I recently added a dyndns entry to enable remote access to my home PC. After about five minutes my firewall blocked the first access attempts to telnet (do intelligent people still use that?) and ssh. Strange, as I didn’t publish that DNS entry at all.
Anyway, let me welcome my first three scanners from user.veloxzone.com.br, brasiltelecom.net.br and saigonnet.vn. You don’t win anything though.
