Squid 3.3.4 package for pfsense with ssl filtering

ncolunga

Nice work, it's a great addition to pfsense and works very well. Is this going to be implemented on the squid3 "normal" package too?

marcelloc

squid3-dev will be squid3 when finished.

Hi everyone. I am using Squid3-dev (3.3.8 ) and squidGuard-squid3. Everything is ok in transparent mode on http and https (Thanks to Marcelloc ;) ).
But you said it was possible to use both transparent and authentication with squid3-dev:

@marcelloc:

@wheelz:

Is it possible to run squid as explicit on one interface (like loopback or LAN) and also run it as transparent on a different interface like a guest net at the same time?

On squid3-dev yes ;D

Remember to do not use loopback on any configuration while using transparent mode.

I have tried and it does not work for me: I use 2 interfaces on the same LAN with a different IP address for each one (192.168.1.254 and 192.168.1.253). I have selected the both for "Proxy interface(s)" in "Squid General Settings".
In 'Transparent Proxy Settings" and "SSL man in the middle Filtering", just the 192.168.1.254 is selected. When I use this interface for the web navigation, it is ok, the transparent mode is working.
But if I explicitly use the 192.168.1.253 (not selected in transparent mode), the proxy doesn't ask me for authentication.

These are the squid.conf first lines:

http_port 192.168.1.254:3128 ssl-bump generate-host-certificates=on dynamic_cert_mem_cache_size=10MB cert=/usr/pbi/squid-i386/etc/squid/serverkey.pem capath=/usr/pbi/squid-i386/share/certs/

http_port 192.168.1.253:3128
http_port 127.0.0.1:3128 intercept ssl-bump generate-host-certificates=on dynamic_cert_mem_cache_size=10MB cert=/usr/pbi/squid-i386/etc/squid/serverkey.pem capath=/usr/pbi/squid-i386/share/certs/

https_port 127.0.0.1:3129 intercept ssl-bump generate-host-certificates=on dynamic_cert_mem_cache_size=10MB cert=/usr/pbi/squid-i386/etc/squid/serverkey.pem capath=/usr/pbi/squid-i386/share/certs/

I don't know why the IP is 127.0.0.1 for the "intercept" and not juste the 192.168.1.254, even if I suppose it is normal. Have I to edit manually the squid.conf? Is there someone using both transparent and anthentication on 2 different interfaces? Could someone help me please?

Hope it will be soon release. But last time I roll back from -dev version of Squid. To much problem for the first time using of pfSense.

There is another issue, I am not able to auth through captive portal and provide different acl to various groups. May be I doing something wrong, please post the right procedure to do it.

Thanks in advance

marcelloc

@exograpix:

Did you applied captive portal patch on squid config?

@exograpix:

and provide different acl to various groups.

Are you doing it with custom options?

exograpix

I feel it is sorted now, yes captive portal is set as auth medium in squid, I have now added groups and username in the squidguard group acl, seems to be working.

Another issue is i am not able to configure antivirus with squid3-dev and neither with havp package.

NetWiz

How to check pf operational after squid-dev removal? I also had patches for it and HAVP. I don't see any garbage in webgui, but I see some trash from old package in configs. Now I have one headache - ipcad doesn't report to access.log. If client goes on proxy-port 3128 it's traced in logs. Direct connections - not.

Hi Marcelloc

I just installed a test machine with pFsense 2.1 Release, squid3-dev and squidGuard-squid3.
I can't start squidguard service, but can't find why.

In logs, here is my error message:

pfSense php: /pkg_edit.php: The command '/usr/pbi/squid-amd64/sbin/squid -k reconfigure -f /usr/pbi/squid-amd64/etc/squid/squid.conf' returned exit code '1', the output was 'squid: ERROR: No running copy'

Any Idea ?

Hi,

I have read this thread and several topics/tutorials on the web but I still cant figure out whether Squid3 and especially 3.3.8-dev is able to cach dynamic content.

I understand that 3.3.8-dev has solved an issue on squid3 stable where enabling dynamic content wouldn't let anything to cache: I have enabled dynamic content on 3.3.8 and static content (pictures, etc) is caching correctly.

However, enabling dynamic content doesnt seem to serve its purpose: cache any URL that includes a ? (it returns a TCP_MISS/200)

This is my squid.conf. My main goal is to cache iOS updates and ibooks since I am a school IT Manager and there are 50+ identical ibook downloads per day through the iTunesU platform. The iBook URLS are like:

http://.phobos.apple.com///*/example.ibooks?downloadKey=12345678

Do you have any suggestion? Would it be wise to uninstall 3.3.8-dev and then install Squid 2.7 and manually add the refresh_patterns found in older tutorials?

Thanks in advance,

Is there is any way to run havp with squid-dev package, squid is working ok, but without antivirus, it is bit incomplete, please suggest.

marcelloc

IMHO, havp is old and obsolete but if you are not using ssl filtering, you may configure the same way you do on squid2

I'm working to get antivirus tab working for this -dev version.

exograpix

Any alternate antivirus working with ssl filtering.

Not yet.

Hello,

I have installed 3.3.8-dev and reinstalled lightsquid.

Problem is that the Proxysquid realtime stat, is either not showing client sessions at all, or, when it does, the list lines remain null and the following warning occurs several times (as many as the sessions):

gethostbyaddr(): Address is not a valid IPv4 or IPv6 address in /usr/local/www/sqstat/sqstat.class.php on line 426

Has anyone seen that before?

Thank you in advance.

ccarreraalza

I have a question.
I'm using squid 3.3.8-devel, well, when I go to facebook page shows me the warning I give exception and shows me confirm the facebook page but incompletely, as well as also the paypal page, and this because it is within the site of faccebook or https paypal there are other pages that are to be displayed, but they all come with an X.

as could validate the certificate on them to the web page or paypal facebook full display?

thanks

Google translator, sorry not mastered the English perfectly

Any tips to getting this working with dansguardian?

downloaded all the libs, installed Dans and then squid-dev, checked the boxes under squid to enable transparent mode and https MITM, installed Dans, and selected the same CA/Cert on pf.

Can see pages getting proxy'd, but no filtering is happening.

Is it possible to update the Squid3-dev package so that I can add a couple of options to the reverse proxy part? I want to disable certain unsafe protocols like sslv2. Here is an example of the line in the config file that I updated:
https_port 172.28.252.101:443 accel cert=/usr/pbi/squid-amd64/etc/squid/52038c08be9a9.crt key=/usr/pbi/squid-amd64/etc/squid/52038c08be9a9.key defaultsite=some.site.com vhost options=NO_SSLv2:NO_TLSv1 cipher=ALL:!aNULL:!eNULL:!LOW:!EXP:!ADH:!RC4+RSA:+HIGH:+MEDIUM:!SSLv2

I would like it if there would be an option in the GUI to do this. My workaround at the moment is editing the /usr/local/pkg/squid_reverse.inc file on line 85. I added the options there so they will stay in place in case I make an update to the reverse proxy.

exograpix

Any news or timeline or alternative of antivirus package compatible with squid -dev version.

Thanks
