Squid 3.3.4 package for pfsense with ssl filtering

quetzalcoatl

I hope the file libgssapi.so.10 will be added to the next pfsense snapshots or within the next release of squid3.3

I have been trying all evening to get this file into that /usr/local/lib folder
but i did not succeed.

How do i copy or move a file from the internet to a certain folder inside pfsense?
Using the GUI i can upload a file but i don't know how to place it in /usr/local/lib

using console/ssh

cd /usr/local/lib
fetch url_for_libs

Download all libs from my ldd folder.

Thanks to you now I'm a little less ignorant about pfsense and squid! :P

I did copy several files from http://e-sac.siteseguro.ws/pfsense/8/amd64/All/ldd/ to /usr/local/lib

until when i do squid -NsXY it doesn't ask me any more for missing files but now squid still service doesn't start and when i do squid -NsXY the shell shows me a bunch of:
"Acl.cc(353) ~ACL: ACL::~ACL: ´"

and i don't know how to see above these lines because there are too many.

I don't know how to scroll text lines inside the shell.
(tons of ignorance here! sorry)

Hi marcelloc,

I tried it with my normal configuration (pfSense -> DG -> Squid3 -> Internet) and couldn't get it to work.

DG on pfSense:8080 with Squid as parent
Squid3 on 127.0.0.1:3128

Check if squid is running, on log you sent I can see only warnings.

squid -NsXY on console can show you squid startup error or /var/squid/logs/cache.log

Hi, I am having problems using squid 3.3
I can not start the service ..
Returns the following error ..

I've been trying to get my "Squid3-dev"+"Squidguard" config running (no ssl & no antivirus active, not yet anyway)

Copied the libs and chmod 755, used WinSCP.

First warning:

php: /pkg_edit.php: The command '/usr/pbi/squid-amd64/sbin/squid -f /usr/pbi/squid-amd64/etc/squid/squid.conf' returned exit code '1', the output was '2013/05/14 19:27:02| Warning: empty ACL: acl localnet src FATAL: Bungled squid.conf line 33: offline_mode offcache_swap_low 90 Squid Cache (Version 3.3.4): Terminated abnormally.

Squid complains "localnet" was not set correctly. I changed the code to work.
I hardcoded my localnet into "squid.inc" so the squid.conf line would read "acl localnet src 192.168.0.1/24"
So that was a quick and very dirty temporary fix. (but hey it works…)


	if ($settings['allow_interface'] == 'on') {
		$src = '';
		foreach ($real_ifaces as $iface) {
			list($ip, $mask) = $iface;
			$ip = long2ip(ip2long($ip) & ip2long($mask));
			$mask = 32-log((ip2long($mask) ^ ip2long('255.255.255.255'))+1,2);
			$src .= " $ip/$mask";
		}
		$conf .= "# Allow local network(s) on interface(s)\n";
		$conf .= "acl localnet src 192.168.0.0/24\n";
		$valid_acls[] = 'localnet';

Hmmm.. "offline_mode offcache_swap_low 90" not good…
So checked "squid.inc" again, added extra linefeed between "offline_mode" and "EOD".

cache_mem $memory_cache_size MB
maximum_object_size_in_memory {$max_objsize_in_mem} KB
memory_replacement_policy {$memory_policy}
cache_replacement_policy {$cache_policy}
$disk_cache_opts
minimum_object_size {$min_objsize} KB
maximum_object_size {$max_objsize}
offline_mode {$offline_mode}

EOD;

Changes for "squidguard_configurator.inc" (replaced redirector commands, for squid 3.3 compatibility)

# ------------------------------------------------------------------------------
# squid config options
# ------------------------------------------------------------------------------
define('REDIRECTOR_OPTIONS_REM',   '# squidGuard options');
define('REDIRECTOR_PROGRAM_OPT',   'url_rewrite_program');
define('REDIRECT_BYPASS_OPT',      'url_rewrite_bypass');
define('REDIRECT_CHILDREN_OPT',    'url_rewrite_children');
define('REDIRECTOR_PROCESS_COUNT', '5'); # redirector processes count will started

Clear old settings from the "Proxy server" page, then save on the "proxy filter" page again so the new redirector commands are used.

I've pushed a fix for some of these issues

on 2.0.x, if you got squid running but no port listening, you may try squid 3.3.4 from my repo compiled without ipv6.

amd64
http://e-sac.siteseguro.ws/packages/amd64/8/All/squid-3.3.4.tbz

i386
http://e-sac.siteseguro.ws/packages/8/All/squid-3.3.4.tbz

Some lib replacements may require a reboot to avoid squid crashes.

athurdent

Great package, thank you!
On my i386 test KVM I had to copy over the libs and also reinstall squid3-dev afterwards. It would not start because of:

squid[88922]: execvp failed: (2) No such file or directory

Now it's working and I am testing it.

I'm confused, is it working or not ???

Nope, wasn't running. I tried again and got:

Noticeable points:

I had all my subnets on the ACL allow list (don't remember why)
I had pfsense.org and pfsense.com in ACL allow lists, from problems I had once accessing new package information
I didn't uninstall Squid3 first. But when I noticed that I still had it, I tried to uninstall it and reinstall Squid3-dev and it still didn't work
I get multiple dansguardian[23423]: Error connecting to proxy messages in system.log and no internet connectivity at all
no transparent http or https checked, Squid3-dev listening on localhost:3128 only, NAT rules to redirect 80 to DG, then DG has Squid as parent.

Maybe Squid3-dev works best without DG underneath?

uninstall both and then reinstall squid3-dev.

I've pushed yesterday some fixes to conf generator.

I think it's better to test squid itself and then go to dansguardian integration.

Leave localhost unchecked, it's automatically inserted when using transparent mode. I'll include this warning on gui to prevent some errors.

Sorry for not being clearer. After copying the libs it would not start until I reinstalled it. Just wanted to let others know that maybe a reinstall is needed after putting the libs in place.
It works fine now and I have to dig a little further into ssl filtering ;)

@wheelz:

How are the certificates set up? I know the pfsense box should act as a certificate authority and all the clients must trust it. So is the CA cert automatically generated and how do

Default web configurator certificate can be used.

I deleted my original default certificates some time ago and set up my own CA using pfSense. What kind of certificate do I need to create for SSL interception to work? I tried generating a CA certificate signed by my CA but Squid does not like it.
I always get

squid: No valid signing SSL certificate configured for http_port 192.168.x.4:3128

also tried using a server certificate, does not work either, same error. Any hints for me?

marcelloc

@athurdent:

I'm using a server ceritificate signed by created ca.

webconfigurator in some cases may work too.

Check on cache.log if squid is not crashing while trying to intercept ssl.

I've found another missing file:

ERROR: auth_param basic program /usr/local/libexec/squid/msnt_auth: (2) No such file or directory
FATAL: auth_param basic program /usr/local/libexec/squid/msnt_auth: (2) No such file or directory Squid Cache (Version 3.3.4)

(there IS a file called basic_msnt_auth)

I get this error, if I try to activate the NT Domain authentication. By the way, there is another helper called ntlm_smb_lm_auth. Wouldn't that be the better choice for windows?

The only tested NTLM authentication for pfsense that I am aware of is outlined in my thread: http://forum.pfsense.org/index.php/topic,58700.0.html. That was using an earlier version of squid though. If you find other auth plugins that work or expand on this, I'd really like to know the details of it. If so, please post it in that thread to put it all in one place for everyone's benefit.

Fehler20

It seems to be that there was some renaming done. The LDAP plugin is broken, too (I havn't tested RADIUS).
@wheelz: You are correct :), I've tried ntlm_smb_lm_auth today and it does not seem to work either with IE and FF. There are some strings exchanged between the Domain Controller and squid, but SSO with NTLM does not work neither entering the creditals manually.

Btw could you add another option to the webinterface: I gives the ability to add custom caching rules.

/usr/local/pkg/squid.inc line 983

//custom Options
$conf.=sq_text_area_decode($settings['custcache']);
$conf.='
';

and

/usr/local/pkg/squid_cache.xml line 138ff.

Edit: I have found a new problem/mistake. The cache function only works if I manually add this custom option:

cache allow ALL

Maybe this has to be added to the default configuration.

Can't it be done on custom options?

I'll check it.

Yes, but it is a little bit confusing, if there is an option. It causes every following configuration change to fail because the config file is corrupted.
