Hi guys, Im using rroberts' bash script to remotely deploy universal forwarders using Amazons EC2 servers (thanks Mr Roberts!), the script throws up and error when it gets to the tar section, it looks like permissions issue but im not sure what permissions to look at, can anyone help me fix this please?
Im using the ec2-user for both source and destination machines and just to point out that i cant create a file on the destination machine without using sudo. Below is my script:
#!/bin/sh
# This EXAMPLE script shows how to deploy the Splunk universal forwarder
# to many remote hosts via ssh and common Unix commands.
# For "real" use, this script needs ERROR DETECTION AND LOGGING!!
# --Variables that you must set -----
# Populate this file with a list of hosts that this script should install to,
# with one host per line. This must be specified in the form that should
# be used for the ssh login, ie. username@host
#
# Example file contents:
# splunkuser@50.xx.xx.xx
# splunkker@50.xx.xx.xx
# HOSTS_FILE="$HOME/whereToInstallUF"
HOSTS_FILE="/opt/splunk/bin/scripts/whereToInstallUF"
# This should be a WGET command that was *carefully* copied from splunk.com!!
# Sign into splunk.com and go to the download page, then look for the wget
# link near the top of the page (once you have selected your platform)
# copy and paste your wget command between the ""

# Set the install file name to the name of the file that wget downloads
# (the second argument to wget)

# After installation, the forwarder will become a deployment client of this
# host. Specify the host and management (not web) port of the deployment server
# that will be managing these forwarder instances.
