個名會簡單好多。
    (估計大部份日本素材網站都係用呢個方法去禁止我地香港人上去)

    所以又估計 NTSCMP 既站長如果想無風起浪,
    佢應該可以玩得盡 D,而唔係有人上到有人上唔到…

    踢踢,您可以再了解一下,
    有人話用 netvigator 上到去,
    咁上到去既人佢部電腦有無裝一 D 轉 ip 既軟件?
    (因為記得以前好多人上論壇上 news group 都鍾意隱藏自己個 ip,所以用左 D 軟件去轉個古靈精怪既 ip。
    踢踢,您以前都有過個疑問,
    話有組好特別既 ip 一日上泥妳到好多好多次,
    如果妳有再留意,會見到佢果 D ip 係跟時間順序咁去架!!)
    所以,會唔會有 D 人轉左 ip 所以變左佢地上到去呢?

    嗯…嗯…
    我公司係用 netvigator 既,
    固定 ip 字頭係:219.
    我都上唔到去 ^^

    再最後,仲有一個解釋,
    您記唔記得我個 wp admin 裡面,
    匯入功能到又係出全白畫面?
    最後我係公司另一個同事部腦到竟然就開到喇,
    好莫名奇妙,係咪?
    咁 NTSCMP 網主最近有無更新過網站上用緊既程式??

    我用和記都睇唔到ntscmp,正如sidekick話齋,好彩我o向香港,有人要封殺,用戶都可以o向其他途經瀏覽到,反而仲整衰自己個”朵”。

    >Kli
    Server與router之間可以隔了數個供應商(hosting,datacenter),每個供應商都可以做到Blocking (via Firewall/Server software)的,但基於Server連線來源五湖四海,為了避免錯手Block了自己client,一般而言hosting和data center都不會Block ip(DoS的例外,但即使會Block也不會block到class A這麼狠)…大多數Blocking都是Site level做的

    即是可能是該網Admin Block了…但我用網上行的機今天再上ntscmp,該網說他們以及fortunecity沒有block香港ip…

    “ntscmp.com owner George Adams said that this hosting service Fortune City is saying that the blocking originated from Hong Kong and netizens outside of Hong Kong can view his website normally. He said that he could do nothing after the denials by Netvigator and Hutchison Global. Local website InMediaHK cited Fortune City which hosts ntscmp.com as saying that the company does not block Hong Kong users and that this is possibly something that the Chinese government is doing. But the company did not explain further.”

    另外,在DNS內的Record Domain owner並不是fortunecity喔~(fortunecity只是負責收那個domain的錢)

    whois內有一個 Administrative Contact和Technical Contact的,要問應該是用那個問…(搞笑的是,Admin Contact留的email居然是網上行的@_@)

    >Sidekick
    應該是extension作怪(裝太多了=_=)

    >To All
    APNIC管的不止亞洲,還有澳洲,所以如果Block class A.class B澳洲去不到是有可能的

    至於inmedia那位黃先生…對於連bot和human visitor都分不清的人說的Networking最好一笑置之

    反而是,我用了不同的source做了一下tracert結果有點奇怪:
    HopOne.com->Telus.com(x3)->megawebservers.com
    Nevigator.com->Cogentco.com(154.54.5.* -> timeout)
    Hinet(210.65.*)->Cogentco.com(154.54.5.* -> timeout)
    I-cable->Level3.com->Telus.com->timeout
    懷疑自己被Block的人可以試試在command prompt(run->cmd)內打tracert ntcmp自己做…
    不過即使沒有被Block也可能在某些點Loss了…
    問題可能出在Cogentco或Telus…不一定是ip blocking,可能出在他們的機上(尤其是上到一半會斷線的話更像:Charles Mok said that more tests have shown that Hong Kong users can reach the website, but then they are immediately interrupted from viewing.[23th Sep 06, NTSCMP])
    建議有心人問問這兩家公司,看看是IP Blocking還是更單純的線路/Firewall問題…
    總之,這件事真的很詭異…(愈多人的試驗引出來的可能性更多了)

    原打算另撰文,不過還是算了(因為 sidekick 處人流多:P)。主要是幾點補充和更正:

    Steve 說得對,網上行(Netvigator)所分派的不是 Class A Network,而是 Class C。煩請查看 wikipedia。我想是跟 subnet (子網絡) 混淆了?

    此外,我在文中已提過,tracert(Traceroute) 的結果不能作準,因為好些路由器不會告訴你封包已過期,而直接丟掉,更不會回應 ping 測試封包。所以沒回應基本上是頗常見的。(要證實,可以找個正常的網域 trace 一下,也會有機會有沒回應的路由器。

    第三是 IP 阻擋問題。如果是經防火牆 (例如 iptables/ipchain)阻擋 IP,便不會有我曾提過的「先連線,後斷線」的現象,而 FTP 也不會有回應了。反之,現在見空白頁有兩種可能性:對方伺服器設定「錯誤」或某中途路由器設定「錯誤」。沒有伺服器的封包清單我們不可能知道發生甚麼事。

    最後,現在問題是仍有一班網上行/HGC 用戶可正常瀏覽該網站,還有一班不能瀏覽該站的非網上行/HGC 用戶。我建議這班用家應 1. 試試可不可以從 FTP 登入該網站 2. 公佈自己 IP 地址的頭兩組數目字,或許我們可以從中找出共通之處。

  • mk writes:
    September 26th, 2006 at 3:29 pm

    那好吧,順便一答。

    DNS 指 Domain Name Service,即把 hostname/domain name (如 sidekick.myblog.hk) 翻成電腦看懂的 IP (202.134.73.45)的一種服務。rDNS 我猜是 reverse DNS, 應該是從 IP 找回 hostname 吧。因為許多時候主機會沒有 hostname(即 FQDN),找來的名字很多時候也不太可靠,那段訊息就是那個意思。

    沒大問題的,很正常。

    Mister Bijou 是英文人, 請以英文作答, 麻煩你了~ :)

  • mk writes:
    September 26th, 2006 at 7:58 pm

    Alright then, I’ll try my best.

    DNS (Domain Name Service) is the way computer on the Internet associates domain name (like sidekick.myblog.hk) with IP address (202.134.73.45) as computer only understands the latter. I guess the rDNS in the traceroute output stands for reverse DNS, which find out the domain name with the given IP. Since not all machines have FQDN, the domain name lookup sometimes will have “fake” outcomes.

    This occurs quite often and it’s completely normal.
