copied!<p><strong>UPDATE - FIXED IT</strong></p> <pre><code>restorecon -R -v -d /root/.ssh </code></pre> <p>This is a known issue with RH where directories get mislabelled and PAM prevends sshd from reading authorized_hosts when run as init script. You'll see the errors if you stumble across <code>/var/log/audit/audit.log</code>. Rare it seems but painful when it happens!</p> <p>More details at <a href="https://bugzilla.redhat.com/show_bug.cgi?id=499343" rel="nofollow">https://bugzilla.redhat.com/show_bug.cgi?id=499343</a></p> <p><strong>ORIGINAL POST</strong></p> <p>I've just hit what looks like exactly this problem. I had a poorly tuned VirtualBox (I hadn't told vbox to use 64bit) -- which when I cloned and restarted (in vbox RedHat 64-bit mode), started asking me for a password.</p> <p>The original image was fine -- with identical settings -- so I think the suggestion of being networking-related might be relevant, or else to do with server keys.</p> <p>The weird thing however is that if on the box, I kill the sshd process which autostarted, then manually run /usr/sbin/sshd as root, I can log in passwordless fine. <strong>A silly workaround, but usable.</strong></p> <p>So it is an /etc/init.d/sshd issue. But I haven't been able to track down what it is ... have tried chucking out most of the stuff in that script but it still prompts for password when invoked as <code>/etc/init.d/sshd start</code> but not when at <code>/usr/sbin/sshd</code>.</p> <p>Maybe these comments can help, and someone can then help further!?</p>
