Denyhosts - other options?

Howdy,

Using Denyhosts on Linux has worked well for me.  On Solaris I'm not
getting the results I expect.  It seems to be a problem deeper than
REGEXP.

Looking at the Denyhosts project, it has not been updated in many years
and the participation in the mailing list is next to nothing.  It makes
me wonder if other admins are quietly using something else
I don't know of.

What do other Solaris admins use to block brute force ssh attempts?

I've heard of fail2ban and sshblock.  There are reports of injected log data
in the media.  Have admins switched to a ip filter method?

I can summarize to the list if there are some good responses.
