353: The MacOS installer shipped with OpenBSD 2.7 does not correctly make all
354: devices, specifically it does not make the <code>/dev/arandom</code> device
355: needed for the userland crypto such as ssh to work. The problem shows itself
356: when ssh-keygen fails to make RSA or DSA keys, resulting in messages like
357: <b>RSA-generate_keys failed</b> or <b>DSA-generate_keys failed</b>.
358: <br>
359: To work around this, once your machine is up and running run the following
360: commands as root:
361: <pre>
362: # cd /dev
363: # ./MAKEDEV arandom
364: </pre>
