I looked through the source for libcurl and found that if the known hosts file name is not set (CURLOPT_SSH_KNOWNHOSTS), there is no default value and so the key function never gets called. Fair enough, but it seems odd that the other filename settings fall back to a default value if not explicitly set, yet the know hosts file name does not.

If I set the known hosts file name, my key function does get called (hooray!) but even when I return CURLKHSTAT_FINE, the authentication fails. Furthermore, when I return CURLKHSTAT_FINE_ADD_TO_FILE, writing to my hosts file fails, even though I believe the permissions are adequate (-rw-r--r--).

I must still be doing something wrong...
