Saving and loading the wireless mac filter lists

[mightyoakbob]

I've made a lot of progress this morning with working out how to load and save various bits of the nvram settings. I would also like to be able to save load the mac filter list.

I have have discovered that the 2.4 GHz mac filter list can be obtained with this...

nvram get wl0_maclist_x > /mnt/Home/Bob/24maclist.txt

This works EVEN for ME!!

But the 5.0 GHz list seems to be in two variables and these are..

wl1_maclist_x AND wl_maclist_x

Which should I use to restore the settings after a factory reset?

Another question about restoring the data.. I've read and seen two methods of doing this will both work as well as each other?

nvram set varname="'cat /mnt/Home/Bob/filename'"
And
nvram set varname=$(cat /mnt/Home/Bob/filename

Are both of the above the same and is my syntax correct?

Am I correct in thinking I need to use nvram commit with either of them?


Thanks everyone. You can probably see I am at last starting to get to grips with this now. Nearly there at last.


Cheers.

Bob.

I can't specifically answer your questions (I use the first syntax you mention, and decided to save/restore BOTH of those variables), but here is another example of what you're trying to do which may help.

The firmware uses what I call "settings instancing". Basically, the web interface lets you edit the content of wl_xxx. When you save your settings, the web interface writes all its wl_xxx settings to the flash. Then, the router checks if you just edited the 2.4 GHz settings or 5 GHz settings, and it will copy the wl_xxx settings you just saved to either to wl0_xxx (2.4 GHz) or wl1_xxx (5 GHz).

So when settings exist in blah_xxx, blah0_xxx and blah1_xxx form, you only need the numbered instance - the unnumbered one is just a temporary save location used by the web interface.

Instancing is used with wifi (wl_), wan (wan_), OpenVPN (vpn_server_ and vpn_client_), and a few other areas.

Brilliant absolutely brilliant, a complete and full explanation which incredibly I actually understand and can use.

Thanks Merlin you are a star.
