Okay so it sounds like there's two separate issues here: 1) The issue with rbldnsd not working for you on RELENG_7 (returning REFUSED and some other oddities), 2) When assigning an IP to lo0 on your RELENG_7 box, the netmask chosen is 255.255.255.255 (0xffffffff) instead of 255.0.0.0 (0xff000000), even though for everyone else this isn't happening. :-) You've made a hackfix for the issue in #2 by explicitly putting the following line in your /etc/rc.conf: ifconfig_lo0="inet 127.0.0.1 netmask 255.0.0.0" Which also appears to resolve issue #1, is that correct? If that's true, there is greater demons at work here, or something we aren't being told about the configuration. Again, the IPs in rbldnsd zone files have nothing to do with IP addresses or netmasks associated with loopback, so I don't see how changing the netmask would fix that. It almost sounds as if the rbldnsd software may be written to assume they're all related, and I sure hope that isn't the case. -- | Jeremy Chadwick jdc at parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.
