Rsync gives an rsh error when running in a script

Hi all,

This is a strange error that I only get from my Mandrake machines.
My FreeBSD and CentOS servers work fine.
I believe my syntax is correct in my script as well.

I have 3 servers installed with:
Mandrake Linux release 9.2 (FiveStar)
Kernel 2.4.26-mdkmosixsmp

I run my rsync in a script, which looks as follows:

Code:

#!/bin/bash

VAULT='backupserver'
RSYNC=`which rsync`
DATE=$(date +%Y-%m-%d.%H:%M)
LOG="/tmp/Server1-$DATE.log"

$RSYNC -avl --delete --stats /usr/local/data root@$VAULT:/Backups/Server1 >> $LOG

When I run this script, all 3 servers give me the same error:

Quote:

Failed to exec rsh : No such file or directory
rsync error: error in IPC code (code 14) at pipe.c(82)
rsync: connection unexpectedly closed (0 bytes read so far)
rsync error: error in rsync protocol data stream (code 12) at io.c(165)

My rsync is located in "/usr/bin/rsync" which is in my path.

I tried to run the command manually but I get the same errors.

Is it something I have to install ?

I do not know Mandrake very well, I actually am not even too sure how to install anything on Mandrake.

Thanks for the help.

As per the man page:

You can also specify any remote shell you like, either by using the -e
command line option, or by setting the RSYNC_RSH environment variable.

rsync needs to use some remote shell to connect to remote machines. These days that is normally ssh by default, but is seems that on your installation it is trying to use rsh. As pointed out by kbp, you can choose which remote shell using the -e flag or RSYNC_RSH variable. For example to use ssh (which is probably what you want) do:

Code:

$RSYNC -e ssh -avl --delete --stats /usr/local/data root@$VAULT:/Backups/Server1 >> $LOG

Although, I don't recommend allowing root ssh access.
