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