For the notion of tradition I need to say that "all the information for educational purpose".
To make use of that trick, you should able to connect to the LAN but cannot connect to internet since it is waiting to fill a authentication form that is not free to fill(generally, if it is free don't mass your mind).
We follow the process as, first look the LAN for other hosts' IP addresses. Find a good looking IP (luckily connected to internet already.). Then retrieve the MAC address of that IP by using ARP protocol. Set your MAC address to retrieved one. Check whether you can surf. If you can't, try another victim IP.

See the current MAC values
erogol@erogol-G50V ~ $ ifconfig -a | grep Ethernet
eth0 Link encap:Ethernet HWaddr 00:22:15:3a:36:93
wlan0 Link encap:Ethernet HWaddr 00:15:af:dd:94:91
Stop running of the card
<pre ">erogol@erogol-G50V ~ $sudo ifconfig eth0 down
Change the MAC address
erogol@erogol-G50V ~ $ sudo ifconfig hw ether 00:22:15:3a:36:83
Start the card running again
erogol@erogol-G50V ~ $ sudo ifconfig eth0 up
That's all. You might see the new MAC address for check.
Why I need to change the MAC address. Continue reading Changing MAC address of your network cards on Linux
