I inquired about this earlier but have not found a solution. I recently turned on compter-to-computer networking in airport and I think it changed my hostname. The computer that was hosting the comp-to-comp airport network is also within a network that automatically assigns my IP though DHCP. Now instead of having my original IP address as my hostname I have a DHCP-183-35 name assigned. I see this in the sharing pane, terminal, etc and if I use remote login, afp, and ssh. I can still connect if I use my IP address but am getting a warning error: "ssh firstname.lastname@example.org reverse mapping checking getaddrinfo for dhcp-100-35.tubooe.edu failed - POSSIBLE BREAKIN ATTEMPT!" can someone tell me how I go about getting back to just my IP address instead of the dhcp-100-35 naming? thanks.
