FW: Rsync issue

[Rajeev Jain]

I have setup 2 servers with the rsync
# /etc/services
rsync           6873/tcp                        # Rsync Server

# /etc/inetd.conf
rsync stream tcp nowait root /usr/local/bin/rsync rsyncd --daemon

Looks like they work internally but not remotely. Please read below the 2
examples

This works:
bash-2.05$ /usr/local/bin/rsync -avz  -e ssh /tmp/5.0 /tmp/5.0
building file list ... done
wrote 83428 bytes  read 20 bytes  33379.20 bytes/sec
total size is 85086768  speedup is 1019.64

ERROR:
bash-2.05$ /usr/local/bin/rsync -avz  -e ssh /tmp/5.0 rajeevj at sun1:/tmp/5.0
rajeevj at sun1's password:
rsync: connection unexpectedly closed (0 bytes read so far)
rsync error: error in rsync protocol data stream (code 12) at io.c(165)

Could you guys please suggest what this error means?
