355: <br>
356: The MacOS installer shipped with OpenBSD 2.7 does not correctly make all
357: devices, specifically it does not make the <code>/dev/arandom</code> device
358: needed for the userland crypto such as ssh to work. The problem shows itself
359: when ssh-keygen fails to make RSA or DSA keys, resulting in messages like
360: <b>RSA-generate_keys failed</b> or <b>DSA-generate_keys failed</b>.
361: <br>
362: To work around this, once your machine is up and running run the following
363: commands as root:
364: <pre>
365: # cd /dev
366: # ./MAKEDEV arandom
367: </pre>
1.1 deraadt 368: <p>
1.96 deraadt 369: After doing this (and possibly installing one of the ssl27 packages),
370: reboot your machine and it will generate ssh keys correctly.
