Can you please post here output of the following commands? (executed on machine where ssh prints warnings) # dig leptop.alonandeinat.local +dnssec # dig -x 192.168.1.100 +dnssec This will tell us if forward and reverse lookups are really correct. Thanks in advance. dig leptop.alonandeinat.local +dnssec provide : [dotanalon@serverhome ~]$ dig leptop.alonandeinat.local +dnssec ; <<>> DiG 9.7.4b1-RedHat-9.7.4-0.3.b1.fc14 <<>> leptop.alonandeinat.local +dnssec ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 60259 ;; flags: qr aa rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 1, ADDITIONAL: 2 ;; OPT PSEUDOSECTION: ; EDNS: version: 0, flags: do; udp: 4096 ;; QUESTION SECTION: ;leptop.alonandeinat.local.

Reassigning to openssh for further inspection, it seems like a bug in the ssh client or in the glibc resolver. What prints 'getent hosts 192.168.1.100' ? getent hosts 192.168.1.100 provides the following : [dotanalon@serverhome ~]$ getent hosts 192.168.1.100 192.168.1.100 leptop.alonandeinat.local This package has changed ownership in the Fedora Package Database. Reassigning to the new owner of this component. This message is a notice that Fedora 14 is now at end of life. Fedora has stopped maintaining and issuing updates for Fedora 14. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At this time, all open bugs with a Fedora 'version' of '14' have been closed as WONTFIX. (Please note: Our normal process is to give advanced warning of this occurring, but we forgot to do that. A thousand apologies.) Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, feel free to reopen this bug and simply change the 'version' to a later Fedora version. Bug Reporter: Thank you for reporting this issue and we are sorry that we were unable to fix it before Fedora 14 reached end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged to click on "Clone This Bug" (top right of this page) and open it against that version of Fedora. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping |
