User Authentication

A common requirement is to add user authentication so that only known users within the network can get web access via Squid. The simplest way to do this is to make use of whatever authentication methods are available on the machine where Squid is running, using PAM (Pluggable Authentication Modules). To do this, you need something like the following in /etc/squid/squid.conf:
.NET bar code printer on .net
using visual .net todraw bar code with asp.net web,windows application
auth_param basic program /usr/sbin/pam_auth
Control uss code 128 size on visual c#.net
to deploy code128 and code 128b data, size, image with visual c#.net barcode sdk
This says that you should use PAM for authentication: Whatever authentication method is valid will now be employed, whether it be /etc/passwd, NIS, LDAP, or some other method. (See 24 for a discussion of PAM authorization.) To force the authentication to take place, you need a line (after the one shown previously) like this:
Control code128 image for .net
use web code-128 development todisplay code128b for .net
acl lanauth proxy_auth REQUIRED
Control code-128c image in vb.net
use .net vs 2010 code-128c development toget code 128 in visual basic.net
and a corresponding line later in the file like this:
.net Vs 2010 Crystal gs1 - 12 integrating on .net
using .net crystal tocreate upc a on asp.net web,windows application
http_access allow lanauth
Universal Product Code Version A generation in .net

Now when you try to access a web site for the first time from a client machine, you will see something like Figure 25-2.

If you can now authenticate with a username and password known to the server, everything will work. Combining user authentication with the acl that defines the local network is best done something like this:
Control ean / ucc - 13 image in c#
using visual .net tocreate gs1 - 13 in asp.net web,windows application
acl lan src 192.168.1.0/24 auth_param basic program /usr/sbin/pam_auth acl lanauth proxy_auth REQUIRED http_access deny !lan http_access allow lanauth http_access allow lan ... http_access deny all

In other words, you deny anyone not on the desired network addresses before you force the authentication; then you allow the access from the network segment. As noted previously, if necessary, you can also set up separate acls for individual IP addresses. This type of authentication uses the standard HTTP authentication method. This means that username/password pairs are being transmitted across the network in base64 encoded form (that is, not simple plain text, but not encrypted either). If a method of authentication is being used that is also available for other purposes on the server (as with the pam_auth example), there is an inherent security risk, which could potentially compromise users accounts on the server. This risk is avoided with the digest_pw_auth method. For this you need lines similar to the following in /etc/squid/squid.conf:
Sql Database ean / ucc - 13 maker in .net
use sql server uss-128 generation toconnect ucc - 12 for .net
auth_param digest children 5 auth_param digest program /usr/sbin/digest_pw_auth /etc/squid/digestpw auth_param digest realm Squid proxy-caching web server
Web Form Crystal upc-a writer on vb
using barcode creation for asp.net aspx crystal control to generate, create upca image in asp.net aspx crystal applications.
Here you specify a password file /etc/squid/digestpw. You could have specified any suitable location for this file. With the current version of Squid, this file is a plain text file with entries of the form
Control pdf-417 2d barcode image on .net c#
use .net barcode pdf417 integrated toembed pdf 417 on visual c#.net
username:password
Bar Code barcode library on font
generate, create barcode none for font projects
The passwords are stored in plain text (we understand this will change in future versions), so the file s ownership and permissions should be squid:root and 600. In other words, it should be readable and writeable by the Squid user and not readable by anyone else. Now when a client starts a session, Squid authenticates using the information in this file. However, this does not require a password to be sent across the network. Instead, the server and client each calculate an MD5 sum or one-way hash based on the password and the URL (and some additional per-session information offered by the server). The client sends the result of its calculation to the server, which compares them. Most browsers will cooperate correctly with this form of authentication. However, we have seen some problems with Konqueror, but Internet Explorer, Mozilla, Galeon, and Firefox all appear to work perfectly with it. The other authentication methods that are shipped with SUSE s Squid package are all installed into /usr/sbin/ and are msnt_auth, ntlm_auth, smb_auth, yp_auth, getpwname_auth, ncsa_auth, and squid_ldap_auth.

Thus, it is possible to use Windows, Samba, LDAP, or YP as the authentication method. However, for most of these, the remarks given previously about unencrypted passwords crossing from the client to the server hold true.
