Rsync Error..

[Naveen Babu]

Hello,
I uncommented shell in inetd.conf on the destination system. 
 
The command " rsh 66.123.34.123 which rsync" is working fine now . 
I get the output /usr/local/bin/rsync. 
 
But the command: 
 
rsync -avvznrbe rsh /sourcepath 66.123.34.123:/destinationpath 
 
Still does not work. I get the same error as i used to get before.
 
opening connection using rsh 66.123.34.123 rsync --server -vvbnlogDtprz . /destinationpath
66.123.34.123: operation timed out
rsync: connection unexpectedly closed (0 bytes read so far)
rsync error: error in rsync protocol data stream (code 12) at io.c(189)

Thanks,
Naveen.

Ah! Now I've got you.
rsh without parameters does an rlogin, which uses the service commonly 
called "login", on port 513.
With parameters, it does a plain rsh, using the service commonly called 
"shell", on port 514.

Here's a system with both holes open (deep inside a well-protected 
intranet, host and usernames deleted to protect the innocent).

egrep "^shell|^login" /etc/services /etc/inetd.conf
/etc/services:login 513/tcp
/etc/services:shell 514/tcp cmd # no 
passwords used
/etc/inetd.conf:shell stream tcp nowait root /usr/sbin/in.rshd 
in.rshd
/etc/inetd.conf:login stream tcp nowait root /usr/sbin/in.rlogind 
in.rlogind

You probably have the shell line in inetd.conf commented out. open it, 
HUP inetd, and you're probably in business. No sane security guys could 
complain about shell if login is permitted.
I'm pretty sure that's your issue. It's also possible, of course, that 
you shell service is on an alternate port, or commented out of services. 
You'll see it, whatever it is.

All ssh sessions go through the sshd service, on port 22, and most systems 
that have one or the other of login and shell enabled have both. Yours is 
just an unusual case.

Hello,
when i gave "rsh 66.123.34.123 which rsync" at the source system i got the 
following error
66.123.34.123: Connection refused

"rsh 66.123.34.123" works perfectly fine.

What could be the problem..?
