Squid Proxy Server on Ubuntu Linux

Proxy can be understood as a third party who mediates between two networks so that the first party and second party does not relate directly, but by the intermediary of Proxy. In this section, we will try to install and configure squid proxy with the simplest configuration.




1. Install Squid

Code:

sudo apt-get install squid 

2. Copy default configuration before editing

Code:

sudo cp /etc/squid/squid.conf /etc/squid/squid.conf.backup 

3. Edit file squid.conf with assumption :
    a) Connected to the Internet
    b) Local network that is used is called LecturerLAN with network
        192.168.7.0/24
    c) Hostname (localhost ubuntu server) is ubuntuserver.com with ip
        192.168.7.1/24
    d) All configurations beyond the addition below, still using the default squid

Code:

sudo nano /etc/squid/squid.conf 

Code:

acl LecturerLAN src 192.168.7.0/24 
http_access allow LecturerLAN 
htpp_access deny all 
http_port 8080 
cache_mem 64 MB 
memory_replacement_policy lru 
cache_replacement_policy lru 
cache_swap low 90 
cache_swap high 95 
visible_hostname ubuntuserver.com

    Save it by pressing CTRL + X press Y and Enter

4. Restart Squid

Code:

sudo /etc/init.d/squid restart 

5. Now edit configuration of the host machine
    In Firefox (Linux machine)

Code:

Edit -> Preferences -> Advanced ->Network -> Settings 
Manual proxy configuration: 
HTTP Proxy : 192.168.7.1 
Port       : 8080
