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

1.96 deraadt 364: After doing this (and possibly installing one of the ssl27 packages),
365: reboot your machine and it will generate ssh keys correctly.
