Starting Squid

Use the chkconfig configure Squid to start at boot::

[root@bigboy tmp]# chkconfig squid on

Use the service command to start, stop, and restart Squid after booting:

[root@bigboy tmp]# service squid start

[root@bigboy tmp]# service squid stop

[root@bigboy tmp]# service squid restart

You can test whether the Squid process is running with the pgrep command:

[root@bigboy tmp]# pgrep squid

You should get a response of plain old process ID numbers.

• A firewall while simultaneously being your home website’s mail, web and DNS server.
• A router that will use NAT and port forwarding to both protect your home network and have another web server on your home network while sharing the public IP address of your firewall.

Creating an iptables firewall script requires many steps, but with the aid of the sample tutorials, you should be able to complete a configuration relatively quickly.
