سلام. به همه
چند وقتی هست(چند ماه بعد از زمان انتشار اوبونتو ۱۵/۱۰ تا الان و بعد از بروز رسانی) یعنی از هنگامی که دانشگاهمون دسترسی به اینترنتش با vpn pptp امکان پذیر شد، من با pptp به مشکل خوردم.
مشکل از این قرار هست که بعد از گذشت زمانی پس از اتصال، pptp به صورت ناگهانی شروع به مصرف بالای پردازنده میکنه و بعد از مدتی هم قطع میشه. به نظر میاد با سرعت بالایی(20M/s) هم ارسال داده میکنه! حالا دقیق نمیدونم مشکل از سرویس ارايه دهنده vpn دانشگاه هست یا از pptp
apport به من با عنوان "pptp crashed with sigsegv" گزارش میده. نظر شما چیست؟
خروجی لاگ کرنل به صورت زیر هست - در زمان اتصال و قطع شدن:
