Is the squidguard package stable at the moment…..

heiko

Sorry…
if i create an ACL and delete this item, so the ACL list is empty the following error occurs....

Warning: Invalid argument supplied for foreach() in /usr/local/pkg/squidguard.inc on line 414 Warning: Cannot modify header information - headers already sent by (output started at /usr/local/pkg/squidguard.inc:414) in /usr/local/www/pkg.php on line 87

Another blacklist update?

Hello dvserg,
for me it blocks nothing with the default configuration, maybe my fault…
Do you have a small tutorial for starting.

Warning: Invalid argument supplied for foreach()

Add one entry on Destination page (i will insert checking for empty listing)

Quick start
http://diskatel.narod.ru/sgquick.htm

Probably You have error in config - in this situation SG generated small block config
Check log on thirts page (general) for found error messages.

I took a look at you tutorial, but my webgui-log shows errors and says "starts with default". I see the ACL errors, but i didn´t have ACL´s in my config. I have downloaded the shallalist and the logs says that the db is OK. At the End i click on the Apply button and then this happens.

Here my log…

Hello,
last Test:

First of all, i think the acl page have problems. If i delete ACL Lines, the Line shows a blank config. If i restarted squidguard errors appears.

- Source not found….

Now i edit the acl line and filling a few words in it and checked disable. After that, i have made a restart at the generel page with clicing the apply button.

For me it looks Ok, but also nothing content was blocked...

I don´t know where my config is buggy. Maybe, take a look at the screenshots
I don´t use the transparent proxy feature but local user authentication.

I'm getting something similar…all was well until recently..... After awhile the error stops showing and Squidguard is apparently running, but no content gets blocked. If I re-install I get the same issue.

Warning: implode(): Bad arguments. in /usr/local/pkg/squidguard_configurator.inc on line 367 Warning: Cannot modify header information - headers already sent by (output started at /usr/local/pkg/squidguard_configurator.inc:367) in /usr/local/www/pkg_edit.php on line 35

dvserg

Thanks. I will test this too.

aaron

I occasionally get the implode type of error when I've deleted a destination group or blacklist group and haven't gone through all the ACLs to update them. Perhaps it's a similar problem?

Also, heiko, I am using squidGuard in a production environment and am happy with the results.

ColdFusion

This happens on fresh install with no destination groups deleted. It happens after uploading Blacklist or hitting apply changes. Then error goes away and no content is blocked.

dvserg

Thanks for previous bug-report's.
I fix it (may be >:( ) and update sources.
If possible check this bugs now.

Also i remake ACL-ordering code for more stable.

ColdFusion

Seems to be working now. Since the last few changes, I can no longer access the blocked log report tab….I get block_log report disabled. The other thing I'm trying to figure out is how to whitelist certain sites that are in the blacklist...

dvserg

I can no longer access the blocked log report tab....I get block_log report disabled.

I disable this function. After short time i return to renew this code with more quick algorithm (i houpe).
If you need this now - you can modify squidGuard.php:

comment with '#' line 710

#                                $slog .= 'block_log report disabled';

delete '/' and '/' symbols in 711 and 747 lines.

ps this actual on today time; in next time code can changed.

heiko

Sorry dvserg, i wouldn´t set off an avalanche with my question.
Greetings

ColdFusion

I finally figured out how to whitelist a url that's blacklisted. In destination tab I created a whitelist and blacklist. When I put a url that I want to add to the blacklist it worked. However when I put a url that I want to whitelist it still didn't work. I looked in the squidgaurd config and found this:
dest whitelist {
domainlist whitelist/domains
urllist whitelist/urls
log block.log
}

dest Blacklist {
domainlist Blacklist/domains
urllist Blacklist/urls
redirect http://192.168.0.1/sgerror.php?url=http://www.yahoo.com&a=%a&n=%n&i=%i&s=%s&t=%t&u=%u
log block.log
}

acl {
default {
pass !blk_BL_adv !blk_BL_aggressive !blk_BL_chat !blk_BL_drugs !blk_BL_gamble !blk_BL_hacking !blk_BL_porn !blk_BL_redirector !blk_BL_spyware !blk_BL_tracker !blk_BL_warez whitelist !Blacklist all
redirect http://192.168.0.1/sgerror.php?url=http://www.yahoo.com&a=%a&n=%n&i=%i&s=%s&t=%t&u=%u
}
}

However the my whitelist and blacklist were added to the back of the config. I edited my xml config and replaced it with this:
dest whitelist {
domainlist whitelist/domains
urllist whitelist/urls
log block.log
}

dest Blacklist {
domainlist Blacklist/domains
urllist Blacklist/urls
redirect http://192.168.0.1/sgerror.php?url=http://www.yahoo.com&a=%a&n=%n&i=%i&s=%s&t=%t&u=%u
log block.log
}

acl {
default {
pass whitelist !Blacklist !blk_BL_adv !blk_BL_aggressive !blk_BL_chat !blk_BL_drugs !blk_BL_gamble !blk_BL_hacking !blk_BL_porn !blk_BL_redirector !blk_BL_spyware !blk_BL_tracker !blk_BL_warez all
redirect http://192.168.0.1/sgerror.php?url=http://www.yahoo.com&a=%a&n=%n&i=%i&s=%s&t=%t&u=%u
}
}

I put my whitelist and blacklist in front of the file…..it now works.

dvserg

@ColdFusion:

You wanted say, what SG dest order has important meaning?
I not found information in manuals about this
If you can - please help find it fo me - this is really important.
Thanks.

ColdFusion

Maybe I should clarify. The order seems important. If you look at the example above I just moved the whitelist to the front. The additional blacklist created doesn’t matter the order. I found the info at http://squidguard.shalla.de/Doc/configure.html

Whitelisting

Sometimes there is a demand to allow specific URLs and domains although they are part of the blocklists for a good reason. In this case you want to whitelist these domains and URLs.
Defining a whitelist
dest white {
domainlist white/domains
urllist white/urls
}

acl {
default {
pass white !adv !porn !warez all
redirect http://localhost/block.html
}

}

Basically the whitelist works before the blacklist.

ColdFusion

I guess one would get the same result if you named your whitelist something like AA….first order seems to be ads.....Example AA ads aggressive......

acl {
default {
pass AA !blk_adv !blk_BL_aggressive !blk_BL_chat !blk_BL_drugs !blk_BL_gamble !blk_BL_hacking !blk_BL_porn !blk_BL_redirector !blk_BL_spyware !

didn't try this though but should work.

I had the same problem. I had to reinstall the package xml…then that cleared up the error and everything is working fine.
