[Csync2] ipv6 problems

[Aristedes Maniatis]

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
