my idea was to check if there is a .add file check if that add file has a entry for privacy filter then if it hasnt add it, in addition i wanted the script if it has a .add file check if the conf has loaded the privacy filter if not add it

think this is a secure way of doing it.

Your script in its present version checks to see if the .add file is there.... and if it isn't then check to see if it has an entry for privacy-filter?... if the .add file doesn't exist then no point trying to grep it.

So a new revision is up

Changes:
  • Added Requirement for entware since it now needs the package hostip to look up ip from dns
  • Rewrite for blocking domains.
  • A new blocklist for privacy
Note: if you get this [name does not exist] when running privacy block then its perfectly fine its just hostip messages if the dns is not working.
 
ok from the weeds and bushes, is there a step by step on how to do this to a router. where to place files how to execute etc? totally new to this but familiar with bat files and such. I looked at the other scripts you had also and just cannot grasp where to place as my ac56r under merlin does not have the dirs mentioned in the scripts and if I make them and place the .sh set to execute it never goes and even if I telnet in and launch it does nothing. is there a kindergarten class somewhere for this?
thanks
 
well yeah

https://github.com/RMerl/asuswrt-merlin/wiki/Entware

you need to install entware in order to use this particular script so begin with that.

And if you need support on that start a new thread after you installed entware you just place that script at /jffs/script/firewall-start and another script at where ever you want preferable /opt/var/cache/privacy-filter/privacy-filter.list and then make /jffs/script/firewall-start executable

this all takes basic linux knowledge and the wiki is always a good place for info along with this forum.
 
thanks for the info.hate to admit I use to maintain aix boxes so some what have a feel for it.
will go for it and thanks for the info.

I updated to the latest version as well as the new blocklist. Unfortunately, one or more of the google.com hosts in the blocklist result in Gmail no longer being able to authenticate, occurring on multiple Android devices:

Code: 
googleadservices.com
www.google-analytics.com
google-analytics.com
ssl.google-analytics.com

I temporarily removed all four hosts, and Gmail works again.

Has anyone else experienced this?
 
nope, but leave em out if they cause an issue for you

note: removed em so i dont have to give support if they can cause a problem, its good enough blocking telemetry and shodan.io and chinese collection servers.

plus its easy enough for adding more dnses to block if anyone wants to block more.
 
@swetoast. Hmm the requirement for this is Entware? As you probably know from my other thread, I did this without Entware or installing any thirdparty program.
 
im working on making it without entware but this revision uses the package hostip to resolve dns to ip, im looking for a way to not use that package unless entware is already install.. so to summarize im working on it :)
 
Oh Okay. Well I'm not using the latest revision, I'm using the one before that, so I guess Entware doesn't apply to me then :)
 
exactly and again the goal is to have it working without entware but its a challange cause i want to resolve the ips from the dns before the block since some of the domain doesnt have static ips
 
well i made something that kinda works but there is an issue

Code: 
for i in `cat $path/privacy-filter.list`; do nslookup $i | tail -3 | grep -oE "$regexp" >> $path/privacy_block.pre; done

the issue is that it lets LAN IP into the mix and thats a deal breaker for me, so if anyone got some sort of solution beside scrubbing the blocklist for LAN IP then please suggest something.

Code: 
for i in `cat $path/privacy-filter.list`; do traceroute $i | head -1 | grep -oE "$regexp" >> $path/privacy_block.pre; done

same issue with this line, so far hostip package is the most secure way of doing this.

bumped it to rev6 with initial way to do it without entware when we find a secure way to do it

I have rebooted but nothing on privacy list is blocked i can still ping all of them. I apologise in advance if i'm being thick, my only experience is following guide for disable win 10 tracking, which used to work and now doesn't.
 
you have a broken script at the end there is a double command

Code: 
run_ipset
exit $?
}

run_ipset
exit $?
should just be

Code: 
run_ipset
exit $?

ohh and rebooting resets your firewall until the script runs again.
 
too check if its working or not just type

Code: 
iptables -vnL FORWARD

should read out something like

Code: 
 pkts bytes target     prot opt in     out     source               destination         
  425 20088 REJECT     all  --  *      *       0.0.0.0/0            0.0.0.0/0            match-set privacy-filter src,dst reject-with icmp-port-unreachable
 
Thanks for pointing out my inability to copy/paste :p

iptables -vnL FORWARD

Windows 10 doesnt talk all the time to its telemetry servers not do you get hit by shodan scanners
