Privoxy + opera get rid of ads

After the acquisition of unlimited and the inclusion of images (yes, the small joys of a provincial student), the question of choosing an advertisement re-cutter arose. Here is a small digression: I hate advertising. No, everyone on the Internet hates advertising, but I have at least 3 compelling reasons to hate it:
1) Bright, checkered, often interferes with surfing
2) My old comp computer hardly turns colorful flushes. Father's computer and even more so.
3) It hurts unpleasantly, showing the mother a book on the vareznik, contemplating jumping bare ass and stuff.
Both I and my father used the opera and were not going to change it for anything, so the problem of choosing a cutter was quite acute. For some reason, I didn’t want to use Block CSS in the opera, but now I don’t want to. After a short googling, my choice fell on privoxy. This is a powerful advertiser that works on the side of the router (in my case, because I have a home local router on the slak, my computer and my father) as a proxy server. This approach in filtering ads suited me, because it was easy to prescribe a proxy, if you want to disable it, and so on.
In this article I will describe my steps for installing and configuring privoxy on my home server under skackware 13.
To begin with, we had to create a user and a group privoxy. I leave the creation method of your choice.
I decided to install the program using src2pkg . And then it turned out that without a few gestures can not do.
An example installation looks like this:
mkdir /tmp/privoxy
cd /tmp/privoxy
wget 'http://heanet.dl.sourceforge.net/project/ijbswa/Sources/3.0.16%20(stable)/privoxy-3.0.16-stable-src.tar.gz'
Next, create two scripts in the same folder:
privoxy.src2pkg:
#!/bin/bash
## src2pkg script for: privoxy

SOURCE_NAME='privoxy-3.0.16-stable-src.tar.gz'

VERSION='3.0.16' # Use ALT_VERSION to override guessed value
# ARCH=''
# BUILD='1'
# PRE_FIX='usr'

# from the privoxy.SlackBuild:
PRIVOXY_USER=${PRIVOXY_USER:-privoxy}
PRIVOXY_GROUP=${PRIVOXY_GROUP:-privoxy}
if ! grep -q ^$PRIVOXY_GROUP: /etc/group 2>/dev/null ; then
echo " Error: PRIVOXY group ($PRIVOXY_GROUP) doesn't exist."
echo " Try creating one with: groupadd -g 206 $PRIVOXY_GROUP"
exit 1
fi
if ! grep -q ^$PRIVOXY_USER: /etc/passwd 2>/dev/null ; then
echo " Error: PRIVOXY user ($PRIVOXY_USER) doesn't exist."
echo " Try creating one with: useradd -u 206 -g $PRIVOXY_GROUP -d /dev/null -s /bin/false $PRIVOXY_USER"
exit 1
fi

# Any extra options go here:

--localstatedir=/var \
--docdir=$docdir/$NAME-$VERSION \
--with-docbook=no \
--with-user=$PRIVOXY_USER \
--with-group=$PRIVOXY_GROUP"

fi

# If there's no existing log file, move this one over;
# otherwise, kill the new one
if [ ! -e var/log/privoxy/logfile ]; then
mv var/log/privoxy/logfile.new var/log/privoxy/logfile
else
rm -f var/log/privoxy/logfile.new
fi

if ! grep -q ^privoxy: /etc/group 2>/dev/null ; then
echo " Error: PRIVOXY group 'privoxy' doesn't exist."
echo " Creating one with: groupadd -g 206 privoxy"
groupadd -g 206 @PRIVOXY_GROU@
fi

if ! grep -q ^privoxy: /etc/passwd 2>/dev/null ; then
echo " Error: PRIVOXY user 'privoxy' doesn't exist."
echo " Try creating one with: useradd -u 206 -g privoxy -d /dev/null -s /bin/false privoxy"
exit 1
fi

if ! [ -x etc/rc.d/rc.privoxy ]; then
echo " etc/rc.d/rc.privoxy must be set executable to enable privoxy at boot-time:"
echo " chmod 755 /etc/rc.d/rc.privoxy"
fi

For the scripts, we say thanks to the developer src2pkg Gilbert Ashley.
We put the right to perform. After that, we collect the package and put the privoxy team
src2pkg -X -C -I
The program was installed successfully. It took me a minimal config change:
1. commented listen-address 127.0.0.1:8118
2. listen-address 192.168.0.1:8118
3. permit-access 192.168.0.0/24
Next, you need to change the /etc/rc.d/rc.privoxy file

PRIVOXY_USER="privoxy"
PRIVOXY_GROUP="privoxy"

Now you can start privoxy for the first time:
root@ironnet:/tmp/privoxy# /etc/rc.d/rc.privoxy start
Starting privoxy: OK

Now all I have to do is register in the proxy browser 192.168.0.1:8118

Unfortunately, after some time, it turned out that the built-in filter does not cope with filtering. After a brief googling, a python script was borrowed from here to automatically generate rules based on the blocklist from the marine.
I changed it a little bit by adding another blocklist for parsing. Total left this:
#!/usr/bin/perl

We save this miracle under the name adblock2privoxy.pl in the / etc / privoxy directory, issue the execution rights. Further extract from the readme to this script:

adblock2privoxy.pl Perl AdBlock Privoxy.

(Linux):

1. .
2. ($cfg, $tmp)
3. .
4. Privoxy "actionsfile":
: actionsfile user.action
: actionsfile adblock.action
5. ( sudo) cron'
6. Privoxy

What we are doing.

Well, for complete happiness we add crowns:

40 4 * * * /etc/privoxy/adblock2privoxy.pl
42 4 * * * /etc/rc.d/rc.privoxy restart

Total: we get a very smart, easily customizable, regularly updated and most importantly correctly and logically working advertizer for the opera. Isn't it a beauty?

Well, as a final touch, I will provide you with a couple of screenshots.
