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

1.96 deraadt 365: After doing this (and possibly installing one of the ssl27 packages),
