[SLUG] Replicate Production to DR file system with rsync
Hi All, I've googled this one for a while and can't find any examples of people doing *system* file sync with rsync. So I thought I'd throw it out to the collective wisdom of SLUG. Here's the full story. We have a SuSE-based production application/DB server pair and a corresponding pair in a disaster recovery location (offsite, bandwidth consumption needs to be minimised). We need to sync a number of files between these servers and some require elevated (root) privileges at *both* ends. Here lies the problem; we don't allow remote root logins (via SSH or any other method either...sudo, console or nadda). I want to use rsync because of it's ability to transfer differential/incremental changes and thus bandwidth friendly, however any other tool would be fine too. However, due to the inability for root to login directly, how the heck do I synchronise particular files in privileged locations (like /etc/shadow)? I can start whatever services I need at either end (like an rsync server) but the main thing is all files maintain the same owner/group/mode at each end. Ideas?

[SLUG] SLUG FebruaryMonthly Meeting - Python Game Programming *Tutorial*
You can read the full version of this announcement at http://slug.org.au/node/123 == Summary == Date: Friday 29nd of January (Friday next week). Start Time: Arrive at 6:15pm for a 6:30pm *sharp* start Format: Python Game Programming, BOFs, Pizza Dinner Where: Google Australia, opposite Star City *** You will need a setup laptop to participate in this tutorial. ** * Instructions for setting up your laptop are listed at http://wiki.slug.org.au/pythonprogrammingsetup == SLUG January Monthly Meeting == Instead of running two 45 minute talks will be having two Python game tutorials. At the end of each tutorial you should have a fully playable game developed and running! The first tutorial will be suitable for beginners of all ages, no programming experience will be required. The tutorial will focus around a Punch the Monkey game, but there should also be enough meat for more advanced people to create something cool. The second tutorial will be suitable for people who want to advanced further and will concentrate on extending skills learnt in the earlier tutorial. Some programming experience is recommended for this tutorial. During this tutorial people will create a clone of either space invaders or asteroids. As the tutorials will be interactive you will need to bring a laptop. You will also need to set-up your laptop with the appropriate software. The software runs on Linux, Mac and Windows. You will need to install: * Python - http://python.org * Pyglet - http://pyglet.org * Rabbyt - http://matthewmarshall.org/projects/rabbyt/ To test that everything works, I have included a small Python program which will display It works if everything is working. To do so on Ubuntu, you would use the following commands; # Install python and easy_install apt-get install python python-setuptools # Install pyglet and rabbyt easy_install pyglet easy_install rabbyt # Test everything is working python test.py If you figure out instructions for other operating systems or Linux versions please add them at: http://wiki.slug.org.au/pythonprogrammingsetup *** If you have problems, please turn up **early** so we can fix them! = Meeting Details = SLUG is the very mis-named Sydney Linux User Group. We are a general Open Source interest group which runs our primary event on the last Friday of every month (except December). Meetings are open to the general public, and are free of charge. Our venue is Google, Level 5, 48 Pirrama Road, Pyrmont. It's across the road from Star City Casino. A map of the area can be found here[1], and public transit directions are at [2]. Appropriate signage and directions will be posted around the building. You will need to sign-in to enter the venue. This can be performed when you arrive, but to save time we recommend that you do so online beforehand at Eventbrite ( http://slug.eventbrite.com ). If you are unsure, please sign up as a 'maybe'. This allows us to organise adequate meeting space and facilities. You do not need to create an account to indicate your attendance. = Meeting Schedule = We start at 18.30 but we ask that people arrive at least 15 minutes early so we an all get into the building and start on time. Please do not arrive before 18.00, as it may hinder business activities for our host! See here[5] for an explanation of the segments. * 18.15: Open Doors * 18.30: Announcements, News, Introductions * 18.45: General Talk * 19.30: Intermission * 19.45: In-Depth Talk * 20.30: Dinner BoFs and the Hackerspace run from the time the doors open. = Bird of a Feather (BoF) Sessions = The list of BoFs at the moment are: * SLUGlets - our regular forum for newbies and desktop users If you would like to run a BoF, please discuss on the SLUG Activities mailing list[4]. = Hacker Space = We have heaps of room available to us at Google. If the talks do not grab you, feel free to come along and hack away on your favourite project in the designated Hacker Space. = Dinner = For dinner, we order in a selection of pizzas. The cost is $10 per head, and we will be collecting money from the beginning of the meeting. If you have any particular dietary requirements (e.g. vegetarian), let us know beforehand. Dinner is a great way to socialise and learn in a relaxed atmosphere :) For those who want to continue the conversation after dinner, some of us will be heading to a pub in the local area.

Not only that, but you can restrict sudo to only be able to run certain commands -- rsync being the case in point. Something like the following oughta do the trick (assuming you have a group called 'backup' that the backup user is in — remove the % to make it refer to a user instead): %backup NOPASSWD: ALL = /usr/bin/rsync -ar server1:/vital_data/ /vital_data/ (The above should enforce that rsync is only called with those particular parameters, if I read the sudoers man page correctly.) signature.asc Description: This is a digitally signed message part -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html

I can start whatever services I need at either end (like an rsync server) but the main thing is all files maintain the same owner/group/mode at each end. Ideas? Just use root, if you want to go down this path. Alternately, I would suggest using something like puppet which is designed to do system management like this in an automated fashion; it is a completely different approach, but one that will probably solve your underlying problem without needing to change your security model so much.
