Hi,

easiest way to prevent doubles is checking the process list. E.G. create a bash-script for your mirroring, that checks if there is already a connection to msync.centos.org::CentOS

---- SNIP ---- #!/bin/bash

if [ "$(ps auxw|grep msync.centos.org::CentOS|grep -v grep" != "" ];then

A better condition would be:

pgrep -f "rsync -options msync.centos.org ..." >/dev/null if [ $? -eq 1 ]; then echo "You should start the mirror, no sync in progress" else echo "Another sync is in progress" fi

...but this is begining to be a shell programming issue more than a mirror-setup thingie.
