How to Block Websites & Stop Downloading Using Proxy


This example will explain you “How to Block Web Sites” & “How to Stop Downloading”.
First, Configure Proxy.
/ip proxy
set enabled=yes
set src-address=0.0.0.0
set port=8080
set parent-proxy=0.0.0.0
set parent-proxy-port=0
set cache-administrator=”webmaster”
set max-cache-size=none
set cache-on-disk=no
set max-client-connections=600
set max-server-connections=600
set max-fresh-time=3d
set always-from-cache=no
set cache-hit-dscp=4
set serialize-connections=no

Now, Make it Transparent
/ip firewall nat add chain=dstnat protocol=tcp dst-port=80 action=dst-nat to-addresses= to-ports=8080
Make sure that your proxy is NOT a Open Proxy
/ip firewall filter add chain=input in-interface= src-address=0.0.0.0/0 protocol=tcp dst-port=8080 action=drop
Now for Blocking Websites
/ip proxy access add dst-host=www.vansol27.com action=deny
It will block website http://www.vansol27.com, We can always block the same for different networks by giving src-address. It will block for particular source address.
We can also stop downloading files like.mp3, .exe, .dat, .avi,…etc.
/ip proxy access
add path=*.exe action=deny
add path=*.mp3 action=deny
add path=*.zip action=deny
add path=*.rar action=deny.
Try with this also
/ip proxy access add dst-host=:mail action=deny
This will block all the websites contain word “mail” in url.
Example: It will block www.hotmail.com, mail.yahoo.com, www.rediffmail.com

What is MikroTik RouterOS?


What is RouterOS?
MikroTik RouterOS is the operating system of MikroTik RouterBOARD hardware. It can also be installed on a PC and will turn it into a router with all the necessary features – routing, firewall, bandwidth management, wireless access point, backhaul link, hotspot gateway, VPN server and more.
RouterOS is a stand-alone operating system based on the Linux v2.6 kernel, and our goal here at MikroTik is to provide all these features with a quick and simple installation and an easy to use interface.
You can try RouterOS today, go to www.mikrotik.com and download the installation CD image. The free trial provides all of the features with no limitations. In the following pages you will find examples of some of the most important RouterOS features.
Configuration
RouterOS supports various methods of configuration – local access with keyboard and monitor, serial console with a terminal application, Telnet and secure SSH access over networks, a custom GUI configuration tool called Winbox, a simple Web based configuration interface and an API programming interface for building your own control application. In case there is no local access, and there is a problem with IP level communications, RouterOS also supports a MAC level based connection with the custom made Mac-Telnet and Winbox tools.
RouterOS features a powerful, yet easy to learn command-line configuration interface with integrated scripting capabilities.
• Winbox GUI over IP and MAC
• CLI with Telnet, SSH, Local console and Serial console
• API for programming your own tools
• Web interface
New in RouterOS v4 is the Lua scripting language, which opens up a multitude of approaches in automation and programming of your router.
Firewall
The firewall implements packet filtering and thereby provides security functions, that are used to manage data flow to, from and through the router. Along with the Network Address Translation it serves for preventing unauthorized access to directly attached networks and the router itself as well as a filter for outgoing traffic.
RouterOS features a stateful firewall, which means that is performs stateful packet inspection and keeps track of the state of network connections traveling across it. It also supports Source and Destionation NAT (Network Address Translation), NAT helpers for popular applications and UPnP.
The Firewall provides features to make use of internal connection, routing and packet marks. It can filter by IP address, address range, port, port range, IP protocol, DSCP and other parameters, also supports Static and Dynamic Address Lists, and can match packets by pattern in their content, specified in Regular Expressions, called Layer7 matching.
The RouterOS Firewall facility also supports IPv6.
Routing
RouterOS supports static routing and a multitude of dynamic routing protocols.
• For IPv4 it supports RIP v1 and v2, OSPF v2, BGP v4.
• For IPv6 it supports RIPng, OSPFv3 and BGP.
RouterOS also suppors Virtual Routing and Forwarding (VRF), Policy based routing, Interface based routing and ECMP routing. You can use the Firewall filter to mark specific connections with Routing marks, and then make the marked traffic use a different ISP.
Now with MPLS support added to RouterOS, VRF is also introduced. Virtual Routing and Forwarding is a technology that allows multiple instances of a routing table to co-exist within the same router at the same time. Because the routing instances are independent, the same or overlapping IP addresses can be used without conflicting with each other. VRF also increases network security. It is often used in, but not limited to MPLS networks.
MPLS
MPLS stands for MultiProtocol Label Switching. It can be used to replace IP outing – packet forwarding decision is no longer based on fields in IP header and routing table, but on labels that are attached to packet. This approach speeds up forwarding process because next hop lookup becomes very simple compared to routing lookup.
Efficency of forwarding process is the main benefit of MPLS. MPLS makes it easy to create “virtual links” between nodes on the network, regardless of the protocol of their encapsulated data.
It is a highly scalable, protocol agnostic, data-carrying mechanism. In an MPLS network, data packets are assigned labels. Packet-forwarding decisions are made solely on the contents of this label, without the need to examine the packet itself. This allows one to create end-to-end circuits across any type of transport medium, using any protocol.
Some of the supported MPLS features:
• Static Label bindings for IPv4
• Label Distribution protocol for IPv4
• RSVP Traffic Engineering tunnels
• VPLS MP-BGP based autodiscovery and signaling
• MP-BGP based MPLS IP VPN
VPN
To establish secure connections over open networks or the Internet, or connect remote locations with encrypted links, RouterOS supports various VPN methods and tunnel protocols:
• Ipsec – tunnel and transport mode, certificate or PSK, AH and ESP security protocols
• Point to point tunneling (OpenVPN, PPTP, PPPoE, L2TP)
• Advanced PPP features (MLPPP, BCP)
• Simple tunnels (IPIP, EoIP)
• 6to4 tunnel support (IPv6 over IPv4 network)
• VLAN – IEEE802.1q Virtual LAN support, Q-in-Q support
• MPLS based VPNs
This means that you can securely interconnect banking networks, use your workplace resources while travelling, connect to your home local network, or increase security of your wireless backbone link. You can even interconnect two branch office networks and they would be able to use each other’s resources, as if the computers would be in the same location – all secure and encrypted.
Wireless
A variety of Wireless technologies are suppored in RouterOS, the most basic of them being the wireless access point and client. If it’s a small hotspot network in your home, or a city wide mesh network, RouterOS will help you in all situations.
Some of the features supported by RouterOS:
• IEEE802.11a/b/g/n wireless client and access point
• Nstreme and Nstreme2 proprietary protocols
• Client polling
• RTS/CTS
• Wireless Distribution System (WDS)
• Virtual AP
• WEP, WPA, WPA2 encryption
• Access control list
• Wireless client roaming
• WMM
• HWMP+ Wireless MESH protocol
• MME wireless routing protocol
RouterOS also features the NStreme proprietary wireless protocol that allows to extend the connection range and speed, when using MikroTik routers at each end. This has helped to achieve the current non-amplified wifi link lenght world record in Italy. Also supported is NSteme dual which allows to use two antennas at each end, one for receiving and one for sending.
HotSpot
The MikroTik HotSpot Gateway enables providing of public network access for clients using wireless or wired network connections. The user will be presented a login screen when first opening their web broswer. Once a login and password is provided, the user will be allowed internet access. This is ideal for hotel, school, airport, internet cafe or any other public place where administration doesn’t have control over the user computer. No software installatin or network configuration is needed, hotspot will direct any connection request to the login form.
Extensive user management is possible by making different user profiles, each of which can allow certain uptime, upload and download speed limitation, transfer amount limitation and more.
Hotspot also supports authentication against standard RADIUS servers and MikroTik’s own User Manager which will give you a centralized management of all users in your networks.
• Plug-n-Play access to the Network
• Authentication of local Network Clients
• User Accounting
• RADIUS support for Authentication and Accounting
• Configurable bypass for non-interactive devices
• Walled garden for browsing exceptions
• Trial user and Advertisement modes
Quality of Service
Bandwidth Control is a set of mechanisms that control data rate allocation, delay variability, timely delivery, and delivery reliability.
Quality of Service (QoS) means that the router can prioritize and shape network traffic. Some features of MikroTik RouterOS traffic control mechanism are listed below:
• limit data rate for certain IP adresses, subnets, protocols, ports, and other parameters
• limit peer-to-peer traffic
• prioritize some packet flows over others
• use queue bursts for faster web browsing
• apply queues on fixed time intervals
• share available traffic among users equally, or depending on the load of the channel
RouterOS supports Hierarchical Token Bucket (HTB) QoS system with CIR, MIR, burst and priority support, and provides both advanced queuing, and also an easy solution for basic QoS implementation – Simple queues.
Web Proxy
RouterOS features a MikroTik custom made proxy server for caching web resources, and speeding up customer browsing by delivering them cached file copies at local network speed. MikroTik RouterOS implements the following proxy server features:
• Regular HTTP proxy
• Transparent proxy
• Access list by source, destination, URL and requested method (HTTP firewall)
• Cache access list to specify which objects to cache, and which not.
• Direct Access List to specify which resources should be accessed directly, and which – through another proxy server
• Logging facility
• SOCKS proxy support
• Parent proxy support
• Cache storage on external drives
RouterOS can also act as a Transparent Caching server, with no configuration required in the customer PC. RouterOS will take all HTTP requests and redirect them to the local proxy service. This process will be entirely transparent to the user, and the only difference to them will be the increased browsing speed.
Tools
To help administrating your network, RouterOS also provides a large number of small network tools to optimize your everyday tasks. Here are some of them:
• Ping, traceroute
• Bandwidth test, ping flood
• Packet sniffer, torch
• Telnet, SSH
• E-mail and SMS send tools
• Automated script execution tools
• CALEA data mirroring
• File Fetch tool
• Active connection table
• NTP Client and Server
• TFTP server
• Dynamic DNS updater
• VRRP redundancy support
• SNMP for providing graphs and stats
• RADIUS client and server (User Manager)

Install Apache Web Server on Ubuntu


This step-by-step howto shows a basic setup for Apache 2 web server. Apache is installed on Ubuntu 6.06 LTS Dapper, but instructions will probably work on any Ubuntu. This document is a work in progress, initially only required commands are listed without troughout explanations.
© 2006 Tero Karvinen. GNU General Public License, version 2.
Install Apache
$ sudo apt-get install apache2
Test it
Surf to your own server on your own local computer:
$ firefox “http://localhost”
Find out how your server is found on the net. Anyone can use your IP address or DNS name to connect to your server:
$ ip addr
Use your own IP address (eth0, first IP number, does not end .255)
$ firefox “http://1.2.3.4″
If DNS is working on your network, you can see your fully qualified domain name with:
$ host 1.2.3.4
User homepages
With user homepages, anything you put in public_html in your home directory is published on the web.
Enabling Userdir on Server
For newer Ubuntu such as 8.04 Hardy, you have to explicitly enable userdir module. On older ones such as 6.06 LTS Dapper, userdir is enabled by default.
$ sudo a2enmod userdir
$ sudo /etc/init.d/apache2 restart
Test homepages
Go to your home directory
$ cd
Create a folder for public html files, note the underscore ‘_’
$ mkdir public_html
Check your name
$ whoami
Surf to ~yourname:
$ firefox “http://localhost/~tkarvine/”
You should see a directory listing of an empty directory. You can also try it using your IP address and a different machine.
If you see your homepage, well done. You have successfully installed a server with user homepages. You can create some web pages with OpenOffice and save them to your public_html directory.

Learn to Make Banner Ads



Banner ads, and if used correctly, can bring many benefits to the organization. With the current competition in the field of marketing on the Internet, and can be one source of banner ads targeted leads and make more sales potential that can generate income part-time, to say the least.
