Hii All,
      I'm really a linux newbie, I managed to run into a problem with  
rsync. I want to conduct backups of various files and directories over  
about miles of Internet, so I chose ssh and rsync for the job.
         Earlier it used to work fine, but suddenly donno what  
happened it started to show the following errors

Here's the command that runs rsync on the client:
rsync -rlt /data/DData /media/usbdisk

As you can see from the above output, I can connect and the errors start.

Any help/indications would be appreciated.

With Regards,
Ram
