Избавился от ro. Файл exports редактировать не умею, поэтому через веб морду.

Code:

/tmp/mnt/disc0_5/ 192.168.1.1/24(rw,no_root_squash)

Все вроде правильно.. Путь указан верно, инче бы не работало. Айпи правильно, пробовал менять. rw - избавился от ошибки ro. Теперь при копировании ошибка Permission denied. Насколько понимаю, это ошибка доступа или прав... Параметр no_root_squash должен по идее это исправлять, но не исправляет... Я уже хз что делать
