On sudo side there is no issue with your version but I think you did an oversize cleaning on /dev folder
- Code: Select all
sh: can't create /dev/null: Permission denied
As the firmware uses often this node for wasting the standard output with sudo, the shell commands run by php fail...
So try to create again the node
- Code: Select all
mknod /dev/null c 1 3
chmod 666 /dev/null
reboot the NAS and try to change some settings on the web-interface
and post also the content of /dev
- Code: Select all
ls -a /dev
