Created attachment 2760 [details] building log Hi. I have problem with openssl-7.1p1 building. It give me this error 'Saving key "/etc/ssh/ssh_host_key" failed: unknown or unsupported key type'. Any idea? Thanks
I'have no problem with 6.x versions
Openssh-7.x obsoletes SSH 1 protocol, which means it does not know anything about the old key format. You are probably using some build-script that counts with them and generates them during the build time. This is not a bug in openssh, but in your build script and there is no way to troubleshoot it, when you post only the log, but not the script or things you made to achieve such results.

After installation I don't do anything. When I'm trying to connect only with password authentication, the server refuse it. Thanks

I can reproduce your results with openssh-7.1p1, but not with current HEAD. Anyway, it is not a error, but only non-fatal warning since such a key is not useful for anything. This problem is basically duplicate of bug #2459 and was actually fixed in this commit and will be in the next release: https://anongit.mindrot.org/openssh.git/commit/?id=cfffbdb10fdf0f02d3f4232232eef7ec3876c383 The non-working authentication is different issue, but to investigate it, you should check for errors in the server log.
Thanks. SOLVED I run sshd in debug mode (sshd -d). Root login with password was enable in 6.x versions. In 7.x releases I had to set in sshd_config 'PermitRootLogin yes'. I'm sorry and I thanks for the time. I'm compiling an S.O. from source and I'm testing the applications from root account too.
Close all resolved bugs after 7.3p1 release
