Hi,
i tried to run from ssh and i found out that (some) SARG:TAG: make troubles…
after set a comment # in front of a lot of tags it works now...

have now only this TAG's

SARG: TAG: access_log /var/squid/logs/access.log
SARG: TAG: output_dir /usr/local/sarg-reports
SARG: TAG: resolve_ip no
SARG: TAG: user_ip no
SARG: TAG: index no
SARG: TAG: overwrite_report no
SARG: TAG: privacy no
SARG: TAG: dansguardian_conf
SARG: TAG: denied_report_limit 0
SARG: TAG: sorttable /sarg_sorttable.js
SARG: Deleting temporary directory "/tmp/sarg"

(change something in the sarg config –> restore defect config )

It's realy hard to find out who is (are) the fault one.

But run from web i get still the "Cannot set the locale LC_ALL..." error

Hi,
months ago I configured sarg on a test fw proxy server with squid+squidguard.
I remember "denied sites" were "highlighted" on userid reports by the string "DENIED" placed on right side of denied url, outside the last column(%TIME).

Now I cannot reproduce this feature on my production proxy.
I activated every log option on squid and squidguard: I can see denied sites on squidguard log, but no "DENIED" string appear on sarg report.
Moreover I can't find any "Denied sites" report despite I have enabled that option on "report to generate" section of general tab.

Do you have any idea/same problem?
Thank you in advance

While using squidguard, all errors pages will be logged there.
Are your report set to squid or squidguard logs?

Squidguard.

Meanwhile I answered to my question: DENIED "message" appear on sarg report only if the blocked site is in squid blacklist (Access control tab).
I forgot/I did not notice that. Sorry….

It'd be nice if the same sarg feature was reproduced for squidguard blocked sites...
But if i do not get wrong sarg is a closed project....

You can have squidguard denied sites by squidguard by changing squidguard report and squid acl.

Squid3-dev package has this feature, take a look and see how to include it on your current config.

Thanks Marcello!

Finally I get Squid3-dev, SquidGuard-squid3 and sarge to work:
1) after many install/uninstall squidguard started to work only after I selected the transparent proxy interface (not present in the previous squid installed version)
2) On sarge I had to change the squidguard.conf path to /usr/pbi/squidguard-squid3-amd64/etc/squidguard/squidguard.conf on /usr/pbi/sarg-amd64/etc/sarg/sarge.conf

Now I was trying to understand how to get "denied" sites… sorry but what do you mean by "by changing squidguard report and squid acl"? I can't find any "help" on forum..
Thank you in advance.

Take a look on squid3-dev general tab

Follow instructions on field "Log denied pages by squidguard"

Hi there !
I have a problem with my Sarg 2.3.6_2 pkg v.0.6.3
Because of my network had many VLANS so i NAT them with a Internet IP, and I put the Pfsensen in edge of the Internet gateway router (next to)
In my Sarg's report , it can't be show the UserID mapping with IP , because these ips were NAT
So , How can i modify the output of report , can its show only UserID field ? guide me ?

Thanks so much !

Do you have the usernames logged on you proxy log?

steel_dragon

Do you have the usernames logged on you proxy log?

NO, there are no Usernames in proxy log, they appear with "-" instead of "Username"

Here is my log in /var/squid/logs/access.log

such as :

There is nothing sarg can do if squid logs does not have the client ip.

Look for logging X_forwarded_for info on squid.
This topic may help http://forum.pfsense.org/index.php/topic,54227.msg322323.html#msg322323

Yes, I have looked for many other way, but not found something good !
Here is my network :

MultiVLAN <–-> Layer3Switch <----> FirewallCisco <----> InternetGW_router <-----> Pfsense (squid+sarg+lightsquid) <----> Internet

Should I change my position of Proxy ?? Where do I put ?

Thanks so much !

Enable nat ony on pfsense. Configure all other devices as routers

Hi

I am running pfsense 2.1 AMD64 with squid2.7 and squidguard with latest version of SARG.
I have logging enabled for squid and I can see the accessed sites in access.log

Further I have enabled logging on squidguard to log blocked sites.

Unfortunately I only get the access sites on SARG and the DENIED sites which I blacklisted on squid GUI. But I do not get the websites blocked by squidguard.

Here is the debug output of SARG:

This is the file of squidguard which contains 5 blocked websites with no special chars or long URLs.


SARG: Reading redirector log file /var/squidGuard/log/block.log.0

I configured that path in sarg.conf

So my problem is why do I get this output:


SARG: (info) Redirector report not generated because it is empty

It shouldn't be empty - it contains blocked websites. I checked the redirector_log_format option on sarg.conf but it was correctly configured for SQUIDGUARD. I changed it to the other possibility just for testing but without luck.

I know that I posted in this thread some months ago with a similar problem but I don't know anymore what to do to get this fixed.

I would appreciate any help!

@Nachtfalke:

Try this way:

On squid2 custom options include


acl sglog url_regex -i .*sgrd=ACCESSDENIED;http_access deny sglog;

Edit sgerror.php and include this code

$sge_prefix=(preg_match("/\?/",$cl['u'])?"&":"?");
$str[] = '<iframe src="'.$cl['u'].$sge_prefix.'sgrd=ACCESSDENIED" width="1" height="1"></iframe>';

This way, every time squidguard shows access denied error, it forces client to send the blocked url to squid again to be blocked and logged by sglog acl.

Nachtfalke

Works great! 8)

Have an additional question:

SARG logs the denied pages when I open a website in my browser like www.my-website.com and this domain is in my blocklist. Then I got the custom squidguard access denied page with your "pixel" which sends this page to squid.

So if there are any other applications which use http traffic which is blocked by squidguard then this page will not be logged.

Is this correct?
Is this because these apps do not display the blocked page with the "pixel"?

Just want to make sure I understand what's happening. So I would check SARG denied pages to check which pages the user directly browsed and squidguard log will tell my everything which is blocked - no matter if via browser or other app.

THANK YOU! :-)

marcelloc

If the app does not open/execute the error page, then it will not be logged.

Can you simulate it?

Nachtfalke

@marcelloc:

If the app does not open/execute the error page, then it will not be logged.

Can you simulate it?

Yes, it is as you said. SquidGuard internal Log page shows blocks on Computers where nobody is logged in and browsing the web via webbrwoser. SARG does not log this.

If I open a webbrowser and go to a webpage which is blocked then I got the denied page and SARG is logging this.

Another question on shedules:
Yesterday - 29. November - I did some "Force Update Now" and always got an updated report. The "Creation date" was always updated on the "View reports" pages.

After doing some tests I created a shedule which runs once a day "1d" with no extra arguments.
Today - 30. November - I looked at the "View reports" page and could only see the report from yesterday (29. November). I clicked on "Force update now" and sarg created me a new report for today but did NOT update the report from yesterday. Is this normal!?!

I deleted all reports from /usr/local/sarg-reports and forced again an update and only got a report from the 30. November but not from yesterday. I then used custom arduments to get reports from yesterday and so on but did not get the report from yesterday.

Please help! ;)

What I would like to have:
A shedule that will create me a report beginning a 0:00am until 11:59pm for every day.

–- edit ---

I think I found an solution:
I disabled log rotation on squid.
I created one shedule with frequency "1d" and logrotate on sarg
I created a second shedule with frequency "1h" and no logrotate.

This will update my daily report every hour and will rotate then every day - probably at midnight.

Question:
Where is the difference between:
logrotate
proxy daemon restart
logrotate and restart proxy daemon
?

--- edit2 ---

Was it your intention to only sync "General" and "Users" tab? I would think it would be usefull to sync "Shedule", too.

I hat a look at this part in sarg.inc:


        /* xml will hold the sections to sync */
        $xml = array();
        $xml['sarg'] = $config['installedpackages']['sarg'];
        $xml['sarguser'] = $config['installedpackages']['sarguser'];
        /* assemble xmlrpc payload */
        $params = array(
                XML_RPC_encode($password),
                XML_RPC_encode($xml)
        );

Maybe I just forgot to include schedule array on sync.
