What do you want to rsync from where to where?

It is really easy to set up - in fact I just got done writing an internal wiki page on how to do a simple setup.

The following is what I use for my kickstart servers so the main server can rsync itself out to slave servers. This sets up /var/www/html/ks on the slave server as an rsync share that the master can write to

/etc/rsyncd.secrets ---snip--- kickstart:user ---snip---

This file must be set to permissions 0600

and the main config file

/etc/rsyncd.conf

Here we use a subdirectory of the main default Apache directory which is /var/www/html ---snip--- # Set this if you want to stop rsync daemon with rc.d scripts pid file = /var/run/rsyncd.pid log file = /var/log/rsyncd.log

# Edit this file before running rsync daemon!!

uid = root gid = root #use chroot = no max connections = 3 #syslog facility = local5

[ks] path = /var/www/html/ks comment = Kickstart read only = no auth users = kickstart hosts allow = 192.168.0.9 secrets file = /etc/rsyncd.secrets ---snip---

Note in the hosts allow above we put the IP address of the main kickstart server.

/etc/xinetd.d/rsync

Just update this file and change disable from yes to no

service rsync { disable = no socket_type = stream wait = no user = root server = /usr/bin/rsync server_args = --daemon log_on_failure += USERID } Now restart xinetd (and ensure it is turned on by default)

Then on the main server I run a script like this :

---snip--- export SLAVES="192.168.0.177" export USER=kickstart export RSYNC_PASSWORD=user

for slave in $SLAVES do ping -c 3 -w 3 $slave > /dev/null 2>&1 if [ $? -eq 0 ] then rsync -avSHP --delete --exclude "local*" --exclude "isos" /data/ks/ rsync://${slave}/ks/ fi done
