Alan Jenkins	8c38907016	Misconfigured DNS should not ban successful ssh logins Noticed while looking at the source (to see the point of ssh-ddos). POSSIBLE BREAK-IN ATTEMPT - sounds scary? But keep reading the message. It's not a login failure. It's a warning about reverse-DNS. The login can still succeed, and if it _does_ fail, that will be logged as normal. <exhibit n="1"> Jul 9 05:43:00 brick sshd[18971]: Address 200.41.233.234 maps to host234.advance.com. ar, but this does not map back to the address - POSSIBLE BREAK-IN ATTEMPT! Jul 9 05:43:00 brick sshd[18971]: Invalid user html from 200.41.233.234 </exhibit> The problem (in my mind) is that some users are stuck with bad dns. The warning won't stop them from logging in. I'm pretty sure they can't even see it. But when they exceed a threshold number of logins - which could be all successful logins - fail2ban will trigger. fail2ban shouldn't adding additional checks to successful logins - it goes against the name fail2ban :) - the first X "POSSIBLE BREAK-IN ATTEMPT"s would be permitted anyway - if you want to ban bad DNS, the right way is PARANOID in /etc/hosts.deny I've checked the source of OpenSSH, and this will only affect the reverse-DNS error. (I won't be offended if you want to check for yourself though ;) <exhibit n="2"> $ grep -r -h -C1 'ATTEMPT' openssh-5.5p1/ logit("reverse mapping checking getaddrinfo for %.700s " "[%s] failed - POSSIBLE BREAK-IN ATTEMPT!", name, ntop); return xstrdup(ntop); -- logit("Address %.100s maps to %.600s, but this does not " "map back to the address - POSSIBLE BREAK-IN ATTEMPT!", ntop, name); $ </exhibit>	13 years ago
