So if I understand you correctly, squid follows the behaviour dictated
in the Netscape Cookie Specification (undated), which says set-cookie
headers should never be cached. However, that was superseded by rfc2109
(1997), which says they should be cached unless told not to.

So by that reasoning, I would say Squid does not follow rfc. Not that I
care that much, but perhaps it would warrant an update in the
documentation or the faq page?

2010-05-20 Thread jyothi
Hello All,

I want to use the redirect_url_program when there is a change ip address of my 
system.
Is it possible to detect the change in ip using squid proxy? Let me put in 
other words,
Can squid proxy communicate to any of the system applications, lets say a shell 
script?

Thanks




[squid-users] squid_kerb_auth Squid_kerb_ldap (Squid 2.7)

2010-05-20 Thread GIGO .

Hi all,
 
Does squid_kerb_auth  squid_kerb_ldap work fine in squid 2.7 like squid 3.x.
 
 
Are these the correct options?
 
./configure *...*--enable-basic-auth-helpers=LDAP 
--enable-auth=basic,negotiate,ntlm 
--enable-external-acl-helpers=wbinfo_group,ldap_group 
--enable-negotiate-auth-helpers=squid_kerb_auth

 
One more question is that i not mentioned squid_kerb_ldap here is it being 
covered through --enable-external-acl-helpers=ldap_group ???

If you are using NetworkManager then an easy spot for integrating things
like this is by placing a action in /etc/NetworkManager/dispatcher.d/

This is used by the Squid rpm on Fedora to automatically react on
network interface changes which changes /etc/resolv.conf and some other

[squid-users] Advices for a squid cluster with kerberos auth

2010-05-20 Thread Emmanuel Lesouef
Hello,

I'm currently satisfied with my round-robin DNS enabled cluster of
two Squid with ntlm authentication.

But, with th appearance of Windows 7 and Windows 2008, I see by
searching for documentation on the web that I need to use Kerberos
Authentication if I would like Internet Explorer 8 from 2008 or 7 to
work.

Do you have any advices for achieving this setup ? What clustering
mechanism do you use. Does the kerberos part of the install need to be
customized to support being put in cluster mode (which needs to be
defined) ?

Thanks for your helps and docs.

PS : Testing it will be easy so I thinks I'll enable Debian Backports
repository in order to have 2.7STABLE9.

Without havign used either, I expect if your clustering setup works with 
NTLM it will work equally well or better for Kerberos.


The two protocols are very much similar, with Kerberos doing away with 
one of the handshake HTTP reject messages.

Yes. Squid has it's own built-in ramdisk equivalent for memory caching 
the most popular or recent objects.


It's size is defined by the cache_mem setting which may be used with or 
without the disk caching.



To run diskless:

 * 3.0 and numerically lower there is a null disk type to set on 
cache_dir line and override the default 100MB on-disk cache.


 * 3.1+ have no such default on-disk so removing all cache_dir lines is 
the same end result.

There is a squid.conf option for Windows machines (only).

[squid-users] Installed Squid and now what?

2010-05-20 Thread Mustafa Aydemir

Hi,

I am new to squid and i am here for just one reason. I have been looking 
for caching mp3s stored on my server to save bandwith and also block 
downloading them. I found out that squid does both of these best. I have 
installed 3.1.0.15 version but now i really dont know what to do. There 
are many examples on web but some gave errors so i decided to listen to 
squid community.


Can you please give me some documentation or examples about

1. How will i let squid to work without changing browsers proxy 
settings? I mean it will be availabla for all visitors.

2. How will i cache mp3s to save bandwith?
3. This is not important but it would be great if users just can listen 
them but cant download?


Please tell me that these can be done.

Thank you all.

Re: [squid-users] Installed Squid and now what?

2010-05-20 Thread Nyamul Hassan
Did you read the following:

http://wiki.squid-cache.org/SquidFaq/ReverseProxy
http://wiki.squid-cache.org/ConfigExamples#Reverse_Proxy_.28Acceleration.29

These will give a very good idea on what this involves, and will answer your #1.

For #2, if your Squid is hosted nearer to your users, then it might
save you bandwidth.  But, if Squid is hosted just beside your HTTP
server (as is usually the case), then it will not save bandwidth for
you.  What it will do is, it will help save resources on your HTTP
server (mostly if HTTP server is on a separate machine), so that you
can server more users.  Squid is more efficient at file delivery than
an HTTP server.

For #3, this is not the premise of Squid (AFAIK).

 Hi,

 I am new to squid and i am here for just one reason. I have been looking for 
 caching mp3s stored on my server to save bandwith and also block downloading 
 them. I found out that squid does both of these best. I have installed 
 3.1.0.15 version but now i really dont know what to do. There are many 
 examples on web but some gave errors so i decided to listen to squid 
 community.

 Can you please give me some documentation or examples about

 1. How will i let squid to work without changing browsers proxy settings? I 
 mean it will be availabla for all visitors.
 2. How will i cache mp3s to save bandwith?
 3. This is not important but it would be great if users just can listen them 
 but cant download?

 Please tell me that these can be done.

 Thank you all.

[squid-users] IPv6 slow on internal sites

2010-05-20 Thread FRLinux
Hello,

We have installed Squid 3.1.3 (compiled from sources using a spec file
I found for version 3.0.3 at the time) on a CentOS 5.5 server (i386).
We are seeing slow loading of images on all IPv6 internal sites (but
not to external IPv6 sites). Loading test is instant, just images is
causing problems.

I was wondering if that is something that anyone here might have
encountered? I was thinking of some possible pmtu issue but after some
experiments, it does not seem to be the case.

I have also tried to specify direct access for the sites, but that
didn't fix it:

acl INSIDE dst 2001::xx::/48
always_direct allow INSIDE

Any suggestion welcome.

Cheers,
Steph

I think the fisrt thing i might do is understanding normal and reverse

---BeginMessage---
1. You need to set up Squid in transparent mode
2. The bandwith saving, I think is only for normal proxy no for reverse
proxy
3. If you can read it, you can copy it.

RE: [squid-users] refresh patterns for Caching Media

 Subject: [squid-users] refresh patterns for Caching Media


 Hello eveyone,
 We are using Squid 2.7 for caching educational media files.   We are only 
 using the cache for users who need to access these files.   For other 
 internet traffic the cache will be bypassed.
 The media files will not be changed for at least a year at which point I will 
 run a script to pre-load the cache with the new media files.

 1. How can I set the refresh pattern to never refresh these media files?   
 The files are swf (flash) flv, and mp3, etc.
 This is what I currently have for media:

 refresh_pattern -i \.(iso|avi|wav|mp3|mp4|mpeg|swf|flv|x-flv)$ 43200 90% 
 432000 override-expire override-lastmod reload-into-ims ignore-reload 
 ignore-no-cache ignore-no-store ignore-private

 2. If  I have already pre-loaded media files into the cache, will changes to 
 the refresh patterns work retroactively on these files, or will I have to 
 load them into the cache again?

 Thanks.

 Kafriki



does anyone have any suggestions or recommendations that they can share with me

[squid-users] Slowness in downloading files, but not web browsing

2010-05-20 Thread Kelly, Jack
Hi everyone,
We're running Squid 3.1.1 on a virtual Ubuntu x64 server sitting on a
fiber LUN. It's been up for a couple of months without issue any issues
until recently.

Over the past week or so I've had users calling in to report that
downloading files from the internet has been very slow. They'll start
out with a fast download speed, but it will quickly go down to about
5kb/sec.

If I circumvent the proxy server and connect to these sites directly,
the download goes right through no problem.

I've tried restarting the Squid service with no luck. Any suggestions?

Thanks
Jack

Found what the problem was, thought I should report even though it has
nothing to do with Squid. Problem is Broadcom chipset related, TSO
makes it behave at 16K/s when sending IPv6 packets (TX, does not
affect RX). Bug: https://bugzilla.redhat.com/show_bug.cgi?id=531270

Just to be clear, the problem is not on the squid server but on the
IPv6 server (which incidentally, is a kvm server).

So that fixes it: ethtool -K eth0 tso off

Do you have any advices for achieving this setup ? What clustering

customized to support being put in cluster mode (which needs to be
defined) ?

Thanks for your helps and docs.

PS : Testing it will be easy so I thinks I'll enable Debian Backports

Without havign used either, I expect if your clustering setup works with 
NTLM it will work equally well or better for Kerberos.


The two protocols are very much similar, with Kerberos doing away with one 
of the handshake HTTP reject messages.

[squid-users] 2.7 upstream parent (cache_peer) connection reset. Child how to handle?

2010-05-20 Thread James Tan
Hi,
I have a PoC of 2 Squids. One act as Parent and the other as Child.
I tested a website that Parent will cause browser (directly configured
to use Parent as proxy) to received connection reset. Other web pages
are passed and viewed normally.
When I tried to chain Child to Parent, and the browser (configured to
use Child), the browser hung on the 'reset' page until The requested
URL could not be retrieved. Other normal pages are retrieved and
viewed fine.

Browser -- Child -- Parent -- 'reset' Site
(http://www.eicar.org/download/eicar_com.zip)  = hung-then-failed.
Browser -- Parent -- 'reset' Site
(http://www.eicar.org/download/eicar_com.zip) = immediate received
conn reset view.

How can I configure the Child to see what the Parent see?
By the way, I am using a malware/AV scan engine on the Parent OS, thus
the conn reset when chanced bad sites/pages e.g. EICAR test.
thanks,
James Tan
