ارتباط از راه سی‌اس‌اچ تفاوت برجسته‌ای در سیستم‌های گوناگون نداره

کد: (اوبونتو) [انتخاب]

$ ssh {userID}@{hostname}
$ # for example
$ ssh b12345@laurel.kudpc.kyoto-u.ac.jp
Enter passphrase for key '/home/$USER/.ssh/id_rsa': Entering your passphrase(not displayed).

از کجا بدونم userID کدومه.

[藤沼]

باید از مدیر سیستم و کسی که سرور رو راه‌اندازی کرده بپرسید.

[nanophysic]

ipهمون id هستش 

[Nelliel]

ipهمون id هستش 

ID=Idenity
IP=Internet protocol

الان چه ربطی داره ای دی و ای پی؟؟؟
مگه قرار نیست یه سرور secure sell قراره راه بندازید ؟؟؟؟
این بخش ای دی و ای پی برام نافهومه

[nanophysic]

قراره وصل بشم به یه سرور دیگه.از طریق سیستم عامل خودم که لینوکس با توزیع ابونتو هستش به یه ابر رایانه بروش ssh
 من ip اونو دارم.از پوتی هم استفاده کردم ولی فقط یه صفحه مشکی باز میشه

تو انجمن هم سرچ کردی دوست عزیز؟؟؟

یادمه چندوقت پیش یکی دیگه همین مشکل را داشت با پاتی منم تو تاپیک شرکت کردم ولی یادم نیست مشکلش با پاتی حل شد یا نه کلمه ی putty را سرچ کن اولین لینک هست اونم براش فقط یه صفحه ی خاکستری میومد

[nanophysic]

 از طریق ترمینال ک دستور ssh رو میزنم.بعد وارد کردن پسورد وپیغام میده ارتباط بسته

کد: [انتخاب]

Connection closed by 176.100.55.84

از طریق پوتی هم این ارور رو میده                                                                  Acsses denied

[藤沼]

از آپشن v- استفاده کنید تا جزئیات بیشتری نشون داده بشه. مراحل زیر رو انجام بدید:

کد: [انتخاب]

sudo service ssh start
ssh -v username@hostname

یک نقطه در اول نام‌کاربریتون وجود داره آیا عمدیه؟! ضمناً نباید از ایمیلتون استفاده کنید باید بجاش «lenovo» رو بکار ببرید.

بله عمدی هستش.؟آخه خود سرور ایمیلو بعنوان شناسه کاربری اعلام کرده وطبق دستورات ک بهم داده بودن  اونو باید بعنوان یوزر نیم میزاشتم قبل از@
