Troubleshoot adblock script

[bazzly]

I was wondering if someone could give me a hand...

I have modified the script for "How to Remove Advertisements with Pixelserv on DD-WRT" And solved a lot of the errors. However I still do not have it functioning correctly.

When the script runs at reboot I get locked out of the WebIF

This is the output at boot

The script is attached.. Any ideas??

This part in the log has me wondering...
pixelserv[665]: Abort: Address already in use

That script will probably require a few changes to work under Asuswrt-merlin. For instance I see in your log that the script is trying to modify the dnsmasq settings through nvram - unlike DD-WRT, we do not store config stuff into nvram. You will have to use a custom config file instead (See the Github Wiki for the details).

However it's restarting dnsmasq will also be totally different between Asuswrt and DD-WRT. Best would probably be to signal dnsmasq telling it to reload its config. Otherwise, kill it, and run "dnsmasq --log-async".

Thanks for the info.. I'm going into unfamiliar Territory for myself..I was gonna bang away at this but dont have a lot of time to mess with it, so I'll chip away at it here and there.

On a side note, as nice as this would be to have this running right now I may give Privoxy a go... and return to the script at some point..

Thanks again

 

[bazzly]

Looks like I'm back to the script lol... Privoxy is not the solution I'm looking for.

Looks like I have a bit of learning to do... Could you point me to the area you think I should look at in the Github Wiki, I took a look, but perhaps I'm looking at the wrong stuff...

I think it would be in this bit of code..

So did anyone get the ad blocking working in the wiki? (I spent hours trying to get it to work with complete fail.)

Anyone want to try and help me get this working..?

I can post what I have changed so far...

On a side note... In the script I have a line "nvram get dnsmasq_options > /tmp/dns-options.tmp"
I know " > /tmp/dns-options.tmp" part is fine... How do I go about the first part? nvram get dnsmasq_options... Should it be something like..

/jffs/configs/dnsmasq.conf.add get dnsmasq_options > /tmp/dns-options.tmp

I think If I get that section working... it may jut work...(Until I find something else broken..lol)

 

[bazzly]

So I gave /jffs/configs/dnsmasq.conf.add a go and that does not see to work...

ad_blocker_script: Injecting the DNSMasq /jffs/configs/dnsmasq.conf.add options with the dynamic block lists
ad_blocker_script: Did not find DNSMsaq options in /jffs/configs/dnsmasq.conf.add and adding them now
ad_blocker_script: Added options to /jffs/configs/dnsmasq.conf.add DNSMasq options
ad_blocker_script: Checking if the personal list is a file
cat: can't open '/tmp/dnsmasq.conf': No such file or directory

I look in the dnsmasq.conf.add and it has nothing it it.

Where is the dnsmasq.conf? Should I be placing this in tmp?
Looks like grep doesnt want to work now... hmm
Attached is the full output, if anyone can give me a clue.

Thanks

 

[bazzly]

Is there anyone in this forum, that would like to help me with this? If not please let me know, and I can try to look else where.. Thanks.

Hi,

I can help re the pixelserv bit, dd-wrt web gui hogs all router ips with the web port - that's why the script moves the router ip off port 80, but it inserts an iptables redirect so that accessing the router ip on port 80 gets redirected to new web interface port 81.

Tomatousb httpd code was modified so that it only listens on router ip port 80, so pixelserv can also use port 80 on a secondary ip.

I don't know what restrictions there are on rmerlin/asuswrt router gui, but presumably it doesn't use those dd-wrt nvram vars to change the port, and then pixelserv can't start start its listener.

An alternative would be to start pixelserv listening on the different port/ secondary ip (and divert ads to it), I used this mode for testing but its not usually compiled in. By the way v19 had some issues, latest is V30 (posted on linksysinfo site).

Re dnsmasq, there is a major potential issue - if the config file (autoparsed from internet blocklists) has an error dnsmsaq dies, the tomato adblock script tries to detect this and deinstalls), not sure about the dd-wrt one. Breaking router dns service makes you very unpopular with your users!

Tomato adblock script kills main router dnsmasq instance and starts its own, an alternative would be to tell dnsmasq via custom script to look in a custom folder - and just delete the folder contents and reload dnsmasq to escape.

This thread has the relevant one line mod to tomato httpd

http://www.linksysinfo.org/index.php?threads/thoughts-on-httpd.31863/

I think this is the relevant line in asuswrt which makes its web gui listen on any router IP and http_port

https://github.com/RMerl/asuswrt-merlin/blob/master/release/src/router/httpd/httpd.c#L278

Wow.. Thanks for the insight... Perhaps I'm a bit over my head then... hmm

Not having a working Adblock on this router make me dislike using this setup very much, and may be reverting back to DDWRT (linksys e4200).
I so want this to work, but it's been a fight.

So with that being said...not sure where I would even start on this. (but I'd like too).

Once again, Thanks for the info... I didnt think anyone was going to reply at this point.

I will attempt to do a little reading when I have a few.

Thanks
