We are testing CWRsync between a Windows 2003 SP1 and Windows XP Pro over an IPSEC tunnel between Netopia router and regularly receiving the errors:
2006/12/16 14:18:51  rsync: read error: Connection reset by peer (104)
2006/12/16 14:18:51  rsync error: error in rsync protocol data stream (code 12) at io.c(604) [receiver=2.6.9]
2006/12/16 14:18:51  rsync: connection unexpectedly closed (55922 bytes received so far) [generator]
2006/12/16 14:18:51  rsync error: error in rsync protocol data stream (code 12) at io.c(453) [generator=2.6.9]
It seems to happen whenever the tunnel is refreshing it's IKE encryption. We tested it over an PPTP tunnel and that worked OK. We don't want to use PPTP due to security reasons.
The command used is rsync --verbose -r --append --delete -z --progress --timeout=1200 /cygdrive/d/data/ 10.19.19.122::reclamebord/data
Any tips and trickz are welcome!
