Setup Transparent Squid Proxy Server in Ubuntu

Squid is a fully-featured HTTP/1.0 proxy which is almost (but not quite – we’re getting there!) HTTP/1.1 compliant. Squid offers a rich access control, authorization and logging environment to develop web proxy and content serving applications.

This is a short guide on how to set up a transparent squid proxy server. Squid is a caching proxy for the Web supporting HTTP, HTTPS, FTP, and more. It reduces bandwidth and improves response times by caching and reusing frequently-requested web pages. Squid has extensive access controls and makes a great server accelerator.

Shorewall Configuration in Debian

What is Shorewall?

The Shoreline Firewall, more commonly known as “Shorewall”, is a high-level tool for configuring Netfilter. You describe your firewall/gateway requirements using entries in a set of configuration files. Shorewall reads those configuration files and with the help of the iptables utility, Shorewall configures Netfilter to match your requirements. Shorewall can be used on a dedicated firewall system, a multi-function gateway/router/server or on a standalone GNU/Linux system. Shorewall does not use Netfilter’s ipchains compatibility mode and can thus take advantage of Netfilter’s connection state tracking capabilities.

DHCP Server using Slackware

The Dynamic Host Configuration Protocol (DHCP) allows you to specify network parameters on a server and have client computers query the server for their information such as IP, netmask, gateway, DNS, etc. In addition to not having to statically assign network information to numerous clients, you also do not need to specify the IP of the DHCP server as this discovery is done via broadcast packets; the caveat to this is that you must have one DHCP server per broadcast domain. In case it’s not blatantly obvious, the power of DHCP is that if anything changes on your network such as the IP of a DNS server, you only need to edit one configuration file even if you have hundreds of clients.

Setup a Linux VPN Server

I am assuming you are using a Redhat or Redhat-like distribution. Some of these packages can be grabbed via yum. However, I’m going to have you install them via RPM as you cannot get all of them via yum. If you are not, you will need to get the proper packages. For Debian you can use aptget or search for the .deb. For SuSe you can use Yast or find the distro specific RPMs.
