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

1.96 deraadt 362: After doing this (and possibly installing one of the ssl27 packages),
363: reboot your machine and it will generate ssh keys correctly.
