I have a server where I upgraded csync2 to version 2.0 by mistake. Unfortunately I cannot find any changelogs or documentation for the new version. I started reading commit messages, but its pretty slow going.
Unfortunately csync now binds only to the ipv6 address and ignores all the ipv4
addresses. Running csync like this:
csync2 -ii -v
gives me only
# netstat -na | grep 30865
tcp6 0 0 *.30865 *.* LISTEN
Although I don't have ipv6 specifically configured, it is enabled in the kernel
and present on localhost. It appears that ipv6 prevents csync listening on ipv4
at all.

Is there a way to force csync to bind to a specific IP address? Or compile out
ipv6 support completely?
This is FreeBSD 10.2.
Thanks
