Computer Tips - I get: Address IP-address maps to Domain-Name, but this does not map back to the address - POSSIBLE BREAK-IN ATTEMPT!
Date: 2012may8 OS: Linux Product: scp, ssh, openssh-clients Q. I get: Address <IP-address> maps to <Domain-Name>, but this does not map back to the address - POSSIBLE BREAK-IN ATTEMPT! When I try to scp or ssh to a certain IP-address. What should I make of this? A. ssh and ssh usually work so flawlessly for moving data about we sometimes forget they are also about security. Literally this error means that ssh did a reverse lookup on that that IP-address and got <Domain-Name>. Then it did a regular lookup on <Domain-Name> but got an IP-address different than the original IP-address. OK, but what does mean practically? This is ssh being paranoid -- which is fine that's its job. But if you were given an IP-address and told that was where you could scp some files normally I would not worry about this error. The "fingerprint changed" error is more of a red flag.
