-cpu model name : Intel(R) Core(TM)2 Duo CPU E7300 @ 2.66GHz
-ram : 2x2048mb ddr2 800mhz
-gpu : gigabyte radeon r9 270(2048mb gddr5) costs 341 BGN with VAT included
-power supply : corsair cx600 costs 145 BGN with VAT included
The linux distribution which is used here i BAMT
The mining performance approximately is 400kh/s.

500 OOPS: vsftpd: refusing to run with writable root inside chroot()
During the setting up vsftpd(2.3.5-3) daemon in Debian Wheezy, I found the following error 500 OOPS: vsftpd: refusing to run with writable root inside chroot() when you try to open ftp connection to the server.This appears when chroot_local_user=YES option is enabled in /etc/vsftpd.conf.Many people had the same problem.This is BUG which is already reported.We can fix this problem with additional patch.
