Re: different authentication for different ports

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Amos,

That was exactly what I was looking for.  I tried it and it seems to work just like I wanted.  My other alternative would have been to run 2 copies of squid, but this is much cleaner from my perspective.  Thank you very much!

Amos,

If the website that is being asked for is not in the whitelist, won't it fall through and ask for authentication?  That is how it seems to work to me.  That's why I am thinking I need 2 different ports or something to do what I want.

You do need two different ports regardless of the http_access rules. One for the forward/explicit proxy traffic and one for the intercept/tproxy traffic. The TCP IP:port details for each of those "modes" is given in completely different ways and the HTTP message syntax is also different so the *cannot* be delivered to the same ports.


A whitelist generally is formed from two lines, one allowing and one denying everything else.

If 'everything else' is defined as just the stuff arriving in one specific port you get this:

 http_port 3128
 http_port 3129 intercept

 acl portX myportname 3129

 http_access allow portX whitelist
 http_access deny portX

 http_access deny !login
 ...

        Hi all.  I've got a fairly basic squid config set up on linux.         I have basic authentication set up on it to the default 3128
        port, and it works just fine.  I would like to keep this
        configuration.  However, I would like to set up another port
        that only allows a certain whitelist of websites that doesn't
        require or ask for authentication.  I want to set this up for
        certain apps that don't have proxy settings built into them.  I
        want windows to be able to connect to some sites, but not
        everything and if it can't reach the site, I don't want it to
        ask for credentials.  With my current configuration, it asks for
        credentials for any app that is trying to connect to a
        non-whitelisted website.  Is this configuration possible and do
        you have an example?  Sorry if this has been answered before, I
        am very green to squid yet.


    Simply place the http_access rules for handling that traffic above
    the first line which requires authentication.

       http_access ... lines that dont require auth.

       acl login proxy_auth REQUIRED
       http_access deny !login

       http_access ... rules for authenticated users.
