In theory, the configure script should auto-detect IPv6 support (assuming --enable-ipv6), and Do The Right Thing(tm). In practice, most of the development environments I use have IPv6 support, so that I am not sure that the configure script actually _does_ this. If you have "UseIPv6 on" on a host with no IPv6 support, you might see more errors logged, e.g. when ProFTPD starts up, as it tries to bind/listen on IPv6 sockets. > I guess that IPv4 clients should be able to connect and transfer data > bidirectionally without problems, correct? Correct. By default, ProFTPD uses a local wildcard socket (e.g. "*:21"); such sockets transparently handle IPv4 and IPv6 connections. If you _do_ encounter issues/strange behavior with "UseIPv6 on" with an IPv4-only host, please do bring them up here. Obviously these issues can be worked around by using "UseIPv6 off" in the proftpd.conf, but I'd also like to make the code better handle such cases automatically.
