Hello - First of all I like to thank Morgan Smith from this group for his h=
elp in getting the script running using SFTP. The script was tested on a RH=
EL5 server, running as a virtual machine. This script requires additional =
perl modules.=0A=0AHere is the complete listing:=0A=0A#!/usr/bin/perl -w=0A=
# This program transfers files from the host on which it is run to a series=
of=0A# hosts as specified in a configuration file, push.ctl.=0A#=0A# Autho=
r Ralf Wiegand <my...@my...>=0A# 2002/02: The script was born with=
FTP services only and limited error checking.=0A# 07/26/07 Ralf - Added SF=
TP - Secure File Transfer Protocol to the push script. This will keep the =
current=0A# data structure from the push.ctl file intact.=0A#=
07/27/07 Ralf - fixed overall structure for better readability and added p=
roper variables assignments; added use strict and use warning=0A# =
Changed to new logic and included testing via unless and eval.=0A# 07/=
30/07 Ralf - Changed if-else-logic, so if a file doesn't get transfered, it=
(the file) will not get deleted.=0A#=0A=0A# Declare perl modules=0Ause Net:=
