port چیست؟

در ساده ترين تعريف، محلی است که داده‌ها وارد یا خارج می‌شوند. در مبحث هک معمولا با پورت‌های نرم‌افزاری سروکار داريم که به هر کدام عددی نسبت می‌دهيم. اين اعداد بين 1 و 65535 هستند. معمولا به يک سری از پورت‌ها کار خاصی را نسبت می‌دهند و بقيه به‌صورت پيش‌فرض برای استفاده شما هستند. پورت‌های که فعال هستند، هرکدام توسط يک نرم‌افزار خاص مديريت می‌شوند.مثلا پورت 25 برای ارسال ایمیل است ، بنابراين بايد توسط يک نرم‌افزار اين کار انجام شود و اين نرم‌افزار بر روی پورت 25 منتظر (فال‌گوش) می‌ماند. اينجا ممکن است شخصی از فلان نرم‌افزار و ديگری از بهمان نرم‌افزار استفاده کند ولی به‌هر حال پورت 25 هميشه برای ارسال است در پایین لیستی از مهمترین پورت ها و کاربردشان را می بینید

  • First of all I want to say great blog! I had a quick question in which I'd like to ask if you do not mind. I was curious to find out how you center yourself and clear your thoughts before writing. I have had a hard time clearing my mind in getting my thoughts out. I do take pleasure in writing however it just seems like the first 10 to 15 minutes tend to be wasted simply just trying to figure out how to begin. Any recommendations or hints? Thank you!

  • You actually make it seem so easy with your presentation but I find this topic to be actually something that I think I would never understand. It seems too complicated and very broad for me. I am looking forward for your next post, I will try to get the hang of it!
