rsync - Jul 2013 - [Bug 10031] New: rsyncd resolves hosts stupidly

https://bugzilla.samba.org/show_bug.cgi?id=10031

           Summary: rsyncd resolves hosts stupidly
           Product: rsync
           Version: 3.0.8
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P5
         Component: core
        AssignedTo: wayned at samba.org
        ReportedBy: jwz at jwz.org
         QAContact: rsync-qa at samba.org


rsyncd matches host names in the "hosts allow" line of rsyncd.conf
with reverse
lookups only. This fails when you don't have control over reverse DNS, which
is
common these days.

To save me from having to type IP addresses instead of host names into my
config file, please make it do forward lookups instead (or, in addition).  Call
gethostbyname on the items in "hosts allow" and compare those IPs
against the
incoming IP.

Thanks.

[Are insults really necessary?]
>From the rsync 3.1.0 manual:
forward lookup

Controls whether the daemon performs a forward lookup on any hostname specified
in an hosts allow/deny setting.  By default this is enabled, allowing the use
of an explicit hostname that would not be returned by reverse DNS of the
connecting IP.
