Adam, what does /proc/sys/net/ipv6/bindv6only contain on your system?

approx calls bind() to in6addr_any, so I don't see why it would refuse
ipv4 connections if that sysctl is unset. It might be a good idea for
approx to explicitly set IPV6_V6ONLY to 0, though.
Hmmmm....in that case it should work. Oh, hang on, something else
changed for 3.1.0 didn't it....

Ah. My bad. I had a bad hosts.deny file. I didn't notice before as I
don't have anything running via inetd on the approx server, and set up
all access control with iptables instead.
Fixing my hosts.deny fixes the problem.
Yup. Next time, I must remember to describe what I did and what output I
got, not what my misdiagnosis of the problem was.
Sorry for wasting everyone's time.
