How can I secure connections between linux/unix rsync clients and cwRsync servers ?

On Windows: 

  • Install Copssh and cwRsync server. Use the same service account.
  • Start RsyncServer and OpenSSHD services
  • Activate a user
  • Import your public key via Copssh Control Panel:

    •  Make sure that the user and the service account has write access to c:\backup
    • Add a new module to rsyncd.conf :
[backup]
path = /cygdrive/c/backup
read only = false
transfer logging = yes

 

On Linux:

  • Use shell script below after having it updated according to your needs:
#!/bin/bash
localport=9119
remoteport=873
remotehost=192.168.100.21
rsyncmodule=backup
remoteuser=lab1user
sourcedir=/bin/

echo Establishing secure channel ...
ssh -L $localport:127.0.0.1:$remoteport $remoteuser@$remotehost -T -N -f

rsync -vrt $sourcedir rsync://localhost:$localport/$rsyncmodule

echo Terminating secure channel ...
ps ax | grep "ssh -L $localport" | awk '{print $1}' | xargs -i kill {} 2&>/dev/null
