marcelloc

version 2.0.5 is out with:

new binaries again to fix transparent proxy
new option to patch captive portal to work together with non transparent use

As I'm including new features to this package, the status is back to beta until improvements and tests are done.

dude, legend it works now. i uninstalled the package then installed.
it didn't work right away though i had to stop the package, altered the config to 32 directories to store the cache.ran squid -z, then chmod -R 777 the cache directory then rebooted.
perhaps on a fresh install that won't be needed.
thanks for your time on this. :-D

Hello all,

I have tested between Squid3 with LDAP (Windows Server 2008). I can use domain users to authentication login to web browser and successes.

pfSense configuration detail

System > General setup > DNS Servers :
172.31.21.10 (Internal DNS, DHCP Windows Sever 2008 )
208.67.222.222 (OpenDNS)
208.67.220.220 (OpenDNS)

Sevices > DNS forwarders : Enable DNS forwarders has checked.

On Windows Server 2008

At DNS forwarder tab I forward to
172.31.21.1 pfSense
208.67.222.222 OpenDNS
208.67.220.220 OpenDNS
also I have made pfsense record name on DNS server.

After domain users successes login with web browser (Firefox, IE,Opera and Chrome). At system log I got DNS-rebind attack as the detail below.

Apr 22 13:13:31 	dnsmasq[30943]: possible DNS-rebind attack detected: ForestDnsZones.xxxx.dsns
Apr 22 13:13:31 	dnsmasq[30943]: possible DNS-rebind attack detected: ForestDnsZones.xxxx.dsns
Apr 22 13:13:31 	dnsmasq[30943]: possible DNS-rebind attack detected: DomainDnsZones.xxxx.dsns
Apr 22 13:13:31 	dnsmasq[30943]: possible DNS-rebind attack detected: DomainDnsZones.xxxx.dsns
Apr 22 13:13:31 	dnsmasq[30943]: possible DNS-rebind attack detected: xxxx.dsns
Apr 22 13:13:31 	dnsmasq[30943]: possible DNS-rebind attack detected: xxxx.dsns

I tried to find another solution by google search and some pfsense forum but can not solve this problem. Also I tried to "disable DNS Rebinding Checks" or "Alternate Hostnames" or
"Browser HTTP_REFERER enforcement" at System > Advanced and domain overrides but when I do this I can not login with domain users to web browser. finally reboot pfSense and it does not help.

Any suggestion !

Hello Marcelloc,

I just would like to inform you that Squid3 authentication with LDAP Windows Server 2008 does not work very well with OpenDNS. When I only use OpenDNS 208.67.222.222 and 208.67.220.220 at System > General Setup > DNS Servers, and I try to login via web browser with domain users name, the web browser still hang up only "loading" and take too long before the web page is coming up.

The way I solved this problem is :

1. Use DNS Server from ISP : 67.xx.xxx.xx and 203.xx.xxx.xx or Use DNS Server from google : 8.8.8.8 and 8.8.4.4
2. At System > General Setup > DNS Servers. I take off IP address from internal DNS Server Windows 2008 because it will cause "DNS-rebind attack detected" If I still use internal dns ip address.

So, at System > General Setup > DNS Servers, I only use DNS Server from my ISP (67.xx.xxx.xx and 203.xx.xxx.xx) or use Google DNS Server 8.8.8.8 and 8.8.4.4. that's it.
Now I can use domain users to authenticate login via web browser and I don't get any DNS-rebind attack detected anymore. Every users from the domain that I tested, it's succeses.

SARG report at "View Report and Realtime tab", I have success to use a real user name from domain users (Windows Server 2008).

See screenshot.

Thank u very much Marcelloc

Hello Marcello,

When I reboot pfSense. At the console I saw some warning: Invalid argument supplied for foreach() in /usr/local/pkg/squid.inc on line 946.
This is squid.inc code and **this is a line 946>**foreach ($config['installedpackages']['squidremote']['config'] as $settings)

Donny,

I've pushed a fix for these array right now, wait 15 minutes, reinstall the package, and check if it stops the bootup error.

Hello Marcelloc,

After reinstall Squid3 and reboot system, the bootup error problem has solved.

Thank u

I am getting the following error after installing squid 3. I've looked at the folder and there is no mime.conf file.

I had squid 2 + squidguard. I installed squid 3, then uninstalled squid 2 and this started happening (had originally thought 3 would overwrite 2, but both were shown in the packages). I've even tried installing 3 again, but the same error happens. I would have stayed with 2, but I've always had trouble with ncix.com and some youtube videos (preview window plays video and then it runs another preview in the preview)

Apr 24 22:00:06 squid: MIME Config Table /usr/local/etc/squid/mime.conf: (2) No such file or directory
Apr 24 21:59:32 php: : SQUID is installed but not started. Not installing "filter" rules.

Apr 24 21:59:16 squid: MIME Config Table /usr/local/etc/squid/mime.conf: (2) No such file or directory

So I manually created a blank mime.conf file. That error went away and I then I in turn got a missing "icons" folder in the same location. I created that, and no squid works, but squidguard fails to work..

squid[58395]: Squid Parent: child process 58727 exited due to signal 6 with status 0

Closer, but not quite working at this stage for me…
hints anyone?

tester_02

Update:
Saved all screens in squid and squidguard for luck, and now it's up. I was scared to reinstall squidguard as I had read that squidguard would reinstall squid 2 again.

So finally squid 3 + squidguard working good. ncix.com even works! now to just watch some youtube videos and see if the problem comes up again.

installer still does need a fix for the missing file and missing folder.

Also getting error 22 invalid argument if I try to edit the message above this.

When you are able to make PBIs for installing Squid3 on 2.1-DEVELOPMENT I am happy to test it. No rush - I see that you already have plenty of work just now!

On 2.1, install package gui and then go to console to pkg_add -r binaries until I find time to build and test pbi

Hi,

I looked at throttle_exts.acl generated with "Throttle multimedia files" option checked. IMHO it lacks of extensions: wma, wav, mka, mkv, ogg, oga, ogm, ogv, rmvb.

Hi,
At "Proxy server: Traffic management" we can manage a single delay pool with the options: Per-host throttling / Overall bandwidth throttling / Maximum upload size.
I need to manage many groups of delay pools and set to different networks/Ips. This is very usefull, are you going to implement this?

Thanks in advance.

@pizetta:

No plans for this feature yet. But if you need it, you can post a bountry or make a donation for that ;)

Do you have any config sample for this?

pizetta

Something like this…

delay_pools 3 ######3 delay pools
delay_class 1 2
delay_parameters 1 -1/-1 12800/12800
delay_access 1 allow client_100k ######limited clients 100kbps

delay_class 2 2
delay_parameters 2 -1/-1 25600/25600
delay_access 2 allow clientes_200k ######limited clients 200kbps

delay_class 3 2
delay_parameters 3 -1/-1 38400/38400
delay_access 3 allow clientes_300k ######limited clients 300kbps

I wish to manage as many pools as I can, grouping users to limit the use of internet. I'll take a look at bounties.
Best regards!

Hi,

I am using package squid3 version 3.1.19 pkg 2.0.5_2.

In /usr/local/pkg/squid.inc I think this line:

http_access deny CONNECT !sslports

should be:

http_access deny connect !sslports

Also in reverse proxy web gui I need to set port 443 in order to https work. If I left blank reverse HTTPS port, it doesn't open port 443.

Also the reverse proxy HTTPS always redirect to the reverse HTTPS default site. Don't mind what mappings you use.

HTTP reverse proxy works fine.

Best regards.

When using the Reverse Proxy in theory will it redirect the traffic based upon the URL?

I've got 2 internal webservers with one public IP, should I be able to route the traffic based upon server1.mydomain.com to 192.168.1.50 and say server2.mydomain.com to 192.168.1.51 ?

It seems I've configured the reverse proxy properly and added a rule to allow http traffic to each private address but i'm not having any luck.

Anyone have any ideas or a detailed instructions?

yes,

what you got on squid access log?

nutt318

Here is what I see in the access.log file /var/squid/logs - I only see internal traffic. Shouldn't I see attempts from public IP's that are trying to access the web servers?

1338991913.168 179241 MY.DESKTOP.I.P TCP_MISS/504 1290 GET http://domain1.mydomain.com/ - DIRECT/MY.PUBLIC.I.P text/html

I'll try and add some screenshots of my setup

EDIT: added screenshots

marcelloc

The setup looks fine, I'll try to simulate it.
