Surfing access the DNS

Most airports, hotels and the like places, when you enter a URL such as www.google.com, it will pop up a page to enter your account password to access. DNS can be resolved correctly this time, but the Internet to pay for certification.

DNS tunneling can be achieved through free Internet access. Specifically:

(1) try to get a domain name DNS resolution, and now many of these free domain name, such as the tk, co.cc's. Assuming that the domain name is abc123.tk.

(2) the registration of institutions in tk, set abc123.tk the NS server for your own host (preferably Linux VPS), for example:
abc123.tk. IN NS ns.abc123.tk.
ns.abc123.tk. IN A 74.81.81.81

(3) 74.81.81.81, and as root run a Perl script (the script from Dan Kaminsky's OzymanDNS package):
. / nomde.pl-i 0.0.0.0 abc123.tk
The script listens on UDP 53 port, accept DNS requests, and only resolved abc123.tk domain.

(4) on the client machine (requires ssh, preferably Linux), run the following command:
ssh-ND 7070-o ProxyCommand = ". / droute.pl sshdns.abc123.tk" user @ localhost
The ssh command,-ND 7070, said the local open port 7070 for socks 5 proxy. droute.pl is a DNS tunnel client tool, also from OzymanDNS package. sshdns is fixed host name, domain name abc123.tk added to the front. user is your login name on the 74.81.81.81, @ localhost is fixed, do not change (because the tunnel is over, the machine is 74.81.81.81).

After running the ssh command will prompt for a password. Enter the correct password, you and the remote host established ssh connection, access to an SSH terminal. And, in 7070 opened the machine's socks 5 proxy port. Configure your browser to use this proxy port, began to enjoy free surfing it!
