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