Dansguardian package for 2.0

wheelz

Hmm.. yea, just to confirm from another system, I tried setting 512M and then 1024M (rebooted after each) and I still got this on save:

Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 42 bytes) in /usr/local/pkg/dansguardian.inc on line 1138

Hi,

i have resolved our issue for the php and blacklist problem.

I deleted /usr/local/pkg/blacklist.tgz and everything else regarding blacklist.

I then deinstalled dansguardian and reinstalled it.

That has it solved.

I have another problem :o

Since a few days internal dns resolving doesn't work anymore.

I can resolve forum.pfsense.org with not problems but, for example, not http://wpad.

That causes my automatic proxy configuration to stop and our clients have no internet access anymore.

If i bypass the proxy, it works like before.

Any hints in the right direction?

Cheers.

Do you have at least one of your DNS server entries on the box pointing to your local machine. Also is your DHCP server assign you local machine as a DNS server? If not that is most likely your problem.

You did?… that sounds really familiar:

@elemay:

and also it doesn't continue installing the package after downloading blacklists file.

Not sure what the issue here was but I was able to get it to install by first deleting the blacklists file and then doing an uninstall and reinstall of dansguardian and squid3 (I use squid3 in my case).

It's all good, just had to harrass you a little. ;) Could have saved you some trial and error.

Hi,

I'm installing several new VSATs in the near future and would like to use pfSense with DansGuardian. I would also like to have the time groups features of SquidGuard. Is it possible to run both of these packages on pfSense? I tried installing them both but once I did DG didn't work anymore. I'm guessing it was a configuration issue. If I can run both at the same time, how should they be configured to pass traffic properly between them?

My ultimate goal is to have the filtering of DG and be able to block certain websites/file types/mime types during certain times of the day. An example would be to block Facebook from 7am until 5pm and all video files from 5am until midnight.

Thanks for any help.

Hi marcelloc,

I increased memory to 384MB as you suggested, seems working, will report back if any issues.

I have another issue here. MS Outlook isn't working behind pfsense. I have setup wpad and tried manually setting proxy in ie also.

I have squid3 in non-transparent mode with DG.

Any suggestions..?

You mean owa or msoutlook communication to exchange server?

aru

I mean outlook pop3 mail fetching. No exchange server. Clients in lan configured pop3 are unable to download. server authentication not happening.

marcelloc

Pop3 is not http. Dansguardian does not affect it.

I did this and I still get

Fatal error: Allowed memory size of 402653184 bytes exhausted (tried to allocate 71 bytes) in /usr/local/pkg/dansguardian.inc on line 1138

. However when I bump it to 512 or higher it goes back to saying my allowed memory size is 134217728…. ???

marcelloc

The hard limit is configured to 512. Try 500.

I'll find the option to increase it and post here.

wheelz

It turns out to be exactly 488 MB is the most I can give it. If I do 489 MB or higher the error seems to indicate that it didn't actually do it and it is still set to 128MB. I still get the memory errors with 488 MB as well.

wheelz

Any ideas on this? I guess I'm kind of stuck in my configuration until this is resolved.

The other value to increase is
suhosin.memory_limit = 512435456 on /etc/rc.php_ini_setup

Until I find a way to reduce dansguardian memory load during config save, you may need to increase these values.

I was able to setup the groups feature, and I'm glad to report it's working as expected, except for one problem: every time I make a change to dansguardian the content of the "ipgroups" file is wiped out. any suggestions

Dear Community,

I am trying to setup dansguardian with groups / user authentification.

Dansguardian already works but I'm not really sure about how to set it up including authentification.
When I enable auth at the squid proxy and directly connect the browser to it I get the auth prompt and I am able to login and use the proxy.
The problem is now when I switch back the browser proxy setting to the dansguardian 8080 port I can browse the web with dansguardian rules active but without any auth prompt. Even when I change the "Auth Plugins" setting under general it stays the same.
Well… am I doing it wrong?
Thx for your help.

There has got to be a memory leak or something to that effect. I found that if you set that value in /etc/rc.php_ini_setup to 2 GB or higher then it doesn't take it and you go back to 128 MB. So I set it to a max of 1.99 GB. I then kept bumping up the other values listed earlier and eventually got to 2000 MB (not quite 2GB) and I still get this almost all of the time:

Fatal error: Allowed memory size of 2097152000 bytes exhausted (tried to allocate 136184137 bytes) in /usr/local/pkg/dansguardian.inc on line 1150

I used top and watched the php processes. I didn't even make any changes to any settings, just picked an ACL in the DG config and hit save. I saw 2 php processes consume 100% of CPU1 and CPU2 and memory go up to close to 2GB and that's when I get the error. It took a good 30 seconds to a minute afterwards for it to drop off. The very first time I hit save it did not error, but even after a reboot for some reason it has done it ever since. Any ideas? This seems like more than just it using more memory as I can't see how saving some config files would eat up this much resources.

marcelloc

fetch this dansguardian.inc file from my repo, it has a lot o debug

http://e-sac.siteseguro.ws/packages/dansguardian/dansguardian.inc.txt

download it and save on /usr/local/pkg/dansguardian.inc

this inc file will stop process to show memory usage, if you want to test a full save config, remove the exit at line 1210.

on my testes, memory usage stays below 128Mb.
