Technologies Net Alliance (TNA), launching 2 days Open Source Training on Squid PROXY Server Administration course for IT professionals and system administrators.
OVERVIEW OF THE TRAINING
Participants will be trained to set up and configure a Squid Proxy Server. Squid is one of the most popular and most used proxy servers in the world. It is free to download and can be implemented on any distribution of Linux. It is a full-featured web proxy cache server application which provides proxy and cache services for Hyper Text Transport Protocol (HTTP), File Transfer Protocol (FTP), including basic PC-based routing and firewalling techniques. Proxy servers are commonly used in computer networks to protect the network from attack, to filter undesirable web content and web pages requested by local users, and to speed up the delivery of web pages and web content by caching (storing) commonly requested web pages, documents, and media. Proxy servers are typically implemented on private, local area networks, to filter, protect and cache content requested by users on that network, this is called "proxy" or "transparent proxy.
TYPES OF PROXY SERVERS
The web browser on the client is configured to point to the proxy server's IP address. The client can bypass the proxy server by removing or altering the proxy address configuration. An administrator could prevent this by creating a GPO in Active Directory that blocks access to the web browser settings. A proxy server can also function as a caching server.
Transparent Proxy Server:
The router sends all traffic on defined ports, to the transparent proxy server, this way clients cannot bypass the proxy server. A transparent proxy server can also function as a caching server.
Reverse Proxy Server (Cache):
The reverse proxy server or cache server is placed in-front-of or prior-to the web server in order to speed up delivery of frequently requested pages and to protect the web server by creating a layer of separation and redundancy.
