Hello.

Thank you, you saved me from going insane. There was a wildcard DNS
entry, and my hostname (say, “ivanov”) was first resolved as
“ivanov.spb.ru MX <some-global-ip>”, instead of “nmblookup ->
<some-local-IP>”.

So the only remaining problem is with the truly unresponsive rsyncd,
on the Windows 7 box. Can't connect even from localhost. Either I
missed a firewall/antivirus setting somewhere, or the rsyncd doesn't
like Windows 7 (and it is even 32-bit).

Sincerely,
Maxim
