Squid3 - New GUI with sync, normal and reverse proxy

[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

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

@nutt318:

Make URI textbox blank in order to get:

acl test1 url_regex -i http://test1.mydomain.com.*$

Now you get:

acl test1 url_regex -i test1.mydomain.com/http://test1.mydomain.com.*$

You can look at /usr/local/etc/squid/squid.conf in a ssh shell.

Best regards.

That made it work from internal on the LAN, but I still cant get to it from the outside.

Any other ideas?

Thanks!

Unable to get reverse squid 3 to work.  Here is my configuration, if somebody can help.  The example i'm trying to get to work is 2 web servers; one on port 80 and another on port 8081.  The request comes to port 80 should be pickedup by squid and depending on the URL squid should send the request either to port 80 of the web server or to port 8081.  The test Im using is www goes to port 80 and helpdesk goes to port 8081.  When I try it, everythings goes to port 80. Port 8081 is never sent aqnything and the helpdesk goes to port 80.

The squid.conf file reverse proxy section looks like this: (XXX is equal to mydomainname)

Reverse Proxy settings

http_port 156.34.XXX.XXX:80 accel defaultsite=XXXX.ca vhost

Sounds like the same issue I'm having, however it looks like one of your mappings isnt ON. Maybe that will fix it, if so I need to look over my config again.

[nutt318]

I looked at my squid.config file at its basically the same as cjbujold's.

Is there anything else to try, or does anyone have any idea why this isnt working?

Thanks for the help.

Hi,

There is no possible to restart/start squid service from dashboard and services GUI pages.

Hi,

IMHO squid as a package for firewall should be hardened a little bit more.
From my perspective ACL safe_ports should include only 21, 80, 443 and 1025-65535 ports, ACL SSL should include only 443 port. All other ports should be added manually.
There could be information about other ports in description of the options.

The brilliant function could be possibility to manage the ACLs like in Webmin or like firewall rules in pfSense.

Best regards

Apply this patch on your 2.0.1 install to fix restart service option

the current list (21 70 80 210 280 443 488 563 591 631 777 901 1025-65535) is not that big. I think(and in some cases I remove) that 1025-65535 is the most "unsecure" port range on this array. You can chage it editing squid.inc file.

It's on the todo list, but I need some free time to finish.

Did you ever have a chance to simulate the reverse proxy traffic?

Squid services not started :(

-php: /pkg_edit.php: The command '/usr/local/sbin/squid -k shutdown' returned exit code '1', the output was 'FATAL: Bungled squid.conf line 4: http_port 127.0.0.1:3128 intercept Squid Cache (Version 2.7.STABLE9): Terminated abnormally.'

@Blasterreal:

Squid Cache (Version 2.7.STABLE9)

Did you installed squidguard after squid? force a squid3 reinstall, check config, apply settings and test again.

[blasterreal]

Thanks its working ;)

thanks. Guess I should had read the whole thing… I missed the bottom part

EDIT:  Squid 3 has been built it looks, http://files.pfsense.com/packages/8/All/squid-3.1.19-i386.pbi

EDIT2: Since the package showed up, I installed it... Looks like it needs some options added to it when the pbi is being built:

It wont start, I manually was able to start squid by taking the unrecognized commands out.. hand edit the squid.inc file so they aren't added

EDIT3: Still testing but looks like option -f will be needed to keep the config files in the same location:

-f file  Use given config-file instead of
                /usr/pbi/squid-i386/etc/squid/squid.conf

[jimp]

What build_options were used when making the custom package? I can add whatever is needed to get it building. I tried adding ECAP and that just blew up the build.

If it isn't known, just get /var/db/ports/squid/options from the box that built the current .tbz and post it and I can translate it into the syntax we need.

And yes all packages with config files should be using whatever parameter is there like -f to manually specify where you want the config (should really be /var/etc/something, not /usr/local/etc/something)

thanks Jim, I'll let Marcelloc charm in on the dev stuff ;-)
