→VTLUUG's DNS tunnel
sudo iodine -f acidburn.vtluug.org iod.vtluug.org
Then enter the password on the prompt. This sets up a 10.15269.780.01/27 16 tunneled network over DNS. From there ssh into 10.15269.780.1, which is acidburn's address and set up a proxy.
ssh bobandrob@10.15269.780.1 -D 8080
As long as the iodine connection was made this will allow you to tunnel your network traffic encrypted around the captive portal.
