Country Block
-
pfBlocker 0.1.2 is out.
Now with widget.
-
I we can't figure out how to increase the table size limits for large lists like level1 then perhaps we can break the lists into multiple tables.
Example:
table limit will be 10,000 entries. More entries will go into another table. So if Level1 has 35,000 lines the we will have 3 tables-
pfblocker - 10000 lines
-
pfblocker1 - 10000 lines
-
pfblocker2 - 10000 lines
-
pfblocker3 - 5000 lines
What do you think? I hope we can find a way to increase the memory limit.
-
-
Could be a solution for this problem.
I'm still looking for a way to do it without multiple tables or file hacks.
Does it happens on x64 versions with for example 4g ram?
And thanks for widget clue. :)
-
I've included all countries and levels 1,2,3 plus some ads, virus, etc
total:449418 Networks
no erros.
my system is x64 with more then 4g ram.
-
The problem is it isn't a RAM limitation. It's a memory max allocation variable that is small to begin with. So no matter how much RAM you have on x86 or x64 you will get that error once that limitation is hit.
This is why it is a problem. We need to be able to raise that limit other wise the functionality will be greatly limited, leaving users to fall back on IP-Blocklist.
-
449418 Networks seems very small for level1, 2, and 3 with others. Are you sure those lists were all successful?
-
Could we include in GUI an option to increase this value and advise users that its unsupported?
EDIT:
wc -l in level files downloaded in cidr from fetch:
245749 level1
85703 level2
18753 level3

kk. We could give the users the option. It would just be inserting that text every time that file gets recreated. I've already done most of the work in IP-Blocklist and Countryblock.
/usr/local/pkg/pf/pf-blocker.sh
#!/bin/sh export t=`grep -n 'User Aliases' /tmp/rules.debug |grep -o '[0-9]\{1,2\}'` t=$(($t+'1')) #Insert table-entry limit /usr/bin/sed -i -e '/900000/d' /tmp/rules.debug while read line do a=$(($a+1)); #echo $a; if [ "$a" = "$t" ]; then echo "" >> /tmp/rules.debug.tmp echo "set limit table-entries 900000" >> /tmp/rules.debug fi echo $line >> /tmp/rules.debug done < "/tmp/rules.debug"This code isn't tested but it's on the right track. We will have to have it check if the user has enabled this feature. I do this is IP-Blocklist and countryblock. Basically if the user enables it the package will create a file. If it's disabled the the file will be deleted. The script above will check if the file exists```
if [ -e FILE ] ....code here -
ok, I think its good enough to prevent errors until some 'core developer' could help us.
I'll try to put it in php way for most code compatibility.
The last thing to finish pfBlocker is cron package integration.
-
Cron for the updates?
-
use cron package instead of editing /etc/cront for lists updates…

Great work so far on the pfblocker package. I currently have a problem with it. I had countryblock installed and working previously. I removed that package and then installed the pfblocker package. The widget says that it is blocking networks but it comes up with a fail to load list message in the syslog.

Post here the countries you selected.
I will check the script.
-
I tired various countries, I get the same result when I select whitelist. I get the same result with all the countries. I have selected one from top spammers and one from south america. I also noticed that when i select one country from a tab then i can not unselect it. I can only select other ones. Using Chrome.

I found the error.
It's fixed now.

tommyboy,
Instead of editing /tmp/rules.debug, i will 'patch' filter.inc file with table-entries when clients choose to increase table.
I will also write some code to alert user when table gets larger then default limit.
-
That sounds like a good solution. We can use sed to insert the line to 'patch' and remove the line to 'unpatch'
-
I don't believe this:
Look what i found in filter.inc after coding everything…
set limit table-entries {$config['system']['maximumtableentries']}
it was all time in front of our noses :D
I'll fix the code and relase a new version..
-
PfBlocker 0.1.3 is out.
Main improvement:
Check network list size before applying rules. If lists are bigger then table size, pfBlocker sends a warning to user and suggest new value for table size.
-
tommyboy,
I've started a new topip for pfBlocker, if you don't mind.
