Sarg package for pfsense

wdowney

I had the same problem as LoZio. To get mine to work I did the following -

de-selected all of the options on the general tab and saved it
forced an update on the schedule tab
re-selected the options on the general tab and saved it
forced an update on the schedule tab

This caused the index.html file to be generated in my /usr/local/sarg-reports folder. Up until this point everything else was working except for the index.html file.

Hi all,

I've just published sarg package for pfsense with squid,squidguard and dansguardian log Analysis as well real time report tab.

Squidguard functions are under devel yet but squid and dansguardians(as well as I tested) are working.

After almost everything done, I found an old sarg package published on forum by joaohf and merged some function calls from this old thread.

Another good point is that sarg is able to forward logs via email, so I'm planning to include it for nanobsd installs.

have fun and feedback! :)

Thanks a lot!

Hi,

I would like to use sarg package to get a better overview of the blocked sites from squidguard.
I do not have logging enabled on squid - just on squidguard to watch the blocked sites.

In my company it is not allowed to log accessed sites. The log view of squidguard is not the best I think and so I would like to use squidguard.

On the sarg "general" tab I selected "squidguard" and so options on the multiple-choise lists. When saving the settings I got an error on the top right corner that the squid/access.log was not found.

I took a look at the sarg.inc and I think the problem could be somewhere on line 230. But I am not sure. I added a "break;" but without luck.

So my questions are:
Is it possible to use sarg to just "analyse" the blocked.log file of squidguard but no other log files ?

Any help would be appreciated :-)

Hi Nachtfalke,

I've enabled squidguard config options on gui, but I do not use squidguard. take a look on sarg config options and check manually how it should be configured to work with squidguard. I'll push a fix if you find a way to get it working only with squidguard reports.

The missing break was intentional as it requires squid to work.

I changed the following code on sarg.inc starting on line 227:
From:


		case 'squidguard':
			$squidguard_conf='squidguard_conf '.$sarg_proxy['squidguard_config'];
			$redirector_log_format='redirector_log_format #year#-#mon#-#day# #hour# #tmp#/#list#/#tmp#/#tmp#/#url#/#tmp# #ip#/#tmp# #user# #end#';
			#Leve this case without break to include squid log file on squidguard option

To:


		case 'squidguard':
			$access_log= $sarg_proxy['squidguard_block_log'];
			$squidguard_conf='squidguard_conf '.$sarg_proxy['squidguard_config'];
			$redirector_log_format='redirector_log_format #year#-#mon#-#day# #hour# #tmp#/#list#/#tmp#/#tmp#/#url#/#tmp# #ip#/#tmp# #user# #end#';
			#Leve this case without break to include squid log file on squidguard option
		break;

Now I got this error on system log:

Not sure what that means ?

PS: Why is xmlrpc sync starting but I did not enable that !?

Maybe a too long line

@Nachtfalke:

Maybe a print message before the if :)

move

from line 441 to 445 after

2.0.1 Release x86 w/ latest Sarg (which is working pretty well)

Was a solution found for the LDAP issue? I've read the thread a few times and didn't see anything definitive.

I've tried every GUI config possible, forcing updates over and over, tweaking the conf file, reinstalled Sarg, restarted pfSense. etc.

I ran the packet sniffer on the LAN adapter for hours and ran another one on the AD LDAP server.
No port 389 traffic from the pfSense box at all.
From what I see, LDAP is dead.

I'll keep trying but I'm not sure where to look next.

Tried again with a blank block.log file from squidguard with a short entry.
SARG does not generate me any reports on that file.

The access.log from squid is working fine - but as I said I do not want that - or better I am not allowed to do that ;-)

So my conclusion is:
The sarg.inc file needs modification to find the block.log file from squidguard. In the sarg.inc the squidguard_block_log variable is created but it will not be used in further code.

BUT it seems that SARG does not know how to interpret the squidguard log files - even if it has some additional options for that. Google couldn't help me until now. Will do further searches.

Not yet. It looks like a missing LDAP dependence on compile arts. :(

I agree. But It's hard to test without using squidgurd. I did not found a working setup on Google too.

This is the answer on my question. I will please him to show me his config for sarg and the versions of squidguard and sarg he is using.


Hi Nachtfalke

> 1.) Is it possible to analyze/read squidguard's blocked websites log with
> SARG ?

Yes, it definitly is. They will be shown as blocked sites in SARG. I
am using this exact setup and its working fine. If you like, I can
send you my config file, alongside with the version numbers of the
programms.

OK. Thank you. If time and attention-span allows I'll poke around a bit.

For now I'll try the Users Association option for manual IP/Name mapping.

I have an related Idea:
I'm fantasizing about a pfSense WINS-like feature that would store+associate Username/Machine Name/IP+MAC Addy
In theory it'd pull info from LDAP, pfSense DHCP & DNS or possibly local LAN DHCP & DNS.

The idea is it'd be a single database that packages could use to pull User Info.
Another option -> Pushing data from this db into whatever table a package is using to store it's LDAP/User info.

Is this worth posting as a forum suggestion? I can't tell.

Nachtfalke

I got this as answer from the mailing list - not sure if this will help me. Need some time to check what he said and the corresponding .conf files.


Hi

Attached you will find my configs, they are from an ubuntu 10.04
system, running squid 2.7Stable7, squidguard 1.4 and sarg 2.3.

Several pitfalls I remember:
- pay special attention to the HTMLOUT of sarg-reports.conf
- pay special attention to the stopped.log directives in squidguard.conf
- triple check that the squid and squidguard log files are readable
and the HTMLOUT is writable by sarg
- there is a known bug in squidguard concerning some escape chars in
urls that cause the squidguard log file to become malformatted. Sarg
dies when this happens. Therefore I am using a self patched version of
squidguard: http://51762846.de.strato-hosting.eu/bene/public/squidguard/

Try running sarg-reports as root in from the console: It should start
with something like

/usr/sbin/sarg-reports daily
SARG: Init
SARG: Loading configuration from /etc/sarg/sarg.conf
SARG: Loading exclude host file from: /etc/sarg/exclude_hosts
SARG: Loading exclude file from: /etc/sarg/exclude_users
SARG: Parameters:
SARG:           Hostname or IP address (-a) =
SARG:                    Useragent log (-b) =
SARG:                     Exclude file (-c) = /etc/sarg/exclude_hosts

Hope this helps

Ok, I did some further tests. the sarg.inc is - as far as I tested it - correct.

But for squidguard it means:
If logging in squid is disabled then SARG cannot display only the blocked URL squidguard reported.
So in my situation I cannot use SARG because I am not allowed to have the squid access.log file. :(

I am still working on recovering from a disaster caused by this package. I figured I'd drop a note here as a possible warning for anyone that is using this package. It may be possible that this was a user issue, rather then the fault of the package.

I sadly can't provide many details at this point, if I can come across anything I will follow back up. Either case:

I just lost my pfsense box due to massive corruption caused by (indirectly?) Sarg. I had Sarg running for ~2 month, maybe a bit more. A few days ago I noticed issues with networking and started digging into it. I found pfsense to be unresponsive. I rebooted it and started getting a lot of wonderful errors..

Either case, somehow Sarg had created enough files to run me out of inodes. It was somewhere near 60GB's of data, and 9.7M (yes, MILLION) inodes in use.
(this is for a 3 user network)

I believe I was using the stock out of the box configuration on it. Sadly, it was a pain to get setup in the first place, that once it did start working I never did go back and look at it again.

Current sarg version has compress report files and remove reports older then x days.

Sarg reports use a lot of inodes.
On my setup, I've installed a second disc with zfs just for report files. On zfs disc, I got 30million inodes.

What changes you did to get squidguard working? can you push it ot github?

Try to point sarg to an access.empty.log file on squid config at sarg.inc. this may solve your problem.

I tried that with an access.log file which just contains some entries but this didn't help me on the SARG reports. It doesn't show me blocked entries newer than the access.log file entries.

So there isn't anything I could push on github ;-)

In general it is working with your config with squidguard but you need the access.log from squid. If this file isn't present and actual you cannot generate reports.

Is dansguardian doing that without squid access.log file ?
