Hi,
we had problems on FreeBSD-current. Attached is a patch we use on
FreeBSD-current. Find below the quote of the author of the patch. Maybe
it is possible to incorporate this patch into the next release of
rsync.
From [EMAIL PROTECTED]:
"It seems the daemon mode of rsync depends on an IPv4-mapped IPv6
address. Since an IPv4-mapped IPv6 address is off by default on
5-CURRENT, rsync doesn't listen on IPv4. Further, rsync has a bug
that it always listen on 1st entry's address of the result of
getaddrinfo() call. Please try attached patch. With this patch,
rsync listen on both an IPv4 and an IPv6."
Please Cc me since I am not on the list.
Regards,
Olli
