rsync - Mar 2006 - Malformed Address and Private IP issue

Hello all,

I've run out of of ideas as to why its not working.   Below is my
configuration for hosts allow.   Even when I have 'hosts allow' off, it
still doesn't work.

Rsync host
=========rsync  version 2.5.7  protocol version 26

/etc/rsyncd.conf
hosts allow = 10.17.44.84 10.17.44.85 localhost.localdomain
dev-01.foo.com e-lnx.foo.com 

Server has 2 IP
eth0 = Inet IP
eth1 = Private IP

Rsync log
========2006/03/06 14:28:28 [28327] malformed address localhost.localdomain
2006/03/06 14:28:28 [28327] malformed address dev-01.foo.com
2006/03/06 14:28:28 [28327] rsync denied on module testdir from
stage-02.bar.com (10.17.44.85)

Client host -- stage-02.bar.com
==============Error msg:
@ERROR: access denied to testdir from stage-02.bar.com (10.17.44.85)
rsync: connection unexpectedly closed (92 bytes read so far)
rsync error: error in rsync protocol data stream (code 12) at io.c(165)


If I connect from other Inet IP, rsync works like a charm.   Just that
somehow it doesn't work with private IP or I misconfigured somehow.
Anyone what the case of my problem is?

I'd suggest upgrading to at least 2.6.6:  the error messages that a
daemon logs for login failures has improved, which should reveal exactly
why the connection is failing to authorize.  Also, some bugs have been
fixed that should hopefully get rid of the "malformed address"
warnings.

I've tried to use all IP for hosts allow and that does not work either.
It is so strange.  The Malformed address error only happens with private
ip and not the INET ip.

==Update
==After further investigation, I've found eth1(private ip) uses the same
gateway as eth0(INET ip).  The gateway ip is an INET ip which might
explain why I am getting malformed address???

Yeah heard of it to upgrade.  Not sure if possible for me to ask for
upgrade on the system I'm working on.

How important is it to type "make install" when I don't wish for
the
compiled program install into its default location.  I only want it to
be in in the compiled directory and read rsyncd.conf file.

So when I ran 2.6.6 under "sudo ./rsync --daemon
--config=/etc/rsyncd.conf" under RHEL 3, I basically get the same error
message.

I got rid of "hosts allow =" line  and I still get "malformed
address"
in the rsync.log file.   Then a deny of connection from X private
address.


sudo ./rsync -e ssh --archive --sparse --compress --update --progress
--stats -vv --dry-run jonachen@dev1::testdir  .

opening connection using --server --sender -vvunlogDtprSz . testdir 
@ERROR: access denied to testdir from stage02.foo.com (10.10.10.11)
rsync error: error starting client-server protocol (code 5) at
main.c(1171)

Cool.  Did that and it did not work.  After I compiled the new version
of rsync, I killed the old rsync -daemon and ran the new version.   Then
I used the new version to get 'testdir' module and still get the access
denied error message while the rsync.log complains about...

2006/03/08 11:25:12 [16976] malformed address localhost.localdomain
2006/03/08 11:25:12 [16976] malformed address dev01.foo.com (rsync
server name)
2006/03/08 11:25:12 [16976] rsync denied on module testdir from
stage02.foo.com (10.10.10.11)

"hosts allow" is turned off globably.   So I "should" not
get a denied
message in the rsync.log.
