Malformed Address and Private IP issue

[Jonathan Chen -X (jonachen - The Armada Group, Inc. at Cisco)]

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?
