DO NOT REPLY [Bug 5411] New: rsyncd.conf allow does not like CNAME
https://bugzilla.samba.org/show_bug.cgi?id=5411
Summary: rsyncd.conf allow does not like CNAME
Product: rsync
Version: 2.6.9
Platform: Other
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P3
Component: core
AssignedTo: wayned@samba.org
ReportedBy: marc@perkel.com
QAContact: rsync-qa@samba.org
When using rsyncd.conf - if the host allow uses a host name and when the FCrDNS
of the host name is verified, if the reverse pointer references a CNAME - it
doesn't work. The following fails.
hosts allow = *.ctyme.com
Example:
65.49.42.30

------- Comment #1 from wayned at samba.org 2011-01-03 21:21 CST -------
The 3.1.0dev version will now support a CNAME for a host as long as you list
the hostname(s) explicitly (i.e. don't try to wild-card match a CNAME).
Wildcard matching can only work against the reverse-DNS name of the connecting
IP, since there is no good way to ask for all the IPs that match a wildcard
hostname.
Example:
hosts allow = bar.foo.com
That will allow host baz.foo.com to connect if bar.foo.com is a CNAME for
baz.foo.com
