Squid 3.3.4 package for pfsense with ssl filtering

wheelz

ok, my fault. I had copy pasted the wrong PACKAGESITE path. I have that fixed now and squid starts fine, but still the same as before. HTTP goes fine but HTTPS just sits trying to connect. I just have HTTPS/SSL interception enabled on the loopback adapter, port 3129 (NAT rule to forward 3129 and firewall rule allowing it in). My TestCA certificate is selected and I left the rest as the defaults. My client has the TestCA certificate installed in the trusted CAs and I configured the SSL proxy to my pfsense on port 3129.

Here is what squid says:

Port 3129 connect via telnet but HTTPS connections time out without anything mentioned in the sys logs or access.log. Am I doing something wrong?

No need to create a nat rule.

Remove your nat, enable SSL on interface other then loopback and let squid do the config for you.

I still need to have a firewall rule allowing port 3129 in on the interface IP, correct? Also I'm explicitly setting the SSL proxy IP/port. That will work right? Currently my traffic is going through another firewall so it would be hard for me to test it via transparent.

You need to configure ssl filtering port only on transparent mode.

On normal proxy configuration, traffic(http and https) goes fine on default squid port.

Ok, I got the explicit squid proxy to pass https with no problem now. If I want to test the transparent https proxy then I just enable it with the CA cert I have? The default port is 3129 but clients won't be sending on that port. Do I need to change that to 443 then? Or should I NAT redirect it instead?

Also have some DG questions but I'll put then in the other thread.

Just enable it on LAN for example. Squid package will create rules to transparent proxy connections from 443 to localhost 3129.
do not select loopback on squid config while using transparent mode.

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.

on 2.0.3, use pkg_add and pkg_delete to get squid 3.3.5

i386
pkg_add -r http://e-sac.siteseguro.ws/packages/8/All/squid-3.3.5.tbz

amd64
pkg_add -r http://e-sac.siteseguro.ws/packages/amd64/8/All/squid-3.3.5.tbz

Hmm… that's what I did. It complained about perl and openssl (I think) so I deleted them and let the pkg_add -r install the versions it wanted. After that it was successfull, however squid -v won't run with the error above.

When I do that, it complains that perl is the wrong version.

check all dependent libs from the beginning of this topic. The manual update works fine if applied on with same architecture as operating system.

I got this when I start Squid (that stops immediatly)

What config are you using? reverse proxy? normal proxy? did you configured a valid CA for squid?

While using transparent proxy, do not select loopback interface.

stanthewizard

I have removed 3.3.4

I followed your commands line for 3.3.5. But no squid … after reinstallation, I'll see if I still have the error message.

Thanks for your help

fill ssl fields (port, etc) and save config.

check if all libs are there with squid -v

stanthewizard

I don't understand
squid -v give me a lot of file.

but no squid in menu or packages :-X

The upgrade process from 3.3.4 to 3.3.5 is only on console. You do not need to remove squid3-dev package on gui.

stanthewizard

Damned

How do I reinstall the console ?

Thanks

stanthewizard

On one of the Pfsense 2.1RC0 … I nailed the SSL Certificat culprit.
The service is UP with this in the log:

php: /status_services.php: The command '/usr/local/etc/rc.d/squid.sh stop' returned exit code '1', the output was '2013/06/07 08:02:02| ERROR: Directive 'ignore_expect_100' is obsolete. squid: No running copy'

marcelloc

@stanthewizard:

How do I reinstall ~~the~~ on console ?

Reinstall package squid3-dev via gui.

Go to console/ssh, remove with pkg_delete squid-3.3.4 and install using pkg_add squid-3.3.5.

@stanthewizard:

ERROR: Directive 'ignore_expect_100' is obsolete. squid: No running copy'

I've pushed a fix with no version bump. a package reinstall should fix it.

If you what to just manual update it, run these two fetch cmd on console

fetch -o /usr/local/pkg/squid_reverse.inc https://raw.github.com/pfsense/pfsense-packages/8ba97bb7780495943c2d50547514d5b388d06329/config/squid3/33/squid_reverse.inc
fetch -o /usr/local/pkg/squid_reverse_general.xml https://raw.github.com/pfsense/pfsense-packages/8ba97bb7780495943c2d50547514d5b388d06329/config/squid3/33/squid_reverse_general.xml

Aouch

with pkg_add
