Hello, maybe someone could please help and shed some light on a problem that i don't understand, and that even in multiple ways. The problem occurred three or four times over the past months (maybe half a year?) and manifests as ++ Pushing to "gitlab" (at least "master" differs)! Warning: Permanently added the RSA host key for IP address '104.46.105.89' to the list of known hosts. I get no confirmation prompt, which i normally do?! Of course i do have a configuration file with an UserKnownHostsFile ~/arena/data/ssh/known_hosts entry, and that already has a gitlab.com,54.93.71.23 DATA line for months. I do have a "Host" entry for "*gitlab.org" (with explicit IdentityFile). The entry in known_hosts that i (hope to have confirmed correctly back then) is not identical with the other two entries, but which are, except for the addresses --- k.1 2015-10-09 18:09:10.511793883 +0200 +++ k.2 2015-10-09 18:09:26.508373888 +0200 @@ -1,2 +1,2 @@ -52.21.36.51 +104.46.105.89 ssh-rsa ... I understand that the keys in k.1 and k.2 are the same that ssh-keyscan(1) gives me, whereas the address i verified does currently give no ssh-keyscan result at all. (I verified it back in the day in that i was able to login after placing my public key at their server via a HTTPS connection after i had created my account. I'm no expert in mathematics or the SSH protocols, but i'm confident as only a greenhorn or real expert can be.) So: no confirmation prompt, no hostname but only the address for the entry in known_hosts even though the connection is to gitlab.com (they're appended though), and multiple entries with the same key. I'm on "OpenSSH_7.1p1, OpenSSL 1.0.2d 9 Jul 2015". Thank you in advance for any hint, ciao, --steffen _______________________________________________ openssh-unix-dev mailing list openssh-unix-dev@xxxxxxxxxxx https://lists.mindrot.org/mailman/listinfo/openssh-unix-dev
