BGP4 Case Studies/Tutorial by Sam Halabi - Cisco Systems

A Canadian firm unveiled what it called "the world's first commercially viable quantum computer." D-Wave Systems, Inc., "The Quantum Computing Company," during a much ballyhooed rollout at the Computer History Museum in Mountain View, Calif., hailed the new device as a big step toward the age of quantum computing, decades earlier than scheduled.

But experts say the announcement may be a bit—er—premature. Even if the computer were to work as advertised, it still would be nearly 1,000 times too small to solve problems that stump ordinary computers. Moreover, researchers do not know whether it will work at bigger sizes.

قسمت اول : راه اندازی IPTABLES برای PAT
یکی دو ماه پیش مطلبی در خصوص PAT و NAT در روترهای Cisco داشتیم و ادبیات هر دو را به تفضیل و با مثال و Sample Configuration توضیح دادیم ، اگر در مفاهیم PAT و NAT سئوالی دارید ، لطفا به مطالب قبلی (در همین صفحه و یا در آرشیو ماهیانه) مراجعه فرمایید.

در این مثال لینوکس در لبه شبکه قرار دارد و می خواهد از طریق iptables برای شبکه داخل شرکت PAT کند. لطفا به نکات زیر توجه فرمایید :

1. اینترنت ADSL شما می بایست از نوع Bridge باشد که متاسفانه فقط برخی از شرکت ها این سرویس را ارائه می کنند !
2. نسخه لینوکس Fedora 4 می باشد.
3. از نسخه iptables موجود در Fedora 4 استفاده شده است.
4. به Case Sensitive بودن دستورات توجه کنید!

 برای این کار کافی است iptables را start کنید :

etc/init.d/iptables start

با این کار عملا iptables می گوید هر ترافیکی که خواست از اینترفیس eth1 خارج شود را ابتدا IP آن را به IP اینترفیس eth1 ترجمه کن و با عملیات PAT ارسال کن.

در قسمت دوم نحوه Server Publishing را در ادامه همین سناریو توضیح خواهم داد.
نظرات شما برای ما مهم و جهت دهنده است ، لطفا در مورد تاپیک ها ما را از نظرات خود محروم نفرمایید.
موفق و پیروز باشید.
