I've been given some help in this offline. Apparently, the bacula code is incorrectly using hosts_access. bacula should fork before it calls hosts_access because hosts_access will kill you on twist. Otherwise, you'll get either a deny or an allowed, and the thread continue from here. My offline helper was comparing the inetd source code. I can't find any reference in host_options(5) or host_access(3) which point to the correct usage. Is the FreeBSD documentation incomplete? Is there a more accurate documentation I can point the bacula developers to? FYI: The bacula approach is said to work under Linux and Solaris but I have yet to run my reproducible tests on those platforms. Thank you. -- Dan Langille : http://www.langille.org/
