Squid is a high-performance caching proxy server that stores frequently accessed web content to improve network efficiency. It reduces bandwidth usage on busy networks by caching content locally. Squid communicates with peer caches using the Inter-Cache Protocol and can operate as a traditional proxy or front-end accelerator. Configuring Squid involves setting up TCP/IP on the server, editing squid.conf to change ports and define access rules, restarting Squid, and configuring clients to use the Squid server address.

SQUID SERVER: Squid is a high-performance HTTP and FTP caching proxy server. It is also known as a Web proxy cache. It can make your network connections more efficient. As it stores data from frequently used Web pages and files, it can often give your users the data they need without their systems having to look to the Internet. Studies on very busy networks suggest that a Squid server can reduce the size, or bandwidth, of your Internet connection. That can lead to considerable savings for larger offices. Squid uses the Inter-Cache Protocol (ICP) for transfers between participating peer and parent/child cache servers. It can be used either as a traditional caching proxy or as a front-end accelerator for a traditional Web server. STEPS TO CONFIGURE SQUID PROXY SERVER : 1. Configure a TCP/IP for Squid Server : [root@localhost /]# netconfig or system-config-network or setup IP address: ________________ Netmask: ___________ _____ Default gateway (IP): ___________ _____ Primary nameserver: ___________ _____
2. Configure the /etc/squid.conf file : 揃 Change the default port no to 8080 揃 Create a acl rule under the 127.0.0.01 揃 Create a http_access allow and deny rule under the http_access [root@localhost /]# vi /etc/squid/squid.conf 揃 Go to the port line : /3128 and change the port #detault: http_port 8080 揃 Go to the line and create a acl rule: /127.0.0.01 #Recommended minimum configuration: # Near the src acl src section #Recommended minimum configuration: acl all src 0.0.0.0/0.0.0.0 acl manager proto cache_object acl localhost src 172.16.0.0/255.255.0.0 acl to_localhost dst 127.0.0.0/8 acl yahoo dstdomain .yahoo.com acl gmail dstdomain .gmail.com acl cric dstdomain .cricinfo.com acl CONNECT method CONNECT 揃 Go to the line and allow the rules: /http_access #Recommended minimum configuration: # Only allow cachemgr access from localhost http_access deny yahoo http_access deny gmail http_access allow cric http_access allow local Restart the Squid services:
[root@localhost /]# service squid restart [root@localhost /]# /etc/init.d/squid restrart On the service of Squid server : [root@localhost /]# chkconfig squid on ON CLIENT SIDE : Configure a TCP/IP for your Lan computers : [root@localhost /]# netconfig or system-config-network or setup IP address: ________________ Netmask: ________________ Default gateway (IP): ________________ Primary nameserver: ________________ Go to the internet explorer Edit -> preferences -> internet connections-.
