Unix Revolution

2014-07-29 -- This is not a bash-fest, I just need to keep a list of these items so I don't go off and update my OS (again) without considering the issues I ran in to. no easy support for: VPNC MP3 playback VMware Workstation Which, essentially stems from poor EPEL support (at this time) and NO rpmfusion. Which really bums me out.. I was really liking the look-and-feel of RHEL 7 workstation.  I'm sure those things will be resolved soon enough. 2014-11-07 - trying again.  Going to load RHEL 7 Workstation on my desktop to see how things going.  Criteria remains the same: hope that the VPN, MP3 and VMware Workstation now work on EL 7. No RPMfusion for EL 7?  Need to find an actual post regarding this and not some seemingly random Tweet.

There are a few other scripts/tools out there to do this.. but they all seem to have some stupid dependencies (this one is no exception). #!/bin/bash # $Id: update_firmware.sh,v 1.9 2014/04/25 18:42:55 root Exp root $ # Author: James.Radtke@company.com # Purpose:  Script to download and apply firmware updates # Status:   Stable, but likely needs some work # TODO:     I would like to require a flag to run the REBOOT REQUIRED updates # Maintained at:   rhnsat01:/root/bin/update_firmware.sh #         # #  VARIABLES # FIRMWARE_LOG=/var/log/dell_firmware.log PRETTYDATE=`date +%Y%m%d-%H%M` REBOOT_RECD=0 # PLEASE NOTE: EACH OF THE PACKAGES LISTED IN THE PKGS VARIABLES ARE THE #   LEAST-COMMON-DENOMINATOR FOR EACH PACKAGE.

I had run in to a situation where my Satellite had several hundred-thousand previously run scheduled jobs sitting in the history... I could delete them 25 at a time... and if I did "Select All" it would puke. So - I created the following #!/usr/bin/env python import xmlrpclib import time SATELLITE_URL = "http://rhnsat01.company.com/rpc/api" SATELLITE_LOGIN = "satadmin" SATELLITE_PASSWORD = "notMyPassword" client = xmlrpclib.Server(SATELLITE_URL, verbose=0) delete = 1 key = client.auth.login(SATELLITE_LOGIN, SATELLITE_PASSWORD) ############################### # CHANGE THINGS AFTER THIS LINE # ## Delete all Failed Actions x = "Deleting all Failed Actions" print(x) failed_list = client.schedule.listFailedActions(key) action_ids=[] for action in failed_list:     action_ids.append(action['id']) archive_result=client.schedule.archiveActions(key,action_ids) ## Archive all Completed Actions ## Generate a

My environment does not see a lot of general maintenance or attention in particular ways.  I will occasionally find something that is either causing us grief, or about to... One of those items is the size of my Satellite Database.  The size is now an issue as I hope to upgrade to Red Hat Satellite 5.6 and migrate to Postgres in the process (yeah!). Some folks have recommended: * remove unused channels (seems logical enough) * remove unused/older snapshots I'm fairly certain that nobody else in my environment knows or realizes that snapshots even exist, let alone why they are advantageous.  Therefore, I intend to truncate the snapshots to only include those created in the last 4 months. #!/usr/bin/expect -f # # Expect and autoexpect were both written by Don Libes, NIST. # set force_conservative 0  ;# set to 1 to force conservative mode even if                           ;# script wasn't run conservatively originally if {$force_conservative} {         set send_slow {1 .
