# Interact with `rtscan`
|
|
|
|
`resctl.py` can be used to interact with `rtscan` kernel module via ioctl calls to `/dev/res`. `rtscan.ko` is the original kernel module from Red Star OS 3.0 Desktop.
|
|
|
|
*Note*: On Red Star 3.0 this needs to be executed with root privileges.
|
|
|
|
## Usage Examples
|
|
|
|
### Disable/Enable `rtscan`
|
|
|
|
```
|
|
# python resctl.py disable
|
|
```
|
|
```
|
|
# python resctl.py enable
|
|
```
|
|
|
|
### Protect/Hide a File
|
|
|
|
The following example adds a new file extension to the list of scanned extensions and a new file to the protected and hidden files:
|
|
|
|
```
|
|
# cat /tmp/secret.32c3
|
|
Kim loves Katy
|
|
# python resctl.py setsign .32c3
|
|
# python resctl.py protect /tmp/secret.32c3
|
|
# python resctl.py hide /tmp/secret.32c3
|
|
# cat /tmp/secret.32c3
|
|
cat: /tmp/secret.32c3: Operation not permitted
|
|
```
|
|
|
|
Disabling `rtscan` will make the file readable again:
|
|
|
|
```
|
|
# python resctl.py disable
|
|
# cat /tmp/secret.32c3
|
|
Kim loves Katy
|
|
```
|
|
|
|
*Note*: The default list of extensions added by `opprc`:
