آشنایی با کتابخانه قدرتمند PCap.Net - بخش هشتم (پایانی)

ارسال پاکت ها

هرچند که نام Pcap.Net هدف آن را ضبط پاکت ها معرفی می کند سایر ویژگی های سودمند برای شبکه سازی اولیه نیز در آن تدارک دیده شده است.از جمله آنها وجود مجموعه ی کاملی از توابع برای ارسال پاکت هاست.

نکته: کتابخانه اصلی Libpcap امکانی برای ارسال پاکت ها تدارک ندیده است.از اینرو تمامی توابع نشان داده شده در اینجا از ملحقات Pcap.Net مبتنی بر Wincap است و تحت Unix کار نخواهد کرد.

ارسال بسته تکی با استفاده از SendPacket()

ساده ترین روش ارسال پاکت ها در کد بعدی نشان داده شده است.پس از باز کردن آداپتور SendPacket() برای ارسال پاکت دست ساز فراخوانی شده است.SendPacket() پاکت شامل داده را به عنوان پارامتر می گیرد تا آن را ارسال کند.توجه داشته باشید پاکت به همان شکلی که هست به شبکه ارسال می شود ، بدون هیچ گونه دستکاری ای.این بدین معنا است که برنامه مجبور است برای ارسال چیزی معنی دار سرآیند های پروتکل را به صورت صحیح و به ترتیب ایجاد کند.

کد از تابع SendPacket() برای ارسال ۱۰۰ پاکت ICMP Echo (Ping) به مقصد های متفاوت IPv4 با ID های متفاوت IPv4، شماره ترتیب های متفاوت ICMP و شناسه های متفاوت ICMP استفاده می کند.این کار با استفاده از نمونه سازی از PacketBuilder به همراه Ethernet ، IPv4 و لایه های ICMP Echo و تغییر مشخصه های لایه ها برای هرپاکت انجام می شود.در ادامه کد از تابع SendPacket() برای ارسال پاکت های متفاوت استفاده می شود.ایجاد هریک از این پاکت ها در متد های متفاوت Build…Packet() انجام می شود.این مثال می تواند یک دید کلی از پاکت های متفاوتی که می توانید بوسیله Pcap.Net ایجاد کنید را در اختیار شما قرار می دهد.
