oh, you said surf which implies http. OK, I don't think there are machines on the Internet just sitting there waiting for you to telnet to them so you can hop to another machine. Maybe 10 years ago. These days telnet is one of the biggest security breaches you could possibly expose. Thats why practically nobody exposes it any more, if anything they would use SSH. But again, good luck finding anyone that will allow someone they don't know on their machine.
