You can get the values easily but can't set them without root access because the files are read-only (
rw-r-r) for "others".
Get the values
- Use D. Gibbs's answer to setup ADB.
Launch Terminal/cmd in PC and enter:
find /proc/sys/net/ -type f | while read -r file; do echo $file $(cat $file); done
find will find the files under the location
/proc/sys/net/. Tweak the location if the need arises.
while read will read each line of the previous output as a file,
do will allow execution of tasks (
echo "filename" and show its value using
done to complete the task.
- Sources: 1, 2.
Snippet of output:
You may save the output into a file by using
> <FILENAME> at the end of the step 2's last command.
- Some files won't be saved or shown because of file permissions. In that case, root the device and repeat the aforesaid steps using
su after adb
Set the values
Now that you've a table of file -> value, you can change the value using
echo, provided that you've root access.
In the terminal, enter:
echo <VALUE> > <FILE_PATH>
<VALUE> with the value you want to set and
<FILEPATH> with the path of the file. E.g.
echo 46 > proc/sys/net/core/dev_weight
You can apply the steps in a terminal app on Android as well. Just make minor changes relevant to the environment, like
> <FILENAME> in find command, and not using
