Squid3 - New GUI with sync, normal and reverse proxy

asterix

@asterix:

Getting this error. Did a clean pfSense install. SquidGuard won't start either.. as Squid fails to start.

Apr 16 11:22:56 php: /pkg_mgr_install.php: The command '/usr/local/sbin/squid' returned exit code '1', the output was 'FATAL: Bungled squid.conf line 7: http_port 127.0.0.1:3128 intercept Squid Cache (Version 2.7.STABLE9): Terminated abnormally.'
Apr 16 11:22:56 squid[34066]: Bungled squid.conf line 7: http_port 127.0.0.1:3128 intercept

You running squid is Version 2.7.STABLE9.

What version of pfsense are you using?

Take a look on first posts of this thread to see package install sequence.

att,
Marcello Coutinho

I clean installed this version
2.0.1-RELEASE (amd64)
built on Mon Dec 12 18:16:13 EST 2011

Then went into packages and installed squid3 first. Same settings I have been using for over a year. Nothing has changed. I reinstalled pfSense again and again tried with your latest package.. same issue.

Hi guys,

I'm testing new squid3 package, and after install it, I'm having a lot errors in http connections, squid show me a lot 'TCP_MISS/503'. This happen often in forms posts, so I need re-send form ou press F5.
I tested exhaustively the squid-2.7.9_1 + squidGuard and problem no happen. So I too tested exhaustively the squid3 + SquidGuard, and I give this problem.

All squid versions have the same config. And this problem only occurs in 'Transparent Mode'

Somebdoy can please test it and report the results?!

Thanks

Hi,

so I post what I did and while I am doing this it will take more than one minute. (Remember your pm to me).

I installed squid3 package and sent myself personal messages. It took all times very long till they get sent - but that's probably a forum issue. Nothing uncommon in access.log.

After that installed squidguard - it break squid3 and squidguard so I uninstalled squid3 and reinstalled squid3. after that both were running. I created a target in squidguard to block google.de and it is working. Other pages can be visited. Nothing uncommon and not TCP_MISS/503 in access.log

I sent some personal messages myself and no problem.

Now I am writing this post and we will see what happens.

PS: I did not enable any additional options on squid - just basic settings on a VM to test.

Got the same error as ccesario:

When enabling all cache options (window supdates and so on) the squid.conf is not correctly formatted and needs some new lines before "range offset limit":

range_offset_limit -1
refresh_pattern -i microsoft.com/.*\.(cab|exe|ms[i|u|f]|asf|wm[v|a]|dat|zip) 4320 80% 43200 reload-into-ims
refresh_pattern -i windowsupdate.com/.*\.(cab|exe|ms[i|u|f]|asf|wm[v|a]|dat|zip) 4320 80% 43200 reload-into-ims
refresh_pattern -i my.windowsupdate.website.com/.*\.(cab|exe|ms[i|u|f]|asf|wm[v|a]|dat|zip) 4320 80% 43200 reload-into-imsrange_offset_limit -1
refresh_pattern liveupdate.symantecliveupdate.com/.*\.(cab|exe|dll|msi) 10080 100% 43200 reload-into-ims
refresh_pattern symantecliveupdate.com/.*\.(cab|exe|dll|msi) 10080 100% 43200 reload-into-imsrange_offset_limit -1
refresh_pattern avast.com/.*\.(vpu|cab|stamp|exe) 10080 100% 43200 reload-into-imsrange_offset_limit -1
refresh_pattern personal.avira-update.com/.*\.(cab|exe|dll|msi|gz) 10080 100% 43200 reload-into-imscache_mem 64 MB
maximum_object_size_in_memory 256 KB

Further I would make the other pattern case insensitive, too ( -i )

An what about the subdomains of microsoft.com ? Are they covered with this regex ?
Or better put .* in front like:


refresh_pattern -i .*\.microsoft.com/.*\.(cab|exe|ms[i|u|f]|asf|wm[v|a]|dat|zip)
refresh_pattern -i .*\.windowsupdate.com/.*\.(cab|exe|ms[i|u|f]|asf|wm[v|a]|dat|zip)

Further I didn't have any luck with a short test on caching youtube.com videos.
access.log shows "x-flv". Perhaps add this format to the config:

refresh_pattern -i .*\.(x-flv|flv) 10080 90% 999999 ignore-no-cache override-expire ignore-private

Thanks, I'll fix it.

On squid -> cache this:

set Maximum download size on 'traffic mgmt' squid tab to a value that fits patters your are applying.
Microsoft may need 200Mb and youtube 4GB.

should be probably renamed to:


set Maximum object size on 'cache' squid tab to a value that fits pattern your are applying.
Microsoft may need 200Mb and youtube 4GB.

Question:
Could you add an option to change the time an object should be in cache ?
At the moment it is 4320 80% 43200. Perhaps someone likes to increase that.

But probably if someone needs this he should create his custom options itself and the "click and save" GUI ist just for people who do not want to do to much work on squid and refresh_pattern :-)

The Maximum download size is on 'traffic mgmt' tab

I think the same way :)

Nachtfalke

The Maximum download size is on 'traffic mgmt' tab

This will limit all downloads through squid or am I completly wrong !?! So if I set 200MB there and will try to download an 3GB ISO it will cut my download, isn't it ?

Damn…squid has so many options it is sometime really hard to understand when to use what ;)

I second that :)

@Nachtfalke:

PS: I did not enable any additional options on squid - just basic settings on a VM to test.

My brwoser showed the attached screenshot.

After that I pressed F5 and re-sent:

Hi Nachtfalke, thank you by feedback!

This is the problem that happen! Exactly as your screenshot.

I have this screen in others sites too. I mean to you pfsense forum only to test/reproduce.

But in squid-2.7.9 this not happen.

PS: I too enable basic settings in squid.

Welll…. this can be considered a bug/error ?

So I am using squid2.7 and squidguard here on work and posting many times on the forum and there is not that "bug". Perhaps some parameters on squid3 which causes this problems. Perhaps POST HEADER size or something like that.

Do you have an URL where we can "spam" posts to test this ? Probably it is not the best to do with pfsense forum ;o)

Will do this perhaps this afternoon/night when I am at home. Perhaps we can tweak something if it's not a bug. :-)

Hmm, no luck till now.

tried with different browsers (IE8 and FF11)
tried with (re)moving some refresh_patterns
tried with different DNS servers for squid (8.8.8.8 and 127.0.0.1)
added this to custom options to get more information from access.log

strip_query_terms off

This is a difference I found on squid access.log

The 503 line uses DNS and the 302 uses an IP address…

If I click on the URL posted in the error page I get returned to the post edit page and got an error message from pfsense forum:

Marcello and others,

I've still got problems configuring Squid 3 as a reverse proxy. Somehow I can't manage it to work properly.
As you illustrated in the forst postings I did exactly the same and added NAT and Firewall rules. I'm using port 8080 and 8443.

How come…?!?!

Thanks a lot,

Still the same issue from TMG post? Did you removed the Nat?

Another bugs found on system log when I use revers proxy.

Solved! I found this problem because at dansquardian has banned "extension files". After I disable banned at extension tab, the error has gone.

Donny,
Check if does not happen if you uncheck dynamic content options on squid cache tab.
