Squid 3.3.4 package for pfsense with ssl filtering
-
It would not start because of:
squid[88922]: execvp failed: (2) No such file or directoryNow it's working and I am testing it.
I'm confused, is it working or not ???

DG on pfSense:8080 with Squid as parent
Squid3 on 127.0.0.1:3128Check 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
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 ;) -
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 getsquid: No valid signing SSL certificate configured for http_port 192.168.x.4:3128also tried using a server certificate, does not work either, same error. Any hints for me?
-

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.

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.

Maybe this has to be added to the default configuration.

Can't it be done on custom options?

I'll check it.
-
Can't it be done on custom options?
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.

custom_options need one cmd per line instead of old ";" from squid2.
Is this the way you are doing?

I just noticed that if you use an authentcation method from the authentication tab this causes the following error:
php: /pkg_edit.php: The command '/usr/local/sbin/squid -k reconfigure -f /usr/local/etc/squid/squid.conf' returned exit code '1', the output was '2013/05/16 19:07:32| 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): Terminated abnormally.

I'm fixing it and checking other config changes. I'll push new gui version today.

pkg version 2.1.1 is out.
main changes
-
Fixed auth plugins filenames
-
Included more ssl_crt checks
-
Included custom refresh_pattern field for dynamic content on cache tab
-
Included missing cache allow all on squid.inc(this may fix no cache hits issue with dynamic content enabled.)
-
-
•Included custom refresh_pattern field for dynamic content on cache tab
Little Problem here: you have to insert a new line after the custom caching options. If not the configuration becomes corrupted.
Besides this caching (of dynamic content) works for me now. Thank you! -

Test inserting an extra <enter>on your custom options.</enter>

On the i-cap for AV feature… If I am already using Dan's Guardian with the ClamAV options, would there be any reason to switch to squid using i-cap when it is working? Or is that mainly geared for people who are using squid by itself?

No need to move. dansguardian talks to clamav via socket.

pkg version 2.1.2 is out.
main change
-
change ssl filtering cert combo from server-cert to ca-cert
-
Insert an additional <enter>after cache pattern custom field to avoid config crashes</enter>
This version has ssl_filtering working really nice on pfsense 2.1. :)
On 2.0.x enable ipv6 on system->advanced to squid be able to listen on configured port.
EDIT
Using squid from my repo, ssl_filtering is working fine on 2.0.x too ;D
