Sarg package for pfsense

LinuxTracker · Dec 5, 2012, 4:46 PM

@LinuxTracker:

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

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

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.

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
SARG:                  Date from-until (-d) = 04/12/2012-04/12/2012
SARG:    Email address to send reports (-e) =
SARG:                      Config file (-f) = /etc/sarg/sarg.conf
SARG:                      Date format (-g) = Europe (dd/mm/yyyy)
SARG:                        IP report (-i) = No
SARG:                        Input log (-l) = /var/log/squid/access.log
SARG:                   Redirector log (-L) = /var/log/squid/stopped.log
SARG:               Resolve IP Address (-n) = No
SARG:                       Output dir (-o) = /var/www/squid-reports/Daily/
SARG: Use Ip Address instead of userid (-p) = No
SARG:                    Accessed site (-s) =
SARG:                             Time (-t) =
SARG:                             User (-u) =
SARG:                    Temporary dir (-w) = /tmp
SARG:                   Debug messages (-x) = Yes
SARG:                 Process messages (-z) = No

If something goes wrong and you don't know what to make of the error
message, just post it here.

Hope this helps

Greetings

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 ?

I have also run into the error that others are seeing:

Error: Could not find report index file.
Check and save sarg settings and try to force sarg schedule.

Here's what I've done.

Totally uninstalled Sarg pkg.
Used "find" command to locate and remove every directory or file referencing sarg in the name.
Upgraded to absolute latest (2nd release from today) pfsense package.
Rebooted.
Reinstalled Sarg.
Selected all report options and report types on the Sarg page in pfsense.
Hit Save.
Set up a 1h schedule and saved it.
Hit "force update" under the schedule.

ls -al /usr/local/sarg-reports/
total 4
drwxr-xr-x 2 root wheel 512 Dec 10 21:19 .
drwxr-xr-x 19 root wheel 512 Dec 10 21:19 ..

No index file(s) of any kind appear there.

This is a drag. What does it take to get a simple package to just install and work the first time?

Does anyone have a solution on how to fix this manually?

Thanks in advance for any help you can offer.

ps - I did find this in system.log:
Dec 10 21:20:24 gw php: /pkg_edit.php: [sarg] sarg_xmlrpc_sync.php is starting.
Dec 10 21:20:32 gw php: /pkg_edit.php: Sarg: force refresh now with args, compress() and none action after sarg finish.

marcelloc · Dec 11, 2012, 3:13 AM

Caldwell, there is no bug on sarg package for squid and dansguardian logs.

just take a a look on forum for a working config that I'm using and check your squid access log config.

marcelloc · Dec 11, 2012, 3:23 AM

Nachtfalke,

Maybe a grep on squid log file for denied entries????

This way there will be only denied access to report.

Did you tried to select only denied sites on reports to generate?

Nachtfalke · Dec 11, 2012, 12:34 PM

@marcelloc:

Nachtfalke,

You think of a possibility that a script could do the grep on the access.log, just save the denied entries in a new file and delete the original one ?
Didn't try that but could be a possibility.

@marcelloc:

Did you tried to select only denied sites on reports to generate?

Not sure if I did that. But I saw all sites so I suppose that I didn't try that. Perhaps I can try this if I find some spare time. I uninstalled SARG some days ago.

Hi, I just did a fresh installation of pfSense, then squid 2.7.9 pkg v.4.3.1 and after that Sarg 2.3.2 pkg v.0.6.1.

Running a simple report generation with "force update now" gives this output:

php: /pkg_edit.php: The command '/usr/local/bin/sarg ' returned exit code '1', the output was 'SARG: Records in file: 13455, reading: 0.00%^MSARG: Records in file: 5000, reading: 37.16%^MSARG: Records in file: 10000, reading: 74.32%^MSARG: cannot open /usr/local/sarg-reports/2013/01/18-19/sarg-date for writing SARG:: No such file or directory SARG: Records in file: 13455, reading: 100.00%'

Sarg created a folder at that time: /usr/local/sarg-reports/2013/01/18-19.5 with the content
drwxr-xr-x 2 root wheel 114176 Jan 19 16:00 192_168_24_10

-rw-r--r-- 1 root wheel 4893 Jan 19 16:00 topsites.html.gz

So I do not understand what to with "MSARG: cannot open /usr/local/sarg-reports/2013/01/18-19/sarg-date for writing SARG:: No such file or directory"

Can someone help me?

marcelloc · Jan 19, 2013, 4:05 PM

What sarg options did you selected on GUI? Did you tried to remove this report before running sarg again?

bernie156 · Jan 19, 2013, 10:47 PM

I only selected Report Options "Convert to IP address" and "Top Users" and "Top Sites" on the General Tab. The scheduled report has no Sarg args set.

No, I didn't try to remove a report. Tab "View Report" says always
Error: Could not find report index file.
Check and save sarg settings and try to force sarg schedule.

marcelloc · Jan 20, 2013, 2:52 AM

Check config options. One you will need is create index file

bernie156 · Jan 20, 2013, 10:46 AM

Selected all options wich were default "(yes)". And - as expected - got: "Error: Could not find report index file. Check and save sarg settings and try to force sarg schedule."

As you can see in my first post, the index.html is there but cannot be found.

Today /usr/local/sarg-reports/18Jan2013-20Jan2013 contains

I did a fresh install of pfSense, squid 3 and Sarg, selected all Sarg default options and it works. Thanks for your effort anyway.

KeltecRFB · Jan 29, 2013, 2:43 PM

Raising a Necro-Thread instead of creating a new one.

Is there way to configure Sarg to show denied access reporting and what Proxy\Dans acl triggered it? Can that be done in the GUI or is it in CLI only?

Thanks!

@KeltecRFB:

Sarg only understands squid log format, so I think it sarg is not able to log what ACL denied a url.

Do you have a sarg config that does it?
