I have a MacBook which is connected to the net via an ancient DSL router (NAT enabled). I want to SSH into the server from elsewhere, but my ISP assigns new IP address every once in a while.
I would like to use a dynamic DNS service for "finding" my Mac, but the router does not support any dynamic DNS functionality.
What (lightweight) option is there to update the DNS service with current IP info anyway? I remember installing a clunky menu-bar app several years ago, and I would prefer something configurable from the terminal.
NB: I feel it could be a problem when the MacBook is moved to a different network (friends, company) temporarily and attempts to connect to macbookaddress.dynamicdnz.tld suddenly hit their network. Correct?
