ubuntu üzerinde ssh sunucu

ubuntu üzerinde ssh sunucuyu aktif etmek istiyorsanız openssh-server i kurmak yeterli olacaktır.

fcicek@ubuntu:~$ sudo apt-get install openssh-server

sunucunun aktif olduğunun kontrollerini yapalım.

fcicek@ubuntu:~$ ps -aux|grep sshd

debian altında kullanılmayan yapılandırma dosyaları

sisteminiz üzerinden programı kaldırdıktan sonra sistem üzerinde kalan ve kullanılmayan yapılandırma dosyalarını bulmak için

dpkg -l | awk '/^rc/ {print $2}'

kaldırmak için

sudo su
dpkg -l | awk '/^rc/ {print $2}' | xargs dpkg --purge

kullanabilirsiniz.

crossover veya wine da proteusda VGDVC.DLL hatası

linuxde zorunlu olarak bir proteus dosyası açmanız gerektiği durumda wine veya crossover üzerinde poteus kurarak dosyayı açmak istetediğinizde

“Internal Exception: Access violation in module ‘VGDVC.DLL’ [00010C56]”

hatası ie karşılaşmanız çok olasıdır.. bunun için regedit i açarak

HKEY_CURRENT_USER\Software\Labcenter Electronics\Proteus 8 Professional\Default Graphics Mode=1

değeri 1 olarak değiştirmeniz gerekmektedir.
