Set up the Squid * * server

Abstract:

Linux is now becoming synonymous with the web. It can be usedas a file server, a print server, or a printed server in anoffice environment or a daily home.

The mail server and the application server are used and arebeing used as a * * server.

A** server can provide Internet access services to differentusers at the same time through an Internet connection. Good *

* clothing

The server also provides the caching service for the accessrequest, so that when a local access request arrives, the * *server is first checked in the cache record

Ask for the same request, and if there is, the data is sent backto the client directly from the cache, reducing the time toaccess the WEB and reducing the bandwidth

The pressure.

Squids is a software that supports Proxy, HTTP caching, Ftp,Gopher, and so on, which also supports SSL, access control, DNScache and for

All requests are recorded. Squids are also available under

Windows NT, and see Logi Sense.

The focus of this article is to configure a * * server andprovide basic guidance for users to provide controlled access.Has the squids been installed?

The Squid RPM file has been bundled with RedHat 7. 1, which isselected in the network option when the system is installedIt will automatically be installed on the system. You can checkif you've installedthe squids in your systemwiththe followingcommand:

The RPM - q squids

The latest version of the Squid can be found on the squib homepage or its mirror site. The squids can be installed on thesystem with the following command:

RPMS - ivh squid-2. stable4-10. I386. RPM

Squid conf iguration

The custom of the squids is implemented by editing itsconfiguration file, squid.conf, which is usually in

/etc/squids

Under. This configuration file has a lot of content, but thegood news is that each of its options is detailed.

The first thing you want to change is http_port, which specifiesthe port that the Squid listens on for the customer request,and the default value is 3128. To use * *

Functionality, this port value is used with the IP address ofthe machine running the squids, and can be modified to this:Http_port 192. 168.0. 1:8080

The above declaration indicates that the Squid is tied to IPaddress 192. 168.0. 1, withport 8080. The port can be set to any,but be sure

No other program USES the same port. The other service requestport Settings can also be set to a similar configuration.The above declaration indicates that the Squid is tied to IPaddress 192. 168.0. 1, with port 8080. The port can be set to anyvalue, but be sure

No other program USES the same port. The other service requestport Settings can also be set to a similar configuration.Access control

Using the access control feature, you can control for caching,accessing a particular site, or a set of sites, depending onthe time interval during the visit. The Squid access controlhas two elements: ACL elements and access lists. Access listsallow or deny access to certain users for this service.

Here are some of the important ACL element types

* SRC: source address (that is, the client IP address)

* DST: target address (that is, the server IP address)

* srcdomain: source name (that is, the client name)

* dstdomain: target name (that is, the name of the server)

* time: every day of the day and one day in a week

* url_regex: the URL rule expression matches

*urlpath_regex: the URL-path rule expression match, slightlythe protocol and host name

* proxy_auth: user authentication through an external program

* maxconn: the maximum number of connections for a single IPTo use the control function, you must first set the ACL ruleand apply it. The format of the ACL declaration is as follows:Acl acl_element_name type_of_acl_element values_to_aclNote:

Acl_element_name can be a name defined in the ACL.

Any two ACL elements cannot use the same name.

Each ACL is composed of list values. When a match is performed,multiple values are connected by logical or operation. In otherwords, either ACL

The value of the element is matched, and the ACL element ismatched.

Not all ACL elements canuse the entire type in the access list.Different ACL elements are written in a non-peer, and squidscombine them in a list.

We can use many different access entries. Here are some of thethings we're going to use:

* http_access: allows HTTP access. This is the main accesscontrol entry.

* no_cache: defines the response to the cache request.The rules of the access list are made up of key words like'allow' or 'deny' to allow or deny service to a particular orset of ACL elements.

Note:

These rules match the order in which they are sorted, and oncethe rules are detected, the matching test ends immediately.A list of access can be composed of multiple rules.

If no rule matches the access request, the default actioncorresponds to the last rule in the list.

All the elements in a access entry will be connected by logicand operation:

Http_access Action declaration 1 AND declaration 2 ANDdeclaration OR.

3 http_access Action statement

Multiple http_access declarations are used or connected, buteach access entry is used with an operation connection.Remember that the rules in the list always follow the order inthe top.

Back to the Squid conf iguration

Squid does not do any user access control by default. Customrules are required to allow a certain access. Enter thefollowing text before the http_access deny line in squi. conf:Acl mynetwork 192. 168.0. 1/255.255. 255.0

Http_access allow mynetwork

Mynetwork is the acl name, and the next line is the rule fora specific acl (that is, the mynetwork) . 192. 168.0. 1 indicatesthe network' s subnet of 255.255.255.0. Mynetwork is primarily

intended to give the network a set of machines, and the nextrule allows them

The machine accesses the HTTP service. The above modificationworks with http_port to make the squids work well. When themodification is complete, squids

You can start with the following command:

Squid service start

Note:

Squids canalso be runautomatically when the system is started,by opening the squids in ntsysv or setup (system service menu) .in

After making any changes to the configuration file, thecurrently running Squid process must be restarted. You can usethe following command:

The service squid restart or

/ etc

Configure the client

Because the client request is sent to a specific port on the

* * server, the client should also do the configurationaccordingly. Before moving on, please

Confirm that the client that is accessing the * * server hasbeen connected to the LAN and has been assigned a valid IPaddress, so make sure they all ping

The Linux server running the Squid is running.

Configuration under Internet Explorer:

Click on the tool-> Internet option on the menu

Select the connection and click the LAN Settings

Select the IP address and port to enter the above * * serverwith the * * server.

Conf iguration under Netscape Navigator:

1. Click on the menu editor (Edit) -> preferences (Preference)- > Advanced (Advanced) - > * * server (Proxi es) .

2.

Select Manual Proxy Configuration for Manual Configuration.Click View

Enter the IP address and port of the above * * server.Access control

Multiple access control and its rules provide a flexible

mechanism for client-side access control. Here are the usualexample s:

Allow the machine in the list to access the Internet.Acl allowed_clients SRC 192. 168.0. 10192. 168.0.20192. 168.0. 30

Http_access allow allowed_clients

Http_access deny! allowed_clients

This rule only allows the IP address to be 192. 168.0. 10,

192. 168.0. 20, and 192. 168.0. 30

Access to the Internet and other IPaddresses are deniedaccess.Limit access times.

Acl allowed_clients SRC 192. 168.0. 1/255.255.255.0

Acl regular_days time MTWHF 10:00-16:00

Http_access allow allowed_clients regular_days

Http_access deny! allowed_clients

This rule allows all clients in subnet 192. 168.0. 1 to be from

10:00 a.m. to 4:00 p.m. Monday through Friday

Access to the Internet.
