ipWhitelist HowTo

krisalexroberts · Aug 27, 2017, 1:36 PM

The reason why “/24” works
A couple different threads state to add /24 to the end of the IP address. (I’ve put a couple of those up before doing some research too). While this will indeed allow your network devices access to your magic mirror, it will also allow any device with an IPv4 based address access to your mirror (obviously your router would need to be configured to allow this).
This “/24” in IPv6 CIDR allows 20,282,409,603,651,670,423,947,251,286,016 different IP addresses access. (IPv4’s total addresses are 4,294,967,296).

More information
If you’d like to learn more or have different sub-netting needs, I found this page useful.

I don’t ageee with that. 192.167.1.0/24 is everything in the 192.168.1.x range, nothing more nothing less. If it allows more than this is a massive flaw/security risk.

If you want to allow your own subnet then just look at your subnet mask and use google to get the CIDR

I agree that /24 is 255.255.255.0 or 192.268.x.0 to 192.168.x.255

That’s why these issues are making me crazy aka can’t figure them out.

FOUND A WAY TO RESOLVE THIS!

Add

cat /etc/modprobe.d/ipv6.conf 
# Don't load ipv6 by default
alias net-pf-10 off
# uncommented
alias ipv6 off
# added
options ipv6 disable_ipv6=1
# this is needed for not loading ipv6 driver 
blacklist ipv6

to turn off all IPv6 on the Raspi.
Than edit all the IPv6 out of your config file.

 },
        ipWhitelist: [
                "192.168.0.92",
                "192.168.0.1/24",
                "127.0.0.1"

I still have the .92 in there from testing. It is not needed.

did a sudo reboot just for safe measure and now it all seems to be working as intended. No real idea what the actual issue was…but it is resolved. FINALLY! :)

Maybe I have missed this from someone else, but one important thing about the whitelisting message:

“This device is not allowed to access your mirror.
Please check your config.js or config.js.sample to change this.”

The EXACT SAME message appears (in my case) if the config.js has syntax errors. Locally your mirror will tell you that there is no config file or just give you a black screen, but if you try to reach it from outside through a browser (Firefox and Chrome in my case) with a broken config.js, you will get the whitelisting message above.

So, before trying to get your ipWhitelist in the right shape, make sure you have no other syntax errors with the mirror, e.g. using

npm run config:check

If you had some and had them corrected, be safe and restart the mirror.
Below you can see the example in my case.

I just updated to the latest version of MM and am having White-list issues once again. I am using my exact same config.js file that was allowing any incoming connection. prior to the upgrade. I have attempted to debug but am not seeing any connection refusals in the mm-out-0.log. I have tried various fixes from posts on this forum, including disabling IPv6. I have confirmed my CIDR criteria using https://www.ipaddressguide.com/cidr#range attempting different variations to get anything to pass through with no luck.

I use MMM-syslog as a notification system from various sources and am basically in the dark now. Is there anyone having similar issues with the latest version, any luck on how to fix?

@Oss

Have you tried this at the beginning of your config?:

var config = {
	address: "0.0.0.0", 
	port: 8080,
	ipWhitelist: [],

Hello All. I recently upgraded my magic mirror and no matter what changes I make I can’t get ipwhitelist to work. I have searched the forums and every suggestion I have come across hasn’t rectified my issue. I had it working just fine prior to the upgrade. Any suggestions would be greatly appreciated.

Thanks,
Illskool
