rsync - Jun 2004 - Daemon + ipv6 bug report

Hi all.

I'm just reporting some strange (fatal) behaviour when running
rsync --daemon on an IPv6-enabled box. It gets a fatal error
when trying to bind to the same address twice.

strace output:

bind(4, {sa_family=AF_INET6, sin6_port=htons(873), inet_pton(AF_INET6,
"::", &sin6_addr), sin6_flowinfo=0, sin6_scope_id=0}, 28) = 0
bind(5, {sa_family=AF_INET, sin_port=htons(873),
sin_addr=inet_addr("0.0.0.0")}, 16) = 0
listen(4, 5)                            = 0
listen(5, 5)                            = -1 EADDRINUSE (Address already in use)

The workaround is very simple; use --address 0.0.0.0 (or "::") to keep
it
from binding twice.

Thanks,
Vidar

This should only affect older systems that don't have a proper IPv6
implementation, such as some older 2.4 Linux kernels.  The fix that I
suggested earlier is to use either the -6 or the -4 option to tell
rsync to only bind only one of the duplicitous addresses.
