Distributing Images - Novell SLRS 8 Admin Manual

4.6.1 Distributing Images

New or updated images are pulled from the individual branch servers by a
script (working title: posImageTrans.pl) using RSYNC. This procedure can
be triggered in two ways:
The script is started locally on a branch server by an administrator.
The script is started locally on a branch server by a cronjob.
The possyncimages.pl script initially checks via PID file to see whether an
instance is already running. After the completion of the transfer, new im-
ages are registered in the branch server object in LDAP. The image file is then
copied from the RSYNC directory into TFTP root. During this process, the
TFTP server must be stopped or otherwise prevented from transmitting this
file to clients. If a branch server has received a new image, new configuration
files are generated from the LDAP data on the branch server for the CRs of this
type. Steps should be taken to ensure that these actions are not taken during
the boot window (in the morning), but rather at night.
