Squid3 - New GUI with sync, normal and reverse proxy

jimp

NAT is indeed the easy solution there.

However, as to the second point: I am using 2.1-BETA, and I do not see any such option. ("squid3" package, version "beta 3.1.20 pkg 2.0.5_3")

I said it will, I did not included the code to squid package yet ;)

Hi, my squid cannot start :'(, here is the message in cache.log:

I have tried both squid 2 & 3, both got the same message ::)
Also it seems there is no "ssl_crtd" exist in my system…so I cannot try to run the command :o
Do you have any suggestion..? :'(

Thanks

I have this dir on my squid3 install.

What are you trying to configure?

ls -la /var/squid/lib/

Hey guys,

I have a strange problem regarding reverse proxy and authentification with Certificates… The package itself is working as expected and without certs needed to authenticate I can open all services (owa, msas, rpc).

Now here it comes: (all IP's, ports and url's are renamed for security reasons ;) )

if i use this line in my squid.conf:

https_port xxx.xxx.xxx.xxx:Port cert=/website.crt key=/website.key defaultsite=this.website.me vhost

everything works as expected. I get my login page… but if I use this one:

https_port xxx.xxx.xxx.xxx:Port cert=/website.crt key=/website.key defaultsite=this.website.me clientca=/CA.crt cafile=/CA.crt capath=/ sslcontext=id vhost

I get asked for my client cert and then "page cannot be found" with this in squid logs:

clientNegotiateSSL: Error negotiating SSL connection on FD 17: error:0D0C50A1:asn1 encoding routines:ASN1_item_verify:unknown message digest algorithm (1/-1)

My CA is created with SHA512… So the clients are too ;)
When I do

openssl list-message-digest-commands

on my pfsense shell, I get

md2
md4
md5
mdc2
rmd160
sha
sha1

But with openssl speed, sha512 is listed!

What I found so far is, that somewhere in the squid source this line should be added

OpenSSL_add_all_algorithms()

somwhere like

src/ssl_support.*
function: ssl_initialize(void)

Due to the lack of time, I wasn't able to get deeper inside… Does someone has an idea?!

@marcelloc:
If this needs to be posted somewhere else, please let mo know. If I understand this package right, you are compiling squid on your own?! So this could be solved easily...

Kind regards

EDIT:
found it in src/ssl_support.cc, line 593

SSL_load_error_strings();
SSLeay_add_ssl_algorithms();

what i found by google, there should also be called: OpenSSL_add_all_algorithms()

@marcelloc:
possible?

No more :(

Packages now must be only compiled and provided by official repo, you can compile it on 8.1 freebsd, create the package and then install on your system.

Core team are really busy these days. I'm waiting some packages to be recompiled too. After this, I can continue package development and testing.

these are current squid3 compile options available on ports

SQUID_KERB_AUTH Install Kerberos authentication helper

SQUID_LDAP_AUTH Install LDAP authentication helpers

SQUID_NIS_AUTH Install NIS/YP authentication helpers

SQUID_SASL_AUTH Install SASL authentication helpers

SQUID_VIA_DB Enable forward/via database

SQUID_CACHE_DIGESTS Enable cache digests

SQUID_WCCP Enable Web Cache Coordination Prot. v1

SQUID_WCCPV2 Enable Web Cache Coordination Prot. v2

SQUID_STRICT_HTTP Be strictly HTTP compliant

SQUID_IDENT Enable ident (RFC 931) lookups

SQUID_REFERER_LOG Enable Referer-header logging

SQUID_USERAGENT_LOG Enable User-Agent-header logging

SQUID_ARP_ACL Enable ACLs based on ethernet address

SQUID_IPFW Enable transparent proxying with IPFW

SQUID_PF Enable transparent proxying with PF

SQUID_IPFILTER Enable transp. proxying with IPFilter

SQUID_FOLLOW_XFF Follow X-Forwarded-For headers

SQUID_ECAP En. loadable content adaptation modules

SQUID_ICAP Enable ICAP client functionality

SQUID_ESI Enable ESI support (experimental)

SQUID_AUFS Enable the aufs storage scheme

SQUID_COSS Enable COSS (currently not available)

So if I would have a FreeBSD 8.1, download squid sources and build it with all the options marked in your post, we could run the binaries on pfsense?

EDIT:
could I use squid 3.2.1 source? or won't this one run on pfsense?

EDIT #2:
downloading freebsd 8.1 i386. will try to get things work.

@marcelloc:
please let me know, which version of squid I should compile. 3.1.19, 3.1.20 or 3.2.1?

marcelloc

The best way is to use freebsd ports to compile.

Portsnap fetch
Portsnap extract

CD /usr/ports/www/squid31
make package

Hobby-Student

why don't we use version 3.2.1?

marcelloc

It's not on ports yet. To create the package for 3.2.1 we need first a port for it.
We can try to create it based on 3.1.20 dir

Hobby-Student

did it.

here we go:
compiled squid 3.1.20 with ports on FreeBSD 8.1. I modified the source and now squid is able to authenticate users with certs (all digests) in reverse mode… i try to find some place to upload the binaries.

EDIT:
forgot to ask… are you interested in including "my" squid version? I just added the mentioned one line in the source....

marcelloc

Post what you did. Maybe I can send it as a feature request to squid port maintained @ freebsd

Hobby-Student

this is what i did:

source file: ssl_support.cc, around line 593 (in squid 3.2.1 the file is located in "ssl" subdir named "support.cc")

function: ssl_initialize(void)

original:

SSL_load_error_strings();
SSLeay_add_ssl_algorithms();

to:

SSL_load_error_strings();
OpenSSL_add_all_algorithms();
SSLeay_add_ssl_algorithms();

would you like to include my binaries in your package?

marcelloc

@namek:

I am using this mainly for content filtering/caching/logging…

squid3 has some new features on it's gui too, check it on a test machine first.

marcelloc

@namek:

Oh yes, one the features I found was 'patch captive portal' - which I believe that if the users are on a proxy they will not be able to bypass captive portal?

yes. I did it based on some topics on this forum with problems on using captive and squid.

@namek:

And ofcourse there are more features..are many users using this in production? as you have marked it as "Beta"
another striking feature are the realtime logs integrated in the GUI itself. So i believe that somewhat eliminates the need of using the 'realtime' feature of both sarg and lightsquid…

The realtime tab on squid3 package is to help debug access while using squid and squidguard.

Hi all, i have install squid3 package and just use standard config, squid reverse not config yet. After install i have problem to access banking website and got error msg from squid Unable to determine IP address from host name "www.cimbclicks.com.my". How can i solve this problem? Below my squid config.

Dns v4 first turned on was the latest workaround for this https issue.

Did you tried to stop and start squid after this change?

TyperX

It's working now, i have restart the pfsense. Thanks for the help ;D

Hi,

short question:
Is squid3 completly ready fpr pfsense 2.1 ?
It installs and it starts on pfsense 2.1 but there are some errors on systemlog because of the wrong path "/usr/local/etc/".

Further in the squid.inc there is no code to differentiate between pfsense 2.0.x and 2.1.
Did I miss something or does the squid3 package need some more work to be ready for 2.1?

Thank you :-)

I've committed a folder check right now, check and feedback :)
